I walk 1 mile at least, daily. Eat what the diabetic counselor said, drink water, and test my blood daily. The levels were 120 fasting and 134 fasting when I tested earlier those days. I got the symptoms of low sugar levels/ high sugar levels later, so I tested, the levels were 60. I got the level up to 90 within 15 minutes. She had told me that unless I was on insulin, it would not do this. Obviously it is happening I am not on diabetes medication. Any suggestions as to why it is doing this?
