Nocturia: focus on etiology and consequences.

Nocturia is a condition characterized by the need to awaken ≥ 1 times per night to void. Although nocturia is a multifactorial condition that can coexist with other lower urinary tract symptoms, the most common causal factor is nighttime overproduction of urine. Many people with nocturia do not seek help, accepting it as a natural consequence of aging. However, nocturia is common in men and women of all ages and has a profound impact on quality of life, especially in the young, that may be associated with increased morbidity and mortality. Nocturia as a condition deserves public health attention.
