Question: Do said Thyroid lab is normal but...

 Yappy00 - Sat Sep 22, 2007 9:10 pm

I am 35 years old and just had my 2nd child 3 months ago. Now I am rapidly gaining weight and my hair is falling out like crazy. I lost 45 pounds being pregnant and I can only lose a significant amount of weight when I am pregnant. My TSH was 5.178uIU/ml, T4 was 9.5ug/dl, T3 26%, and Free Thyroxine Index was 2.5. My cholesterol was high so my doctor said I just needed to go on a diet and prescribed Adipex, but I have been watching what I eat so I would not gain the weight back. Are my results within normal range?

User avatar Hi Yappy00,

Unfortunately I cannot answer this for sure because normal lab values vary from lab to lab. With my lab reference ranges, a TSH of >4 is considered high and consistent with hypothyroidism.

If your labs are normal I would also recommend testing a free T3 level. In rare cases the T4 may be normal but the biologically active T3 is not.

You may benefit from seeing an endocrinologist to help sort this out.

Best wishes.
