I also have EDS and just recently found out that I have a vitamin D deficiency so I'm taking 4 vitamins 3 times a day to help. The lack Vit D somehow can interfere with the iron in your blood and if you have low iron then you'll faint a lot. I used to black out a lot when I was younger but I've learned to tell when it's coming and lay down before it happens. This is something you all may want to check as well. Not sure if it goes with the EDS though.
I too have very hypermobile joints. My biggest problem is my joints. I've had hip and knee surgery; doctors suggested surgery for elbows that are dislocated at all times at radial head; and all other joints will dislocate or sublux should I say at nothing. I've dislocated my wrist picking up a piece of paper and dislocated my foot, hip and knee by rolling over in bed with my foot barely caught in the sheet.
I agree with watertester we tend to have to educate the docs about EDS as they usually have barely even heard of it much less know anything about it. Frustrating part for me is that there's no test to say for sure if it's actually EDS or something else. I had the biopsy done and it still was inconclusive so they just said we'll stick with EDS since it's the closest diagnosis we have!
But the main thing about having EDS is attitude. If you don't keep a positive attitude then you'll let it drag you way down and that's the last thing we need is to add something else to the laundry list that goes along with having EDS! So stay positive.
Take care and God Bless you all.
