Gastric bypass surgery, also known as Roux-en-Y gastric bypass, is a weight loss procedure that involves altering the digestive system to help patients lose weight. It's a significant decision and one that requires careful consideration. In this article leading consultant bariatric and upper GI surgeon Dr Antanas Mickevicius explores what gastric bypass surgery entails, who might benefit from it, and what to expect during and after the procedure.

 

 

Understanding gastric bypass surgery

 

Gastric bypass surgery works by creating a smaller stomach pouch and rerouting the small intestine. This reduces the amount of food you can eat and the number of calories and nutrients your body absorbs. Essentially, it helps you feel full more quickly and reduces the absorption of calories, leading to weight loss.

 

Who may benefit from gastric bypass?

 

Gastric bypass surgery is typically recommended for individuals who are severely obese, with a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with health problems linked to obesity, such as type 2 diabetes , high blood pressure or sleep aponea. It's important to note that gastric bypass is not a quick fix for weight loss but rather a tool to support long-term weight management.

 

What can I expect during the procedure?

 

Before undergoing gastric bypass surgery, you will undergo a thorough evaluation to ensure you're a suitable candidate and to discuss the risks and benefits of the procedure. The surgery itself is usually performed under general anaesthesia in a laparoscopic way (using small incisions and a camera).

 

During the procedure, the surgeon will divide the stomach into a small upper pouch and a larger lower pouch. The small intestine is then reconfigured to connect both pouches, bypassing the bottom part of the stomach and a section of the small intestine.

 

Recovery and lifestyle changes

 

After surgery, you'll need to follow a strict diet and lifestyle plan to support your weight loss and ensure optimal healing. This typically involves a gradual transition from liquid to soft foods, followed by a long-term commitment to healthy eating habits and regular physical activity.

 

It's important to understand that gastric bypass surgery is very safe procedure, but not without risks. Some of the rare postoperative complications could beinfection, blood clots, and nutritional deficiencies. However, for the majority of patients, the potential benefits of significant weight loss and improvement in obesity-related health conditions outweigh the risks.

 

Gastric bypass surgery is a major decision that requires careful consideration and thorough discussion with your surgeon. While it can be an effective tool for weight loss and improving overall health, it's important to understand the weight loss journey and commit to the necessary lifestyle changes for long-term success. If you're considering gastric bypass surgery, be sure to consult with a qualified medical professional to determine if it's the right option for you.
