I used Keith McCormick and got my labs done through my PCP. He was helpful. He explained that he is not surprised that I have osteoporosis since I had Lyme for years and weighed under 120 pounds. The GI map was interesting. It found I had waaay to much ecoli, not enough hydrochloric acid, and I have inflammation and a gluten sensitivity. He wanted me to take Forteo, but my endocrinologist didn't want me to because it had a black box warning of cancer. He was unaware of that warning. I havd had cancer twice, and didn’t want again. I used Evenity instead, which also builds bone. Then Reclast which he and my endangered on. He can't come up with treatment notes and that is a problem. He doesn't speak with other Dr's. He is not good at responding via email that was how I was supposed to contact him. I had a question, but I didn’t get a response forv2 or 3 months. I just gave up on him, but I was very glad to have gotten his input and the results of the GI Map.
