Auto immune diseases are all untreatable and severely reduce quality of life in some cases. One thing proven to slow their progress is stress reduction.
As you can imagine, being less stressed is really hard when you have a chronic illness. This is exacerbated by doctors ignoring you. Having anyone spend an hour to help you in any way is such a relief. I wouldn't be surprised if this played a large role.
As another example, my wife and I have had six miscarriages. We're 25 and both healthy and the many doctors we've seen agree. Well if the doctors don't have a diagnosis, they don't wanna see you.
When it comes to recurrent miscarriage, there is no treatment. They suspect there are likely auto immune diseases we don't know about. Indeed, this seems likely. Most studies on potential treatments cannot be reliably replicated. The only thing that has been shown to reduce miscarriage risk in future pregnancies is tender loving care-- having a doctor who will talk with you for hours whenever you want, and being taken care of.
So now we see a new matronly obstetrician. She's a bit quirky but we feel like she won't abandon us like the other doctors did. Her appointments are multiple hours long, and she's happy being paged in the middle of the night when we've found out we're pregnant again. At 5 am when you find out you're pregnant after five miscarriages, nothing is more calming than a soothing voice on the telephone
This doctor has also encouraged us to seek out alternate practitioners, like acupuncturists and massage. She doesn't believe in their treatments working per se (she's an md and is happy providing real treatments), but I think she understands they these practitioners will at least make you feel calm and taken care of. Whereas I used to laugh at people who would see them before, I get it now.
When you have a medical condition that is chronic and there's no end in sight and no cure available, you need a friend more than a doctor, and unfortunately, there's not much overlap between the two
