Sam17b You are currently undermedicated to have a TSH over range, below range FT4 and low FT3. You need an increase in dose.

Also, you have autoimmune thyroid disease aka Hashimoto's, as confirmed by your high antibodies. Did anyone tell you this? Hashimoto's which is where antibodies attack the thyroid and gradually destroy it. The antibody attacks cause fluctuations in symptoms and test results.

Maybe you've had dose changes in the past due to results/symptoms. As Hashi's causes swings from hypo to hyper and back again to hypo, some doctors who don't understand what Hashi's is change the dose and leave the patient unwell when hypo symptoms return.

You can help reduce the antibodies by adopting a strict gluten free diet which has helped many members here. Gluten contains gliadin (a protein) which is thought to trigger autoimmune attacks so eliminating gluten can help reduce these attacks. You don't need to be gluten sensitive or have Coeliac disease for a gluten free diet to help.

Supplementing with selenium l-selenomethionine 200mcg daily can also help reduce the antibodies, as can keeping TSH suppressed.

Gluten/thyroid connection:


Often Hypo and Hashi's patients have low nutrient levels. Some of your symptoms suggest that. Have you had the following tested, if so please post results with reference ranges for comment

Vit D
