Hi Schlep: Not sure if Cipro can cause your blood sugar to rise, but whatever you're taking it for probably can. I've had a cold/bronchitis for about 10 days and am also on antibiotics. My blood sugars have been quite a bit higher than normal. I have blamed it on the infection. Any stress to the body can certainly cause elevation, be it physical or mental stress. This was my first cold since diagnosis. I've heard others post about higher blood sugars when they are sick.
Hope you're feeling better soon!
