I've been reading about hyperthyroidism because my mother was suffering from undiagnosed autoimmune hyperthyroidism (possibly graves disease) when she became pregnant with me.
I was 5 years old when she was eventually diagnosed because her weight went down to 4 and a half stones, her eyes were protruding, and she developed a goitre. From what I have been reading recently, it seems that the thyroid antibodies cross the placenta to the foetus. Up until now I had just assumed that I inherited the autoimmune thyroid disease from her (although mine is underactive), but never really understood much about it. She told me that after her thyroidectomy she decided not to have any more children because she was on the thyroxine and my father was on blood pressure medication so she didn't want to take the risk of harming any subsequent child.
What I am wondering, is whether, after thyroidectomy, does the body stop producing the antibodies because there is no thyroid to attack?
This is a major concern to me currently because my daughter has autoimmune hyperthyroidism and has just had a baby. She was being treated with carbimazole prior to the pregnancy and her thyroid problem calmed down but has now started up again since the baby was born, and she is having more treatment.
