As someone who used to spend a lot of time interviewing job applicants, I think that Worthington45 gives you some excellent advice. Usually a hiring manager has several applicants to chose from. If an applicant told me that he had a "serious" illness that is "essentially" resolved (this implies that it is not resolved), I would consciously and unconsciously put that applicant at the back of the line since I might construe that the applicant is telling me to expect occasional absenteeism due to health issues. I also would not advise that you tell any coworker about your illnesses or personal information as they will inevitably spread that information to others, usually in a distorted or sensationalized form. When hiring, the most important traits I looked for were enthusiasm, intelligence, a good work ethic, a sense of humor, and ability to get along with others. Your medical history is your business, no one else. I am sure that most applicants are not hired for what they said rather than what they did not say during the interview.
