How Roux-en-Y Bypass Surgery is Performed


Obesity is the most common chronic disease in modern times. Many people find it hard to lose weight by making changes in diet and lifestyle routines, due to several reasons (like underlying medical conditions or just a lack of resolve). And without managing their weight they are always at risk of developing severe complications of obesity such as type 2 diabetes, heart disease, certain type of cancers, etc. Weight loss surgery or bariatric surgery is the only option for such people to be able to lose weight and prevent those complications. It is only recommended for people who didn’t get any benefit from diet and exercise plans and are on the verge of developing obesity-related diseases. Log on to to know more about weight loss.

What is Roux-en-Y bypass surgery? 

Roux-en-Y is the French name for “gastric bypass surgery.” It is a weight loss surgery that is used for people who have obesity and suffer from or are at risk of developing obesity-related complications such as type 2 diabetes, high blood pressure, hypertension, obstructive sleep apnea, and GERD (Gastroesophageal Reflux disease). This is one of the most commonly performed weight loss surgeries.  

During this surgery, surgeons modify your digestive system in a way that makes you consume fewer calories and absorb fewer nutrients from your diet. As its name implies, the surgeon makes changes in your stomach and small intestine so that they connect making a new segment together to form a Y shape.  


In the beginning, one month before your surgery, your doctor recommends that you start some physical activities and make changes in your diet. If you’re taking some medication, please consult your doctor. And if you smoke, it’s time to quit.  

Surgery is usually given by using the laparoscopic method, which is a minimally invasive surgery technique. In this surgery, the surgeon makes 3 to 5 small incisions in your abdomen, each incision is about half an inch long. Making smaller cuts can decrease complications, less bleeding and pain, and a faster recovery.  

During the surgery, the anesthetist first gives you an injection of anesthesia that makes you fall asleep so that you don’t feel any pain during the surgery. The surgeon makes a single keyhole incision in your abdomen. The surgeon uses the first keyhole to fill carbon dioxide into your abdominal cavity to separate your abdominal wall from the other organs to see clearly. Then, the surgeon places a laparoscope, which is a small video camera with an inbuilt light above the keyhole to see the organs on a computer screen. Then, some additional incisions are made to get access to the organs.  

The surgeon divides the top portion of your stomach with a surgical stapler, so, the pouch is about the size of an egg. In the next step, to divide the small intestine they use its lower segment to attach to your new stomach pouch. Now, your food will go from your stomach pouch into this lower segment of the small intestine. And lastly, they reattach the upper branch of the small intestine to the trunk further down. 

The small intestine has two branches attached to the trunk, one to the stomach, and the other to the rest of your stomach. The right side of the branch makes “Y” which is your new branch where your food will pass. And the left side is the original upper part of your small intestine where your liver, gallbladder, and pancreas pass their digestive juices. The Left branch gets these juices from the new trunk of your small intestine, where they mix with your food. This increases your ability to digest your food properly even though you now have a shortened intestinal pathway that absorbs fewer nutrients from it.  

The surgery takes a few hours, and you wake up in the recovery room, where a nurse monitors your vitals for any complications. Your recovery depends on your health, usually, people stay in the hospital for one or two days at most. After your surgery, you need to follow a liquid diet for several weeks, followed by a pureed diet, and then you can return to solid food.
