Why do women urinate frequently?

What causes frequent urination in women?

(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.
