Dehydration – Symptoms & Treatment


Your body becomes dehydrated because it lacks the water and other fluids it requires to function correctly when you use or lose more fluid than you take in. Insufficient replacement of lost fluids will result in dehydration. Dehydration may affect everyone, but it is particularly harmful to small children and elderly people. Dehydration in young children is most frequently that arises due to severe diarrhea and vomiting.

It is more likely to occur in older persons because they naturally have a lower water content in their bodies and may also be caused by medical problems or drugs. If you do not drink enough water in hot weather, especially if you are moving hard, dehydration can occur in people of any age. You may normally cure mild to moderate dehydration by drinking more fluids. But severe dehydration needs immediate medical assistance.

This is why it’s crucial to drink more water during hot weather or when you’re sick. Age-related differences in dehydration symptoms and indications are also possible.

Increased Urination
