What is Nocturia?

Nocturia is a condition where a person awakens numerous times during sleep to urinate, often disrupting sleep cycles. Most people can sleep six to eight hours a night without having to go to the bathroom because the bladder can hold more than a half liter of urine. However, people with nocturia are incapable of holding this much urine without feeling the need to urinate and, therefore, wake up throughout the night with urges to use the bathroom.

Nocturia as a Symptom

Nocturia is often a result of other medical conditions, including:

  • urinary tract infections
  • overactive bladder (OAB)
  • renal failure
  • congestive heart failure
  • diabetes insipidus
  • diabetes mellitus
  • cystitis
  • benign hyperplasia of the prostate
  • high blood-calcium level

Nocturia as a Side Effect

Certain medications can also increase the occurrence of nocturia:

  • diuretics
  • lithium
  • demeclocycline
  • methoxyflurane
  • phenytoin
  • propoxyphene

However, nocturia can simply be caused by drinking too many liquids before going to bed. Caffeinated and alcoholic beverages can exacerbate the problem. 

Your doctor can conduct simple blood and urine tests to determine the root cause of nocturia.
