It probably wouldn't be cured completely, but depending on how big the condition is in terms of their personality - as some people do let their medical conditions dictate their personalities - then their semblance may be something that circumvents it. Like a lactose intolerant person whose semblance turns all lactose they have into super speed or strength, or something.

If they eat something with lactose in it and don't activate their semblance, they'd suffer the normal effects. But if they do, they'd get the boost.
