Bariatric surgery (gastric banding, bypass, sleeve gastrectomy) results in large weight loss, induces remission of type-2 diabetes and hypertension, and increases life expectancy.
For severe obesity where other methods fail, bariatric surgery is a highly effective option that can lead to significant weight loss and remission of conditions like diabetes and high blood pressure. It can also increase life expectancy and be cost-effective over the long term, provided resources are available.
GoodSupportsHIGH confidence
Surgery results in large weight loss and induces improvement or even remission of obesity-related conditions such as hypertension and type-2 diabetes, and increases life expectancy.

- GLP-1 agonist semaglutide produces significant weight loss (12.7%) and improves cardiometabolic risk in adults with obesity, with transient mild-to-moderate nausea and diarrhea as primary side effects.Good
- A 5-10% weight loss in adults is often sufficient to obtain substantial health benefits from decreasing obesity-related comorbidities, challenging the goal of maximum weight loss in the shortest time.Moderate

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
