Question

what is dehydration
​

Answer 1

Answer:

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. If you don't replace lost fluids, you will get dehydrated

Dehydration can have causes that aren't due to underlying disease. Examples include heat, excessive activity, insufficient fluid consumption, excessive sweating or medication side effects.
