Most of the time if you're feeling thirsty it's because you need to drink more fluids.
Drink more fluids and avoid alcohol or caffeine to see if it helps. If you do not, you may be at risk of becoming dehydrated.
- drinking more fluids for several days has not helped
- you frequently need to pee
- you're pregnant
The GP will check if your excessive thirst is being caused by something - for example, diabetes, anaemia or medicines you're taking.
The treatment you have will depend on what's causing your excessive thirst.
You may think you're thirsty when you actually have a dry mouth.
