Gastric sleeve removes approximately 75–80% of the stomach. Gastric bypass additionally reroutes the small intestine for a stronger malabsorptive effect and superior metabolic outcomes (especially for Type 2 diabetes). The right choice depends on your health profile and will be discussed during consultation.

Dr. Katar's Painless Gastric Sleeve protocol incorporates paragastric block anaesthesia, a no-drain no-NGT approach (where clinically appropriate), and an early mobilisation programme — significantly reducing post-operative pain and nausea compared to conventional sleeve gastrectomy.

The general guideline is BMI ≥ 40, or ≥ 35 with at least one obesity-related comorbidity. Some patients with BMI 30–35 and poorly controlled Type 2 diabetes may be considered for metabolic surgery. Individual assessment is required.
