It covers hasimotos disease as well as many other topics. He had hypothyroidism type 2 as well. There are a number of doctors who have contributed to this book as well. I had been trying to figure out problem for years with no help from GP’s. A clerk in a health food store recommended this book. Finally all my symptoms were in black and white in front of me.
