Mini Gastric Bypass

The gastric bypass can be the most effective form of weight loss surgery, but it is also the most invasive. If you are looking for a slightly simpler procedure, the mini gastric bypass might be right for you.

What is the Mini Gastric Bypass?

The mini gastric bypass is similar to the more common gastric bypass surgery. However, a few changes have been made to the procedure so that the operation can be completed more quickly. During the mini bypass, your stomach will be divided in two. The smaller section will be shaped into a tube and connected to your small intestine, bypassing between two and seven feet. When you eat, food will enter this stomach pouch and then pass into your intestine. The rest of your stomach will be left in place, but food won’t be able to get into it. The main difference between this procedure and the conventional bypass is that the point where this larger part of the stomach connects with the intestine won’t change. Bile and gastric juices will be able to flow out of the unused part of your stomach and into the top of your small intestine.


The mini gastric bypass is simpler to perform than the standard bypass. It takes about 50 minutes less. Since less re-routing and reconnecting needs to be done, there is a lower risk of complications too. The effects of the surgery are often just as good as for the full bypass, so it is possible to achieve good weight loss after this procedure.


Although the mini gastric bypass might seem like the perfect alternative to the normal bypass procedure, it isn’t the right choice in every case. Since bile and gastric juices will be entering the intestine above the point where your stomach pouch is attached, there is a chance of severe acid reflux if these juices get into your stomach. This can be painful and difficult to treat. There is also a higher risk of nutritional deficiencies with the mini bypass procedure, as a longer section of intestine is usually bypassed.

It is also important to be aware that the mini bypass is a relatively new procedure. It isn’t something that all bariatric surgeons can perform, and many of those who do offer it have limited experience with the procedure. Since the procedure is so new, we are still learning about it and its effects, so it isn’t always clear whether the mini bypass is the right procedure to choose. Some health insurance providers will also be a bit wary of paying for this procedure instead of the standard gastric bypass operation. Your doctor can help you to decide which bariatric procedure is right to help with your weight loss.
