My mum was diagnosed with hypothyroidism whilst she was pregant with me, and I've now been diagnosed after struggling with tiredness, depression etc. for years.
It doesn't run in her side of the family but there is a history of it on my dad's side. I can't seem to find any research on the effect of a hypothyroid foetus on the mother, or vice versa (other than untreated).
Is it possible that I gave it to her? I haven't had an antibodies test yet, so I've no idea if it's Hashimoto's (or even the cause of it). Or is it more likely that her development of hypothyroidism caused me to have it? Or could it be entirely unrelated?
