@diverdown1 There are studies out there that say the same, especially with regard to stress. I have also read on rheumatology websites that ANA titers in particular can actually fluctuate over time.

I put the website to Dr. Kevin Tracey on another discussion thread, and I’ll pop it here, too. The FDA recently approved his vagus nerve therapy for certain inflammatory conditions.
