The average person urinates about 5 to 6 times a day, with a volume of about 200 to 300 ml each time. Among them, the number of urination at night is not more than 2 times. And more than this number of times is the manifestation of frequent urination. Frequent urination means that the frequency of a person feeling the urge to urinate increases significantly, of which the severe cases even reach a few minutes to urinate once. Infections, stones and tumors of the genitourinary system may cause frequent urination. This is due to inflammatory edema or decreased bladder tone, causing a decrease in bladder capacity. If the frequency of urination increases without decreasing or even increasing the amount of urine each time, it may be a physiological factor. Such as drinking more water, eating some diuretic food, or pathologic such as diabetes mellitus and other factors. To summarize, if there is an abnormality in urination, you should consult a doctor in time.
