Normally, the amount of urine your body produces decreases at night. This allows most people to sleep 6 to 8 hours without having to urinate.

Some people wake up from sleep more often to urinate during the night. This can disrupt sleep cycles.


Drinking too much fluid during the evening can cause you to urinate more often during the night. Caffeine and alcohol after dinner can also lead to this problem.

Other common causes of urination at night include:

•             Infection of the bladder or urinary tract

•             Drinking a lot of alcohol, caffeine, or other fluids before bedtime

•             Enlarged prostate gland (benign prostatic hyperplasia, BPH)

•             Pregnancy

Other conditions that can lead to the problem include:

•             Chronic kidney failure

•             Diabetes

•             Drinking excessive amount of water

•             Heart failure

•             High blood calcium level

•             Certain medicines, including water pills (diuretics)

•             Diabetes insipidus

•             Swelling of the legs

Waking often during the night to urinate can also be linked to obstructive sleep apnea and other sleeping disorders. Nocturia (a condition that causes you to wake up during the night to pee) may go away when the sleeping problem is under control. Stress and restlessness can also cause you to wake up at night.
