Weight Loss and weight gain Surgeries

Weight loss surgery is a solution to obese people allowing them to lose weight without putting their physical integrity at risk. This option is generally used in cases where strict diet and exercise have no effect or have serious health problems caused by obesity.

There are different types of gastric surgeries for weight reduction.

The vast majority of these are based on limiting food intake. Several others inhibit the proper functioning of absorption of nutrients.

As in any surgery, it is possible that some eventuality will occur; among these may be blood clots, hernias, and infections.

How does weight loss surgery works?

Weight loss surgery is a method to reduce the risks of obesity; however, sometimes it is also used to lose weight for aesthetic reasons.

The method of operation of these surgeries is based on two pillars

Restriction: In this process, the stomach is deformed to stop reduce the amount of food I can contain, which limits the number of fats you are allowed to eat at a time.

Poor absorption: In this surgical process, a deviation or a shortening of the small intestine is made, by shortening the digestive tract, decreasing the absorption of nutrients that the body naturally performs.

What is the most common Weight loss surgery?

Four common types of weight loss surgery:

  • Roux-en-Y gastric bypass surgery or gastric bypass surgery
  • Laparoscopic adjustable gastric band surgery
  • Sleeve gastrectomy or gastric sleeve
  • Biliopancreatic diversion with duodenal switch or duodenal switch

It is imperative that strict post-operation care is maintained after gastric surgery since weight loss is fast but it also tends to increase again over time.

To maintain most of the results obtained, it is recommended that you follow the diet and the exercises that your doctor indicates.

It is also likely that it merits clinical monitoring throughout his life.

What is weight gain surgery?

There is not an actual weight gain surgery; it would be sort of an inefficient and contrary process.

Despite what´s said. You can manage a great diet based on carbs and protein to gain more weight if you need.

You make a habit of doing proper exercises surely you will gain muscle weight so that you will weight gain without any effects.

How to Prepare for Weight Loss Surgery

What should I do before the surgery?

In order to reduce complications and optimize results, several procedures have been created to prepare for weight loss surgery.

A very common and very beneficial example is
the elimination of the cigarette,
the improvement of the respiratory tract,
Moderate and effective aerobic exercise,
but in synthesis what is desired as the main objective is pre-hospital weight loss.

One of the key preoperative phases is the inclusion of a diet to your daily life that is healthy.

That provides a fair supply of the necessary nutrients to keep the organism healthy and strong. It is possible that pre and postoperative diets are different.

Will all of this help in the process?

Yes, one of the benefits of weight reduction before the operation is the control of the size of the liver and the fat content of the abdominal tissues.

In addition to this, the surgical process is simpler. As it is previously mentioned, the requirements to be able to perform this procedure will be assigned by your doctor at the time of your pre-surgical check-up.

What Are the Risks in Weight Loss Surgery?

Will there be consequences?

Yes, one of the immediate risks in weight loss surgery and those commonly presented is a pain at the time of consuming food.

You are likely to suffer from vomiting, heartburn or stomach indigestion are also very common symptoms after this, especially if they eat food very quickly.

People should get used to eating small portions of food after surgery.

It is highly necessary to space well the times for meals and make sure you take little time.

If they do not, it is possible that symptoms develop against producers. They may even start to gain weight again.

What kind of care should I take to help myself?

After these surgeries, food tends to make its way through the digestive system faster (especially gastric bypass). Doctors call this the “rapid gastric evacuation syndrome.” It can cause nausea, weakness, sweating, cramps, and diarrhea.

Eating foods with high sugar or fat content can make this syndrome worse. Patients need to be careful about what they eat while their bodies get used to the new way of digesting food.

How should I eat to avoid the risks?

People who have had weight loss surgery may not receive all the nutrition they need.

One reason is that they are eating less.

In addition, when food does not travel throughout the digestive system, the body cannot absorb so many minerals and vitamins.

Given the above, it is very common for people to take supplements.

In exceptional cases, some people have serious problems after weight loss surgery, such as the following:

  • Bleeding
  • adverse reaction to anesthesia
  • infection near the cuts that were made for surgery
  • Infections in the stomach or intestine, which can cause an infection of the area surrounding the stomach and other organs
  • A lot of blood in the lungs or legs
  • intestinal obstruction

One of the biggest problems both before and after the operation is the mental health of the patients.

While it is true that most of them improve their self-esteem after losing weight, many continue to suffer from certain problems.

It is crucial for people who have undergone surgery to lose weight to follow up with a psychologist and receive help in cases of feeling bad or sad.

How Does Weight Loss Surgery work?

What will be happening?

A surgeon creates a small sac on the upper part of the stomach. This sack is transformed into the new stomach. The surgeons then connect the sac to the middle part of the small intestine and skip the upper part of the small intestine that is how weight loss surgery works.

After surgery, the stomach sac contains much less food than a normal-sized stomach.

The person will eat less quantity of food, will feel satisfied before and will be less hungry. Moreover, because the small intestine is shorter, fewer calories and nutrients are absorbed.

People with gastric bypass tend to lose more weight than those with a gastric sleeve, but they may also have more problems.

The gastric bypass procedure is irreversible.

Is it for everyone?

The gastric belt is not recommended for adolescent use. Weight loss surgery works in the same way as other surgeries.

This is based on making the stomach smaller.

The surgeon places an adjustable silicone band on top of it to create a small sac.

Those who have this band or belt feel satisfied faster and eat less.

The belt is connected to a port under the skin of the person.

The doctor uses this opening to adjust the size of the bag by adjusting or loosening the belt.

The belt can even be completely deflated or removed, allowing the stomach to regain its normal size.

Gastric belt surgery has fewer complications than sleeve and gastric bypass options. However, people who are placed on the gastric belt do not lose so much weight.

The FDA does not approve gastric belt devices for children less than 18 years of age.

Weight Loss Surgery FAQ

What is the recommended operation? How it is performed?

It must be discussed specifically with your surgeon. All the risks, benefits. Ways to carry it out, etc.

Each type of obese person may need a different one depending on their BMI and dietary habits.

In general, the most recommended are tubular or sleeve vertical gastrectomy, gastric bypass, and biliary-pancreatic bypass all laparoscopically.

How does weight loss work?

The simple and restrictive operations of the stomach reducing the portions of food that can be digested, since the stomach is smaller and fills up with less.

By eating less, you lose weight. The malabsorptive techniques also have a deficit component in the absorption of nutrients, mainly fats.

Does the intervention have risks?

All surgery is risky and bariatric surgery is no an exception to the rule. However, both, the technology and the experience of the surgeon have turned into an improvement for fewer complications. To this, there is a less aggressive process such as laparoscopy.

It is considered that open surgery in the morbidly obese is justified in a few exceptions. In any case, the risks of the operation are much lower than those of the untreated obesity disease. Each surgeon is in the need of explaining what the risks of every surgery are, no need to worry about that.

How much time will I stay in the hospital?

Normally between three and five days, depending on how fast you recover. The important thing will be a long-term success.

How long does it take for the operation?

It depends on each individual and the technique used. It goes from 1 hour to 5 hours.

Can the staples be removed in the future?

The staples are permanent. The rings can be removed if necessary.

All operations are reversible, but in principle, all operations are for life because if the operation is undone the patient immediately gains weight again.

Perhaps the gastric bypass is the most complex to reconvert to another technique or normality.

When can I go back to work?

Between 2 and 6 weeks. Nevertheless, you cannot lift weights to avoid hernias.

Will I have to follow a diet?

The diet after surgery is forced. That is, you cannot eat certain foods unless you change your eating habits by having to chew very well and eat slowly.

In mixed operations, dietary restrictions are minimal.

But … how much can I eat?

Initially about 50 ccs. for food. Over time, in less than 1 month, it increases to 150-250 c / c. You should eat three to five times a day and hydrate well.

If the patient ingests in a similar way as he did, in the immediate postoperative period dehiscence of the suture or staples may be caused that endangers the life of the patient and forces his re-intervention.

With so little food, will not I die of hunger?

You will be given a dietetic program to cover your nutritional needs and vitamins or other contributions depending on the surgery performed.

At what rate do you lose weight?

It depends on each person and the type of operation.

The first month they tend to lose about 10 Kg, later the most frequent is to lose 5 – 7 Kg. Each month in the beginning and then go down to stabilize the weight at 12-18 months.

What percentage of success does this surgery have?

It depends on the individual and the technique used. It is considered a success if you lose between 60-80% of overweight.

Most interventions surpass it. In some interventions, some patients recover part of the lost weight, which usually occurs after 5 years.

There is no intervention that guarantees success, but it has high probabilities.

Why the surgery?

Because the severely obese, who have tried all kinds of diets and failed, who has a “serious” disease, who has other serious medical problems (hypertension, diabetes, arthritis, heart disease, etc.) needs to lose weight and surgery is the more effective.

Do I have to worry about my weight forever?

Yes. Surgery gives a mechanical means to control what you eat and your weight, but you are not cured of your disease.

Therefore, you need your cooperation and adjust your lifestyle.

Can patient sabotage this surgery?

If you propose, yes. In some operations more than in others. It is known that obese gourmands who take salads, liquid cream and smoothies again gain their weight. Surgery is only the beginning.

What happens if I do not follow the program well?

At first, if you insist on eating you will vomit. If you eat continuously, you are going to make the stomach expand and you will gain weight again.

The most aggressive techniques such as the biliopancreatic diversion and the duodenal junction keep weight loss longer

Not necessarily if you follow the instructions. In-ring operations if you try to eat solids without chewing it can bring you problems.

In operations without rings, patients tolerate better intake and do not suffer from vomiting.

How do I stop losing weight?

When you reach the balanced weight, which in advance cannot be predicted, the organism is readjusted to the new intake and the weight is maintained.

Weight loss is from fat, but not from the noble parts of the body (muscles, vital organs like liver, kidney, heart)

Can this operation be redone again and again?

Obesity operations are permanent. All can be undone.

Some patients need re-operations if they continually “break” the staple line or make their stomach go big again.

Will I have skin flaps?

It is difficult to predict which patients will happen more, but usually yes.

It depends on the weight loss, on the elasticity of the skin and on women if they have had several children.

Will I need a dermolipectomy or body contouring surgery?

It would be excellent! It means that the operation was a success.

To improve the aesthetic results and body contour, operations are done to remove the “flaps” in the abdomen, thighs, arms, breasts.

All this is a sign that the intervention worked very well.

The surgeon who has operated on you is the one who can best tell you that it will be necessary; he can correct your abdominal, skin and breast problems

Will I gain weight again?

Yes, in fact, if you do not follow the dietary steps that your doctor requires, it is very likely that you will begin to regain the lost weight. Similarly, after the surgery process, it is normal for you to gain a small amount of weight even if you follow all the stipulated parameters.

bariatric surgery

   Generally, Obesity means who have Body Mass Index(BMI) of 30 or more. BMI is a measure of body fat based on weight and height of a person.

Look BMI class for severity:: 




Class-1 obesity



Class-2 obesity36-40


Class-3 obesity41-above


If anyone who has BMI 35 or more immediate need to take action to overcome obesity to fit so that we can have a healthy life 🙂


If you are suffering from type-2 diabetes, sleep apnea or have not been lost weight and suddenly gaining more weight with some medications or lifestyle treatment…

Bariatric surgery is the best option as per surgeons


What is Bariatric Surgery?

Bariatric surgery means helps you lose weight by making changes to your digestive system.

Will this bring more than just weight loss?

The benefits of bariatric surgery are in the resulting weight loss that can improve or eliminate type 2 diabetes.

It can help diabetes in a matter of days, even without weight loss, just by getting the surgery it may help.

Help the level of fat in the blood return to normal, which reduces low-density cholesterol or LDL (harmful), and triglycerides, and increases high-density cholesterol or LAD (beneficial).

One of the benefits of bariatric surgery is that it increases the fertility of women, particularly those with the polycystic ovarian syndrome.

This common disorder can result in diabetes, high blood pressure and an unhealthy level of blood fat. Increase man’s testosterone. Improve or eliminate high blood pressure.

Bariatric surgery (or obesity), as well as metabolic surgery, are successful therapies in patients with morbid obesity.

It is confirmed that both procedures achieve, not only a sustained weight loss, but also a substantial improvement of the diseases associated with obesity and, therefore, a reduction in mortality.

Excess weight is a risk factor for cardiovascular diseases due to association with dyslipidemia, hypertension, diabetes.

Weight loss can prevent the progression of all of them.

Obesity is considered an important risk factor for the development and progression of Sleep Apnea (repeated episodes of partial or total obstruction of the airway at the pharyngeal level while the person sleeps).

This is due to the accumulation of specific site fat that surrounds the respiratory tract.

Excess weight increases the risk of high blood pressure, which in people with obesity is between two and three times more frequent than in people with normal weight.

Weight reduction after bariatric surgery directly affects the improvement of the patient’s physical condition and social interaction.

In addition, depression and anxiety are significantly reduced.

Disadvantages of bariatric surgery?

Is there something bad I should know about this?

Bariatric surgery is not free of risks and complications, although these are minimal and they present a low percentage of presence, it is possible that they occur.

The main complications related to the intervention are those derived from infections, hemorrhages, and fistulas (leaks) of the suture that are made during the intervention.

The risk of complications ranges from one surgery to another and ranges between 3 and 6%.

Will this have side effects?

Side effects may occur that vary from one surgery to another.

The most important are: nausea, vomiting, abdominal pain and alterations of the intestinal rhythm.

In the medium and long term, the side effects that can be observed are vitamin deficits, deficiency of elements such as iron, calcium or other issues that need to be treated.

There is also a risk of regain in weight. In people with greater weight loss, can be aesthetic sequelae.

Head-to-toe Effects of Weight Loss Surgery

The effects of bariatric surgery in the short-medium term are very powerful due to weight loss and the improvement of comorbidities associated with obesity.

In the long term, the results will determine the success of the surgical indication as they will confirm.

On the one hand, the patient’s ability to control their obesity while maintaining healthy lifestyles and,

In another way, an adequate ambulatory follow-up to detect both late surgical complications as the deficits deficiency associated with bariatric surgery.

These positive or negative results will condition the expectation and quality of life of the operated patient.

On the other side of the scale, bariatric surgery can have negative effects due to the alteration of the processes of digestion and absorption of nutrients, trace elements, vitamins, etc.

So, these nutritional deficits are not usually observed after the placement of an adjustable gastric band, but its incidence is progressive as patients undergo a resection, mixed or malabsorptive technique.

The anatomical changes of the proximal digestive tract alter the absorption of iron, vitamin B12, calcium and in some patients with long intestinal loops excluded or derived, that of trace elements and fat-soluble vitamins.

What Is Mixed Surgery? (Restrictive and Malabsorptive)

Mixed techniques in bariatric surgery mix characteristics of restrictive and malabsorptive techniques.

As the restrictive techniques reduce the capacity of the stomach and additionally a bridge is made from the stomach to the distal area of the intestine so the patient has less gastric capacity.

The food that reaches there goes directly to a more distal area of the intestine preventing the complete absorption of them.

The gastric bypass is a surgical technique has a restrictive component and another malabsorptive.

The first is achieved by building a stomach of very low capacity and the second through a cross in the small intestine that will allow only 60% of it to be used for the absorption of food.

Nowadays, the best surgery for weight loss is the gastric bypass.

This surgery as mentioned above is the most effective due to its restrictive and malabsorptive capacity.

Life after bariatric surgery

How will my routine be?

Your operation has been successful, and you have followed the suggested dietary guidelines for your life after bariatric surgery.

To maintain a healthy condition and not gain weight again, you must adapt to your new life after bariatric surgery.

From now on you should be cautious with your meals, you should take care of what you eat and the portions in which you eat food.

It is important to know that this diet should be maintained for the rest of your life after bariatric surgery.

The exercise will also be a pillar in your day today.

You should adjust your routine according to what your doctor indicates; this is essential to maintain control of your weight and post-operative physical health.

After surgery, and for the rest of your life, you should have regular medical check-ups.

You should not stop going with your doctor in charge, it is possible that a long time after the operation you start to gain weight again, so it must be eradicated because the consequences can be serious.

Gastric Banding Surgery for Weight Loss

  • What is it?

Gastric banding surgery is an adjustable band (ring type) is placed around the upper part of the stomach to create a small pocket in the upper part of the stomach making the stomach smaller, which allows less food to be ingested.

Only a few tablespoons of food can fit in that bag. Food passes slowly through a narrow opening created by the band at the bottom of the cavity, making you feel full for longer.

 The size of the band is adjusted by an access port under the skin.

This port gives your healthcare provider a way to insert a needle that is used to add or remove fluid to the band.

This is done to increase or decrease the size of the opening. The adjustment of the band determines the speed with which the food leaves the cavity

What Are the Results of Gastric Banding?

Gastric banding surgery a systematic review of the studies that have been published to date, a group of researchers found that the excess weight reported with gastric banding was 45% on average, with a reduction in the rates of type 2 diabetes of 28.6 %.

The reduction in the rate of hypertension (high blood pressure) was 17.4% with a gastric band.

The reduction of hyperlipidemia (high cholesterol) was 22.7%.

Even though all the studies said different results, it was shown that the results were not constant.

These numbers were lower than those observed with the gastric bypass and gastric sleeve procedures.

Despite the evidence to date, however, more long-term follow-up studies are needed, as no study of bariatric surgery seems to report results beyond five years.

Therefore, although the numbers of initial weight loss are known, what is not known is how much weight loss is maintained for seven or ten years or even more,

so there is no certain proof that gastric banding surgery will have effects that last for a long time.

What Are the Side Effects of the gastric banding?

Some of the side effects of the gastric banding, such as “dumping syndrome” and diarrhea, associated with other bariatric surgery procedures such as gastric bypass, are not expected to be related to laparoscopic adjustable gastric banding. However, constipation may occur.

Another side effect of the gastric band is that some people may also experience dysphagia (difficulty swallowing), especially after having adjusted the band. However, some claim that it is tolerable.

Another factor to be taken into account is that the malabsorption syndrome does not happen to be a side effect of a gastric band, due to the fact that the food that is consumed eventually passes from the upper pouch to the lower pouch. where it is normally absorbed as it passes into the intestine and the rest of the digestive system.

However, due to reduced food intake (which is, after all, the point of this procedure), nutritional deficiencies may occur, and at a minimum, it is recommended that patients with gastric banding take a full multivitamin all the days.

Other nutritional supplements can be recommended based on the individual needs of the patient and close follow-up with the doctor is essential for these post-operatory businesses.

What is the Sleeve Gastrectomy?

  • What am I getting into?

The gastric sleeve or vertical gastrectomy is a laparoscopic operation with which we reduce the volume of the stomach by removing 80% of it.

This surgery does not alter the continuity of the digestive tract and has no side effects on the absorption of nutrients and vitamins from food; however, this has proven to be a very good surgery for weight loss.

The stomach is so small that is barely bigger than a banana. This limits the amount of food you can eat, making you feel satisfied after eating small amounts of food ingested.

Sleeve Gastrectomy its details?

  • What is it?

The sleeve gastrectomy may be helpful to people who are very overweight and have serious health problems due to it.

However, it is not a type of surgery that simply fixes the stomach and then you can forget about it. Not all people who would like to have surgery are allowed to take this intervention.

  • Can anyone apply?

To be considered as a candidate for a sleeve gastrectomy, a person must commit to change their habits of physical exercise and long-term nutrition. Not all people who would like to have surgery are eligible for this intervention.

Doctors consider several factors when deciding whether an operation to lose weight is the best option for a teenager. These factors include if a teenager meets the following requirements:

  • is at least 14 years old, with a height close to that of an adult person and must lose more than 100 pounds (45.4 Kg)
  • is healthy enough to undergo a sleeve gastrectomy?
  • sleep apnea, diabetes, or heart problems are medical issues that could improve with significant weight loss
  • has been able to follow a healthy diet and exercise regularly
  • has family members who will give you emotional and practical support (such as taking you to doctor visits or buying healthy foods)

How do I prepare myself for sleeve gastrectomy?

Preparing for a sleeve gastrectomy involves months of work.

Patients need to show that they can and are willing to make large changes in their eating and physical exercise habits before the operation.

For several months before the sleeve gastrectomy, you will work with the medical team to develop the skills you need to be successful. Psychologists, dieticians, trainers, surgeons, are the ideal people.

Several months before the sleeve gastrectomy, you will meet with a doctor and a surgeon.

They will explain what the operation is, they will examine you and tell you what to expect before and after the operation.

They may also inform you about some of the things that could go wrong in the operation (doctors will probably call them “complications”).

What will happen during the surgery?

Sleeve gastrectomy is a major operation. The doctors will administer anesthesia so you sleep throughout the operation.

When you are asleep, the surgeon will extract three-quarters of your stomach and leave you with a smaller stomach in the shape of a banana, which is called “gastric sleeve”.

After surgery issues?

After the sleeve gastrectomy, you will most likely stay in the hospital for a couple of nights so that the doctors and nurses can supervise your recovery.

They will give you medicines for pain and nausea, they will help you get up and move around the room and they will make sure that you can drink liquids without vomiting.

As it is major surgery, the operation of gastric sleeve involves some risks, such as the following:

  • excessive bleeding
  • loss of gastric content to the belly, from the place where the surgeon cuts the stomach
  • adverse reaction to anesthesia
  • blood clots
  • infection

How will my recovery be?

People usually recover from a sleeve gastrectomy in a week. However, it will take several weeks to return to eating the usual foods. Gastric sleeve surgery reduces the size of the stomach permanently.

For the rest of your life, you will always have to eat smaller portions. You will also fill more quickly.

To get used to having a smaller stomach, you will need to follow a special diet that will start only with liquids.

Your dietitian will give you a meal plan that will progress gradually to solid foods; for example:

  • During the first 2 to 3 weeks after the operation, you will get all your nutrition from protein-rich beverages.
  • During the next two weeks, you will eat food in the form of puree or porridge.
  • Finally, you will go on to eat soft foods for another couple of weeks before going back to eating common foods.

Since you cannot eat that much, the foods you choose to eat matter a lot.

Your dietitian will help you develop a healthy diet for life that includes fruit, vegetables, and protein.

Sweets and chips have many calories and do not provide the nutrition you need; therefore, try to avoid these foods.

Your dietitian will also recommend vitamin and mineral supplements so you do not miss essential nutrients.

If you feel a lot of pain or belly swelling or you vomit a lot, call your doctor immediately. It could indicate a problem that requires medical attention.

When a person undergoes a sleeve gastrectomy, he is making a huge change in the way his body relates to food.

It may take a while to get used to the new normality of your body. Apart from eating a sensible diet, physical exercise is a fundamental part of being healthy and maintaining weight loss after the operation.

People who follow the recommended diet and exercise program often lose a good amount of weight in the months after gastric sleeve surgery.

Afterward, the weight begins to stabilize. Your team of specialists will continue to see you for several months after surgery to monitor your diet and your health, and to help you follow the treatment well.

What Is Vertical Banded Gastroplasty?

The vertical gastroplasty with a band, which is also known as stomach stapling, is a surgery that is done to reduce the stomach.

Your doctor will explain how to prepare for surgery. It can tell you not to consume any food or drink after midnight on the day of surgery.

Following all this, it is likely that you will also be told what medications you can take the day of surgery in order to avoid complications at the time of the operation.

The surgeries that are restrictive, such as vertical banded gastroplasty (VGB), serve only to limit and decrease food ingest and do not interfere with the normal digestive process.

This benefits weight loss quickly and effectively, however, if neglected in your daily life will regain all the weight you lost.

In this procedure, the upper portion of the stomach near the esophagus is stapled vertically to create a small pouch along the inside curve of the stomach.

The outlet of the bag is restricted to the rest of the stomach by means of a band made of special material. This band delays the emptying of food from the bag, causing a feeling of fullness, this will cause you to eat less, and help you lose weight.

Several incisions will be made in your abdomen by the surgeon. He will insert a laparoscope and other surgical instruments through these incisions.

Your surgeon will use a soft band and staples to form a small stomach pouch.

He will place the band on the bottom of this bag and create a small opening.

The food will pass to the rest of the stomach through this opening. Your surgeon will close the incisions with sutures or staples.

Diet recommendations for bariatric surgery

Surely, you will hear testimonies from people who speak wonders of operations to reduce weight, but not everything is so beautiful. Keep in mind that an operation “always” involves risk, especially if you have general anesthesia.

In addition, it is not about operating and continuing with our lives as before.

These operations also have post-operative diets and specific dietary recommendations.

You also have to take into account that you have to meet a series of requirements for some operations, not worth losing those extra kilos, this type of operations are usually done when obesity already poses a big risk to the patient’s health.

Of course, we always recommend changing life habits to lose weight, although we also know that there are difficult cases that require surgery, they are usually the least and require a great commitment for the surgery to be effective over time.

The feeding recommendations after gastric surgery vary depending on your individual situation.

A gastric bypass diet usually follows a systematic approach to help you return to eating solid foods gradually.

The speed with which you pass from one stage to the next depends on how quickly your body recovers and adapts to the change in eating patterns. In general, you can start eating normal foods about three months after surgery.

At each stage of the gastric post-bypass diet, pay attention to the following:

  • Take 64 ounces of fluid per day to avoid dehydration.
  • Drink fluids between meals, not with meals. Wait about 30 minutes after meals to drink and avoid drinking 30 minutes before meals.
  • Eat and drink slowly to avoid rapid gastric emptying syndrome, which occurs when food and fluids enter the small intestine rapidly and in larger than normal amounts and cause nausea, vomiting, dizziness, sweating and diarrhea.
  • Eat lean and high-protein foods daily.
  • Choose foods and drinks that are low in fat and sugar.
  • Avoid alcohol.
  • Limit caffeine, which can cause dehydration.
  • Take vitamin and mineral supplements daily as directed by your healthcare provider.

Once you have passed the liquid stage only, chew food thoroughly until you obtain a puree consistency before swallowing.

During the first day after surgery, you will only be allowed to drink clear liquids. Once you are well with clear liquids, you can start taking other liquids, such as:

  • Broth
  • Juice without sugar
  • Decaffeinated tea or coffee
  • Milk (skim or 1% fat)
  • Gelatin or ice cream popsicles without sugar

After about a week of tolerating fluids, you can start eating strained and pureed foods. The food should have the consistency of a soft paste or a thick liquid, without solid pieces of food in the mixture.

You can eat three to six small meals a day. Each meal should consist of 4 to 6 tablespoons of food.

Eat slowly: each meal should last approximately 30 minutes. It should be a bit difficult at the start, but with the pass of time.

Chewing in the mouth and slowly eat food more than 30% of digestion takes place in mouth and digestion goes very smoothly and make you very healthy.

Moreover, it will be easier for you to follow the correct diet for your recuperation and new fat-free life.

New weight loss surgery options

Needless to say, bariatric surgeries or surgeries to treat obesity are operations that always have to be recommended by specialized medical personnel, they are not operations that are done on a whim or to take a shortcut to lose weight.

There are several methods or operations that can be done to lose weight, many have been reinvented to give greater and better results, in areas such as duration or recovery time.

These operations are not the panacea and work for life, you need to adopt a healthy lifestyle so that the lost kilos do not return to win over the years.

Yes, slimming operations are effective, but they also have risks and require a commitment to change lifestyle, if not, they are useless. Let’s see one by one the different operations:

Intragastric balloon

It consists of introducing a saline ball inside the stomach with the intention of having the volume of it.

By decreasing the gastric volume, the sensation of satiety appears before, thus decreasing the daily intake of food.

The operation is quite safe, does not require hospitalization, anesthesia or usually has complications.

The deflated balloon is introduced by endoscopy and, once inside the stomach, if it is inflated with saline and the valve is sealed.

Although there is already a more advanced method: the invisible intragastric balloon. It would be enough to swallow a capsule attached to a thread. Once in the stomach, the balloon would swell. A much less aggressive method.

The balloon is left in the stomach for 6-8 months and usually loses an average of one kilo per week, although it depends a lot on each person.

In this time, in addition to losing weight because we eat less, the key is to reeducate the eating habits so that when the ball is removed, we are able to maintain the weight

The purpose of the intragastric balloon is to reduce the volume of the stomach.

In this way, when we eat the sensation of satiety appears before and, therefore, we limit the amount of food we consume per day. This, undoubtedly, facilitates the process of weight loss.

Taking into account that most cases of obesity are due to overfeeding, that a person does not feel that sense of wanting to continue eating because he is satisfied, is an important help to reduce weight.

Therefore, the intragastric balloon will be responsible for producing early satiety.

Once the doctor has checked with the gastroscope that there are no abnormalities in the stomach, the patient is sedated and the intragastric balloon is introduced deflated to the stomach by endoscopy.

Once in the stomach, it is filled with saline and its valve is sealed.

Depending on the weight and height of the patient, the balloon swells more or less but usually occupies between 40 and 50% of the total volume of the stomach.

The placement of the balloon, therefore, is a fairly safe intervention and lasts about 20-30 minutes, does not require hospitalization.

For the removal of the balloon, the intervention is similar, but in reverse: the balloon is punctured and taken out of the stomach by endoscopy.

At present, there are intragastric ingestible balloons, where it is not necessary to do an endoscopy to place them: a capsule is swallowed together with a thread and, once in the stomach, it swells.

Once the balloon is implanted, one of the side effects that may appear but that is transient is nausea and, occasionally, vomiting in the first 24-48 hours.

Other uncommon complications may be due to irritation of the stomach mucosa or gastritis, ulcers or perforations.

Complications that if there is a medical follow-up are usually identified quickly and do not reach serious complications.

If the procedure of placement and removal is normal and the materials used and professionals are adequate, complications of the intragastric balloon are minimal.

If a person is very aware of losing weight, he will not need an intragastric balloon, only professional help to redirect his diet and daily habits.

Now, if that overweight is a serious health problem or the person is unable or very unmotivated, the ball may be an option to assess.

But, in any case, the intragastric balloon should be taken as a quick means of weight loss without intending to change habits, because its effects will be very long term and we will soon return to the initial state of obesity.

Gastric plication

This operation is similar to the previous one, in contrast to the fact that there is no gastrectomy but gastroplasty, when the stomach is folded on itself, reducing the volume of the stomach, but preserving it in its entirety.

The stomach retains all its functions and is reduced by 75-80% its volume.

It does not require hospitalization and is a reversible method, normally the points are removed after a year and a half or two years.


We can consider this operation an aesthetic operation, since it does not affect the digestive processes, but it directly removes excess fat and skin from the abdomen, which is usually the part where it accumulates the most.

This operation requires general anesthesia, and there is no laparoscopy, it is a more invasive method where the skin of the abdomen is released with a scalpel, removing the excess of fat and skin, even the abdominal muscles are reinforced with sutures if they are very flaccid

The operation usually requires general anesthesia, lasts about 2-4 hours and after the operation, you have to wear a girdle for greater support of the area. Here, although in a minimal way, there are scars and it takes a while for the abdominal shape to be homogeneous.


This can also be considered an aesthetic operation. It is the best known when it comes to removing fat from the middle, but it does not help if after liposuction we continue with bad eating habits, since nothing is involved in the digestive system.

It basically consists of extracting fat through a syringe that sucks it.

Here the problem is that, before a major reduction of fat, the skin is left over and aesthetically it does not look good, so we will have to do another operation to reduce that excess skin.

It does not require hospitalization processes and anesthesia is local, so it is a few hours we can remove a few kilos of fat in the middle, a highly recommended operation for fast and effective weight loss.

In spite of how simple this procedure is, it is important to emphasize that you should still have a medical check before doing it.

This is not mandatory but it is recommended to avoid complications.
