Gastric Bypass Surgery
Gastric bypass surgery, also known as Roux-en-Y gastric bypass, is a surgical procedure designed to aid weight loss in individuals with obesity. It involves creating a small pouch at the top of the stomach and rerouting the digestive system to bypass a portion of the small intestine. By reducing the stomach's capacity and altering the digestion process, gastric bypass surgery helps patients achieve significant and sustainable weight loss.

Gastric bypass surgery is a type of weight loss surgery that helps people lose weight by changing how their stomach and small intestine handle food. After the surgery, the stomach is made smaller and the small intestine is bypassed. This makes it harder to eat and absorb calories, which leads to weight loss.
Procedure of Gastric Bypass Surgery
-
Preoperative Evaluation: Before undergoing gastric bypass surgery, patients undergo a thorough evaluation to assess their eligibility and overall health. This typically includes physical examinations, blood tests, imaging studies, and consultations with a multidisciplinary team of healthcare professionals, including surgeons, dietitians, and psychologists.
-
Anesthesia and Incisions: Gastric bypass surgery is performed under general anaesthesia, ensuring that the patient is comfortable and unaware of the procedure. The surgeon then makes small incisions in the abdomen, usually using a minimally invasive technique known as laparoscopy.
-
Creation of the Pouch: Using surgical instruments, the surgeon divides the stomach, creating a small pouch at the top. This new pouch restricts the amount of food that can be consumed, leading to earlier feelings of fullness.
-
Rerouting the Digestive System: The surgeon then bypasses a portion of the small intestine by connecting the lower end of the divided small intestine directly to the small stomach pouch. This rerouting reduces the amount of nutrients and calories the body absorbs from food.
-
Closure and Recovery: After ensuring the connections are secure, the surgeon closes the incisions with sutures or staples. The patient is then closely monitored during the initial recovery period, which typically involves staying in the hospital for a few days.
Postoperative Care: Following gastric bypass surgery, patients must adhere to a specialised diet and adopt a healthy lifestyle. This includes consuming small, nutrient-dense meals, avoiding high-calorie foods, and engaging in regular physical activity. Ongoing medical supervision and support from healthcare professionals are crucial for long-term success
