I have a clarification/nitpicky question regarding illnesses! The character in question was born with a sort of congenital disorder caused by a drug used by his mother. The disorder renders him deaf, which wouldn't be changed, but additionally people with his condition require daily doses of aformentioned drug to regulate their bodies.

So what I'm asking is, would the reliance on the drug be removed as an illness, or be viewed more as akin to part of his disability?
