I went to the doctors recently after experiencing increasing fatigue, to the point where I was in bed by 8:30 each night and often needed an afternoon nap. Thinking about it, I had been feeling generally tired for a long time, if not years before this decline. I am a 22 y/o female, 5"2, and follow a vegetarian (~90% vegan) diet.
I also feel the cold constantly, especially my extremities which can discolour and wear bed socks. I am average weight, but have weight that sticks around my lower half despite being very active (half-marathons and training for triathlon, cycle every day). This made me look into hypothyroidism as it all fits me so perfectly. I have fine brittle hair and nails, frequently feel faint when I exercise, low blood pressure, a sore throat and sometimes headache each morning, and always had light periods with a long cycle.
We did some blood tests, which showed:
Ferritin= 12ug (range 15-200ug)
TSH= 1.6 (range .4-4.5)
Free T4= 13 (range 10-24)
My doctor called this Ferritin level "very low" so am being prescribed iron tablets twice a day for 2-3 months but I can't help feeling that my other hypothyroid-like symptoms are left unexplained. I have also read (not necessarily understood...) about a link between ferritin and thyroid function and want to request a Free T3 test, if just to give me peace of mind.
Has anybody had a similar profile? What steps did you take? Will Iron help the hypothyroid symptoms?
