Then I would search thyroid in the search bar at Curezone and see if anything pops up that relates to reactivating the thyroid. A diet change and herbs may help. Dr. Dennis Hardy knows a lot about herbs, you might benefit from asking him if there's any that support the thyroid.
What is your diet like right now? Can you post what you eat in a typical day?
If you clean up your diet (when you post it we'll be able to see what needs to change), you might want to consider doing some serious cleansing (ie. liver, gallbladder, kidneys) afterwards. Starting to exercise, even if it's just walking 5 minutes a day, is crucial to your heart.`
You have the info, now run with it and make a positive change in your life :)
