  • Decreased glucose level
  • Hypoglycemia
  • Hypoglycemia-induced convulsion
  • Hypoglycemic disorder
  • Hypoglycemic encephalopathy
  • Hypoglycemic shock

Clinical Information

  • HYPOGLYCEMIA-. a syndrome of abnormally low blood glucose level. clinical hypoglycemia has diverse etiologies. severe hypoglycemia eventually lead to glucose deprivation of the central nervous system resulting in hunger; sweating; paresthesia; impaired mental function; seizures; coma; and even death.
  • CONGENITAL HYPERINSULINISM-. a familial nontransient hypoglycemia with defects in negative feedback of glucose regulated insulin release. clinical phenotypes include hypoglycemia; hyperinsulinemia; seizures; coma; and often large birth weight. several sub types exist with the most common type 1 associated with mutations on an atp binding cassette transporters subfamily c member 8.

Information for Patients


Hypoglycemia

Also called: Low blood sugar

Hypoglycemia means low blood glucose, or blood sugar. Your body needs glucose to have enough energy. After you eat, your blood absorbs glucose. If you eat more sugar than your body needs, your muscles, and liver store the extra. When your blood sugar begins to fall, a hormone tells your liver to release glucose.

In most people, this raises blood sugar. If it doesn't, you have hypoglycemia, and your blood sugar can be dangerously low. Signs include

  • Hunger
  • Shakiness
  • Dizziness
  • Confusion
  • Difficulty speaking
  • Feeling anxious or weak

In people with diabetes, hypoglycemia is often a side effect of diabetes medicines. Eating or drinking something with carbohydrates can help. If it happens often, your health care provider may need to change your treatment plan.

You can also have low blood sugar without having diabetes. Causes include certain medicines or diseases, hormone or enzyme deficiencies, and tumors. Laboratory tests can help find the cause. The kind of treatment depends on why you have low blood sugar.
