Hi! The major side effects of eurepa are weight gain,joint pain and diarrhea. Controlling blood sugar requires a three pronged strategy - the right diet, the right exercise and the right drug combination. If any of the three is out of sync it is going to be hard to get your sugar levels in the normal range.You ll need a dietitian to give you a diet plan and a discussion with your doctor about the kind of exercise to benefit your mother. Finally the drug combo will have to be configured according to your your mother s metabolic assessment by your doctor. All the best!
