If you have a high blood sugar level exceeding 180 mg/dl, the best way to bring it to a normal range is to drink a large glass of water and exercise, for instance, by taking a quick walk. If hyperglycemia persists more than three times in 2 weeks, seek medical attention from a specialized doctor. If your blood glucose meter indicates that your blood sugar is lower than 70 mg/dl, you can promptly do one of the following things: Chew four glucose tablets, drink 4 ounces of regular soda and not diet soda, chew four pieces of hard candy or drink 4 ounces of fruit juice.
