He has been helpful and he can be dismissive. I feel like he might have a lot of patients and need to get on to his next meeting. At the same time he has said that I can call him if needed.

I'd just like to say that I'm on prescriptions that found 15 milligrams and I was having trouble with CVS and I did talk to the doctor about it. He did assure me that his staff was going to get a pre-approval because it did run out, I guess. And I don't know if that ever happened. I ended up calling my PCP and ended up getting it that way. So that's the only complaint they have. I just did not get a response on getting my description pre-approved through to CVS.

I have been seeing Dr Istfan for a year. Our meetings are the same message every time. He asks me the same questions- what are you eating and what are you exercising. When I tell him and add that this is not the issue, he tells me he does not know why I am not losing weight and recommends bariatric consults without digging deeper.

There was a lot of detail that needed to be explained about this operation and how to proceed going forward and it was done very well. That meant a lot to me.
