What causes frequent urination?

A normal adult usually urinates 4-6 times a day. If the frequency is higher than this, it means that the urination frequency is too high. We need to pay enough attention to it. There are many reasons that can cause frequent urination. The most common one is male prostatitis. If a man suffers from prostatitis, it will cause inflammation in the bladder area, so he will have the urge to urinate frequently and need to go to the toilet often. So, what is the reason for frequent urination?

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) Inflammation stimulates the bladder. When the bladder is inflamed, the urinary urge 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) Certain factors of urinary dysfunction, 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 presents with frequent urination.

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

(6) Psychoneural urinary frequency 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 is usually caused by psychogenic factors, with the symptoms of frequent urination sometimes more and sometimes less, and there are 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, 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 due to space-occupying lesions in the bladder, 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 bladder feeling the urge to urinate even when there is only a small amount of urine.

(2) Boys with phimosis or foreskin that is too long may experience frequent urination due to urine residue in the foreskin sac irritating the urethra.

(3) Urinary tract infection not only causes frequent urination, but also pain during urination and sometimes fever.

(4) Psychological factors: Some children may wet the bed occasionally and then be blamed. They may worry that they will wet the bed again in the future, so they urinate frequently.

(5) Pinworms cause frequent urination when pinworms crawl into the urethra, and are more common in girls.
