Gastric Sleeve

What Is a Gastric Sleeve?

A gastric sleeve, also known as a sleeve gastrectomy, is a surgical weight-loss procedure that permanently reduces the size of the stomach. During the operation, a surgeon removes approximately 75% to 80% of the stomach, leaving behind a narrow, tube-like "sleeve" about the size and shape of a banana. This procedure is typically performed using minimally invasive laparoscopic techniques, which involve small incisions and a faster recovery time compared to traditional open surgery.

How It Works

• Volume Restriction: By significantly reducing the stomach's capacity, the procedure limits the amount of food a person can consume in one sitting, leading to a faster feeling of fullness.
• Hormonal Regulation: The portion of the stomach that is removed is responsible for producing most of the body's ghrelin, often called the "hunger hormone." Reducing ghrelin levels helps decrease appetite and cravings.
• Metabolic Impact: The surgery triggers changes in gut hormones that can improve blood sugar regulation and help resolve metabolic conditions like type 2 diabetes.

Who It's For

• Adults with a Body Mass Index (BMI) of 40 or higher.
• Individuals with a BMI of 35 to 39.9 who also suffer from obesity-related health conditions such as type 2 diabetes, severe sleep apnea, or high blood pressure.
• Patients who have been unable to achieve or maintain weight loss through medically supervised diet and exercise programs.
• Individuals committed to making permanent, lifelong changes to their eating habits and lifestyle.

Benefits

• Effective Weight Loss: Most patients lose between 60% and 70% of their excess body weight within the first 12 to 18 months following surgery.
• Health Improvement: The procedure often leads to the remission or significant improvement of obesity-related diseases, including hypertension and fatty liver disease.
• No Intestinal Rerouting: Unlike gastric bypass, the sleeve gastrectomy does not alter the small intestine, which reduces the risk of certain nutritional malabsorption issues and "dumping syndrome."
• No Foreign Objects: There are no plastic bands or devices left in the body, eliminating the risk of slippage or erosion associated with gastric banding.

Limitations & Risks

• Irreversibility: Because a large portion of the stomach is surgically removed, the procedure is permanent and cannot be reversed.
• Surgical Complications: Potential risks include staple-line leaks, internal bleeding, infection, or blood clots (deep vein thrombosis).
• Acid Reflux: Some patients may develop new or worsening gastroesophageal reflux disease (GERD) after the procedure.
• Nutritional Maintenance: Patients must take daily vitamin and mineral supplements for life to prevent deficiencies, as the total volume of food intake is greatly reduced.

Questions to Ask Your Clinic

• How many sleeve gastrectomy procedures has the surgeon performed in the last year?
• What is the clinic's specific rate of complications, such as staple-line leaks?
• What kind of long-term nutritional and psychological support is included in the treatment package?
• What pre-operative tests (such as an endoscopy or cardiac clearance) are required before the surgery?
• How does the clinic manage post-operative emergencies for international patients?
