Any Plugins/Easy Mods for an Extended User Profile

I’ve searched on here - but can’t seem to see anything. Does anyone know of a plugin or easy modifications that someone might have done for an extended user profile capability.

I’m considering doing a new healthcare related forum and would like the ability for users to add … on an ongoing basis over time… information like medicines being used, side effects experienced on those medications, etc.

Any help or pointers on this greatly appreciated!
