I was on diuretics for my hypertension for years before I was diagnosed as a diabetic.
From (CARDIOLOGY, May 23, 2012, Effects of Thiazide Diuretics on Glucose Metabolism. Joel M. Gore, MD reviewing Stears AJ et al. Hypertension 2012 May).
In the first trial, 41 patients had a significant increase in blood glucose during a 2-hour oral glucose tolerance test (OGTT) after 4 weeks of bendroflumethiazide treatment, but not after 4 weeks of atenolol treatment.
Things that make me go — Hmmm.
