Drink a lot of water but do not have urinal intention is what reason

If the patient drinks more water, but urinates less, it is considered to be caused by the following reasons: First, the patient's body fluid is lost through other aspects, so that the patient's urine is reduced, such as hot weather or intense exercise, excessive sweating, the patient's presence of more serious vomiting, or diarrhea, etc., will cause the loss of water in the patient's body, so that the patient's urine is reduced. Second, the patient may show obstructive diseases of the urinary system, such as hydronephrosis caused by ureteral stones, or urinary retention caused by prostatic hyperplasia or urethral stricture, which may cause the patient to show decreased urination frequency. Third, the patient has more serious renal diseases, such as renal failure, which will cause renal filtration to stop or decrease, so that the patient's urine production will decrease. The above are some specific reasons why the patient drinks a lot of water but does not urinate. It is suggested that the patient should go to a regular hospital for examination and treatment.
