Gastric bypass surgery, also known as Roux-en-Y gastric bypass (RYGB), is a surgical procedure aimed at helping individuals with severe obesity achieve significant and sustained weight loss by altering the anatomy of the digestive system.  The process begins with a comprehensive evaluation by a bariatric surgeon to assess the patient's medical history, weight history, coexisting medical conditions, and suitability for gastric bypass surgery. This evaluation may include physical examinations, blood tests, imaging studies, nutritional assessments, and consultations with other healthcare providers as needed. The key thing is to provide your body mass index as more than 60% of bariatric surgery clinics do not accept low body mass indexes, generally below 0.8 so your clinic choice need also to be based on that not to be rejected and waste time.

The second step in paralell with your online consultation will be to get an online quote with all details and in most cases to be advised a small diet before starting the procedure. This may involve consuming a low-calorie, high-protein diet, abstaining from smoking and alcohol, and engaging in regular physical activity. The most efficient is to be prescribed injections.

Gastric bypass surgery is typically performed under general anesthesia in a hospital operating room. The procedure involves making several small incisions in the abdomen and using laparoscopic (minimally invasive) techniques to access the stomach and intestines. During the surgery, the surgeon creates a small pouch at the top of the stomach by stapling or dividing it, limiting the amount of food that can be consumed. Next, a section of the small intestine is divided and connected to the newly created stomach pouch, bypassing the remaining stomach and part of the small intestine. This rerouting of the digestive tract alters the absorption of nutrients and promotes weight loss.

The usual protocol is 1 or 2 nights in clinic and then 2 to 4 nights in hotel before being discharged.

Gastric bypass surgery is a highly effective treatment option for individuals with severe obesity who have not been able to achieve weight loss through diet and exercise alone. It has to be compared to gastric balloon procedure or to sleeve procedure.
