I had a Ferritin blood test done yesterday for $45 via https://www.mymedlab.com/. My purpose was to ensure that, as my desiccated thyroid dose is raised to 3+ grains, I’m treating the right symptoms. Low Ferritin can mess up thyroid treatment. I was a likely candidate for low Ferritin because of my untreated Celiac disease.
Surprisingly, my result is “336″. The normal range is listed as 22-322. That puts me on the high end of normal. I read more about high Ferritin levels, and my level is no problem.
My above-average level is probably caused by my diet, which is almost all red meats (high in iron), and my heavy use of cast iron for cooking my meat. I may try a different kind of pan, much as I love my cast iron.
I also found sources saying that high Ferritin can go along with hypothyroidism, so that might be another reason it’s high. I’m not going to worry about it, but I’ll test it at least yearly.
Hypothyroid or ‘euthyroid sick syndrome’?
The most informative summary I’ve ever read on the subject of hypothyroidism:

I’ve essentially self-diagnosed myself as hypothyroid, but the above has me interested in whether my root problem is in another system (pituitary, liver, or hypothalamic). I also learned a lot from the post. The sections that stood out as significant to my situation and diet are below, followed by my thoughts. This isn’t really organized, I just wanted to note and respond to the highlights.
My take: A response to local inflammation down-regulates TSH production, which down-regulates thyroid activity. This is relevant to me because my allergies caused local inflammations.
A bacterial infection, he says. How about an allergen that similarly causes an immune response? (He only mentions viruses and chronic bacterial infections.)
On celiac disease:
On iodine :
Edit: Note, author says on the above: “It’s probably important to note that with regards to iodine, it’s people with Hashimoto’s (autoimmune) thyroiditis who may get relief by removing iodine from the diet, but they presumably still need to be treated with T4.”
He also says that hypothyroid people should probably avoid goitrogens, which affirms my suspicion.
Soy milk as a child? Hmm.
On T4 and deiodinases (new concept to me!):
On fasting:
On fructose:
A few other things he suggests, I paraphrase:
