Dehydration is an abnormal condition in which the body's cells are deprived of an adequate amount of water. Dehydration can be the result of conditions that cause the body to lose too much water, such as excessive heat, sweating, illness, low humidity, medication side effects, and high elevation, such as in the mountains. Dehydration can also be the result of not drinking enough water and fluids.
Dehydration can be mild, moderate or severe and life-threatening. Infants, children, athletes and the elderly are particularly prone to dehydration and severe complications, although dehydration can occur in any age group or population. In an otherwise healthy person, dehydration can be prevented by drinking about eight eight ounce glasses of water per day.
Adequate amounts of water, or good hydration, is necessary to prevent dehydration. Water is a vital substance in the body. It makes up about 70 percent of the muscles, organs, and solid tissue in the body and is crucial to many of the body's processes. Dehydration negatively affects such functions as eliminating toxins, delivering nutrients, carrying oxygen to the cells of the body, producing energy, and lubricating joints. Dehydration can impact proper balance of vital electrolytes, such as sodium and potassium, which are also essential to healthy functioning of the body.
Dehydration can be acute and appear relatively suddenly, such as dehydration that occurs with a new case of type 1 diabetes. Dehydration can also be ongoing and chronic, such as can occur an elderly person who does not drink enough fluids because of a fear of incontinence.
Dehydration can also be a symptom of a diseases, such as aldosterone deficiency and type 1 diabetes. Dehydration can be the result of a wide variety of other conditions, diseases or disorders. These include vomiting, diarrhea, alcohol intoxication, fever, cholera, jet lag and gastroenteritis. Dehydration can also result from taking diuretic medications, such as furosemide (Lasix), which cause the body to lose water.
Symptoms of dehydration include thirst, and dry lips and tongue. Complications of dehydration can be serious, even life-threatening and include shock, coma and death. For more details about symptoms and complications, see symptoms of dehydration.
Diagnosing dehydration and its root cause begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination. Diagnostic testing that is performed generally includes a chemistry profile, which measures levels of electrolytes, such as sodium and potassium.
A complete blood count can reveal blood that is abnormally concentrated due to a lack of water. A urine specific gravity test is a test that measures the specific gravity of urine, which is elevated with moderate to severe dehydration. A BUN and creatinine test measures kidney function and substances that may be abnormally high in the blood in dehydration.
Making a diagnosis also includes performing a variety of other tests to help to diagnose the underlying disease, condition or disorder causing the dehydration. This generally includes blood sugar testing to check for diabetes.
A diagnosis of dehydration and its cause can easily be delayed or missed because some people may be unaware that they have become dehydrated. For information on misdiagnosis, refer to misdiagnosis of dehydration.
Treatment of dehydration involves rehydration using oral or intravenous fluids and treating any underlying disease, disorder or condition that may be causing the dehydration. For more information on treatment, refer to treatment of dehydration. ...more »
