There is evidence for cyclic inflammation by the innate immune system and also latent inflammation from gut bacteria and their outputs.&lt;p&gt;What you are describing (bone marrow radiation) has been used to treat Multiple Sclerosis.  But diets (which radically change gut bacteria) have also been used to treat MS.  So it&amp;#x27;s complicated, and it&amp;#x27;s possible for what is currently considered a single disease to be a common symptomatology for different root causes.</text></comment>
