It is really shocking how little some primary care doctors know about the sleeve surgery. My original PCP still thinks that I had gastric bypass and was having issues with malabsorption and thought I couldn't take certain pills etc. and so wouldn't prescribe me antibiotics, etc. I tried to explain to him several times that I had had the sleeve surgery and not gastric bypass but it didn't seem to click. Finally I had to switch to another primary care doctor that understood.
I'm sure your PCP is a nice man but you are going to need someone who understands and empathizes with your surgery in case issues arise down the road.
