By Mayo Clinic staffHypoglycemia is a condition characterized by an abnormally low level of blood sugar (glucose), your body's main energy source.
Hypoglycemia is commonly associated with diabetes. However, a variety of conditions, many of them rare, can cause low blood sugar in people without diabetes. Like fever, hypoglycemia isn't a disease itself — it's an indicator of a health problem.
Immediate treatment of hypoglycemia involves quick steps to get your blood sugar level back into a normal range, either with high-sugar foods or medications. Long-term treatment requires identifying and treating the underlying cause of hypoglycemia.
