Frequent urination refers to an increase in the frequency of urination. Normal adults urinate an average of 4 6 times a day during the day and 0 2 times at night after bedtime; Babies urinate 20 to 30 times a day and night. If the frequency of urination increases significantly, beyond the above range, it is called frequent urination.

There are many causes of frequent urination, which can be summarized as follows:

1) Increased urine output: When urine output 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, through the regulation and filtration of the kidneys, the urine output increases, and the frequency of urination also increases, and frequent urination occurs.

In pathological cases, such as some patients with diabetes mellitus and diabetes insipidus, drink more water, have more urine output, and urinate more often. However, there was no discomfort during urination.

2) Inflammatory stimulation: When there is inflammation in the bladder, the neurosensory threshold is reduced, the urinary center is in a state of excitement, resulting in frequent urination and a decrease in urine output (300 500 ml times for adults). Therefore, frequent urination is an important symptom of cystitis, especially acute cystitis and tuberculous cystitis.

Others, such as prostatitis, urethritis, pyelonephritis, pediatric chronic penile forehitis, vulvitis, etc., can cause frequent urination. Under the stimulation of inflammation, urinary frequency, urgency, and painful urination often occur at the same time, which is called urinary tract irritation, commonly known as "triple urine sign".

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

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

5) Psychoneuropathic frequent urination: Frequent urination is only seen during the day, or before falling asleep at night, and is often nervous or seen in patients with hysteria. At this time, it may also be accompanied by urgency and pain.
