Hi doctor, I recently did blood test because i was experiencing unexplained weight gain (despite a very healthy diet and exercise regimen). My tsh level was 1.24 (normal is 0.27-4.2), T3 is 1.29 (normal is 1.28-3.31), ft4 is 12.47 (normal is 12.0-22.0) I feel that my T3 and FT4 are all borderline low and since I also experience other symptoms of hypothyroidism, i might have it but the doctor dismissed my suspicions. A few months later when the weight gain persists despite my efforts, i went for another blood test with another doctor (this time she only tested for FT4) and it was 10.5 (normal being 9.0-25). This number would've been out of the range if using the previous range! I am convinced that I might have some form of hypothyroidism but no one believes me ...
