Elaine,
Let me tell you more abt myself. My 1st doctor that treat me put me on high ATD medication, my FT4 back then was low normal range and TSH is detectable. When i migrated to another country, my current doctor said my Ft4 is too low, almost going hypo. He decrease my medicine and Ft4 come up to mid range but TSH is undetectable.
I find that i feel better when my Ft4 is low normal range. I can sleep very well at night, no fast heart rate, only occasional constipation. Now with my Ft4 at mid range, i cannot sleep that well/sleep lesser. I am so full of energy and have frequent flatulence after meal. I can feel my bowel movement is faster, and i have increase appetite. Maybe this is what normal people feel like?
I'm not sure what is call normal symptom because my Ft4 has been low for a long time. My body is used to being a bit hypo. So when my Ft4 hit mid range, i am so full of energy and wonder whether this is hyper symptom? So confused now.
