Hypoglycemia Unawareness

Very often, hypoglycemia symptoms occur when blood glucose levels fall below 70 mg/dl. But, many people have blood glucose readings below this level and feel no symptoms. This is called hypoglycemia unawareness which is a state in which a person does not feel or recognize the symptoms of hypoglycemia.

People who have frequent episodes of hypoglycemia may no longer experience the warning signs of it.

People with hypoglycemia unawareness are also less likely to be awakened from sleep when hypoglycemia occurs at night.

Hypoglycemia unawareness occurs more frequently in those who:

  1. Frequently have low blood glucose episodes (which can cause you to stop sensing the early warning signs of hypoglycemia)
  2. Have had diabetes for a long time
  3. Tightly control their diabetes (which increases your chances of having low blood glucose reactions)
If you think you have hypoglycemia unawareness, speak with your health care provider. Your health care provider may adjust/raise your blood glucose targets to avoid further hypoglycemia and risk of future episodes. CLICK HERE for more information.
