A normal person should urinate 5-6 times a day. A normal person urinates 5-6 times a day, 300-500 ml each time, and the amount of urine in a day is probably between 1500-2500 ml. For people who drink more water, the amount of urine will also increase appropriately. If the daily urine volume is 500-1000 ml more than normal for polyuria, the patient may have kidney disease, such as nephritis or nephrotic syndrome, cystitis, urinary tract infection, etc. Patients with early diabetes also have symptoms of polyuria, so this condition requires a laboratory test of blood sugar and kidney function and urinary routine to see if there are any abnormalities. Some elderly people with cystitis or prostatitis or prostate enlargement may also experience an increase in the number of urination, which is not a lot of urine each time, and some may also experience urine dripping. In short, when pathological increased urination occurs, you need to promptly consult a urologist. In addition, patients should try to avoid drinking water before going to bed, which will increase the number of urination while affecting the quality of sleep, which is not worth the loss.
