Nocturia is a medical term to define a disorder in the body, when the night urine production prevails over the day one. Normally, a healthy body produces twice as less urine in the nighttime as in the daytime. This allows us to sleep uninterruptedly for several hours to let the body relax. Waking up once a night to do a bathroom trip is considered to be a norm. If a person is disturbed two or more times, it may be a sign of nocturia, that requires medical attention.

Although nocturia develops in people of different ages, it is most commonly seen in adults aged 60 or older. There are numerous reasons that can eventually lead to nocturia: from everyday habits and lifestyle to serious diseases in the body.

A healthy person can develop nocturia as a result of excessive consumption of caffeine-containing beverages, especially in the evening. Tea, coffee, and alcoholic drinks have a visible diuretic effect. Sometimes people experience nocturia just because they have developed a habit to wake up to urinate during the night.


Nocturia may occur as a symptom of a disease or several diseases in the body. For example, diabetes mellitus, hepatic or cardiac failure can eventually lead to frequent nighttime urination. Prostate enlargement in men interferes with normal urination too. Nocturia can signal hyperactivity of the bladder or reduced bladder capacity. A course of treatment with certain drugs can also result in nocturia as a side effect, especially if you are taking diuretic pills to treat high blood pressure.

Since nocturia is accompanied by regular sleep disturbances, a person may feel lack of sleep. This results in low energy, fatigue, decreased performance at work, mood disturbances, etc.

Diagnosing nocturia involves general examination and tests to rule out other diseases, that might cause the dysfunction. The doctor will need detailed information about the frequency of urination at night, your diet and eating habits as well as your lifestyle.

If you think that you have the symptoms of nocturia, it is important to visit a doctor as soon as possible to prevent aggravation of the disease.
