Hi and welcome, Nana Monster. Some medications (both prescript
ions and over the counter) will raise blood sugar so we really have to be careful. Here is a website that has very valuable information about
everything regarding diabetes, including a section on
What is Normal Blood Sugar.
http://www.bloodsugar101.com/ Metformin has been an effective medication and is prescribed in different strengths. It's really important to try to keep your blood sugar as near-normal as possible because elevated blood sugar over an extended period of time can lead to damage of several organs.
Good luck and thank you for posting!
