It is all interconnected, but I am unsure about the claim made. The reason is simple: there can be numerous disease types. Person A may have different genetics than Person B, as one example, so responses of a body may be different for that reason alone; then there is lifestyle choice, health, age and so forth. So I don't agree with the claim in the title here that all is one ailment - that makes no sense to me.
