Please keep in mind that the "standard" testing and "standard" treatment by synthetic T4 only may not work for all people. If you have been diagnosed with hypothyroidism, and are still not feeling well after adjusting to your medication, you may want to consider other options available for treatment of hypothyroidism. Those include synthetic T3, as well as natural desiccated thyroid medications. Each person will respond differently to differently medications, and finding the one that works for you is the best medication.
Also, if your hypothyroidism is indeed due to an autoimmune response, start researching ways you may reduce the autoimmune attack via lifestyle changes, diet and supplementation. Treat this disease as a whole, not just the symptoms. You may be like me and have a family history of autoimmune thyroid disease, but there are ways to minimize the attacks and continue to keep your energy and health up. It may not always be easy, especially since you may be feeling worn out, sick and tired all the time, but if you can push through that and start to treat your body as a whole, you can feel good again!
