Gastric Bypass Surgery in Turkey is one of the most common types of bariatric surgery that combining restrictive and malabsorptive procedures. a Gastric bypass is a surgery that helps you lose weight by changing how your stomach and small intestine handle the food you eat.

Gastric bypass surgery refers to a technique in which the stomach is divided into a small upper pouch and a much larger lower “remnant” pouch and then the small intestine is rearranged to connect to both. And Unlike sleeve gastrectomy, the remnant of the stomach will not be removed.

As a result, food does not enter into the remnant section of the stomach while the gastric juice and enzymes are still produced in this section to contribute to the digestion and absorption of the food. In this way, patients who have undergone the gastric bypass procedure lose weight as they eat less and the calorie intake is limited as a result of the smaller size of the stomach while the absorption of high-calorie nutrients is also reduced as a result of a direct connection between the remaining pouch and the small intestine. Therefore this procedure can help losing weight by two different mechanisms.

The Gastric bypass procedure is performed by laparoscopy and is not associated with deep skin incisions or pain. The procedure is performed under general anesthesia and on average, The surgery lasts for one hour.

A full evaluation is performed prior to undertaking a gastric bypass, and the patient is consulted by a number of specialists, including pulmonologists, anesthesiologists, psychiatrists, and endocrinologists. Patients are given a leak test on Day 2 and can be discharged from the hospital on Day 3.

Types of Gastric Bypass surgery 

There are currently three primary gastric bypass surgeries being performed in Turkey. They are Roux-en-Y gastric bypass, a mini gastric bypass, And the standard gastric bypass surgery. 

All weight-loss surgeries have pros and cons, and none of them is a quick, simple fix for losing weight. With each procedure you still must follow a diet and exercise program in order to have good results, a gastric bypass surgery is just a tool to assist in the weight loss process.

Roux-en-Y gastric bypass: is both a restrictive and mal-absorption surgery. Patients undergoing the Rny Gastric Bypass procedure have a new stomach pouch that limits the quantity of food they may eat and makes them feel full when only a little amount of food is consumed.

Your digestive system is rerouted to bypass the majority of your stomach and a portion of your small intestine. You absorb fewer calories and nutrients from the food you eat as a result of the bypass (mal-absorption).

A mini-gastric bypass: is less invasive, And easier for the surgeon to perform, However, this technique causes bile and pancreatic enzymes to escape from the small intestine into the esophagus, and sometimes it causes severe inflammation and ulceration in the stomach residue and esophagus. If there is any leakage into the abdomen, these corrosive fluids can cause serious complications.

What are the differences between laparoscopic and endoscopic gastric bypass surgery?

Laparoscopic gastric bypass surgery results in effective and long-term weight loss. Due to the lowered new gastric bags, patients only experience immediate satiety with considerably smaller meals, similar to volume-limiting operations. Laparoscopic Gastric bypass is a surgery that combines volume-limiting and absorption-reducing features.

Endoscopy is one of the most commonly used bariatric surgical procedures, and its efficacy is one of the most important aspects in the treatment of obesity and obesity-related health problems.

When compared to laparoscopic surgery, this minimally invasive same-day procedure results in less weight reduction at 6 months, despite the fact that endoscopic gastric bypass shrinks the stomach lumen to a size equal to laparoscopic And often endoscopic procedure is used as a solution to bypass patients needing a revision procedure or regained weight.

However, patients’ health conditions vary from one another. As it will affect the stages of surgery and determine the appropriate treatment for you. 


In general, you are eligible for gastric bypass if you are overweight and have a history of multiple attempts of losing weight with diet, 

As excess weight often endanger the health people, patients between the age 18 and 65 years, Have a body mass index (BMI) of 40 or higher, or have a BMI between 35 and 40 and any obesity-related condition  including insulin resistance, sleep apnea, heart diseases or joint disorders are the often candidates for gastric bypass surgery.

Furthermore, a gastric bypass treatment can be performed as revision surgery for those who have previously had a sleeve gastrectomy, gastric plication, or gastric banding and have regained weight following the procedure.


Gastric bypass is a perfect means to achieve long-term weight control by reducing the appetite and allowing small portions of food. Most patients successfully lose weight and maintain their excess weight loss in long term.

Weight loss provides permanent resolution of obesity-associated co-morbidities, notably diabetes mellitus type 2. The rates of postoperative patient satisfaction are high in terms of psychological and physical effects.


The gastric bypass treatment, like any surgical procedure, has possible risks and complications. These potential complications, however, are rare and measured, and an experienced surgeon and team can often prevent any difficulties from developing.

The most known complications include: 

anastomotic leakage



These complications are more likely to occur during the first 15 days after surgery.

And Staple line leakages are the most serious complications of this procedure. Signs and symptoms of a leakage include:

  • High body temperature.
  • severe abdominal pain.
  • a high pulse rate. 
  • chills and fatigue.

A Timely and successful intervention of your doctor is the key to the treatment of potential leakage. The detection and treatment of leakage are quite easy for an experienced bariatric surgeon. However, such complications will prolong the healing process.

Thus Please contact your doctor immediately after becoming aware of the first signs of such complications as early detection may decrease treatment duration and may have a positive impact on treatment outcomes.

Different complications you should be aware of:

  • Embolism:

Any surgical operation can be associated with an embolism risk; however, the risk of embolism is increased in bariatric surgery procedures related to excessive weight.

Patients have to wear compression stockings and receive blood thinner injections at home for an additional 10 days after their discharge from the hospital. To reduce the risk for embolism. 

  • Bleeding

As the most common complication of the procedure. the signs and symptoms of bleeding include fatigue, dizziness, and low blood pressure.


The treatment of bleeding consists of blood transfusions according to the amount of the bleeding and this complication can be easily overcome.

  • Rapid gastric emptying:

also called ‘Dumping Syndrome’ may occur as a result of the very rapid passage of food, particularly sugar into the small intestines.

Symptoms of dumping syndrome appear 10 to 30 minutes after the food intake and include abdominal pain, cramps, and diarrhea. Dumping Syndrome may be avoided by eating smaller meals and limiting high-sugar food.

In addition, Patients should undergo blood tests regularly after the surgery to check if such deficiencies to the complications mentioned above. 

Vitamin and mineral deficiencies may occur as a result of inadequate nutrition and absorption and should receive medications and supplements prescribed by their doctor.

Gastric bypass mortality and risk

As with all obesity surgery, where stomach and bowel operations are performed, intra-abdominal inflammation may occur due to failure in the procedure, inability to heal the sutures adequately.

This condition is also known as leakage after tube stomach surgery. With early diagnosis and treatment of intra-abdominal inflammation, this process can be treated without harming the patient. In many cases, intra-abdominal inflammation is not fatal if you reach your doctor and be under supervision. 

A Gastric bypass surgery is a full-time job with technical distinctions from other gastric procedures. Make sure When selecting Gastric bypass specialists, it is critical to consider whether their team includes nutritionists and a psychologist who will oversee your post-bariatric surgery. 

Furthermore, hospitals that provide the surgery should be well-equipped, and their teams should be sufficiently experienced.

And In revision procedures after initial bariatric surgery, fistula rates can rise up to 20%. Critical areas for leakage are the uppermost point (89%) of the stapler line located in the esophagus-stomach Junction and the connections between successive cartridges. Postoperative leaks are classified as acute, late, very late and chronic.

How many pounds can be lost with Gastric Bypass Surgery?

Gastric bypass surgery is one of the surgeries that lose weight in the most and best way out of all Obesity Surgery. A person who has undergone this operation begins to lose weight at a certain level the day after the operation and continues to increase in the following days. After gastric bypass surgery, it is expected that excess weight will be lost by about 75-80 percent over a 1.5-year period. But it should be noted that since individuals ‘ eating habits have recovered over this period of about 1.5-2 years, there may be reuptake of about 10-15 percent of the given weight.

The capacity of the stomach to receive nutrients and the length of the intestines is very effective on the number of calories taken into the body. Gastric bypass operations are quite serious operations. They are only applied to obese patients. Even before application, methods such as stomach balloons can be used. 

The main thing that is done in surgery is to divide the stomach into two parts, small and large; the large part is removed from use. The second intervention is to divide the small intestine into two parts; part of it is removed from use. The operation is also completed by connecting regions outside the decommissioned areas. Gastric bypass surgery has a smaller stomach capacity.

Furthermore, the absorption process after the stomach is shortened. In other words, the number of nutrients introduced into the body from the start is reduced, and the time spent in the digestive process is shortened. Only two-fifths of the total calories consumed before surgery are used in this manner.

In the long run, significant weight loss occurs. Even if they wanted to, a person cannot eat since there is no room in their stomach. Even if there is enough room, he cannot properly digest food due to his shorter intestines. This approach mimics the effect of gastric bypass surgery on weight loss.


Following a gastric bypass procedure, patients undergo a leak test on postoperative Day 2 and a 15-day liquid diet is begins. The liquid diet period is followed by a pureed food diet and finally, solid food is introduced.

A diet plan after gastric bypass surgery varies depending on your specific condition.

And gastric bypass diet usually takes a step-by-step strategy to assist you to reintroduce solid foods. The speed with which you progress from one step to the next is determined by how rapidly your body heals and responds to the change in eating habits. 

After three months, you should be able to resume normal eating habits.

You must be cautious at each stage of the gastric bypass diet: 

  • To avoid dehydration, drink 2 liters of liquids every day.
  • Drink liquids between meals rather than with them. Drink something roughly 30 minutes after a meal and avoid drinking 30 minutes before a meal.
  • Eat and drink carefully to avoid dumping syndrome, which occurs when foods and liquids enter your small intestine quickly and in larger amounts than usual, resulting in nausea, vomiting, dizziness, sweating, and diarrhea.
  • Consume lean, protein-rich foods on a daily basis.
  • Choose low-fat and low-sugar foods and beverages.
  • Stay away from alcohol.
  • Caffeine, which might dehydrate you, should be avoided.
  • Take vitamin and mineral supplements on a daily basis, as suggested by your doctor.
  • Once you’ve progressed beyond liquids exclusively, chew foods thoroughly to a liquefied consistency before swallowing.

Gastric Bypass Results

After the completion of the operation and the completion of the careful feeding process, the first results of the operation begin to be obtained. 

The first results observed are on appetite rather than weight. As The stomach volume being ninety-five percent smaller than normal allows you to be satiated with a meal or two. At the same time, the shortness of the intestines causes the fat in your body to be burned.

And after about the fifth month, visible and measurable results are obtained on weight. It is possible to continue losing weight until the fifth year. Afterward, much more food can be consumed than normal due to the enlargement of the intestines. This results in a moderate weight gain in the long term.
