Hypoglycemia

Hypoglycemia unawareness

Over time, repeated episodes of hypoglycemia can lead to hypoglycemia unawareness. The body and brain no longer produce signs and symptoms that warn of a low blood sugar, such as shakiness or irregular heartbeats. When this happens, the risk of severe, life-threatening hypoglycemia is increased.

Undertreated diabetes

If you have diabetes, episodes of low blood sugar are uncomfortable and can be frightening. Repeated episodes of hypoglycemia may cause you to take less insulin to ensure that your blood sugar level doesn't go too low. But long-term high blood sugar levels can be dangerous too, possibly causing damage to your nerves, blood vessels and various organs.
