Everyone has their own personal definitions. I tend to consider healthy as in physically capable of major exertion now and not likely to succumb to illness in the foreseeable future. By your definition I was born unhealthy, being lactose intolerant requiring a special non dairy supplement, developed near sightedness, anxiety, hyperthyroid that fixed itself only to become type 2 diabetic. If I'm somehow less healthy than some sedentary but not medication requiring lump that would die running a mile, I think you are a bit off.
Gurps would only count my diabetes as a quirk dietary and medication restriction.
