About Hypoglycemia
Learn More About Hypoglycemia
Hypoglycemia, also known as low blood sugar, occurs when your blood glucose levels
(the level of sugar in the blood) drop too low to provide enough energy for your
body's activities. In adults or children older than ten years of age, hypoglycemia
is uncommon except as a side effect of diabetes treatment, but it can result from
certain medications, diseases, hormone or enzyme deficiencies, and tumors.
The Importance of Glucose
Glucose, a form of sugar, is an important fuel for your body. After a meal, glucose
molecules are absorbed into your bloodstream and carried to the cells, where they
are used for energy. Insulin, a hormone released by the pancreas, then helps the
glucose enter the cells. Extra glucose can then be stored in your liver and muscles
in a form called glycogen.
When blood glucose begins to fall, glucagon, another hormone produced by the pancreas,
signal the liver to break down glycogen and release glucose, causing blood glucose
levels to rise. In people with diabetes, this glucagon response to hypoglycemia
may be impaired, making it hard for blood glucose levels to return to normal.
