Bariatric Surgery

Weight loss surgery that changes the digestive system to help people with severe obesity achieve lasting results.

Bariatric surgery, also called weight loss surgery, changes your digestive system to help you lose weight when diet and exercise have not worked. Common types include gastric bypass and sleeve gastrectomy. It is usually recommended for people with severe obesity or obesity-related health conditions.

Bariatric surgery encompasses restrictive, malabsorptive, and combined procedures that alter gastrointestinal anatomy to achieve significant and sustained weight loss. Indications include BMI ≥40 kg/m² or BMI ≥35 kg/m² with obesity-related comorbidities. Mechanisms include reduced gastric capacity, altered gut hormone secretion (increased GLP-1, PYY; decreased ghrelin), and bile acid signalling changes.
