Aspiring Bariatrics is pleased to start offering the one anastomosis gastric bypass. This is a variation of the Roux-en-Y gastric bypass where only one join is made with the intestine rather than two. Compared to the Roux-en-Y form of the gastric bypass it may offer a slightly higher average weight loss outcome and may also be slightly more effective for type 2 diabetes. Due to the longer length of intestine bypassed however the risks of vitamin deficiency are greater than with the Roux-en-Y gastric bypass and there is also a small risk of bile reflux requiring further surgery. For more information on this procedure please contact us.
