What happens when women pee at night?

Female nocturnal urine increased at night, possible reasons: 1, pelvic floor organ prolapse, often seen in postmenopausal women or elderly women, pelvic floor muscle relaxation, resulting in bladder urethral depression, will lead to increased micturition resistance, bladder residual urine increased. Because there is always residual urine in the bladder, so patients always want to urinate, will show increased nocturnal urine. 2, bladder overactivity, the etiology is unknown, can show excessive frequent contraction of bladder detrusor muscle, leading to frequent urination phenomenon. But not accompanied by urgency, urinary pain symptoms, more obvious at night, there is no symptoms of storage period, the patient's bladder residual urine does not show increased phenomenon. 3, urinary system infection, such as acute urethritis, cystitis, can lead to increased frequency of urination at night, severe can lead to a few minutes of urination, each time the amount of urine is not much. This situation is often seen in acute infection, infection cured, and there will be no increase in the frequency of urination at night phenomenon.
