I did find the following article that may provide some of the information you asked.

Can I ask if you have found anything that helps with your symptoms?

@msinvula Hello, I have Hashimotos' and I am treated by a functional medicine doctor and take natural desiccated pig thyroid. Some patients cannot convert the components in thyroid medicine. If I remember right, that is converting T4 to T3 (or that's backwards), but what I can tell you is the synthetic hormones do NOT have all the components and some patients don't feel well on them no matter what the dose is. It would be worth asking your doctor about trying natural hormones. There is a lot of information in my earlier posts in this discussion about how my antibody levels were off the charts while I had old silver amalgam dental fillings, and after those were removed, the levels were very low. You might want to look for something similar that might be toxic to your body that could contribute to thyroid dysfunction. If your doctor doesn't see the value in this, you may want to look for a functional medicine doc. See this link for a provider search. https://www.aaemonline.org/find.php I don't know if steroids are an issue, but my doctor advises against them on a long term bases because of adverse side effects. TSH is thyroid stimulating hormone, and if the body senses the thyroid is producing hormones (or from your meds), that level would drop. Only a specialist could answer what is appropriate because it's tricky and there are numerous components that have to be correct for it all to work in harmony. You thyroid can improve if your health improves and you lower inflammation in your body and get rid of toxicities. I have had my dose cut in half and felt fine for a long time on it. Lately, I have needed more hormones and I have a potential issue with an old root canal in a tooth that may be causing problems and affecting my thyroid again. According to my wholeistic dentist, root canals have cadmium in them to try to kill the infection which is a heavy metal. Silver metal fillings have tin, silver and mercury and with an old filling, the mercury gas leaches out causing toxicity affecting the thyroid that is in close proximity to the throat.

Msinvula, You can read my previous post regarding my journey with Hashimoto's. I will tell you IV therapy has been a great therapy for me. I have been doing an immune IV followed up with a glutithione IV. This has made my antibodies lower significantly. Find a functional/integrated medicine doctor or nurse practitioner that will test all your thyroid numbers, vitamins and minerals, your hormones, it is all connected. Get your vitamin D number up and read about Amino acids because they make a difference. Glutithione turns into a tripeptide that turns into Amino acids that do wonders for you and that is only one there are several that help. I also have been taking a lipo injection, not for weight loss but for the l-caritine, great for boosting energy. I hope this helps, it's a journey, read and try things for yourself, you have to advocate for yourself. Best wishes.
