This is a condition that can occur due to the complications affecting some diabetics; this is when the blood sugar drops to low. The blood sugar can drop below 3.9 millimoles per liter. This can make the body feel shaky, sweat and have a rapid heartbeat.

These symptoms should be a warning sign that the blood sugar is rising too quickly, but the diabetic that has complications like autonomic neuropathy may not realize they are suffering from hypoglycemia. This can create a dangerous situation; because hypoglycemia can be dangerous to the body and if not treated can be fatal.
