Transit Bipartition surgery is a surgical intervention used in the treatment of diabetes. This surgery promotes weight loss by cutting a portion of the small intestine and limiting nutrient intake. During the procedure, the upper part of the small intestine is sealed off, while the lower part is left active. This creates a narrowing in the path of food through the intestines, reducing nutrient absorption. Transit Bipartition surgery restricts food intake both mechanically and by reducing absorption, thus facilitating weight loss. A careful dietary regimen and lifestyle changes are necessary post-surgery. Following an appropriate follow-up program guided by a specialist is crucial for post-operative success. However, like any surgical procedure, Transit Bipartition carries its own risks and can lead to surgical complications.
