I think you&#x27;re right, psychosomatic is a better way to think about it. They are intrinsically linked. I also think microbiota plays a big part, which would be physical. Although apparently some research suggests the brain does have an effect on microbiota. I think from a treatment point of view the physical is often discounted far too much.<p>I went through 6 years of lifestyle changes and before trying the thyroid meds.
