I have recently had a sickness review at work. This only took into account short term illnesses and not my hashimotos, however it was mentioned during the meeting. My managers comments were very blinkered and a lot of assumptions seem to have been made about this condition. when i tried to explain some of these issues i.e. that i was again on iron replacement due to low ferritin levels and i had been told before that this was due to the effects of thyroid disease on menstrual cycle etc. i was just not listened to and told it was not relevant. I have already been to occupational health and provided copies of letters from endocrinologist, however they seemed to be understanding. How can i ensure that my manager is clear about the effects that hashimotos can have, and not just making her own assumptions. NB over the last 2 years i have fluctuated between underactive and over- replaced and have had meds increased /decreased many times. as a result i have experienced symptoms or both under/overactive thyroid.
