busgrw- yes, there are many names for these types of doctors and you need to do your research but here are some words you can google

here are some luminaries in the US, take a look at the websites so you know the general idea
mark hyman
http://drhyman.com/ he has written some great books
http://clearcenterofhealth.com/ this is where i go, as you can see they have various practitioners and combine modalities- chinese medicine, M.D.s, osteopaths, etc.
here's a place in San Fran
http://www.sfpmg.com/a good place should either have many methods available, like a collective of healers, or if it's just one doctor, they should offer full blood testing, nutrient testing, hormone panels, etc. they will have extensive knowledge of autoimmune conditions, food allergies, and hormonal imbalances.
it should be very professional and they will take time to answer your questions, this is NOT like the typical medical establishment that treats people like fools. these doctors are educators and generally use nutrition and nutritional supplements to heal, along with hormones if necessary and other adjunctive methods such as chiropractic, acupuncture, exercise, etc for whatever is needed.. sometimes the techniques are very cutting edge and "weird" to the general uneducated public.
