Doctors emphasize that nocturia itself is not a disease but a symptom. Identifying its cause is key to managing it effectively.

What Causes Nocturia?
Nocturia can result from a wide range of factors, including lifestyle habits, hormonal changes, and medical conditions.

Common causes include:
Drinking large amounts of fluids before bedtime

Consuming caffeine or alcohol in the evening

Eating foods with high water content late at night

Certain medications, especially diuretics

Sleep disorders such as sleep apnea

The role of antidiuretic hormone (ADH)
A key factor in nighttime urination is antidiuretic hormone (ADH). This hormone helps the kidneys reduce urine production during sleep. As people age, ADH production often decreases, leading to increased urine output at night.
