I was diagnosed with Hypothyroidism in 93 I ve been on Levothyroxine since. I ve always been on a high dose, currently 175 mcg. I had blood work done December 2014 my TSH level was 0.83, I changed PCP this past March, April he ordered labs including TSH, TU, T4, my TSH result was 0.11 ( low) I m confused on why and my PCP couldn t really give me a reason the only thing he ordered me to do was to skip a dose 1x / week. The only thing new I have initiated in my life is a change in my diet, I m now eating a gluten free, soy free, dairy free diet, no processed foods, no sugars only organic stevia or organic raw honey. Are the drastic changes in my thyroid levels due to diet change?
