Nocturia (derived from Latin nox, night, and Greek [τα] ούρα, urine), also called nycturia (Greek νυκτουρία), is the need to get up in the night to urinate, thus interrupting sleep. Its occurrence is more frequent in pregnant women and in the elderly. Nocturia could result simply from too much liquid intake before going to bed (usually the case in the young), or it could be a symptom of a larger problem, such as sleep apnea, hyperparathyroidism, chronic renal failure, urinary incontinence, bladder infection, interstitial cystitis, diabetes, congestive heart failure, benign prostatic hyperplasia, ureteral pelvic junction obstruction, uterine fibroids, eating disorders, or prostate cancer.
