If you're still suffering hypothyroidism symptoms despite treatment, your first step is to document this in a way that you can review easily with your doctor. A good tool to help is the Hypothyroidism Symptoms Checklist, which offers a checklist of risk factors and symptoms you can take to your doctor to help get a diagnosis, or make the argument that your hypothyroid symptoms are not resolved by your current treatment.
Before you have your discussion with the doctor, I'd also suggest you read two key articles: Six Questions You Ought to Ask Your Doctor...And How to Interpret the Answers, covers the six critical questions you really should ask your doctor about your hypothyroidism. Diagnosis: Hypothyroidism --Answers to Some Common Questions, answers the main questions a newly diagnosed person with hypothyroidism often asks, such as how long it takes to feel better after starting treatment, long-term health risks, whether or not you'll get a goiter, fatigue and weight gain and how to combat them, and more.
Armed with information and your checklist, you should sit down and have a discussion with your doctor about your optimal TSH level, and whether or not you should be considering the addition of T3 to your thyroid hormone replacement therapy.
You may also need some ammunition in getting your doctor to listen and understand. To help, there's are various books that I recommend for all thyroid patients. See The Thyroid Bookstore for ideas.
If your doctor won't discuss options, or refuses to consider the T3 therapy without providing clear, valid, and substantiated reasons particular to your own medical situation, then you'll need to find a doctor who wants to be your partner in wellness. If you want to find the doctor to help, you can search for a good doctor recommended by our fellow thyroid patients at my Too Docs Directory. The Directory features US and international doctors by state or country. If we don't have a doctor for your area, you can enter your request there as well.
