Hi Birdy - thanks for the advise. They are doing a thyroid panel test, B12, folate and ferritin.
My dad has overactive thyroid and I was wondering if that may be the issue with me as I am having to get up in the night to eat, sometimes twice, am always hungry and I have episodes of a very fast heartbeat. But my TSH was 1.2 back in March and the T4 was 16 so all normal apparently!
The weird thing is my nails are growing really fast now but it's just the hair shedding. Today was hair wash day and so much came out. It's freaking me out! I feel like jacking in the HRT but then that would be a stressor to the body too so I'll just stick to the same dose in the meantime. Thanks for your help.
