Hypoglycemia

Hypoglycemia: Introduction

Hypoglycemia, also known as low blood sugar, is an abnormal condition in which the sugar (glucose) level in the blood is too low.

Hypoglycemia can happen by itself or can be a symptom of or occur with a variety of mild to serious diseases, disorders and conditions. Hypoglycemia can be caused by over-exercising and not eating enough carbohydrates and by starvation dieting. Hypoglycemia can also occur in some people after drinking alcohol, especially large amounts of alcohol.

Serious disease, disorders and conditions that can also increase the risk of developing hypoglycemia include type 1 diabetes, insulin-secreting tumors of the pancreas, kidney disease, Addison's disease and liver disease. Hypoglycemia can also be a side effect of some medications. In some cases, it is not possible to diagnose the underlying cause of hypoglycemia. For more details on causes, refer to causes of hypoglycemia.

Hypoglycemia can occur in any age group or population. Depending on the cause, hypoglycemia can be short-term and disappear quickly, such as when hypoglycemia occurs after a single episode of over-exercising but is quickly treated by eating a meal. Hypoglycemia can also recur over a longer period of time, such as when hypoglycemia is due to kidney disease or liver disease.

Symptoms of hypoglycemia include rapid heartbeat, hunger, confusion, fatigue, cold sweats, shakiness and headache. Severe hypoglycemia that is not treated quickly can lead to unconsciousness and even death in extreme untreated cases.

Hypoglycemia is easy to diagnose during a routine office visit with a simple blood test, called a fasting blood glucose test. Hypoglycemia is generally defined as having a fasting blood sugar level of less than 55mg/dL. In an emergency, hypoglycemia can be quickly diagnosed on a random blood glucose test.

Making a diagnosis generally also includes performing a variety of tests to help to diagnose potential underlying diseases, conditions or disorders and evaluate overall health. Blood tests can include a complete blood count (CBC), chemistry panel, urinanalysis, and liver function tests. Depending on the suspected cause, tests may also include special imaging tests, such as X-ray, nuclear imaging, CT scan and/or MRI.

A diagnosis of hypoglycemia can be missed or delayed because symptoms can mimic symptoms of other conditions and for a variety of other reasons. For more details on misdiagnosis, refer to misdiagnosis of hypoglycemia.

Treatment of hypoglycemia involves ingesting foods and/or fluids that contain glucose. In severe and emergency cases, glucose may be given via intramuscular injection or intravenously. The underlying diseases, disorders and conditions also require treatment to prevent or minimize future episodes of hypoglycemia. For more details on treatment, refer to treatment of hypoglycemia. ...more »

Hypoglycemia: Hypoglycemia is a low level of sugar in the blood. When you haven't eaten recently, the body will usually produce sugar in the liver to avoid blood sugar levels falling. However, this mechanism does not always work perfect. Some people have mild hypoglycemia where they occasionally get the shakes when hungry, but are not seriously afflicted. Other people have chronic hypoglycemia where a hypoglycemic episode occurs regularly and may need medications or dietary management. When this occurs shortly after a meal it is called "reactive hypoglycemia" and when it occurs after a long period of non-eating it is "fasting hypoglycemia". Sudden and actue hypoglycemic episodes (or "hypos") are also very common for diabetics, in reaction to an imbalance between insulin or diabetes pills, level of food, and level of exercise or activity. ...more »

Hypoglycemia: Treatments

The first step in treating hypoglycemia is prevention. Prevention measures include not over-exercising and always eating a well balanced diet that contains sufficient amounts of carbohydrates. It is also important not to go on starvation or fasting diets and not to drink alcohol or to drink in moderation.

Hypoglycemia: Misdiagnosis

A diagnosis of hypoglycemia may be missed or delayed because symptoms may be mild and resolve quickly with the consumption of food and fluids that contain carbohydrates. However, in some cases, hypoglycemia can be the result of a serious condition, such as liver disease. This is why it is important to have regular medical care throughout a lifetime, even if you appear to have no ...more misdiagnosis »

Article Excerpts about Hypoglycemia

Hypoglycemia: NIDDK (Excerpt)

Glucose, a form of sugar, is the body's main fuel. Hypoglycemia, or low blood sugar, occurs when blood levels of glucose drop too low to fuel the body's activity. (Source: excerpt from Hypoglycemia: NIDDK)

Diabetes: NWHIC (Excerpt)

Hypoglycemia, or low blood sugar, is not diabetes but may occur as a complication of diabetes, as a condition in itself, or in association with other disorders. Hypoglycemia occurs when levels of glucose, the body's main fuel, drop too low to fuel the body's activity. Carbohydrates (sugars and starches) are the body's main dietary sources of glucose. During digestion, the glucose is absorbed into the blood stream (hence the term "blood sugar"), which carries it to every cell in the body. Unused glucose is stored in the liver as glycogen. In the case of hypoglycemia, the mechanism for converting stored glucose (glycogen) back into usable glucose energy (glucose) by the body is faulty. The process normally involves the liver and other organs as well as various hormones. (Source: excerpt from Diabetes: NWHIC)

Definitions of 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. - (Source - Diseases Database)

Abnormally low blood sugar usually resulting from excessive insulin or a poor diet - (Source - WordNet 2.1)
