What is Sleeve Gastrectomy with Proximal Jejunal Bypass in bangkok, thailand (SG PJB)

Sleeve Gastrectomy with Proximal Jejunal Bypass (SG PJB) is a type of weight loss surgery. The procedure involves removing a large portion of the stomach, leaving a small “sleeve” or tube-like stomach in its place. The remaining stomach is about the size of a banana. This reduces the amount of food that can be eaten and decreases the amount of hunger-causing hormones produced by the stomach.

The Proximal Jejunal Bypass (PJB) component of the surgery is an additional step that is done by connecting the upper part of the small intestine (the jejunum) to the newly created small stomach. This helps to decrease the absorption of calories and nutrients from food, which leads to further weight loss.

SG PJB is considered a complex surgery and it’s usually recommended for patients who are morbidly obese and have not been able to achieve weight loss through other methods.

The surgery is performed under general anesthesia and usually takes several hours. It’s important to note that, like any weight loss surgery, SG PJB carries certain risks and patients must follow a strict post-surgery diet and lifestyle regimen to ensure the best outcome.
