Causes of Dehydration

Tuesday, March 3rd, 2009

Dehydration is caused by water loss or by inadequate water intake. The commonest cause is failure to drink enough water, although severe perspiration is a significant cause in hot climates or bouts of hot weather. Fluid loss caused by episodes of diarrhea (especially in children and old people) can also cause rapid dehydration.

In addition, loss of sodium (salt) from the body typically leads to a loss of water. Therefore, abnormally low levels of salt in body fluids may cause a person to become dehydrated. Kidney (renal) failure and Addison’s disease (adrenal cortical insufficiency) are two conditions that may – if untreated – lead to sodium depletion and dehydration.

Home Based Treatment for Dehydration

Wednesday, February 18th, 2009

Dehydration occurs over time. If it can be recognized in its earliest stages, and if its cause can be addressed, then home treatment may be adequate.

Steps a person can take at home to prevent severe dehydration include:

  • Patients with vomiting and diarrhea can try to alter their diet and use medications to control symptoms to minimize water loss.
  • Acetaminophen or ibuprofen may be used to control fever.
  • Fluid replacements may be attempted by replacing fluid by mouth with frequent small amounts of clear fluids (see clear fluids information in previous section).

If the patient becomes confused or lethargic; if there is persistent, uncontrolled fever, vomiting, or diarrhea; or if there are any other specific concerns, then medical care should be accessed.

What is Dehydration ?

Tuesday, February 3rd, 2009

Dehydration can be defined as “the excessive loss of water from the body.” Dehydration is a condition that occurs when a person loses more fluids than he or she takes in. Our bodies require a certain amount of fluid intake on a daily basis to function; the minimum is about equal to 8 glasses (one liter or one quart). Requirements vary with activity and age, but most active persons need two to three times this basic amount. Basic fluid intake serves to replace the fluids which are required to perform our normal bodily functions. If we take in less or lose more fluid than is needed, the end result is dehydration.
