How many glasses of water did you drink today?
Dehydration occurs when you use or lose more fluid than you take in.
Anyone may become dehydrated, but the condition is especially dangerous for young children and older adults.
The signs and symptoms of dehydration are: Dry mouth and tongue, extreme thirst, less frequent urination, dark-colored urine, confusion, fatigue, dizziness etc.
You can usually reverse mild to moderate dehydration by drinking more fluids, but severe dehydration needs immediate medical treatment.
Prevention
To prevent dehydration, drink plenty of fluids and eat foods high in water such as fruits and vegetables.
Letting thirst be your guide is an adequate daily guideline for most healthy people.
People may need to take in more fluids if they are experiencing conditions such as:
- Vomiting or diarrhea.
- Strenuous exercise.
- Hot or cold weather.
- Illness. Older adults most commonly become dehydrated during minor illnesses — such as influenza, bronchitis or bladder infections. Make sure to drink extra fluids when you're not feeling well.
