Generally speaking, men’s frequent urination may be caused by physiological and pathological reasons, such as alcohol consumption, cystitis, prostatitis, bladder occupational lesions and so on. 1. Physiological reasons: if you drink a lot of water or drink a lot of beer at night, when you lie down to sleep, the beer and water will be metabolized by the kidneys into urine and excreted, which is a physiological phenomenon and usually does not require treatment. 2. Pathological causes: There are many pathological causes, including cystitis, prostatitis, bladder occupational lesions and so on. (1) Cystitis: It is an infection of the bladder mucosa. It may be caused by bacterial, viral and other pathogenic bacteria infection, or it may be caused by upward or downward infection. Due to the stimulation of its inflammation, symptoms such as frequent urination, urinary urgency and painful urination can occur. (2) Prostatitis: when the prostate is infected by pathogens, inflammation occurs leading to congestion and edema of the prostate, which stimulates the bladder neck area, there may be frequent, urgent and painful urination. (3) Bladder occupying lesion: it may be due to tumor, sarcoma and other causes of bladder occupying, because the position in the bladder is occupied by other substances, so the urine storage will become less, thus the phenomenon of frequent urination. In addition, male urinary frequency can also be seen in other pathological reasons, it is recommended that patients go to the regular hospital to do relevant examinations in time, and follow the doctor’s instructions for treatment.
