A person with abnormally low levels of blood sugar (glucose) has hypoglycemia. Glucose is the body's main energy source. Hypoglycemia is not a disease in itself; it is a sign of a health problem. The majority of people know when their blood sugar levels have dropped, and have time to do something about it. The typical signs of low sugar levels are hunger, trembling, shakiness, nausea, pallor, and sweating. Hypoglycemia is commonly linked with diabetes. Many other conditions can cause low blood sugar in people who do not have diabetes.
