Gastric bypass is a surgical procedure designed to assist with weight loss by altering the digestive system. It involves creating a small pouch from the upper part of the stomach and connecting it directly to the small intestine, effectively bypassing a significant portion of the stomach and the initial segment of the small intestine. This modification restricts food intake and reduces nutrient absorption, leading to weight loss. Preparation: Prior to the surgery, patients typically undergo a comprehensive pre-assessment to evaluate their overall health and discuss any medications they are taking. It's crucial to adhere to specific instructions regarding fasting before the procedure. Additionally, arranging for transportation home is important, as driving immediately after the surgery is not advisable. Procedure: Performed under general anesthesia, the surgeon uses keyhole (laparoscopic) surgery to create a small pouch at the top of the stomach. This pouch is then connected directly to the small intestine, bypassing the rest of the stomach and a portion of the small intestine. The procedure typically takes around two hours to complete. Royal Berkshire NHS Recovery: Post-surgery, patients may experience some pain and discomfort, which can be managed with prescribed painkillers. It's essential to follow dietary guidelines and gradually reintroduce foods as advised by a healthcare professional. Engaging in gentle physical activity, as recommended, can aid in recovery and improve outcomes. Full recovery varies per individual but generally ranges from 4 to 6 weeks.
