I was very disappointed with this book. To start, there is not much too it. The main chapters of the book comprise a total of 42 pages. Pages 43-102 are a personal health diary which the reader is supposed to fill in. The remaining pages, all 18 of them, are a conclusion, resources and a chapter about the author.There is very little information in the book that can't be found on most web sights about hypothyroidism. The diagrams, especially of the author's test results, are mostly unreadable. They looked like copies of a fax.I cannot and will not recommend this book to anyone. If you want a good book about Hashimoto's Thyroiditis, get Mary Shomon's book.
