Gastric sleeve surgery in Türkiye is a surgical treatment that may be considered for people whose excess weight makes daily life difficult and who experience obesity-related health problems. For patients seeking to move more comfortably and lead a healthier life, the first step is to determine whether they are suitable for surgery. People planning treatment in İzmir through Healthylife Clinic can discuss their health status and treatment options with General Surgeon Dr. Serkan Tüğen.

What Is Gastric Sleeve Surgery And How Is It Performed?

During gastric sleeve surgery, approximately 80% of the stomach is removed to create a narrower, tube-shaped stomach. The procedure is usually performed laparoscopically under general anaesthesia. The smaller stomach makes it easier to feel full after eating less, while hormonal changes affecting appetite may also support weight loss. The procedure is irreversible.

How Much Do You Need To Weigh To Have Gastric Sleeve Surgery?

There is no single weight requirement; eligibility is assessed using the body mass index (BMI), which is calculated from height and weight.

• Bariatric surgery may be considered for people with a BMI of 35 or above.

• Surgery may be considered for selected patients with a BMI between 30 and 34.9, particularly in the presence of metabolic disease or when non-surgical treatments have not produced lasting results.

Meeting these criteria does not automatically mean that you are suitable for gastric sleeve surgery. The choice of procedure depends on your overall health and a detailed medical assessment.

How Long Does Gastric Sleeve Surgery Take And How Many Days Do You Stay In Hospital?

The operation usually takes 1–2 hours. The hospital stay is generally 1–2 nights, although it may be longer depending on accompanying medical conditions and recovery. The decision to discharge a patient is made individually.

How Much Weight Can You Lose After Gastric Sleeve Surgery?

The amount of weight lost varies depending on your starting weight, diet, physical activity and follow-up care. Approximately 60% or more of excess weight may be lost over two years; this percentage does not refer to total body weight. Results are not guaranteed, and weight regain is possible.

How Should You Eat After Surgery?

Following the programme prepared by your care team, your diet progresses gradually from liquids to puréed foods and then to solid foods. Adequate fluid and protein intake, recommended supplements and regular blood tests are part of long-term follow-up care.
