So most people will need to take a thyroid-replacement medication, like levothyroxine, for life. This isn’t a cure for hypothyroidism, but medication is very effective at managing symptoms. But if your low thyroid hormone levels are from a medication or excessive exposure to iodine , you may be able to reverse it.

The pituitary gland runs on T3 and if it too is struggling due to D3 enzymes you can end up with hypothyroidism symptoms and other end hormones that are low.
