Nocturia is waking up one or more times during the night because of the need to urinate.
This means that if you wake up during the night — for instance because you are thirsty, hear noises, worry, or feel pain — and you decide to visit the toilet in the meantime, you do not have nocturia. You also do not suffer from nocturia if you go to the toilet first thing in the morning.
Waking up once in a while to urinate is common and is generally not very bothersome. However, if you regularly wake up two or more times a night, it can affect your quality of life and general health. The more times you wake up each night, the more it impacts your wellbeing.
