Miscarriage r/t Hashimoto's

[Lalm]

I am a healthy 24 year old female and I was 8 weeks pregnant with my first pregnancy.  I had a miscarriage recently and I am wondering if it related to Hashimoto's disease.  I was diagnosed a few years ago; however, I did not start hormone replacement until my free T4 became abnormal with an elevated TSH.  I was currently taking a dose of Eltroxin 50mcg. After starting meds my TSH was 2.88, then in April it went to 5.05, and a few days ago it was measured at 9.63.  As a result my MD increased my dose to 75mcg.  Would this be an considerable factor to why I miscarried?  In addition, when I TTC again what factors should I consider regarding my thyroid?

Sorry about your miscarriage.  

I don't know too much about this issue, however from what I have read, you want to have levels check frequently for they will change throughout pregnancy.  It is suggested TSH be between 1 and 2 at all times, even before you get PG.  If you are Hashi, I understand antibodies can cause miscarriages. So you want your thyroid health kept at top condition as possible.

Good luck next try and Gods Blessings.

Yes, it would.  I am sorry for your loss.  I have hashimoto's (and thyca twice) and I have miscarried several times, once around 8 weeks.  

Just make sure your doctor checks your levels every 2-4 weeks during your pregnancy and changes your dose accordingly...also he needs to check it the day you get your BFP to catch it early.

Thanks for the replies.  I'm definitely going to make sure I address this issue with my Dr before TTC again.  I always knew that thyroid problems could cause difficulties, but I thought that I would be okay because I was on meds; however, when I got my TSH back this week it made me worry because my TSH was elevated again.

Hi.I too have hashimotos. I was diagnosed to late though after having 2 miscarriages. I got pregnant with my daughter Fall os 2005 and had to take progesterone to maintain her. She was born with a heart condition which may have been because of my untreated Hypothyroidism. I didn't find out until I was 36 weeks pregnant that I was Hypo. After her birth, it really got out of hand. My TSH was >150 and my antibodies were 3500. They should be less than 30. My doc has told me that I can have a normal pregnancy after this. I just don't know. I guess I will try and see. I don't plan to try until next year though cause my thryoid is still not under control and I am at TSH 5.99. Undiagnosed and untreated can cause miscarriages and I think the fact that it is autoimmune plays a factor. There is a book on miscarriage and why it happens that talks all about the reasons. It has an area about the thyroid in it. I read the whole thing when I was preg. Hmmm. Wish I would have thought of it sooner!

Hope this helps. Good luck to you...

Thanks for the reply.  I actually bought a couple of books yesterday, one on miscarriages and the other on thyroid problems and management.  It's frustrating because all of my Dr's that I've had haven't ever really been concerned with my hashimoto's or underactive thyroid.  I haven't even been tested for my antibodies level since I was diagnosed 3 years ago.   I'm having a follow-up appointment with my OB soon and I'm making sure that I am vigilant this time round and that I ensure everything with my thyroid is within therapeutic range.  I obviously can't say for sure if this is why I miscarried and I might have no problems next time, but I definitely want to take away any risk factors.
