I assume you mean you are having some incontinence
, where you are letting out small amounts of urine
when you do not intend to.
This can have many causes, but just drinking water or too much water isn't a cause, its just unmasking the problem. You need to see your pcp, ob/gyn or a urologist if its a problem. If you have had childbirth, this is a common cause, but there are many others.
