I have had Hashi now since 2000, i got it when I was still in high school. They though that was rare that this would occur at such a young age. No one in my family had it, well not quite yet. I was the first to get diagnosed. My gyn mentioned that there is a link between autoimmune and preeclampsia. I had a terrible preg. I take synthroid now well the generic. And I do not feel much better at all. But people who use Armour should be careful. My endocrinologist strongly disapproved to this. It is Pig tyroid. This is from a site "The prevailing opinion is that everyone converts all the T4 needed into T3 automatically, and that drugs such as Armour and Thyrolar are outdated and old-fashioned at best." Also does not mention much on Hasimoto patients like myself. I would like to try it though to feel better. The side effects are higher as well. Esp long term.
Unfortantly, what works for one, does not always work for another person. So though some have problems with there synthroid others do not. Also it takes a while for you to notice a difference with this. IF you take it regularly at the same time and follow instructions on eating as well as not take it with vitC then you should be experiencing something. If not then you really need to get a new endocrinologist. Regular doctors are not made to deal with these issues, though they try, you need to see a specialist. Just remember that you know how you feel and if Synthroid is not working for out then change.
