Classic gastric bypass, also known as Roux-en-Y Gastric Bypass, is one of the most common and effective bariatric surgeries. This procedure reduces stomach size and alters the digestive pathway to limit calorie absorption. It is known for rapid and sustained weight loss, along with significant improvement in obesity-related conditions such as type 2 diabetes and high blood pressure.
The surgery is performed under general anesthesia, where the surgeon makes small incisions in the abdomen using a laparoscope.
A small pouch is created in the upper part of the stomach, separate from the rest of the stomach, reducing the amount of food that can be consumed.
The small intestine is then cut, and the lower part is connected directly to the small stomach pouch, bypassing the larger part of the stomach and the first part of the small intestine.
The upper part of the small intestine is then connected to the lower part to ensure the flow of digestive juices. Finally, the surgical incisions are closed using sutures or staples.
The procedure typically takes between two to three hours, and after completion, the patient is transferred to the recovery room for monitoring before being discharged from the hospital.
