Mini-Gastric Bypass (MGB) is a surgical procedure used for the treatment of obesity. In this method, stomach reduction and rerouting of the intestines are performed. MGB is a less invasive method compared to other bariatric surgery procedures.

In MGB surgery, the surgeon makes the stomach a smaller bag. A small incision is made in the stomach and a clip (Clamp) is placed to separate the stomach from the lower part of the stomach and to make the upper part a smaller bag. Next, the outlet of this bag is connected to a part of the intestines. In this way, fewer nutrients are absorbed in the intestine and fewer calories are taken.

MGB surgery provides advantages such as being less invasive, having shorter operation time, and having faster recovery time compared to other bariatric surgery procedures. The weight loss results of MGB are as effective as other methods and can help treat obesity-related diseases after weight loss.

However, before any surgical procedure, the risks and benefits should be carefully evaluated and consulted with a physician. The MGB procedure, like other bariatric surgery procedures, involves infection, bleeding, intestinal problems, and other surgical risks. Some side effects may be associated with MGB, including reflux, nutritional deficiencies, and vitamin and mineral deficiencies.
