Thirst is your body’s way of telling you that it’s running low on water, which it needs to work well. It’s normal to feel thirsty when it’s hot or after you’ve powered through an intense workout.
But if you’re constantly refilling your cup without relief, it could signal another health problem.
Dehydration means your body doesn’t have enough water to carry out normal tasks, and thirst is the main symptom. It can happen for a lot of reasons, such as exercise, diarrhea, vomiting, and too much sweating.
Besides wanting water, other signs can include:
- Dark-colored urine
- Not needing to pee as often
- Dry mouth
- Dry skin
- Feeling tired or lightheaded
Kids who are dehydrated might also:
- Have few or no tears when they cry
- Have a dry, sticky mouth
- Go to the bathroom less or have fewer wet diapers
- Be irritable or sluggish
Thirst you can’t seem to quench, what doctors call polydipsia, is one symptom of diabetes. When you have this disease, your body doesn’t make enough of the hormone insulin or doesn’t use it properly. It causes too much sugar (called glucose) to build up in your body.
