Bad kidneys are not the cause of frequent urination. There are many reasons for frequent urination, such as overactive bladder and urinary tract infection, which are most common in women; prostatitis and urinary tract inflammation are most common in male patients, and these factors can lead to frequent urination, mainly because the bladder mucosa is stimulated by inflammation, the bladder will contract, and the bladder’s urine storage function will be in an unstable condition, and it will keep urinating. Patients with overactive bladder disorder can be relieved from urinary frequency by taking oral M-receptor antagonists. Patients with urinary tract infections can also be relieved from frequent urination by taking oral anti-inflammatory drugs. Patients with prostatitis must actively treat prostatitis to reduce the congestion and edema of the prostate, and they will be able to relieve the frequency of urination. A bad kidney will only lead to a reduction in the amount of urine formed, but not to frequent urination.
