Obesity Surgeries


What is Obesity Surgery?

Weight loss surgery, also called obesity surgery or bariatric surgery, can help to achieve significant weight loss and resolve obesity-related health problems, such as type 2 diabetes, sleep apnea or hypertension. There are various surgical options based on restricting the amount of food you can consume or reducing the ability to absorb nutrients, or a combination of both. Surgery for weight loss can be a life-saving option for people with severe obesity, but at the same time it is a major procedure that poses certain risks and side effects. At Acibadem, we perform an extensive evaluation with a multidisciplinary team of experts before initiating a bariatric surgery, to ensure that each patient receives the medical procedure that is right for him.

Over the past decade, weight loss surgery has been continuously refined to improve results and reduce risks. Since obesity is associated with a higher risk of complications during surgery, Acibadem patients can benefit from the robotic surgery option. The procedure is performed with the “da Vinci” robotic system which is called ‘robot-assisted laparoscopic surgery’. Surgical interventions with robotic surgery on obese patients reduce the blood loss, risk of infection, scars and recovery times.

Nowadays, there are various options for bariatric surgery. The most preferred weight-loss surgeries today are Gastric Balloon, Sleeve Gastrectomy, and Gastric Bypass.

Gastric Balloon

  • Non-surgical procedure
  • Performed endoscopically
  • Expandable silicone balloon placed in the stomach to reduce its volume.
  • The balloon is inserted via a gastroscope (camera) that enters through the mouth, using a minimally invasive procedure.
  • 1-night hospital stay
  • The gastric balloon needs to be removed 6 to 12 months later.
  • The Gastric balloon is appropriate for patients with BMI of 30 to 40. It is also effective in helping obese patients lose some of their weight and reduce surgical risks before obesity surgery.
  • Gastric balloon
    (1 day hospitalization)

    • Day 1: The endoscopic procedure takes 20-30 minutes, followed by 3-4 hours of surveillance. Hospital stay.
    • Day 2: Discharge
    • Day 3, 4: Control

    3-Day stay in Turkey is usually enough. Aftercare: Dietary and lifestyle recommendations must be followed.

Gastric Bypass in TURKEY

Gastric Bypass

  • It is a surgical procedure for weight loss.
  • It involves creating a small pouch from the stomach (of approximately 30-50 cc) and connecting it directly to the small intestine.
  • Performed laparoscopically.
  • Gastric bypass can be an appropriate option for patients with BMI above 40, as well as some patients with a BMI between 35 and 40 with serious obesity-related health issues.




Procedural Steps:

  1. The stomach is divided with a laparoscopic stapler. Most of the stomach is no longer attached to the esophagus and will no longer receive food. Your new stomach is much smaller and shaped like a small tube.
  2. Between 2 to 7 feet of intestines are bypassed. The surgeon will attach the remainder of the intestines to the new stomach.
  3. Food now flows into your small tube-like stomach and then bypasses between 2 to 7 feet of intestines where it resumes the normal digestive process in you’re the remaining intestine.

Benefits of Mini Gastric Bypass Compared to Gastric Bypass Surgery

  1. Shorter operating time.
  2. Less re-routing of the intestines.
  3. One fewer anastomosis (connection of intestines), which in theory means less chance of a complication.
  4. Technically easier for the surgeon.
  5. Similar weight loss and recovery.

Additional Risks With Mini-Gastric Bypass Compared To Gastric Bypass

  1. Severe acid-reflux. Because the pouch is small and the remainder of the stomach is still connected to the intestines. It is possible for gastric juices to travel down the intestines and into the new pouch.

Recovery, Pain and Complications

Recovery, pain and complications are very similar to traditional gastric bypass and gastric sleeve surgery.


Are you considering gastric sleeve surgery because you’ve tried diets and exercise for years and still have a lot of weight to lose? You’ll want to know the risks and benefits, what makes someone a good candidate for the operation, and what long-term commitments you need to make to keep the results.

Sleeve Gastrectomy

  • It is a surgical procedure that is performed as laparoscopic or robotic sleeve gastrectomy
  • About 70% to 80% of the stomach is removed and leaves the stomach like a shape of a banana.
  • Removal is permanent and irreversible.
  • 3-day hospital stay
  • Rapid weight loss and health improvement without affecting food absorption.
  • It is appropriate for patients with BMI above 40; it may also be applied to patients with a BMI between 30 and 40 with serious obesity-related health issues

The first day after surgery, you’ll drink clear liquids. By the time you leave the hospital, you can eat pureed foods and protein shakes and will continue to do so for about 2 weeks.

Keep in mind that you have to change the way you eat forever. After that 15 days, you’ll switch to eating soft solid foods very slowly. Other pointers to keep in mind:

  1. Everything must be chewed thoroughly before being swallowed.
  2. Don’t drink while you eat, as this might cause your new stomach to overfill.
  3. Drink liquids a half-hour after finishing a meal.
  4. Avoid high-calorie sodas and snacking.
  5. Take vitamin and mineral supplements every day.

After 1 months, you can move on to regular meals. But remember, you will not be able to eat as much as you used to.

In what cases is obesity surgery applied?

Obesity surgeries are not performed for aesthetic purposes, that is, to make the person look weaker.

In order to be a candidate for gastric reduction surgery, the person must meet the definition of “morbidly obese”.
Body Mass Index (BMI) calculation, which is set by the World Health Organization, determines the degree of obesity by dividing your weight by the square of your height value (kg/m²).

For gastric reduction surgery, your BMI, which is calculated depending on your height and a weight value, is important, not how much you weigh.

According to the BMI calculation, the candidates for obesity surgery are those with a body mass index above 40 kg/m² (morbidly obese, i.e. severely obese). Those with a BMI of 35-40 and problems such as type 2 diabetes due to excessive obesity, hypertension and sleep apnea are also considered morbidly obese and may need to have gastric reduction surgery. In addition, patients with “new” type 2 diabetes and metabolic disorders due to obesity and whose BMI is between 30 and 35 can be operated on by the decision of the obesity doctor. In order to be a candidate for obesity surgery, patients must have tried to lose weight at least 2 times with dietary therapy and for at least 6 months, but have not succeeded. Because morbidly obese people are 2 percent more likely to lose permanent weight through diet and exercise. Obesity surgery is considered the most effective treatment option for morbidly obese patients who have failed diets as mentioned. However, despite diet, exercise, and psychological support in morbid obesity, diet may not work in the long term in 98 percent of patients because it is difficult obesity to eliminate.
