It is a type of bariatric surgery that consists of two components: first, a small gastric pouch is created by removing a portion of the stomach, similar to sleeve gastrectomy when performed with duodenal switch, or gastric bypass when performed without, and the first portion of the small intestine is separated from the stomach; then, a portion of the small intestine is connected to the outlet of the newly created stomach so that when the patient eats, the food passes through the sleeve pouch and reaches the last portion of the small intestine.

​

How does it work?

​

The smaller gastric pouch allows patients to ingest less food. The food stream bypasses approximately 75% of the small intestine, significantly decreasing the absorption of calories and nutrients, so patients must take vitamin and mineral supplements after surgery. It also affects gut hormones, reducing hunger, increasing satiety, and improving blood glucose control. It is considered the most effective #MetabolicSurgery for the treatment of type 2 diabetes.

​

Advantages

​

• Greater weight loss than other procedures. Among the best results for improving obesity.

• Allows patients to eat near-normal meals.

• Considerably reduces fat absorption.

• Affects bowel hormones to cause less hunger and more fullness after eating.

• It is the most effective procedure for treatment of type 2 diabetes.

 

What to expect?

 

• It is associated with some of the best metabolic effects and long-term weight loss of all bariatric procedures.

• The average excess weight loss remains above 75% after 10 years.

• Significant impact on comorbidities associated with obesity, including type 2 diabetes, hypertension, sleep apnea, and dyslipidemia.
