I am a 5' 8" female who weighs 135lbs. I exercise routinely, but love my chocolate! lol! I have been on a beta blocker for the past 11 years for a fast heart rate. Over the course of the past 5 years, during routine blood work, my FBS has been ranging anywhere from 102 to 128. (It should also be noted that I checked my own blood sugars one and two hours after eating on a few occasions and found that my readings went in excess of 200. On my most recent blood work a few months ago, my family doctor voiced his concern that I was indeed pre-diabetic and that I should watch what I eat. I ask him about my beta blocker and if it could cause this. He did not feel that it could, as it is a cardo select version. I decided, (with his approval) that I would wean myself off of the beta blocker and see if my blood sugars improved at all. I needed to prove this to myself...is it the medication OR do I in fact have pre-diabetes. If so, I wanted to get "on the ball" and watch my diet better. I have been off of the medication fully now for the past 12 days. My blood sugar readings have DRAMATICALLY lowered, back to the normal range! I was taking a very low dose of beta blocker, Zebeta (bisoprolol) 2.5 mg daily. This was a very welcome surprise as you can imagine. My point....I want people out there to know that this can happen. So many people are placed on beta blockers for high blood pressure etc, and may be diagnosed with diabetes. Perhaps some folks out there in this world may NOT indeed have it! Please talk to your doctor if you take one of these meds!
