What can cause frequent urination?

  Frequent urination is a symptom of many urological diseases. Some people blindly use antibiotics orally and infusions due to lack of knowledge or avoidance of medical treatment, which not only delays the diagnosis and treatment of the disease, but also causes economic and physical losses. I found in my clinical work that some patients are not even sure what exactly is considered frequent urination. In fact, the so-called frequent urination is simply explained as an abnormal increase in the number of urination.  Normal adults urinate 4 to 5 times during the day and 0 to 1 time at night, with a volume of about 300ml each time. If, with a normal diet, you urinate >8 times during the day, with a volume of <200ml each time; or if you urinate 2 times and more at night, you can be diagnosed with frequent urination. There are two types of frequent urination: the first one is: the total urine volume increases, but the volume of urine does not decrease each time. The second one is: the total urine volume remains the same, but the volume of each urine is reduced due to the reduction of bladder capacity. The former is seen in diabetes mellitus, uremia, aldosteronism, and polyuria in acute renal failure.  The latter is seen in: 1. Cystitis. Frequent urination due to bladder mucosa congestion, edema, inflammatory infiltration, superficial ulceration, and irritation of the bladder. Urinary frequency is combined with urinary urgency and painful urination as bladder irritation symptoms. In tuberculous cystitis, symptoms such as urinary frequency last for a long time. When the tuberculosis lesion invades the muscle layer and causes extensive fibrous tissue hyperplasia, bladder contracture can occur, reducing bladder capacity and increasing urinary frequency and even urinary incontinence. If the cystitis is not cured for a long time, you should be especially careful of the possibility of having tuberculous cystitis, interstitial cystitis, and adenoidal cystitis.  2, prostate enlargement caused by urinary obstruction. The prostate is located at the outlet of the bladder. When the enlarged prostate presses the urethra at the outlet of the bladder, it will not only cause poor urination and difficulty in urination, but also increase the amount of residual urine (urine that cannot be fully discharged each time you urinate) and reduce the effective capacity of the bladder and cause frequent urination.  3, neurogenic bladder. Due to lesions of the central and peripheral nerves themselves (such as brain tumors, Parkinson's disease, spinal cord lesions), or others due to trauma, certain chronic diseases (such as diabetes, cancer invasion, compression of nerve tissue), can lead to the normal physiological function of the nerve pathways that control urination is affected, so that the bladder forced urinary muscle (the muscle that makes the bladder contract) reflexes are hyperactive, causing urinary frequency or urge incontinence.  4, lesions of organs near the bladder. Such as appendicitis, pelvic abscess, lower ureteral stones stimulate the bladder or pregnant uterus, uterine fibroids, uterine prolapse compress the bladder, so that its effective capacity is reduced and cause frequent urination.  5, mental tension, anxiety and fear can increase the number of urination. In addition, circumcision, penile head prepuce, urethritis, prostatitis, etc. can cause frequent urination.  The above is my summary of the main causes of frequent urination, if you have the symptoms of frequent urination, it is best to go to a regular public hospital to seek proper diagnosis and treatment. Of course, as a male urologist, I am also willing to serve you wholeheartedly.
