Bariatric (weight loss) surgery is the most effective long-term treatment for morbid obesity and its complications, including
type 2 diabetes, hypertension, obstructive sleep apnoea, and severe joint disease. At Charak Hospital's dedicated
Minimal Access & Bariatric Surgery department, our experienced bariatric surgeons offer all major laparoscopic procedures with comprehensive pre-operative evaluation and lifelong post-operative support.
Bariatric Procedures We Offer
1. Laparoscopic Sleeve Gastrectomy (Gastric Sleeve)
75–80% of the stomach is removed laparoscopically, leaving a narrow tube. Reduces food intake and hunger hormone (ghrelin) production. No intestinal rerouting. Hospital stay: 2–3 days. Most popular bariatric procedure worldwide.
2. Laparoscopic Roux-en-Y Gastric Bypass (RYGB)
A small stomach pouch is created and connected directly to the small intestine, bypassing most of the stomach and first part of the intestine. Greatest weight loss and diabetes remission rates. Recommended for BMI >50 or severe diabetes.
3. Mini-Gastric Bypass (One Anastomosis Gastric Bypass)
A simplified bypass with a single connection point. Combines restriction and malabsorption. Excellent weight loss and diabetes outcomes with a shorter operative time than RYGB.
4. Revisional Bariatric Surgery
For patients who have had prior bariatric surgery with inadequate weight loss or complications. Our team evaluates each case individually for the most appropriate revision procedure.
