What is Gastric Sleeve?

Gastric sleeve surgery is a restrictive bariatric procedure.

During the operation:

• Approximately 70–80% of the stomach is removed
• The remaining stomach is shaped into a narrow tube (“sleeve”)
• The digestive tract is not bypassed

This leads to:

• Reduced stomach capacity
• Earlier satiety
• Decreased hunger-related hormone production (ghrelin)

Unlike gastric bypass, the intestines are not rerouted.

Who Is a Candidate for Gastric Sleeve?

Sleeve gastrectomy in Istanbul may be considered for individuals who:

• Have a BMI over 40
• Have a BMI over 35 with obesity-related medical conditions
• Have attempted structured weight loss programs without long-term success
• Are medically evaluated as suitable for bariatric surgery

Comprehensive internal medicine and metabolic assessments are required before approval.

How Is Sleeve Gastrectomy Performed?

The procedure is performed under general anesthesia using laparoscopic techniques.

Surgical overview:

• Several small incisions are made in the abdomen
• A laparoscope is inserted
• A large portion of the stomach is removed
• The remaining stomach is sealed using surgical staplers

The operation typically lasts 1.5–2 hours.

The removed portion of the stomach is permanently excised.

Recovery & Aftercare

Sleeve-Shaped Stomach Reduction

Gastric sleeve surgery removes a large portion of the stomach, leaving a narrow tube-shaped stomach that limits food intake.

Minimally Invasive Procedure

The surgery is typically performed using laparoscopic techniques with small incisions and specialized surgical instruments.

Guided Post-Surgery Nutrition

Patients follow a structured diet plan that gradually progresses from liquids to soft foods before returning to regular meals.

Sustainable Weight Management

Long-term success depends on adopting healthier eating habits, maintaining regular physical activity, and ongoing medical guidance.

Safety and Long-Term Outcomes

Expected Weight Loss and Results

Sleeve gastrectomy is considered an effective bariatric intervention for significant weight reduction.

Many patients experience:

• Substantial excess weight loss within the first 12–18 months
• Improvement in type 2 diabetes
• Reduced blood pressure
• Improvement in sleep apnea

However, surgery is a medical tool — long-term results depend on:

• Nutritional discipline
• Behavioral adaptation
• Physical activity
• Structured follow-up

Risks and Considerations

As with any major surgery, risks exist, including:

• Bleeding
• Staple line leaks
• Infection
• Acid reflux
• Nutritional deficiencies

Long-term follow-up is essential.

Unlike gastric bypass, malabsorption is less common, but vitamin monitoring remains necessary.
