I have a strong family history of thyroid disease ranging from my mother, to grandmother, to even aunts. Over the past 2-3 years, I've experienced many symptoms of hyperthyroidism, such as weight lose, fatigue, palpatations, anxiety, etc. I have the blood test done and it comes back normal. 2 years ago, I had a nodule come up and had a thyroid uptake scan done. The test showed hyperthyroidism. I'm already a skinny person, but in a month, I went from 142 pounds to 125 pounds and I'm 5'9. My hair started getting thin and I was tired all the time. LIke I said though, the TSH test has always came back normal. My mom had a similar issue. SHe had all the symptoms of hypothyroidism but her TSH test came back normal. After finally finding a specialist, he did the TRH test on her and it finally showed hypothyroidism. He gave her medicine and she's been fine since. Is there any way that this could be an issue for me as well??
