Bariatric surgery, specifically Roux-en-Y gastric bypass (RYGB), is a highly effective treatment for severe obesity, providing rapid and durable weight loss, though it carries risks of adverse events and nutritional deficiencies.
For individuals with severe obesity (BMI >40 or >35 with comorbidities), bariatric surgery like RYGB is a highly effective, durable treatment. It is not a cosmetic procedure but a medical intervention for severe disease. Patients must be prepared for lifelong nutritional monitoring to prevent deficiencies.

Bariatric surgery is an effective treatment for severe obesity (body mass index > 40, or >35 kg/m2 with comorbidities) that provides rapid and durable improvements in obesity but may increase the risk of postoperative adverse events and postoperative complications... Roux-en-Y gastric bypass (RYGB)... have become the three most commonly used procedures for the treatment of morbid obesity worldwide.
Why this rating
Bariatric surgery is well-established in clinical literature; the paper summarizes this consensus.

More from this paper
- Time-restricted eating (TRE) is currently the most prevalent and hottest research topic for obesity intervention, showing equivalent weight loss to continuous energy restriction while offering better long-term adherence.Moderate
- Probiotic supplementation has a regulatory effect on weight and BMI, with greater weight loss magnitude observed in populations with longer treatment durations.Moderate
