I was wondering whether any of you have family history of thyroid problems and if this has affected your condition. In my case, all women in my family have had problems at one stage or another - be it thyroid cancer or Hashimoto. I was 19 when first diagnosed with overactive thyroid, abnormal TSH level. So far I haven't met any people with family history and I would be very glad if there are any of you out there who can share their experiences. Thank you!
