Then I had a month without getting medication and then I had new tests and the results were : TSH : 3.9 Μiu/ml T3 :.1.54 ng/ml T4 : 2.1μg /ml Anti-T : 2 IU/ml ANTI-PO : 18 IU/ml B12 : 349 pg/ml I am 30 years old, 1.67 m tall and I weigh 54 k. I never had obesity problems, the opposite I could say. I had the thyroid test because of the fatigue I felt and my mood changes. I don’t smoke or drink, and I exercise regularly.
