It’s normal to sometimes feel thirsty but it’s not normal to constantly feel thirsty even when you’re drinking a lot. See a GP to find out what’s causing your excessive thirst.
Why am I always thirsty?
Most of the time if you’re feeling thirsty it’s because you need to drink more fluids. This can happen if you:
- sweat a lot after doing exercise
- are unwell with sickness and diarrhoea
- don’t drink enough fluids
- drink too much alcohol or caffeine
- eat salty or spicy food
- have a high temperature of 38C or above
- are pregnant
See a GP if you have excessive thirst and:
- drinking more fluids for several days hasn’t helped
- you frequently need to pee
- you’re pregnant
The treatment you have will depend on what’s causing your excessive thirst.
Is it dry mouth or excessive thirst?
You may think you’re thirsty when you actually have a dry mouth.
If it’s a dry mouth you may have:
- a burning sensation or soreness in your mouth
- changes in your sense of taste
- difficulty speaking, eating or swallowing.
