my daughter 32 yrs informed me she has hitachi disease,sorry I know that s not exactly correct, but she makes me nervous so i only heard part. She said she is fine. She had been treated for low thyoid, even though still thin but, blood count was still very high or low,sorry. So she was sent to an endocronoligist and they found this disease.Any information could help and sorry for the misspelling . thank you for your time. annie
