Definition Dehydration occurs when you use or lose more fluid than you take in, and your body doesn't have enough water and other fluids to carry out its normal functions. Dehydration is dangerous especially for children and older adults. Causes Dehydration is simply caused by not drinking enough water sometimes. Other causes include:
  • Diarrhea, vomiting. They can cause a tremendous loss of water and electrolytes in a short amount of time.
  • Fever. In general, the higher your fever, the more dehydrated you may become.
  • Excessive sweating. If you do vigorous activity and don't replace fluids as you go along, you can become dehydrated.
  • Increased urination. Certain medications, such as diuretics and some blood pressure medications cause you to urinate more and get dehydration.
