You can get this from a PCP. Unfortunately you have to advocate HARD. I am seeing a resident at Boston Medical Center primary care who is sending me to any specialist I request. Does BMC take your insurance? DM me if you want her name.

They don’t offer testing that is FDA approved so what you get from them ends up being a fake diagnosis, supported by non evidence based tests, and $300-400 for supplements that you don’t need, that make your urine expensive and you still feel like shit.

I worked in primary care and GI and all functional medicine practitioners are people who prey on people who don’t feel well. I had one patient who was taking, and I’m not being dramatic, 47! supplements a day for acid reflux. And guess what? She was significantly poorer and still had reflux.

Try a nutritionist?
