Jejunoileal bypass (JIB) is a type of weight loss surgery that involves rerouting a portion of the small intestine to bypass the upper part of the small intestine, where most food is absorbed.
During the JIB procedure, the surgeon divides the small intestine and connects the lower end of the small intestine (ileum) to the upper part of the small intestine (jejunum) at a point farther down the digestive tract. This rerouting of the intestine reduces the amount of food that can be absorbed, leading to weight loss.
JIB was first introduced in the 1950s and was one of the earliest forms of weight loss surgery. However, the procedure has largely been replaced by other, more effective and safer weight loss surgeries, such as gastric bypass and sleeve gastrectomy.
JIB is associated with a number of potential complications, including malabsorption of nutrients, diarrhea, and vitamin deficiencies. In addition, the long-term effectiveness of the procedure is unclear, and it has been largely replaced by other weight loss surgeries that are considered to be safer and more effective.
As with any weight loss surgery, it is important to discuss the potential risks and benefits of JIB with a qualified healthcare provider before making a decision. It is also important to follow a strict diet and exercise plan after surgery in order to achieve and maintain weight loss.
