I have been reading a lot about BPS and MUS theories lately. Not really because it affects me personally, but because I find these theories weirdly interesting and also a bit shocking to read. I thought it was interesting to look at other MUS categories, to see if we maybe could learn something about the way they are being handled. Apparently there is a lot of MUS around, like lower back pain and IBS. Both, in my eyes, perfectly treatable and organic problems. I thought IBS was a nice example to think about because there is a lot of ME/CFS people with IBS. I read this article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4692018/ It seems it has a lot of the same problems as in ME/CFS. There is a lot of research on the medical aspect. There is also a lot of research on the psychosocial aspect. It's probably a few different diseases, lumped together. There are a few nice strategies and medications for IBS (testing microbiome, FODMAP, antibiotics like rifaximine, neomycin), but nothing helps everyone if everyone is lumped in the IBS diagnosis. Apparently that is reason to reject the thought, instead of doing research on what makes these groups different. When I read this article, my only conclusion is: this is an organic problem. The conclusion of the article is: we can't call IBS a pure functional problem anymore. Why call it a functional problem at all? The evidence for the psychosocial factors as a cause is incredibly weak. IBS is actually a lot more simple than ME/CFS to make a solid theory, test it, make a protocol on specific testing and medication for gastrointestinal-specialists and actually help people, but people (doctors, insurance?) still want to hang on to the BPS-idea. So what does it take for something to become mainstream? When research comes up with an good organic explanation for ME/CFS, how can we make it mainstream as quickly as possible, not only available for the richer people who can actually afford private doctors. I'm actually pretty sure they will find a solution for ME/CFS soon, but I am really worried that it will take another 30 years before it becomes mainstream and people will actually be treated in their local hospital.
