Do you always have to go? If you have a condition called polyuria, it’s because your body actually makes more pee than normal.
Adults usually make about 3 liters of urine per day. But with polyuria, you make more than that. In serious cases, some people make as much as 15 liters per day.
There are a few other conditions that make you need to pee more often, such as an overactive bladder, an enlarged prostate, and urinary tract infections. They can make you feel like you have to go all the time, even if there isn’t much in your bladder. But polyuria makes you have to go more often because your body actually makes more urine.
Because you need to go so often, you may also:
- Feel thirsty. You're losing a lot of fluid, and that can lead to dehydration.
- Wake up often at night. Your urge to go doesn't stop when you sleep.
The more fluids you drink, the more you’ll have go, of course. But there may be other reasons your bladder is always full:
Medicine. Some drugs can cause your body to make more urine. These include:
- Diuretics (water pills)
- SSRIs, a type of antidepressant
- Calcium channel blockers, which treat high blood pressure and chest pain
- The antibiotic tetracycline
Type 1 and Type 2 diabetes. Polyuria is often one of the first signs of diabetes. The condition makes sugar build up in your bloodstream. If your kidneys aren’t able to filter it out, it exits your body in your urine. As the extra sugar and fluids travel through your kidneys, you have to pee more. Plus, the more you go, the thirstier you feel, and the more you’ll drink.
Diabetes insipidus . With this rare condition, your body isn’t able to control its fluid levels. As a result, you feel very thirsty no matter how much you drink. You'll also have polyuria, which may get worse the more you drink to quench your thirst. Diabetes insipidus can happen because of kidney problems or an issue in the brain from surgery, a tumor, infection, or a head injury. It’s also a very rare complication of pregnancy.
How you stop polyuria depends on what’s causing it. For example, if you have diabetes that isn’t under control, you may need to make changes to your treatment program. If a medicine you take is the cause, talk to your doctor about switching to another drug or changing your dose.
If you’re worried about how much or how often you pee, talk to your doctor. She can help you figure out the cause.
