Bariatric Surgery/High blood sugar after surgoery


I am 2 weeks post surgoery and wonder why my blood sugar is higher than what it was before surgoery and on medicine?

It is uncommon to see blood sugar rise during the two weeks after bariatric surgery (sometimes there is an increase during the first 48 hours due to a natural stress response).

Your question did not include information about what type of surgery you had done, but as a general rule patients should avoid consuming sugar in their fluids and in food.  One tricky thing is that some liquid protein supplements have a very high sugar content so it is necessary to carefully to choose one with more protein than carbs.  

To really address your specific circumstances I have to recommend that you consult with your surgical team, probably starting with the surgeon or the dietician.

Best of luck!

I can answer medically oriented questions about bariatric surgery including: patient selection, preparation for surgery, differences between types of bariatric surgery, aftercare following bariatric surgery. I can answer detailed questions about gastric bypass, Lap-Band, gastric sleeve, and revision bariatric surgery. I am only somewhat familiar with Biliopancreatic diversion. I am not prepared to answer insurance or other financial questions related to bariatric surgery.


I have been a practicing bariatric surgeon since 1995. About 85% of my current practice consists of bariatric surgery, including all of the above procedures except biliopancreatic diversion. I am the senior surgeon of a 5-surgeon group. I am recognized among surgeons and other medical professionals as the most experienced bariatric surgeon in my region.
