What causes frequent urination? Different causes for different people

Frequent urination is an extremely common problem that can happen to anyone. This disease can be physiological or non-physiological. The physiological one is directly related to drinking plenty of water, while the non-physiological one is inseparable from inflammation and getting angry. Therefore, in order to treat it, we must understand the cause of the frequent urination in order to see the treatment effect.

1. Frequent urination in men

(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 amount of urine increases through the regulation 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 the bladder is inflamed, 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) Urinary dysfunction: Certain factors, such as prostatitis, can cause excessive contraction of the urethral sphincter, leading to bladder outlet obstruction and residual urine formation, causing urine to flow back into the prostate, which can not only bring in pathogens but also directly stimulate the prostate, inducing sterile "chemical prostatitis", causing abnormal urination and pelvic pain. Many patients with prostatitis have a variety of urodynamic changes, such as decreased urine flow rate, functional urinary tract obstruction, detrusor-urethral sphincter dyssynergia, etc.

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

(5) Reduced bladder capacity, such as bladder space-occupying lesions, tuberculous bladder contracture, or large bladder stones.

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

2. Frequent urination in women

There are many reasons for frequent urination in women, mainly including reduced bladder capacity, such as bladder space-occupying lesions, compression from the enlarged uterus during pregnancy, tuberculous bladder contracture, or large bladder stones.

(1) Psychoneural factors. Frequent urination caused by mental factors usually manifests as frequent urination at times and frequent urination at times, with obvious "signs" of mental effects. Frequent urination caused by mental stress will not cause serious consequences to your health. For those whose frequent urination affects their study, work, and rest, psychological therapy and nerve-regulating drug treatment can be performed. Especially for some long-term and severe frequent urination, relevant examinations should be carried out carefully, and the frequent urination should not be easily diagnosed as caused by psychoneurological reasons.

(2) Non-inflammatory irritation, such as urinary stones, foreign bodies, etc.

(3) Inflammatory stimulation. Acute cystitis, tuberculous cystitis, urethritis, pyelonephritis, prostatitis, vulvitis, etc. may also be the cause of frequent urination. Under the stimulation of inflammation, frequent urination, urgency and pain may occur at the same time, which is called urinary tract irritation syndrome.

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

3. Frequent urination in children

(1) Bad habits: Some parents often hold their children to urinate when they are very young, which can easily lead to the habit of urinating before the bladder is full. Over time, this will result in the urge to urinate even when the bladder is full with only a small amount of urine.

(2) Foreskin is too long or phimosis: Boys may have frequent urination due to urine residue in the foreskin sac irritating the urethra.

(3) Urinary tract infection: In addition to frequent urination, there is pain during urination and sometimes fever.

(4) Psychological factors: Some children may wet the bed occasionally and be blamed for it. They may then worry about wetting the bed again and start to urinate frequently.

(5) Pinworm disease: Pinworms crawl into the urethra, causing frequent urination, which is more common in girls.
