How many times is it normal to urinate at night?

Many people have the symptom of frequent urination at night. Moreover, patients often have various uncomfortable symptoms caused by frequent urination. Moreover, some people often find it difficult to get up at night, especially in winter. Most people are even worried that they have problems of one kind or another. How many times is it normal to urinate at night?

Urinary frequency refers to increased frequency of urination. A normal adult urinates an average of 4 to 6 times a day during the day and 0 to 2 times at night after going to bed; an infant urinates 20 to 30 times during the day and night. If the frequency of urination increases significantly and exceeds the above range, it is frequent urination. There are many reasons for frequent urination, which can be summarized as follows:

(1) Increased urine volume: When urine volume increases, the frequency of urination will also increase accordingly. Under physiological conditions, such as drinking a lot of water, eating watermelon, and drinking beer, due to the increase in water intake, the urine volume increases through the regulation and filtration of the kidneys, and the frequency of urination also increases, resulting in frequent urination. Under pathological conditions, such as some patients with diabetes and diabetes insipidus, they drink a lot of water, urinate a lot, and urinate frequently. But there was no discomfort in urination.

(2) Inflammatory stimulation: When there is inflammation in the bladder, the nerve perception threshold is lowered, the urinary center is in an excited state, resulting in frequent urination and reduced urine volume (<300-500 ml/time in adults). Therefore, frequent urination is an important symptom of cystitis, especially in acute cystitis and tuberculous cystitis. Other conditions such as prostatitis, urethritis, pyelonephritis, chronic balanoposthitis in children, vulvitis, etc. can also cause frequent urination. Under the stimulation of inflammation, frequent urination, urgency and pain often occur at the same time, which is called urinary tract irritation sign, commonly known as "triuria sign".

(3) Non-inflammatory irritation: such as urinary stones and foreign bodies, usually with frequent urination as the main manifestation.

(4) Decreased bladder capacity: such as bladder space-occupying lesions, compression from the enlarged uterus during pregnancy, tuberculous bladder contracture, or large bladder stones.
