Clinical Information
  • A disorder characterized by laboratory test results that indicate a low concentration of glucose in the blood
  • 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
  • Abnormally low blood sugar
  • Abnormally low level of glucose in the blood
  • Hypoglycemia means low blood glucose. Your body needs glucose, a form of sugar, 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. nih: national institute of diabetes and digestive and kidney diseases
