Gastric Sleeve Surgery in Türkiye

What gastric sleeve is

Gastric sleeve, medically known as sleeve gastrectomy, is a bariatric operation in which a large part of the stomach is removed, leaving a narrow, tube-shaped stomach. The smaller stomach holds far less food, and changes in gut hormones, including those linked to hunger, may also contribute to the effect.

It is a major surgical operation and is considered a tool within a long-term programme of nutrition, activity and follow-up, not a quick fix.

How the technique works

The operation is usually carried out laparoscopically, through several small incisions in the abdomen, under general anaesthesia. The surgeon divides the stomach lengthwise with a surgical stapler and removes the outer, larger portion. The remaining stomach is often described as a sleeve or banana shape.

The surgeon also checks the staple line for leaks and bleeding. Because the intestines are not rerouted, food passes through the digestive tract in the usual order, which is one reason the procedure is often chosen.

• General anaesthesia and laparoscopic access
• Division and removal of most of the stomach
• Checking the staple line
• Closure of the small incisions

Who is a suitable candidate

Guidelines in many countries consider bariatric surgery for adults with a body mass index of about 40 or above, or around 35 or above with obesity-related conditions such as type 2 diabetes or sleep apnoea. Thresholds vary, and in some cases lower values are considered.

A full assessment typically includes blood tests, an evaluation of heart and lung fitness, and often an endoscopy. Psychological and nutritional review is also an important part of preparation.

• Documented, long-standing difficulty losing weight by other means
• Willingness to follow dietary stages and take supplements
• Absence of conditions that make surgery unsafe
• Severe, uncontrolled reflux needing specialist discussion beforehand

Procedure day, recovery and results timeline

You usually stay in hospital for around two to three nights. Fluids are started within a day or so, followed by staged progression from liquids to purées, soft foods and then regular food over several weeks. Walking is encouraged early to reduce the risk of clots.

Weight loss is often most rapid in the first six months and continues more slowly up to about 12 to 18 months. The amount differs widely between people. Regular check-ups, blood tests and vitamin supplements are typically required over the long term.

Risks and important considerations

Risks include bleeding, infection, staple line leaks, blood clots, narrowing of the stomach and reflux, which can develop or worsen. Nutritional deficiencies are possible without supplements. Some people regain weight over time, and loose skin is common after major weight loss.

The operation is generally not reversible. Make sure you understand the follow-up plan, how complications are managed and who you would contact after returning home before you decide.

Results and recovery times vary from person to person. Every treatment starts with a medical evaluation by a licensed specialist.
