so weird you should mention anemia to the above poster. I saw Dr. Brownstein today and he thinks low iron explains my extreme fatigue, weight gain, and apparently I look pretty pale. If the iron supps don't help, have to do more bloodwork. Have only been taking around 25mg of Lugol's, but it has helped some - thyroid still nodular, but less swollen.
I would check the iron levels again. I had borderline levels 4 months ago, and we didn't do a blood draw today, but the major fatigue happened in the meantime, and based on looking at my lower eyelids, symptoms, and paleface thing, we think it's probably iron deficiency. I used to get that blacking out a little bit thing - fairly frequently, and I wouldn't be surprised if that was the problem.
He did say good iron levels support the thyroid, so that's good news.
