I googled Vit D and eds last night, I can't find any papers or medical jouranls which talk about it. I found plenty of sites where individuals had posted they had eds and low levels of vit D ? low absorption of vit d, but nothing official. I did also find a website, run by a vit supplement company claiming vit d supplements could cure eds
...wish there was somewhere one could report such places!
Bearing this in mind we do know that gastro issues are related, and so it is no great leap to suppose that some absorption issues may be present.
Bizzey as far as I am aware they can not do a blood test which is related to collagen....so I wonder what they are testing for? They tested ds for a variety of things, full blodd count, inflamatory markers, thyroid, coeliac disease and other bits and bobs, mainly to rule out other factors for his weight loss. Everything came back normal, so they decided his weight lose was pain related.
Having said that he has stabilied and even put some on in the last year, so that is good.
THC - my ds has an nhs clinical psychologist. He has real issues with avoidance tactics, and refusing to communicate with drs, and is quite depressed about pain levels, and limitations due to eds. It was only a year ago he was talking about suicide, and he is much better than that now, but he still has his moments. GOSH service is probably exactly what ds needs and he is what it was designed for, pure eds hypermobile type ....etc....used to think it is a shame he couldn't get there due to our crap (sorry ladies) rheumie, but the more I read about your experiences, I think lucky escape. If they tried to insist I was not present during sessions, ds would have an absolute meltdown or monumental proportions.
