Nocturia is the urgency to interrupt sleep for urinating. One (1) episode of nocturia per night is considered to be within normal limits.

It should be pointed out that:

• Nocturia is a common symptom in both men and women and increases with age.
• Nocturia may be disturbing and cause sleep disorders with significant effect on the patient's quality of life.
• Nocturia is a symptom, not a diagnosis.
• Nocturia has to be evaluated by the physician for identifying the deeper causes that are associated with it (e.g. diabetes mellitus or prostate hypertrophy).
