I voted no. As others have said, I think it depends on what kind of illness. If it's cancer and you're going through chemo and radiation, things about your appearance will change and people will wonder why and the rumors will fly. If it's something like crohn's where you don't really "see" anything wrong then not necessarily. I have a stomach issue called gastroparesis which has caused me to lose a lot of weight. People keep telling me how great I look. Depending on who it is and where we are sometimes I tell the person what the scoop is and sometimes I don't. For most people, them knowing my condition or not isn't going to matter to them. Most of my close friends, family and co-workers know so that if we get together and there's food they know what I can eat. Sometimes you need people to know because you need a support system.
