Severe low blood sugar is a medical emergency. It can cause seizures and brain damage. Severe low blood sugar that causes you to become unconscious is called hypoglycemic or insulin shock. Even one episode of severe low blood sugar may make it less likely for you to have symptoms that allow you to recognize another episode of low blood sugar.
Hypoglycemia: Causes, Diagnosis, and Treatment. Hypoglycemia describes an abnormally low level of sugar (glucose) in the blood. Hypoglycemia is not a disease in itself, rather it is a sign of a health problem. The brain needs a continuous supply of glucose to function because it can neither store nor manufacture glucose. The typical signs of low sugar levels include hunger, trembling, heart racing, nausea, and sweating. Hypoglycemia is commonly linked with diabetes, but many other conditions can also cause low blood sugar. In this article, we will discuss the causes, diagnosis, and treatment of hypoglycemia.
