I have just read Hugh A. Hamilton's book "Impaired Sensitivity to Thyroid Hormone (Thyroid Hormone Resistance)" which focuses on the subject of ISTH - Impaired Sensitivity to Thyroid Hormon and found it to be really good read. Most of it is explained in laymans terms and there are references at the end of each chapter to follow up on.
Hugh happens to be our very own Sandy12 who doesn't appear here much but I believe he is still a member.
