What to do if i know what to do if my blood sugars go too low, but what about if they go too high?

Blood sugars: Do not go too low unless you are on diabetes medication or have end stage cancer, kidney or liver disease, etc. Your body protects you from low glucose. You are probably overweight and Insulin resistant, and feeling a rapid return to normal after a meal. If your sugar is actually too high, then you have diabetes and need to see your doctor.
