A gastric sleeve operation, or sleeve gastrectomy, is an advanced weight-loss (bariatric) surgery that helps people with obesity achieve significant and sustained weight reduction.
It involves reducing the stomach’s size to limit food intake and control hunger.
Performed by Dr. Nidhi Khandelwal, an expert GI and Laparoscopic Surgeon, this minimally invasive procedure provides lasting weight loss and improvement in obesity-related health problems.
How the Surgery Works
During the procedure, about 75–80 percent of the stomach is removed, leaving a narrow, sleeve-shaped pouch.
This smaller stomach:
- Limits food intake
- Decreases hunger hormone (ghrelin) levels
- Helps maintain long-term weight loss
The surgery is performed laparoscopically, using small keyhole incisions, leading to faster recovery and minimal pain.
Who Is a Candidate for Gastric Sleeve Surgery
- BMI ≥ 40 (Severe Obesity)
- BMI ≥ 35 with conditions like diabetes, sleep apnea, hypertension
- Failed weight loss through diet and exercise
- Medically fit for anaesthesia and surgery

Average surgery time: 1–2 hours.
Hospital stay: 1–2 days
Recovery Timeline
