Blood pressure medications--Losartan, for one

It's the same old broken record -- a doctor who thinks he is your boss rather than your adviser and partner. (He's also displaying a few signs of mild incompetence, but let that pass for the moment.) All of the above suggestions are good ones -- try to bring your PCP into the picture, or find a different endo, or both, etc. What you've experienced is an example of my #1 indictment of the medical profession. But don't feel singled out; you have plenty of company -- this kind of behavior is nauseatingly common. It took me some time, effort, and shopping around to find a doctor who doesn't treat patients like retarded children.
