Hi! Many things could cause it but if there aren't any more symptoms than that i.e. you need to urinate very often,you have scant urine, it's cloudy or discolored, a burning sensation when you go, false sense of needing to go, then you probably just aren't drinking enough water.Or like others have pointed out, some foods leave a lingering stench in your urine.If you have some of the symptoms I listed, it's best to go to the Dr. for a checkup-okay? Good luck
