Nocturia or Frequent Urination at Night







Nocturia causes sleep loss especially among elderly. It differs from bedwetting or enuresis, in which the person does not arouse from sleep, but the bladder empties anyway.

Most people can sleep for 6 to 8 hours without the need to urinate. One event per night is considered within normal limits; two or more events per night may be associated with daytime tiredness. Patients with severe nocturia may get up 5 or 6 times during the night to urinate.

The rectum or urinary bladder may prolapse as a result of changes in the integrity of connective tissue in the posterior or anterior vaginal walls, respectively, resulting in pelvic floor prolapse. Symptoms may include a feeling of pressure in the pelvis, or the visible protrusion of organs from the vagina. Prolapse is almost never painful, but the change in position of organs may cause urinary or bowel symptoms.

A diuretic is any substance that promotes diuresis, that is, the increased production of urine. This includes forced diuresis. There are several categories of diuretics. All diuretics increase the excretion of water from bodies, although each class does so in a distinct way. Alternatively, an antidiuretic such as vasopressin, or antidiuretic hormone, is an agent or drug which reduces the excretion of water in urine.

任何可以增加尿液量的藥物皆可稱為利尿劑(diuretic),其中也包括Forced diuresis。咖啡因、小紅莓汁和酒精都是效果較弱的利尿劑。利尿劑種類有很多,增加水分排泄的作用機理各不同。與之相對,也有抗利尿激素(血管加壓素)之類的降低尿量的抗利尿劑。

If you are experiencing nocturia, consult your doctor without delay and follow his/her suggested therapy. Keep a record of your sleep habits as well as any daytime fatigue experienced

After an initial evaluation, your doctor may prescribe medications, diagnostic testing including urinalysis, cystometry (a measurement of the pressure within the bladder), neurological tests (for some urgency problems), or ultrasound, or refer you to a sleep center for testing.
