Why do I urinate more at night?

Humans have three urgent needs. When people feel the urge to urinate, they must urinate in time to avoid damage to the body caused by holding urine. But did you know that the number of times a person urinates is roughly the same? If it exceeds this number, it is generally called frequent urination. However, people who truly have frequent urination do not distinguish between night and day. If you only have frequent urination at night, it is very likely caused by other reasons. So why do you urinate more at night?

Normal adult

The average urination time during the day is 4 to 6 times, and 0 to 2 times at night after going to bed; infants urinate 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.

Causes

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 filtering function 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 they do not feel any discomfort when urinating.

2. Inflammatory stimulation: When there is inflammation in the bladder, the urinary center is in an excited state, resulting in frequent urination and reduced urine volume. 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, and vulvitis 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 syndrome, commonly known as "triuria".

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

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

5. Psychoneural frequent urination: Frequent urination only occurs during the day or before falling asleep at night. It is often caused by mental tension or occurs in patients with hysteria. This may also be accompanied by urinary urgency and pain.

Through the analysis in this article, you should have a clear understanding of why you urinate frequently at night. It is recommended that you start to prevent frequent urination at night from the details of your life. In normal times, pay attention to controlling your salt intake and eat more foods high in potassium, such as mushrooms, legumes, peanuts, walnuts, etc.
