Obesity surgery is a surgical procedure performed when an individual’s body mass index exceeds a certain threshold, in order to support weight loss. It is typically considered when diet and exercise alone have not produced sufficient results. Obesity surgery includes techniques that either reduce the size of the stomach or limit the absorption of nutrients. It also helps manage obesity-related conditions such as type 2 diabetes, sleep apnea, and hypertension. Turkey stands out in the field of obesity surgery with its advanced medical infrastructure, experienced surgeons, and cost-effective treatment options for international patients.
What is Obesity Surgery?
Obesity surgery is a surgical intervention performed to help severely overweight individuals lose weight and reduce obesity-related health problems. These procedures work by reducing the size of the stomach and limiting nutrient absorption. When diet, exercise, or medication fail to produce sufficient results, obesity surgery becomes a treatment option. This intervention is not only for aesthetic purposes but also plays a key role in managing chronic conditions such as type 2 diabetes, sleep apnea, and hypertension.
Types of Obesity Surgery
Obesity surgery can be performed using different methods depending on the individual's health condition, body mass index, and associated diseases. The surgical technique is selected based on the goal of the procedure and whether it involves reducing the stomach size. The most suitable method is determined through a detailed evaluation between the doctor and the patient.
The main types of obesity surgery are as follows:
Sleeve Gastrectomy
In this procedure, a large portion of the stomach is removed, leaving behind a tube-shaped, smaller stomach. This method not only reduces stomach volume but also decreases the levels of hormones that stimulate appetite. It is known to provide effective weight loss and improve various obesity-related health conditions.
Gastric Bypass
The stomach is divided into a small pouch and connected to a specific part of the small intestine. This limits both food intake and nutrient absorption. It is particularly effective for patients with type 2 diabetes and often leads to significant metabolic improvements.
Mini Gastric Bypass
Similar to traditional gastric bypass, this method involves creating a smaller stomach pouch and rerouting part of the small intestine. However, it is technically simpler and can be performed in a shorter time. It is known for producing effective results with fewer surgical steps.
Duodenal Switch
This complex procedure combines sleeve gastrectomy with an intestinal bypass. It significantly reduces the absorption of calories and fats. It is typically reserved for patients with severe obesity, but it requires strict nutritional monitoring due to its intensive nature.
Who Is a Candidate for Obesity Surgery?
Obesity surgery may be considered when a person is 45–50 kilograms or more above their ideal weight. However, not all overweight individuals are suitable candidates; specific medical criteria must be met. A person may be considered a candidate for obesity surgery under the following conditions:
- Body Mass Index (BMI) of 40 or higher
- BMI between 35 and 39.9 along with obesity related health conditions (e.g., type 2 diabetes, sleep apnea, hypertension)
- Inability to achieve long-term weight loss through diet, exercise, or medication
- Being psychologically prepared for the surgical process
- Willingness and ability to adapt to necessary lifestyle changes after surgery
- Being between the ages of 18 and 65, with a general health status suitable for surgery
