As hypoglycemia worsens, signs and symptoms can include: Confusion, abnormal behavior or both, such as the inability to complete routine tasks. Visual disturbances, such as blurred vision. Seizures.

Does low blood sugar cause confusion?

Extremely low blood sugar levels may cause you to be confused, or disoriented. Severely low levels of blood sugar may cause coma. You may have a fast heartbeat, or feel palpitations.

Why does confusion occur with hypoglycemia?

All of these hormones cause the liver to release glucose into the blood, but sometimes these hormones do not raise the blood glucose level enough to overcome the hypoglycemia. If the blood glucose level remains too low, the brain will get insufficient fuel, resulting in confusion, seizures, or loss of consciousness.
