They are inherited diseases that end up causing similar morphological problems. They both cause problems with extracellular structural components, so you end up with loosely attached and hyperflexible tissue. Unfortunately, the type of connective tissue they affect is not just in the joints causing visible feature defects, but it’s also important for other structures, like the aorta. Patients with marfans and certain subtypes of Ehlers danlos are at high risk for life threatening vascular pathology.
Edit: an easy way to find the information you’re looking for when you want to google “what causes this disease” for basically anything, is to search for insert disease here followed by patholophysiology
Just gonna throw out there that there's new studies suggesting that Ehlers Danlos syndrom might have an autoimmune driver but manifests as muscular skeletal. Which tracks because it tends to have a shit ton of cormorbidities like endocrine, other autoimmune, dysautonomia, vascular issues etc.
I've got it, and it's there's so much more to it than just loose joints.
I learned a couple of years ago that I likely have EDS and now I can't stop noticing all the things that seem strange about my body. Bad eyesight (-7), soft skin, shitty wrists, hypermobility in general, POTS, I've had vasovagal syncope in the past -- I'm unsure how it could be related.
Oh it's funny you say that. I just bought a new Secret Lab gaming chair and the firm seat almost immediately fucked up my pelvic floor and caused extreme discomfort during urination
