Everyone goes too long without a drink of water.
But if it seems you are just so thirsty all of the time, then you may be wondering what’s going on.
Let’s look at seven common conditions that might cause you to be thirsty.
1. Anxiety. Thirst is frequently a result of the other symptoms of anxiety. Anxiety can make you sweat – which would lead to you being thirsty. It can give you dry mouth – which would also make you thirsty. It can make you forget about self-care, so you aren’t drinking enough water – which can make you thirsty. To be clear, just because you’re really thirsty doesn’t mean you have anxiety. But it can be related to one of the classic symptoms. If these symptoms of anxiety sound familiar, go ahead and talk to your doctor.
2. Dehydration. The most common reason for thirst is plain old dehydration. You just haven’t gotten enough to drink in too long. Combine being thirsty with dry mouth, dark yellow urine, and lightheadedness and you’re probably looking at the beginnings of dehydration. So before you do anything else, sip a large glass of water – or two. Not only will you quench your thirst, but you’ll feel better, too!
3. Diabetes. No matter how much you drink, you’re still thirsty! Being so thirsty that it feels like you can’t get enough water is a classic symptom of diabetes. The overabundance of sugar in your bloodstream draws water from the rest of your body, making you thirsty all the time. If you just can’t get enough to drink, talk to your doctor about your chances of diabetes, just to be on the safe side.
4. Diet. Sure, salty foods and spicy foods can make you thirsty, but even if you’ve cut out salt and go easy on the spice, you may still find yourself thirsty because of your diet! Some of the healthiest foods you can eat can also make you thirsty. Foods that are diuretics, like many vegetables and fruits, cause you to need to go to the bathroom more. The more you go to the bathroom, the thirstier you may end up. Don’t stop eating them, though. Just add healthy carbs, like oatmeal and brown rice, to your diet to help keep things in balance.
5. Dry mouth. While dry mouth may feel like thirst or dehydration, it’s actually a completely different condition from either of them. When your saliva glands stop producing as much saliva, you end up with dry mouth, as well as bad breath, irritated gum, change of taste, and even trouble chewing. And since it’s not caused by a lack of water, per se, drinking won’t resolve it. Usually dry mouth is a symptom of something else – a medication or another, underlying medical problem. If you’ve started a new medication, ask your health professional or pharmacist if it might cause dry mouth. Otherwise, mention it to your doctor.
6. Hormone imbalance. There’s a specific hormone imbalance called diabetes insipidus, but it has nothing to do with the blood sugar diabetes. Instead, it’s when the body doesn’t make enough of the hormone that helps your kidneys control the water in your body. Since the amount of water in your body is low, you end up so thirsty, all the time. Only your doctor can diagnose and treat this one, so make an appointment if your thirst isn’t going away.
7. Low blood pressure. Being thirsty is a lesser known symptom of low blood pressure, but it’s very real. Your body is trying to tell you to drink more so that you raise the level of water in your body – which in turn helps raise your blood pressure. Address the reasons your blood pressure is too low and you’ll address the reasons you’re thirsty.
Being thirsty all the time may just mean you need to drink more water. Start there.
But if it’s waking you up at night, or becoming a problem, don’t ignore it. Thirst is sometimes a sign of something else – something bigger.
So talk to your doctor and figure out why you’re always so thirsty.
