I've been suspecting hypothyroidism for a while now, as I seem to have symptoms relating to it, such as difficulty in losing weight, unexplained high cholesterol, absent periods, difficulty concentrating and remembering things, dry hands and flaking nails. I had myself tested last year but the doctor said I was fine as the results were within range. However, I got them tested again and here are the results:
TSH 1.61 range 0.4-4.0
F T4 10.48 range 10-21
TSH 1.34 range 0.4-4.0
F T4 9.64 range 10-21
This is somewhat confusing as my Free T4 is below range, although my TSH is completely normal. I've been researching and this and think that this may be an indication of central hypothyroidism? Should I try to ask for medication or more lab tests?
