Why do men urinate more? Or it may be related to this matter

Generally speaking, if men do not drink a lot of water, they will not urinate very often. In the hot summer, they may only defecate two or three times a day due to sweating. However, many men defecate very frequently and urinate a lot. Why is this?

(1) Increased urine volume:

When the 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, have a large amount of urine and urinate frequently, but they do not feel any discomfort when urinating.

(2) Inflammatory triggers:

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 male genital capitis in children, vulvitis, etc. can also cause frequent urination. Under the stimulation of inflammation, frequent urination, urgency, and urinary incontinence often occur at the same time, which is called urinary tract irritation syndrome, commonly known as "tri-urinary syndrome".

(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, etc. 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 triggers:

Such as urinary tract stones and foreign bodies, usually with frequent urination as the main manifestation.

(5) Reduced bladder capacity:

Such as bladder space-occupying lesions, tuberculous bladder contractions or larger bladder stones.

(6) Psychoneural diseases:

Frequent urination occurs only during the day or before going to sleep at night, often due to nervousness or hysteria. It may also be accompanied by urinary urgency and nausea.
