What is the term for excessive urination at night?

The term for excessive urination at night is nocturia. This condition is characterized by the need to wake up during the night to urinate, which can lead to sleep disturbances and reduced quality of life. Nocturia can be caused by various factors including age, certain medical conditions such as diabetes or heart failure, and lifestyle choices like fluid intake before bedtime.

Polyuria refers to the production of abnormally large volumes of urine, typically during the day. Anuria is the condition of producing no urine at all, which indicates severe kidney dysfunction. Oliguria is a reduced urine output, typically indicating a potential health issue but not specifically related to nighttime urination. Therefore, nocturia is the precise term describing excessive urination during the night.
