Nocturia is a symptom, not a disease, in which people wake up several times during the night with the need to urinate—at least two or three times.
It is common after the age of 50, although occasionally people can suffer from it before. It affects more men than women; out of ten people affected, only three are women. These people wake up feeling that they have to urinate, get up, go to the bathroom and then go back to bed. The symptom, therefore, has nothing to do with enuresis or uncontrolled bed wetting, since those affected by nocturia have urinary control.
