DEHYDRATION

Definition
Dehydration is the condition that results when too much body fluid is lost. 

What are the signs and symptoms of dehydration?
Dehydration may be mild, moderate, or severe.

  Mild dehydration can cause light-headedness, a dry mouth, and decreased urination.

  Moderate dehydration can cause sunken eyes, pale skin, and anxiety.

  Severe dehydration usually causes a weak, rapid heartbeat and low blood pressure. Severe dehydration can lead to shock and death. 

Mild dehydration has few risks, and drinking fluids can easily rehydrate the person. Dehydration is sometimes severe. Serious cases usually occur in infants, sick people, athletes, and the elderly. Unless severe dehydration is treated very quickly, death can result. 

There are usually no long-term effects with mild to moderate dehydration. Untreated severe dehydration may cause seizures, permanent brain damage, or death. 

What can be done to prevent the condition?
Early intervention is the best prevention. The body needs a constant source of fluids. Eight glasses of fluid a day are recommended to keep the body well hydrated. Sports safety includes drinking plenty of water during and after exercise to prevent dehydration. 

If a dehydrated person drinks beverages that contain caffeine, such as teas, soda, and coffee, they may feel worse. Caffeine causes more urination, so it can undo the benefit of drinking fluids. Water, and sports drinks help restore hydration and chemical balance.
