Hypoglycemia

An imbalance of glucose levels (low level) caused by various factors. Signs and symptoms include sweaty or clammy skin, hunger, feeling confused, dizziness, rapid heart rate, feeling nervous or shaky, and mood changes.


Abnormally low level of blood sugar.


An abnormally low blood glucose concentration, characterized by a number of symptoms such as dizziness, nausea, headache, heart palpitations, confusion, forgetfulness.


Concentrations of glucose in the blood are lower than normal.


Deficiency of normal glucose levels in the body; low blood sugar.


A condition characterized by an abnormally low blood glucose level. Severe hypoglycemia is rare and dangerous. It can be caused by medications such as insulin (those with diabetes mellitus are prone to hypoglycemia), severe physical exhaustion, and some illnesses. The significance of reactive hypoglycemia—a lowering of blood sugar levels after meals in some people—is uncertain, but the symptoms reported, such as lightheadedness, weakness, and rapid heartbeat, usually do not correlate with blood sugar levels.


An abnormally low level of sugar in the blood, which can cause such symptoms as confusion, coma, trembling, sweating, and even death.


Low blood sugar. Physiological is normal, which helps to make a person hungry. Pathological is a rare condition in which severe symptoms occur when the blood sugar drops very low.


Abnormally low levels of glucose (a sugar used in the body for energy) in the blood, common among people with diabetes mellitus who are treating themselves with insulin; also called insulin shock.


Lower than normal blood glucose level (<80 mg/dL blood or 4 mmol/L).


Hypoglycemia is a below normal concentration of glucose in the blood. Symptoms of hypoglycemia include dizziness, muscle weakness, fatigue, and hunger. When blood glucose concentration drops below normal, glucagon is secreted, which mobilizes glycogen from the liver to elevate blood glucose concentration.


Hypoglycemia is a clinical syndrome that results from an imbalance between glucose production and glucose utilization such that glucose levels in the bloodstream are depleted faster than they are replaced. Hypoglycemia is defined by a blood glucose concentration less than 2.2 mmol/L. Hypoglycemia deprives the brain and nervous tissue of their primary source of energy and, as a result, may cause central nervous system dysfunction. Causes of hypoglycemia are highly varied and include numerous metabolic and endocrine disorders. Recent reviews have identified as many as 12 distinct hypoglycemic disorders and over 30 causes of hypoglycemia.


lower than normal level of glucose in the blood, usually resulting from administration of too much insulin (in diabetes mellitus), excessive insulin secretion from the pancreas, or poor diet. Symptoms include headache, weakness, anxiety, personality changes, and, if severe and untreated, coma and death. Treatment is by administration of glucose.


Abnormally low level of blood glucose due to either inadequate caloric intake or excess insulin production.


Abnormally low blood sugar levels, which may be caused by excessive insulin secretion or intake, fasting, certain drugs or foods, or disease.


Low blood sugar. Hypoglycemia occurs when the blood level of glucose becomes too low to supply the need for fuel in the body. In people who take insulin, hypoglycemia is sometimes referred to as an insulin reaction because it is a response to excessive insulin in the bloodstream. It is generally defined as a blood sugar level lower than 6o milligrams per deciliter (mg/dL). It most commonly occurs in people with type 1 diabetes. But sometimes hypoglycemia may occur in people with type 2 diabetes if they take certain diabetes medications or insulin.


A deficiency of glucose in the bloodstream, causing muscular weakness and incoordination, mental confusion, and sweating. If severe it may lead to hypoglycemic coma. Hypoglycemia most commonly occurs in diabetes mellitus, as a result of insulin over-dosage and insufficient intake of carbohydrates. It is treated by administration of glucose, by injection if the patient is in a coma; by mouth otherwise.


An abnormally low level of glucose in the blood, often associated with neurological side effects and arousal of the sympathetic nervous system. Medication induced hypoglycemia is a common occurrence during the treatment of diabetes mellitus.


A condition in which the body produces too much insulin, resulting in low blood sugar.


A less than normal level of sugar in the blood, usually caused by being given too much insulin, excessive release of insulin by the pancreas, or low food intake.


A condition marked by unusually low blood glucose levels, potentially causing symptoms like trembling, cold sweats, goosebumps, hypothermia, and headaches, along with irritability, confusion, hallucinations, strange behavior, and ultimately, seizures and coma.
