Many people who have nocturia have simply developed a habit of waking up during the night to urinate.

Sometimes it is not the urge to go to the toilet that causes you to wake up but rather a restless leg syndrome, chronic pain, hot flashes or sleep apnea that might be the culprit in awakening you. Of course, once you are awake, you will feel the need to go to the toilet. Sometimes by treating those types of problems, you can even solve the nighttime urination issue as well.

If you have to go to the toilet more than twice during your six to eight hours of sleep, you may have a condition called nocturia.
