Compare Surgical Options


The four most frequently-performed metabolic and bariatric surgeries each take a different approach to surgical weight loss, and the correct one for you will be based on your unique anatomy and metabolism, medical history, and weight loss goals. Understanding the differences between the surgical options can be both difficult and frustrating if you do not have access to up-to-date, accurate information. Dr. Wiljon Beltre and his experienced team of weight loss experts at The Center for Metabolic and Obesity Surgery believe in the critical importance of enabling patients to make well-informed, educated decisions, and will work closely with you to help you decide which option is best suited to give you the self-confidence and strength to finally realize your ideal size, shape, and physique.


Gastric bypass: One of most aggressive options, gastric bypass is both invasive and technically difficult, but enables very rapid weight loss and extraordinarily quick resolution of some obesity-related health concerns like type 2 diabetes. It requires a life-time commitment to strict dietary changes and altered eating habits, as well as regular vitamin supplements.

Sleeve Gastrectomy: Sleeve gastrectomy offers similar, but slightly less aggressive weight loss and health-related results as the more invasive gastric bypass but also entails less surgical risk. Long-term risk of vitamin and nutritional deficiencies and “dumping syndrome” are lower, and long-term dietary requirements are less strict.

Gastric Band: Gastric banding is the least invasive surgical procedure, but results in only moderate weight loss and does not appear to correct obesity-related health concerns except as related to weight loss. Vitamin and nutritional deficiencies are extremely uncommon, but long-term dietary requirements are strict and frequent, regular follow-up visits for band readjustment are required.

Biliopancreatic Diversion (BPD) with Duodenum Switch (BPD/DS): BPD/DS is the most aggressive and technically demanding form of metabolic surgery, but results in the most significant, long-term weight loss and immediate resolution of type 2 diabetes and other metabolic health problems. Food intake is less limited than with other procedures, but strict adherence to dietary changes and vitamin supplements is required. Foul-smelling gas, bloating, and frequent, pasty bowel movements are life-long side effects, and the risk of ulcers and heartburn is higher than with other surgeries.
