A friend was recently diagnosed as having high blood pressure and low blood pressure, have tried looking for more information via google but am having no luck. Can anyone help explain this?

is it ok to take high blood pressure,diabetics and heart medicine at the same time ,I take all medicine toggether and i was told doing so wont have medicine effect,is it true???
