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, through the regulation of the kidney, the urine volume increases, the frequency of urination also increases, and frequent urination occurs. Under pathological conditions, such as some patients with diabetes and diabetes insipidus who drink a lot of water, have a large urine volume, and urinate frequently, but 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 acute cystitis and tuberculous cystitis. Other diseases such as prostatitis, urethritis, pyelonephritis, chronic penile capitis 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, commonly known as "triple urinary syndrome".

(3) Dysuria of urination 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 aseptic "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 tract stones and foreign bodies, usually presents with frequent urination.

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

In addition, if a man has mental and neurological factors, he will also develop symptoms of frequent urination. At this time, the problem of frequent urination is only seen during the day. Of course, some people also have different degrees of frequent urination before going to bed at night. People who are nervous are more likely to have frequent urination. And hysterical patients will also have urgent and painful urination.
