Is having a fasting blood sugar level of 106 high? (I had two cups of black coffee before the test)

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. ...Read more

Eat healthily and exercise regularly ...Read more
