If your glucose has dropped to an extremely low level (hypoglycemia is less than 70 mg/dL) ,yes, you need to call your doctor to problem solve why it occurred so you can reduce the risk of it happening again. Your doctor would consider adjusting medication. Neurological damage is possible with repeated or a single prolonged episode of hypogycemia. Remember, once you have had a low, you are at higher risk for another low. Go make that call!
