Hi Jo6366,
My DD1(12) has hyperthyroidism. Her Daddy had it and his brother and their mother, DDs granny. So there is a massive family link in our case.
My late husband was undiagnosed until at the age of 15 or so he was massively underwieght and having regular palpitations, to the extent that he thought he must be having a heart attack.
When DD was born she was a ravenously hungry baby, breast feeding every 20 minutes, day and
night!!! Never slept through until she was 5 after starting medication. (prior to that she'd sleep fitfully from about 11pm til 5.30amish)
She was tiny (still is) and on the 9th centile for weight.
No health professional ever made the conection
between her behavior and growth and her dads thryroid problems.
On starting school we were constantly called in for her lack of concentration and bad behavior. She was a very unhappy little girl.
Her Daddy died when she was 1 of another autoimmune disorder (hyperthyroidism is caused by the immune system attacking the thyroid gland)
and I became obsessed with making sure she wasn't developing the same thing. So frequently went to the docs with my concerns.
On one of our frequent trips to see the geneticist and paediatrician it was decided to test her. Lo and behold her TFTs were off the scale.
She takes carbimazole daily to supress her thyroid glands hormone production. We go for 6-12 weekly blood tests, depending on how she's doing.
On the whole she's ok, although she's in the midst of a manic period. Her consultant said as she has growth spurts and her puberty kicks in her thyroid will also play up. So lots of irritabillity and sleeplesness.
She eats like a horse and is still thin as a pin. Does your LO eat alot?
