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.
