What is bariatric surgery?

First of all, by the technical definition of obesity, people with a body mass index (BMI) above 30 have obesity.

Obesity surgery (bariatric surgery) involves a group of surgical methods targeting the digestive system in overweight people who have not reached safe weight limits with a diet and exercise program. This surgery restricts the amount of food to be taken and aims to reduce the absorption of food.

It is performed by entering through 4 or 5 small incisions in the abdomen with the laparoscopic method. The laparoscopic method has some advantages over open surgery.

  • Smaller size incision area and scars
  • Discharge in a shorter time and returning to daily life
  • Less pain
  • Fewer complications

Are you suitable for obesity surgery?

  • You are suitable for obesity surgery if you have
  • Health problems caused by obesity
  • Food addiction
  • Depression
  • Obesity discrimination
  • Relationship problems
  • Poor self-image
  • If you are between the ages of 18 and 75
  • If you have a health problem caused by obesity
  • If you have a history of unsuccessful weight loss attempts (unsuccessful diets)
  • Obesity surgery is an important operation for losing weight, but it should be remembered that it is only a tool. This operation requires long-term diet and lifestyle changes to have permanent effects.
  • Body mass index (BMI) of 40 or more,
  • or a BMI of 30 to 39.9, which indicates a serious health problem related to obesity, such as diabetes, high blood pressure, sleep apnea, high cholesterol, joint problems, or others
  • or 30 to 40 BMI with or without health issues for the gastric balloon procedure.

Body mass index (BMI)Concomitant health problems considered for the operation decision
30 – 34.9The patient may be suitable for Gastric Balloon. This BMI range may also be suitable for other procedures if the patient has poorly controlled diabetes or metabolic syndrome.
35   – 40The patient may be suitable for Gastric Balloon. This BMI range may also be suitable for other procedures if the patient has poorly controlled type 2 diabetes, a higher risk of cardiovascular disease, or another weight-related health issue.
40.1 – 45The patient may be suitable for Gastric Balloon. This BMI range may also be suitable for other procedures if the patient has poorly controlled diabetes or metabolic syndrome.
45.1  – 55Any weight loss procedure can be applied except Gastric Balloon.
Over 55Any weight loss procedure can be applied except Gastric Balloon.

These criteria apply to most countries and most procedures, including the USA, Canada, Australia, and the UK.

What are obesity surgeries?

- Laparoscopic Sleeve Gastrectomy

Laparoscopic sleeve gastrectomy is the removal of a large part of the stomach that serves as storage. Thus, the stomach, which normally has a volume of 1.5-2 liters, is transformed into a thin tube of approximately 30-150 ml. As in vertical banded gastroplasty, it is not possible to place a foreign object in the abdomen. The goal of this surgery is to reduce the amount of food that can be eaten at one time, but there is no intervention in the natural flow of the digestive system to reduce absorption.

- Gastric Balloon

Intragastric balloon or stomach balloon has been used as a common and safe option in recent years as a non-surgical treatment method for people whose body mass index is outside the surgical margins.

- Gastric Bypass

Gastric bypass procedures are a group of similar surgeries used to treat morbid obesity, which results from excessive accumulation of excess weight in the body in the form of fat tissue and causes serious health problems.

In a gastric bypass, the stomach is first divided into a small upper section and a larger lower section called the “remnant”. Then, the connections of both pouches with the small intestine are rearranged.

- Duedonal Switch (SADI-S)

Duodenal switch surgery, also known as the duodenal switch with biliopancreatic diversion, is a long-term surgery. SADI-S is a more up-to-date and safer modification of this highly effective surgery.

SADI-S surgery is one of the surgeries that have both restrictive and absorption-reducing effects. This method, also called loop duodenal switch surgery, is a highly effective surgery for both weight loss and solving metabolic problems, especially diabetes, with its restrictive and severe absorption-reducing effects.

Metabolic Surgery (Type 2 Diabetes Surgery)

What is Metabolic Surgery (Type 2 Diabetes Surgery) and who is a suitable candidate for the surgery?

Diabetes (diabetes) disease is an important health problem that results mainly from unbalanced nutrition, sedentary lifestyle, and genetic factors and causes many other diseases such as impaired vascular structure, blindness, kidney failure, leg amputation, hypertension, and heart diseases.

There are two types of diabetes, Type 1 and Type 2. Type 1 diabetes is usually genetic and has congenital symptoms. In patients with Type 1 Diabetes, the pancreas cannot produce insulin and it must be taken from outside. In patients with type 2 diabetes, the pancreas cannot produce enough insulin for many reasons, and insulin production gradually decreases over time, and its secretion becomes unstable. That’s why blood sugar starts to rise and damage the vessels and other organs.

Although there are many drugs taken orally for high blood sugar levels, the results may be insufficient in some patients even if it is tried to be treated with external insulin injection. This is why metabolic surgery performed in the small intestine in Type 2 Diabetes patients enables the patient to use his/her own insulin.

Frequently Asked Questions

“Obesity Surgery” or “Bariatric Surgery” is a surgical intervention in the digestive system in order to help people to lose weight who are determined to be obese by measuring their body mass index or body fat ratio.

All surgical procedures performed today carry certain risks. Obesity surgery also includes similar risks. Obesity surgery is performed safely if the candidate is followed up by an experienced surgeon after being prepared for the surgery in detail. As a result, the risks that untreated obesity brings to your life cannot be ignored.

Obesity is an important risk factor for pregnancy complications and for the increase in fetal and neonatal morbidity. In addition, obesity is among the most important causes of infertility. You can get pregnant 1 year after surgery by consulting your doctor.

Bariatric surgery is most beneficial in obese patients with type 2 diabetes. Obesity surgery is especially recommended by international guidelines for patients in this group.

After the surgery, the nutrition program given by your doctor should be followed. High calorie, spicy, fatty foods, acidic, and carbonated drinks should not be consumed.

After the surgery, patients should follow the nutrition program. If they do not, they may experience weight gain problems depending on the type of surgery. This risk is between 5-10% after 3 years, but they usually never reach their pre-surgical weight.

It is possible to lose 10-20% of the weight in the first 3 months with a diet and exercise program after surgery. In the next 6 months, 30-35% of the weight is lost. The target weight is reached in the remaining months.

The exercise program given after the surgery is vital to prevent sagging. However, sagging may occur depending on the person’s body type, weight-intensive area, skin type, and age. If it becomes uncomfortable, plastic surgery procedures can be performed 1 year after the weight becomes stable.

Since obesity negatively affects the hormone balance of the body, you will have a healthier sex life after surgery.

Hair loss may occur in some people after surgery. The reason for this is hormonal changes in the body. Lost hair can come back and you can use additional vitamins containing B vitamin, Zinc, CO-enzyme Q in this process under the supervision of a doctor.

All obese patients between the ages of 18 and 70 who do not have any obstacle to surgery can be operated. Over the age of 70 should be evaluated separately, and obese patients under the age of 18 can undergo surgery with parental consent.

We can say that sleep apnea, which is usually caused by sagging and deformation caused by being overweight, passes after surgery in many patients.

The general procedure is to start work after 3 weeks. If you have desk jobs such as home office, you can start earlier by consulting your doctor.
