Mirena and thyroid disorders

Check this out.  I found yet another web site with 1100 posts of Mirena side effects, http://www.medications.com/se/mirena

I, too, had my thyroid levels checked twice when I had the Mirena b/c of my symptoms.  Both doctors that did the tests said they came back "normal" but to me they were low--0.975 when the reference range is 0.350 - 5.500, and some docs treat levels below 3.0 (see http://thyroid.about.com/od/gettestedanddiagnosed/a/normaltshlevel.htm)

Anyway, read this woman's story.  My best friend also just had a partial thyroidectomy and she has had the Mirena for 4 years!  I didn't think there was a connection until now.

Hi Ladies,
I am 31 with 3 beautiful children. I have had the mirena since July 2007. I now have a thyroid disorder called Hashimoto's thyroids. No personal or family history of any type of thyroid diseases. I am having mine removed in 4 days. Of course my family practice MD claims there is absolutely no connection between the mirena and my new onset of thyroid disorder. Just FYI for all of you ladies out there, the symptoms most commonly reported by a majority of you, take a look at the symptoms of hypothyroidism.
Symptoms of Hypothyroidism

Fatigue
Weakness
Weight gain or increased difficulty losing weight
Coarse, dry hair
Dry, rough pale skin
Hair loss
Cold intolerance (can't tolerate the cold like those around you)
Muscle cramps and frequent muscle aches
Constipation
Depression
Irritability
Memory loss
Abnormal menstrual cycles
Decreased libido

Any of these sound familiar??? All of my labs including my thyroid (TSH) levels came back normal. Except one. PTO, the test for thyroid antibodies. My immune system is literally attacking my thyroid. Thyroid levels under 3.0 are looked at for many women with infertility and miscarriage. Mine was 2.44, which is within normal range, but I am also on the verge of hypothyroidism. 3 weeks ago I noticed a lump on the left side of my thyroid, I just found the infertility information late last night, and that's how I wound up here. Mirena is doing its job, but it is also messing with your metabolism. Just because your thyroid levels are within normal range does not necessarily mean you are not having thyroid issues or it may be early enough where your levels are not "concerning" yet. No connection between thyroid and Mirena, huh???? Good Luck to all of you.
