Bariatric surgery (RYGB, Sleeve Gastrectomy) provides superior and more sustained weight loss (25-35%) and metabolic remission compared to pharmacotherapy, but carries higher surgical risks and potential for long-term complications.
Bariatric surgery (like gastric bypass or sleeve gastrectomy) is the most effective treatment for severe obesity, typically resulting in 25-35% weight loss. It offers significant improvements in diabetes and hypertension. However, it is invasive, carries surgical risks, and requires lifelong nutritional monitoring. It is generally recommended for those with BMI ≥ 40 or ≥ 35 with comorbidities who have not succeeded with other methods.
Bariatric surgery remains the most effective long - term treatment for severe obesity... Roux – en - Y gastric bypass (RYGB) results in greater weight loss compared to sleeve gastrectomy (SG), with approximately 65.7% versus 57.3% weight loss at 5 years... Bariatric surgery tends to produce more consistent and durable results, particularly in individuals with BMI ≥40 kg/m²

- 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
