Gastric bypass surgery involves creating a small pouch from the stomach and connecting it directly to the small intestine. It significantly reduces food intake and alters digestion, leading to substantial weight loss. This procedure is one of the most common forms of bariatric surgery and is highly effective for long-term weight reduction.

After undergoing Roux-en-Y gastric bypass surgery (RNY), the diet is critical for long-term success and recovery. Immediately after surgery, patients are required to follow a liquid diet to allow their stomachs to heal. Over time, they transition from liquids to soft foods, and eventually solid foods. This post-op diet is high in protein to support muscle retention and healing, low in fats and sugars, and carefully portioned to avoid stretching the stomach pouch. Lifelong dietary changes are necessary to avoid... +More

The lap band and sleeve gastrectomy are two different bariatric surgeries. The lap band is adjustable and reversible, involving the placement of a band around the upper stomach. The sleeve, on the other hand, is permanent and involves the removal of part of the stomach. Sleeve gastrectomy tends to offer more substantial long-term weight loss, but the lap band has fewer immediate risks.

Sleeve banding combines two bariatric procedures: the gastric sleeve and an adjustable gastric band. It is a less common technique used to enhance the weight-loss results of the sleeve by adding additional restriction through the band. However, complications from the band have made it less favorable in recent years.

The term bariatric refers to the branch of medicine focused on the prevention and treatment of obesity and related disorders. Bariatric procedures, such as gastric bypass or sleeve gastrectomy, are designed to help patients achieve significant, long-term weight loss when other methods like diet and exercise have failed.
