So, a normal mortal can only kill the physical body of a dragon, their soul lives and they can be resurrected.

Dragonborns and other Dragons are the only things that can permanently kill dragons by absorbing their soul.

Can they die (in any way) by starvation, dehydration, illness, etc?

(I'm going to assume they do eat, because sometimes armor and such can be looted from dragons. I guess Alduin can eat souls too.)
