The human body just cannot get sick by itself without the impacts coming from external agents. In that sense, all illnesses are linked to some pathogens, and inflammation is simply a reaction of our immune system fighting them off. In my opinion, a lot of illnesses are really just a form of autoimmune disease. Our body must have been fighting some unknown pathogens for a really long time and without our awareness, eventually it just succumbed and triggered those conditions.
