Sleeve Gastrectomy
Sleeve Gastrectomy is a weight loss surgery that removes around 80% of the stomach, leaving a smaller, tube-like sleeve. This helps reduce food intake and influences hunger hormones for long-term results.
What is Sleeve Gastrectomy?
Sleeve Gastrectomy, also known as Gastric Sleeve Surgery, is a type of bariatric surgery that involves removing approximately 75-80% of the stomach, leaving a sleeve-shaped stomach about the size of a banana. This reduction in stomach size not only limits the amount of food one can eat but also significantly decreases the production of the hunger hormone ghrelin, reducing appetite and supporting long-term weight loss.
What are the Benefits of Sleeve Gastrectomy?
Effective Weight Loss: Patients typically lose 50-70% of their excess weight within the first year following surgery.
Improvement of Obesity-Related Conditions: Sleeve Gastrectomy can lead to improvements or resolution of conditions such as type 2 diabetes, hypertension, sleep apnea, and joint pain.
Reduced Hunger: By removing the portion of the stomach that produces ghrelin, the surgery helps reduce hunger, making it easier to maintain a healthier diet.
Minimal Malabsorption: Unlike Gastric Bypass, Sleeve Gastrectomy does not alter the intestines, reducing the risk of nutritional deficiencies and making it a simpler procedure with fewer complications.
When to Consider Sleeve Gastrectomy?
Sleeve Gastrectomy may be a suitable option for individuals who:
Have a BMI of 40 or higher, or have a BMI of 35 or higher with obesity-related health conditions such as type 2 diabetes, heart disease, or severe sleep apnea.
Have been unsuccessful in achieving or maintaining weight loss through non-surgical methods such as diet, exercise, and medication.
Are committed to making the necessary lifestyle changes, including dietary adjustments and regular exercise, to ensure the success of the procedure.
What to Expect During the Procedure
Sleeve Gastrectomy is typically performed laparoscopically, using small incisions and specialised instruments guided by a camera. The surgery generally takes 1-2 hours, and most patients stay in the hospital for 1-2 days. Recovery times vary, but many patients are able to resume normal activities within 2-4 weeks. Post-surgery, patients will follow a structured diet and gradually reintroduce solid foods as their body heals.
What are the Risks of Sleeve Gastrectomy?
While Sleeve Gastrectomy is generally safe, it does carry potential risks, including:
Surgical Complications: As with any surgery, risks include infection, bleeding, or adverse reactions to anaesthesia.
Gastroesophageal Reflux Disease (GERD): Some patients may experience or have worsening acid reflux symptoms after the surgery.
Staple Line Leaks: There is a small risk of leakage along the staple line where the stomach was divided, which can lead to serious complications.
Nutritional Deficiencies: Although less common than with other bariatric procedures, deficiencies in vitamins and minerals can occur, requiring lifelong supplementation.
