Hi Cstar,
Do you know for sure that your Dad does not have urinary urgency or frequency on these numerous trips to the BR?? Its very common for middle age men to have this and can be a sign of prostrate problems, I would mention this to his doc and ask him to order a simple PSA blood test, it checks the function of the prostrate for abnormailties or enlargement. It can for sure rule out any medical reason for the frequent BR trips, good luck with Dad,
