i have hypo thryroid. i was taking 137 of synthroid, and 5 of cytomel. my new endocrinoigist dropped my synthroid to 125 a year ago and kept the cytomel at 5. my hair starting falling out at an alarming rates and still is, its been doing this for over 8 months. i have half as much hair. i have been to dermatologists about this, and have since changed my endocrinologist. just last week i have started on armour thyroid 90 and am taking antihistamines, i am trying to figure out if these unusual skin issues are thyroid related. and if my hair issue as well. my endocrinologist suggests perimenopause but all my hormone tests do not support that. my endocrinologist is fixated on TSH determining dosage. my dermatologist says i have too much histamine in my system and i should take benadryl. they do not agree with each other about what is going on with me and i am looking for an insight, an answer. any one have similar experience and success remedying it? anyone have an idea? i am venturing into a low histamine diet, ditching aged cheeses, cured meats, chocolate, alcohol, coffee, dried fruits. whats left? actually a lot! is this an undertreated hypo thyroid problem?
