Gastric Bypass Surgery Support Group
Gastric bypass (GBP) is any of a group of similar operative procedures used to treat morbid obesity, a condition which arises from severe accumulation of excess weight in the form of fatty tissue, and the health problems ("co-morbidities") which result. If you are considering gastric bypass or have had it, join the community where we share our experiences and find support.

I had problems with low sugars during my pre-op liquid diet but my surgeon allowed things like cottage cheese and yogurt to help maintain my sugars.
Once I had my surgery, (10 weeks ago), when I would have a low sugar, I would take a Glucose tab to bring it up. I was following the instructions per my surgeon & PCP. I do have some low sugars once in a while but pretty much they're staying around 113. My last A1c, which was April 2nd, was 5.5. That's down from 10.8 so I'm definitely doing better.
Speak with your primary care and your surgeon about your concerns. They should be more than happy to help you. Good luck!!
