As the title suggests, are they worthwhile? Or am I better off not wasting more money?
I don't find much to value in functional medicine.
If there may be objective things that functional medicine can find like mold,heavy metals,gene defects/mutations,sibo,lyme, there may be some value.
The problem is that they're not necessarily objective. See 5 different LLMDs and get 5 different diagnoses (depending on their favorite labs) and none of the labs have independent validation studies. Same with mold, SIBO, etc.
Functional medicine doctors are useful if you're not familiar with the subject, though. Before I read all the CFS books, lyme books, CIRS theories, etc - then functional medicine doctors might have been useful. If you haven't heard of d-ribose, Q10, carnitine, methylation, and so on, then it could be useful. If you've tried all those things numerous times and in numerous combinations, then a functional medicine doctor is mostly just useful if you're trying to get a specific RX you think might be helpful.
Just my own personal experience, YMMV.
It seems like there may be valuable information in there, but I've found most of the protocols aimed at targeting those variations seem to give temporary benefits at best.
Some of the treatments may have worked for some unrelated reason.
I have looked at all the various genetic information (V158M, 677T, etc). It seems like there may be valuable information in there, but I've found most of the protocols aimed at targeting those variations seem to give temporary benefits at best. Others are incredibly complex and require levels of testing that would certainly do me more damage than good.
Terrific run-down on both allopathic and functional medicine, @wabi-sabi ....Maybe others have had more positive experiences.
When you say damage,do you mean financially?
