Gastric Bypass

Gastric bypass, or Roux-en-Y gastric bypass, is a type of weight-loss surgery that involves creating a small pouch from the stomach and connecting the newly created pouch directly to the small intestine. This procedure is done to bypass a significant part of the stomach and the first section of the small intestine, reducing the amount of food intake and the absorption of nutrients, leading to weight loss.

Success Rate: The success rate of gastric bypass surgery is high, with about 80% of patients achieving and maintaining significant weight loss.
Recovery: The hospital stay after gastric bypass is usually 2 to 3 days. Full recovery, including the ability to resume normal physical activities, may take 2 to 3 weeks.

Gastric Sleeve

Gastric sleeve surgery, also known as sleeve gastrectomy, is a type of bariatric surgery that involves the removal of about 80% of the stomach, leaving a tubular 'sleeve' about the size and shape of a banana. This procedure is performed laparoscopically and is irreversible. It works by reducing the size of the stomach and thereby limiting the amount of food that can be eaten at one time, while also reducing the production of the hunger hormone ghrelin.

Success Rate: Around 60% to 70% of excess weight loss can be expected within one to two years following the procedure, with high success rates in maintaining significant weight loss over 5 years.
Recovery: Most patients can expect to stay in the hospital for 2 to 3 days following the surgery. Full recovery, including the resumption of normal activities, can usually be expected within 3 to 5 weeks.

Duodenal Switch

The duodenal switch, also known as biliopancreatic diversion with duodenal switch (BPD/DS), is a type of weight loss surgery that involves two main steps. The first is a sleeve gastrectomy, in which a large part of the stomach is removed to restrict food intake. The second is a rerouting of the intestines to reduce calorie absorption. This dual approach makes it one of the most effective bariatric surgeries for weight loss and resolution of comorbidities.

Success Rate: Most patients lose 70-80% of their excess weight within two years and maintain a significant weight loss of 60-70% at 10 years.
Recovery: Patients usually stay in the hospital for 2 to 3 days after the surgery. A full recovery usually takes 3 to 6 weeks, and adjustments to the new eating patterns may take several months.

Gastric Balloon

The gastric balloon is a non-surgical, minimally invasive weight loss procedure. A soft silicone balloon is inserted into the stomach and filled with a saline solution, creating a sense of fullness, and thus, reducing food intake. It is usually performed on an outpatient basis and is temporary, with the balloon typically removed after six months.
