Prostatitis frequent urination at 4~6 pm every day may be caused by concentrating on drinking water at one time or forming a habit of urination. The typical symptoms of patients with prostatitis are urinary symptoms such as frequent urination, urinary urgency, painful urination, etc. If the patient has frequent urination symptoms at 4-6 pm every day, it may be due to the patient’s habit of drinking water at a fixed time in the afternoon every day, and when the amount of water consumed is relatively large, it will naturally lead to an increase in the amount of urination and the number of times urination occurs. It may also be that the patient has formed the habit of urinating at 4 to 6 p.m. every day, thus generating a psychological suggestion that he wants to urinate as long as he drinks a little bit of water. The majority of the regular time period of frequent urination is caused by habit, itself prostatitis usually does not cause frequent urination at a fixed time, but persistent. It is recommended that patients seek medical attention in time for standardized treatment.
