A bit of history before I get to my question: I was diagnosed about 4 years ago with thyroid cancer and hyperparathyroidism. Two surgeries and some radiation later and I’m without my thyroid gland, and down 2 (of 4) parathyroid glands as well. Since then I’ve been taking levothyroxine, always hovering around a dosage of .137mg and a TSH ~0.1.
So, that brings me to the present. I stopped taking hormonal birth control (HBC) about 5 months ago and my TSH hasn’t recovered. It shot up to 10.5 so I increased my levo dosage twice and my TSH only moved down to 4.5. I’m sure I’ll be increasing the dosage again, but does this sound backwards to anyone? I thought that going off the HBC would lessen my medication requirements, not increase them? All my other levels are fine, good even; it’s just the darn TSH. Anyone else had this problem with going off HBC? Could there be any other cause for the stubborn increase in TSH?
