If it happens more than once a night, your doctor might call it nocturia. It tends to happen more as you get older. This may be due to illness, like diabetes, heart failure, or to infection, inflammation, and other age-related bladder problems. It may help to avoid caffeine and alcohol later in the day. Your doctor may prescribe water pills (diuretics) to help you pee earlier in the day, or other drugs that lessen the need to go.
