My husband has eds hypermobility can he get disabled?

Not necessarily. Good teaching in joint protection will prevent disability. Fibromyalgia frequently accompanies people with hypermobility without apparent arthritis. I encourage your husband to take care of himself so that he does not become disabled. Living off of disability is a meager existence.
Probably not. For disability, you have to prove that you can't do any job that you might reasonably get hired for. I have physician colleagues who have fairly significant Ehlers-Danlos and have things they can't do because of it, but they're able to work. Frankly, if he's a decent man who loves you, he'll want to earn a living and not have the stigma of disability when he appears able-bodied.
