Understanding Gastric Sleeve Surgery
Date : 2025-05-20
Gastric sleeve surgery, also known as sleeve gastrectomy, is one of the most effective bariatric procedures for individuals struggling with obesity. This minimally invasive surgery not only helps with significant weight loss but also improves overall health by reducing obesity-related conditions such as diabetes, hypertension, and sleep apnea.
How Does Gastric Sleeve Surgery Work?
During the procedure, about 75–80% of the stomach is removed, leaving a tube-like structure or “sleeve.” This smaller stomach size helps control portion intake and reduces hunger by lowering the production of ghrelin, the hormone responsible for appetite.
Key Benefits of Gastric Sleeve Surgery
✔ Sustainable Weight Loss — Patients typically lose 50–70% of their excess weight within the first 1–2 years.
✔ Health Improvement — Conditions like diabetes, high blood pressure, and sleep apnea often show significant improvement or remission.
✔ Minimally Invasive — The laparoscopic approach ensures faster recovery and minimal scarring compared to open surgery.
Who is an Ideal Candidate for a gastric sleeve?
✅ Individuals with a BMI of 35+ or a BMI of 30+ with obesity-related health conditions.
✅ Those who have tried and failed with diet and exercise alone.
✅ People committed to long-term lifestyle changes for sustainable results.
Recovery and Aftercare
The hospital stay is usually 1–2 days, and full recovery takes 4–6 weeks. Patients must follow a specific post-surgery diet, transitioning from liquids to solid foods gradually. Regular dietitian consultations and an active lifestyle ensure long-term success.
Gastric Sleeve vs. Other Bariatric Surgeries
- Gastric Sleeve: Restricts food intake and reduces hunger hormones without rerouting the intestines.
- Gastric Bypass: Involves creating a small stomach pouch and rerouting the intestines for additional calorie malabsorption.
- Lap Band Surgery: Uses an adjustable silicone band around the stomach but has a higher risk of complications.
