I have some left over phentermine from about a year ago, can anyone see why it would be bad to take those with the pre-op diet? It does help with the not feelig hungry and I never had issues with it before, it's just that I didn't feel like I was doing a good enough job of watching what I ate when I took them and stopped.

It can affect your liver because of the things they put in it and ur liver can be too fatty which means they may not be able to do your sleeve.

I mentioned to my doctor that I had taken phentermine in the past and he asked if I was still taking it. I told him I wasn't, and he said if I had been I would need to stop immediately. That was something he told me a few months before my surgery.

If he said that then I would stop to be on the safe side

I was on phentermine for my metabolism on a schedule that was intended to help keep my metabolism shook up. The on-again period kicked in and went up to 3 days from surgery.

My doctor said it was ok, but I had to keep a very careful eye on my blood pressure and heart rate. If I had too elevated pressure it could have caused issues.

I have never heard of it preventing the reduction of fat in the liver, no offense to any previous posters. It is often prescribed to people who need to eat less in an attempt to ease the liver's size.

I believe that those pills make your heart beat faster and possibly put more stress on it. I wouldn't want to take a chance on it....

I was told to stop taking them about a month prior to surgery. The pills go affect your blood pressure and heart rate. My PCP advised me to stop them when she did my physical for my pre op, way before my surgeon even got around to it. So you might want to look into that before you start taking them.

OK, sounds good. I sure don't want anything to mess up the surgery! Really thrilled with it all and want to do it right!

Yes, my surgeon and anesthesiologist said I had to be off the phentermine for at least 30 days, because of the whole heart rate thing. I would say to avoid it just to be on the safe side.
