Endoscopic Sleeve
Endoscopic sleeve gastroplasty instead involves suturing the stomach to create changes in shape. Because of this, recovery time is greatly reduced, and the procedure is completely reversible and can be easily revised.

Gastric Bypass
This procedure affects the release of certain hormones associated with hunger. This creates a feeling of satiety after consumption of a smaller amount of food. This feeling is also present for a longer time.

Mini bypass
A mini-gastric bypass is a weight-loss procedure that involves making surgical changes to the stomach in order to reduce the release of hunger hormones.

Revision Weight Loss Surgery
Revision weight-loss surgery is a corrective procedure performed to address problems caused by a previous bariatric procedure. These problems may include digestive issues such as acid reflux.
