Nocturia (erived from Latin nox, night, and Greek [τα] ούρα, urine), also called nycturia (Greek νυκτουρία), is the need to get up during the night in order to urinate, thus interrupting sleep. Its occurrence is more frequent 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, Interstitial Cystitis, diabetes, benign prostatic hyperplasia, Ureteral Pelvic Junction Obstruction or prostate cancer.
