Thyroid meds? Drugs? Here we clean out the inside of the body and support the thyroid using natural iodine from plants or trees and get off the drugs. We use nutrients to re-build and normalize. It may take a while.
Chiropractic can do wonders to help. I've noticed that if the body isn't clean inside, the treatments don't work or hold very well. If he's 61, it will be worth doing what will get him well so he can get rid of the drugs. He's the one who will have to be interested in doing it.
