Why is my sugar level in the 40s?

Answer by  kimber18 (514)

Very low blood sugar. You could be diabetic, not eating correctly,you may need to watch how frequently you eat,your body is metabolizing too quickly and lowering your blood sugar levels. That is getting into a very dangerous low, and could cause diabetic coma if you are not careful. Eating every two hours, including complex carbohydrates in your meals and snacks.
