Hello all! I am about 9.5 weeks along, and I had some bloodwork done to see how my thyroid was doing last week. My TSH was .09, which is low. I was wondering if anyone had any experience with this? I am very worried that it will cause miscarriage or an abnormality in the baby, and I have spoken with my midwife who suggests seeing a specialist and asking for Armour thyroid medication, which is a natural medication made from porcine thyroid. Any advice would be much appreciated! Thank you!
Do you have a history of hypothyroidism? Your test results show that you are a little hyper, maybe over-medicated a bit (maybe not, I read it is better to be a little hyper in pregnancy and also depends on how you feel). You really need to have Free T4 and T3 levels checked to tell if you are where you need to be. I've read that T4 and especially T3 need to be in the upper 1/3 of the range for pregnancy. These ladies have been helpful to me: http://community.babycenter.com/groups/a3695/thyroid_issues_concerns. They also recommended I get on a natural thyroid supplement. I am going to see an endocrinologist on Friday and am going to ask him about getting on Armour or NatureThroid or at the least adding a T3 supplement like Cytomel. I am hypothyroid and miscarried in March. I'm on Synthroid 75 mcg/day now.
Normal TSH Levels DURING PREGNANCY
According to research, during a normal pregnancy, the following are the TSH normal ranges for an iodine-sufficient population without autoimmune antibodies...
First Trimester: 0.24 - 2.99
Second Trimester: .46-2.95
Third Trimester: .43 - 2.78
Thanks so much, Serenyd! My mother and grandmother both had their thyroids removed, but later in life--not during childbearing years, so I was really surprised to have this creep up on me. I have been feeling tired, but I thought that was normal during the first trimester of pregnancy. I have never been on medication for my thyroid before, so I am really nervous about doing so. I have heard it is really difficult to convince the two endocrinologists in our town to prescribe Armour, so I am keeping my fingers crossed. I am so sorry about your miscarriage in March. Thinking about you! I also miscarried in January, and I am wondering if it had anything to do with thyroid levels. I am keeping my fingers crossed for you during your Friday appointment--hope they let you go the natural route:) Keep me posted! Thanks so much for all the resources and your kind words.
Why did they have their thyroids removed? That is usually only done in hyperthyroidism. That where your thyroid produces TOO MUCH thyroid hormone. Thyroid hormone and TSH have an inverse relationship, TSH goes down when thyroid hormone is high. TSH stands for thyroid stimulating hormone - it is produced by the pituitary gland and is messenger hormone that tells the thyroid what to do (make more thyroid hormones or make less). You don't need to be on Armour (desiccated thyroid hormone) if your thyroid is over-producing hormones already. It is doubtful that they will want to treat you in pregnancy, mostly likely they will just monitor you. If you end up getting your thyroid removed later on, you will need Armour or a similar medication, because your gland won't be there anymore to produce the hormone you need. I hope that makes sense.
I'm really curious why she suggested Armour for a low TSH. Low TSH means you're hyper, not hypo, and Armour doesn't treat hyperthyroidism. Even that level of .09 isn't THAT hyper either. You should be monitored to make sure it doesn't get worse. If they decide you need meds you'll need radioactive iodine or anti-thyroid meds, not a TSH suppression med like Armour and Synthroid are.
Make sure you find a doctor that actually knows what they're doing in regards to thyroid. It's sad but many many providers think a lower number means low function. That's not true. So look around and try not to worry.
Thesilence- I wasn't able to see one of our town's two thyroid specialists until August and I thought I just couldn't wait that long, in case there was a major problem. A friend of mine suggested a GP that specializes in natural thyroid treatment and I had t3, t4 and antibodies tested and they all came back normal! I am so relieved, and I will be tested again at 28 weeks. Thanks for your support!
I'm really glad everything came back normal. Continue to be vigilant in getting your levels and antibodies checked every year. I am positive for antibodies but I have Hashi's not Graves. From what I have heard it is 2 sides of the same coin, both autoimmune mediated. My mistake was not getting checked every year. I should have. Maybe my miscarriage could have been prevented. Good luck!
