What is a Mini Gastric Bypass

Estimated Reading Time: 3 minutes

When it comes to gastric bypass surgeries, there are two different kinds: the traditional gastric bypass and the mini gastric bypass. A mini gastric bypass performs the same purpose as a traditional gastric bypass, however the main difference is that it makes the stomach much smaller and reroutes the small intestine.

A mini bypass takes less time to perform than the traditional gastric bypass, and it’s also a more straightforward procedure out of the two. It’s becoming the more popular choice, as it offers similar results when it comes weight loss and health benefits.


How much weight can you lose with mini gastric bypass?

Understanding how much weight you can lose with a mini gastric bypass will vary for each individual. The surgery involves shrinking the size of your stomach so that you can only eat small amounts of food in one go, aiding weight loss.

Typically, most patients can expect to lose around 60-70% of their excess weight over a 2-year period. Some may lose a little more, some may lose a little less, but those patients who stick closely to their diet and exercise regularly can expect to lose up to 70% of their excess weight.


How long does mini gastric bypass last?

On average, a mini gastric bypass surgery can take about 45 minutes to an hour to perform, however keep in mind that it will differ according to each patient and surgeon.

Compared to the traditional gastric bypass surgery though it is a much quicker and simpler procedure, with a much lower risk of surgical errors or complications. A full gastric bypass surgery can take anywhere between two to four hours.


Is a mini gastric bypass reversible?

A mini gastric bypass can be reversed in some circumstances. This is made possible by the fact that no part of the stomach has been fully removed – instead it has been divided into two sections. To reverse this, the staples used to divide the stomach in half can be removed and the stomach can then be moved back into its original position.

However, it’s important to keep in mind that mini gastric bypass reversal is not recommended unless serious complications arise that warrant this. Reversal is an option for those that are suffering from side effects from the surgery, such as infections, malnutrition, bowel obstruction, or stomach perforations.

Whilst a mini gastric bypass is a simple procedure in itself, a reversal is often a lot more complicated. If the situation arose, you’d need to discuss your options with your doctor to understand both the risks and benefits of a reversal.


What is the difference between a mini bypass and a sleeve?

The main difference between a gastric sleeve and a mini gastric bypass is the reduction in the size of your stomach. Gastric sleeve surgery creates a pouch that that holds about 3 ounces, whilst with a mini gastric bypass your pouch can hold up to about 1 ounce.
