Generally speaking, there is nothing wrong with wanting to go to the toilet half an hour to forty minutes after drinking water, it is a normal phenomenon. In addition, the time between drinking and peeing is often affected by external factors, such as weather, excessive heat or cold, or strenuous exercise, which can affect the time between urination. If this is the case since childhood, it may be caused by a congenital small bladder or a loose bladder sphincter. If this happens only recently, it is caused by inflammation of the prostate, contusion, cystitis, etc. You should go to the urology department of the hospital for examination, and identify the specific cause by choosing tests such as urine routine analysis, prostate fluid culture and drug sensitivity test, and give targeted treatment such as anti-infection. Accompanied by irritable thirst, apparently high urine volume and high water consumption, the possibility of urolithiasis should also be considered. If necessary, blood and urine osmolality measurement and water-fastening-augmentin test can be performed, which can often clarify the diagnosis of urolithiasis and help assess the degree and classification of urolithiasis. In summary, the urge to urinate when drinking water is not necessarily a disease, it may be caused by factors such as mental weather, but it is necessary to exclude diabetes, urolithiasis or urinary tract infections.
