Always cold, tired after a full night's sleep, and dealing with brain fog or thinning hair? Symptoms like these often lead women to ask about their thyroid. One of the most common questions Dr. Alyssa Louras, a naturopathic doctor at our Whitby clinic, hears is whether Hashimoto's and hypothyroidism are the same thing.
They're not. Hashimoto's is an autoimmune process, where the immune system makes antibodies that affect the thyroid. Hypothyroidism describes what the thyroid is doing: not making enough thyroid hormone for the body's needs. That means you can have Hashimoto's, with positive thyroid antibodies, while your TSH and free T4 still look normal.
Knowing which one you're dealing with matters for treatment. Levothyroxine replaces thyroid hormone, but it doesn't directly turn off the autoimmune process. (Always talk to your prescriber before changing any medication.)
Several things can play a role in Hashimoto's, including family history, pregnancy and postpartum changes, stress, sleep, and gut and immune health. None of them mean you caused it.
For new moms, postpartum thyroiditis can look a lot like normal new-parent exhaustion. If it's lasting or getting worse, ask your provider about thyroid testing.
"This is why I like to look at the whole picture and get comprehensive bloodwork done." Dr. Alyssa Louras, ND
