What are the causes of dehydration? How do you know if you are dehydrated and how can it be prevented?
Dehydration is a significant loss of water in the body. The human body is made of 60% water. Depending on how much fluid is lacking, an individual can experience a mild, moderate or severe dehydration.
Causes of dehydration ranges from simple to complex reasons: Mild dehydration occur with minor reasons such as when you don’t feel like drinking, when you forget to drink or when you are too busy to remember to drink. Beyond this, situations such as high fever, diarrhea, vomiting, excessive sweating or having excessive urination (due to some other comorbidities) can lead to severe dehydration.
You might want to check if you need to rehydrate next time you have headache. This is because headache is one of the signs of dehydration.
Unexpected rapid heart rate or unusual dizziness, skin dryness, dry mouth and tongue are reflective signs predicting a need for rehydration.
Don’t forget the cardinal sign of dehydration called ‘thirst.’ It creates a crave and an ardent desire to drink some fluid, it brings about a sensation of dryness in the throat and mouth. Not until satisfied, this desire never goes away. Grab a glass of water next time you begin to feel thirsty! It will take care of some unpleasantness.
Other clinical signs of dehydration to watch out for include poor skin turgor, less urine output compared to normal (30cc urine output per hour for an adult).
Unless clinically contraindicated, water is the antidote for dehydration. Going by the rule of thumb, drinking at least six to eight glasses of water a day is highly recommended.
Note: A glass of water is 8 (fl) Oz or 240cc.
