It is common to experience frequent urination, particularly at night, when getting older because the body tends to create a lower number of the antidiuretic hormone responsible for retaining fluid, explains Healthline. Moreover, the body finds it hard to store urine in the bladder for a longer period due to weakening of the bladder muscles over the years.
Nighttime urination sometimes indicates an underlying cause, such as diabetes, congestive heart failure or chronic kidney failure, according to Healthline. An enlarged prostate and sleep disorders are other possible causes.
Doctors diagnose the cause of nighttime urination by assessing a person's symptoms, conducting a physical examination, and asking questions about the frequency of urinating at night, length of time the problem has occurred and typical activities before sleeping, notes Healthline. They also order urinalysis procedures, urine concentrations and other diagnostic tests. Treatment for nighttime urination involves limiting fluid consumption at night, napping in the afternoon, elevating the legs, or using compression stockings to improve blood flow. Doctors sometimes prescribe anticholinergics, especially if an individual also experiences bed-wetting.Learn more about Pain & Symptoms
