My mother have been taking hyzaar for the last 4 months and took cozaar for more than 10 years. She was diagnosed now with gastroparesis. She was not diabetic, but her blood sugar levels now are between 110-128. She is 78 yrs.old, weights 132 lbs.,5' tall and does more than an hr.of exercise daily. One dr. suggested that gastroparesis can be caused by medications. Is that correct?
