Gastric Sleeve in Turkey (Sleeve Gastrectomy)

Gastric sleeve surgery, also known as sleeve gastrectomy, is a weight-loss procedure that reduces the size of the stomach. During the operation, approximately 70–80% of the stomach is removed, leaving a narrow, tube-shaped stomach.

The smaller stomach limits the amount of food a person can eat at one time and helps them feel full sooner. Gastric sleeve surgery also reduces the production of ghrelin, a hormone that plays an important role in appetite and hunger. As a result, many patients experience reduced hunger and improved portion control after surgery.

The procedure is usually performed laparoscopically through several small incisions in the abdomen. This minimally invasive approach can result in smaller scars and generally supports a faster recovery than open surgery.

The procedure typically takes approximately 1–2 hours under general anesthesia. Most patients stay in the hospital for around 1–2 nights, although the exact duration depends on their health and recovery.

Benefits of Gastric Sleeve Surgery

Gastric sleeve surgery can help suitable patients achieve significant weight loss and improve obesity-related health problems. However, results vary between individuals and depend on factors such as starting weight, eating habits, physical activity, and adherence to long-term lifestyle recommendations.

Significant Weight Loss

Many patients lose a substantial proportion of their excess weight during the first year following gastric sleeve surgery. The amount and rate of weight loss vary from person to person, and maintaining the results requires long-term changes to diet and lifestyle.

Reduced Hunger and Portion Sizes

The smaller stomach capacity helps patients feel full after eating smaller portions. Because much of the stomach is removed during the procedure, ghrelin production is also reduced, which may contribute to lower appetite after surgery.

Improvements in Obesity-Related Health Conditions

Significant weight loss may help improve or manage conditions associated with obesity, including type 2 diabetes, high blood pressure, obstructive sleep apnea, and certain joint problems. The potential health benefits depend on the individual's overall health and response to weight loss.

Preparing for Gastric Sleeve Surgery

Before gastric sleeve surgery, patients undergo a medical assessment to determine whether the procedure is appropriate for them and to identify any factors that could affect surgery or recovery.

The bariatric team may request blood tests, imaging, nutritional assessments, and other examinations depending on the patient's medical history. Patients may also receive specific instructions to follow in the days or weeks before surgery.

Preparation may include:

• Following a pre-operative diet recommended by the bariatric team
• Avoiding smoking and limiting or avoiding alcohol
• Reviewing current medications with the medical team
• Completing all requested examinations and tests
• Arranging support for the first days after returning home
• Understanding the dietary and lifestyle changes required after surgery

Following the surgeon's instructions before the procedure can help patients prepare for surgery and recovery.

Gastric Sleeve Surgery Risks and Precautions

Although gastric sleeve surgery is commonly performed and is generally considered safe when patients are appropriately selected, it is still a major surgical procedure and carries potential risks.

Possible complications include:

• Bleeding
• Infection
• Blood clots
• Anesthesia-related complications
• Leakage from the stomach staple line

Longer-term problems can also occur, including nutritional deficiencies, acid reflux, or difficulty tolerating certain foods. The risk of complications varies depending on factors such as the patient's general health, surgical technique, and adherence to post-operative recommendations.

In some cases, patients who experience complications, insufficient weight loss, or significant weight regain after bariatric surgery may require revisional bariatric surgery to address the issue and achieve better long-term results.

Patients should discuss the potential benefits, risks, expected outcomes, and alternative treatment options with their surgeon before deciding to undergo gastric sleeve surgery. 

Recovery and Aftercare

Recovery after gastric sleeve surgery takes place gradually. Patients generally remain in the hospital for 1–2 nights so their condition can be monitored after the procedure.

Walking is usually encouraged soon after surgery to promote circulation and reduce the risks associated with prolonged inactivity. However, strenuous exercise and heavy lifting should be avoided until the surgeon confirms that these activities are safe.

Diet is an important part of recovery. Patients usually begin with liquids before gradually progressing to pureed foods, soft foods, and eventually solid foods. The timing of each stage varies according to the patient's recovery and the recommendations of the surgeon and dietitian.

Long-term follow-up is essential after gastric sleeve surgery. Regular medical assessments and nutritional counseling can help patients maintain adequate nutrition, adapt to smaller portions, and develop sustainable eating habits.
