Retest: You may wish to have your fasting blood glucose retested. Do fast overnight before the test. Minimum fasting time is 8 hours. If the repeat result is higher than 110 mg/dL, you should consult an endocrinologist as the results would indicate prediabetes. You can reduce the risk of diabetes through weight loss and exercise. Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.
