Thyroid tests are about the 'norm', but very few people actually fit into that hole - "normal" does not always mean normal
for you.
A lot of the reading I have done recently questions the current 'norms', and the revised levels would at least show your TSH is too high (not sure about the others).
An easy self-check that tends to be more accurate than blood tests is to take your basal body temp for 3 days in a row. As soon as you wake up (same time each day), stick a thermometer under your armpit & leave it there for about 10 mins (hit snooze on the alarm). They say menstruating women get the most 'real' results on days 2 & 3 of their cycle (hormones will affect BBT). Average out the results. Anything less than 36.5C indicates hypothyroidism.
There are many foods that also affect thyroid function & hormonal changes after pregnancy often trigger probs. I have started the
How to Lose Weight - Hormones and Better Health - MassAttack - Australia program to sort out my thyroid/hormone issues - herbs, supplements & dietary/lifestyle changes. Certainly worth a look.
If you are prescribed thyroid medications, try to get natural thyroid extract instead of synthetic versions. A lot of people react to the synthetic version or don't get good results. The natural supplement (provided you're not vego) is much more effective & has the full range of thyroid factors needed for normal function.
