This is a Medical Self-Help Book on Hashimoto's, Graves, ' Iodine, Levothyroxine, and Natural Desiccated Thyroid. The book compares natural desiccated thyroid to levothyroxine for treatment for hypothyroidism. There is extensive discussion of the diagnosis and treatment of Hashimoto's thyroiditis, Graves' disease, autonomous nodules, multinodular goiter, and other thyroid disorders using conventional and alternative methods. Medical Imaging, Blood Testing, Iodine supplementation and Adrenal Fatigue are also covered. he Silent Epidemic and Unsuspected illness Depending on which source you read, between 10-30 percent of the population has some kind of thyroid disorder, and many of these suffer needlessly. This state of affairs has been expressed as a silent epidemic or an unsuspected illness. In 1891, thyroid extract was first used to treat thyroid patients, representing one of the first medications in the history of western medicine. Since these early days, the basic science of thyroid has made a quantum leap. Although publicly available in the medical literature, current breakthroughs in thyroid science are largely ignored by mainstream medicine. The practice of thyroid endocrinology remains outdated, hampered by dogmatic reliance on older tests and treatments. The goal of this this book, Natural Thyroid Toolkit, is to bring state of the art thyroid diagnosis and treatment into the public realm. The reader is provided with a unique blend of information from both clinical experience and from the thyroid medical literature. This book includes copious references to in vitro and in vivo basic science studies as well as the more formal clinical trials in human populations. This book represents 20 years of prescribing natural desiccated thyroid in the outpatient clinical setting. Errors in Modern Thyroid Endocrinology This book discusses many of the errors in modern thyroid endocrinology. One of the errors of modern endocrinology is the dogmatic reliance on the TSH laboratory test, a classic example of the misapplication of a laboratory test. The second error is sole reliance on levothyroxine (T4-monotherapy) in the treatment of hypothyroidism. Combination therapy with natural desiccated thyroid containing both T3 and T4 is a superior and more robust treatment. There are more errors: Treating thyroid hormone levels while ignoring the autoimmune component of thyroid disease. Failing to treat euthyroid Hashimoto's patients promptly with thyroid medication. Failing to treat pregnant women with thyroid medication when anti-thyroid antibodies are elevated. Failing to test for and treat with iodine because of "Medical Iodophobia," the irrational fear of using iodine. Another error is ignoring the beneficial effects of selenium, magnesium, vitamin D3, and a gluten-free diet for autoimmune thyroid disease. My sincere thanks and gratitude goes to Dr. David Brownstein for writing the foreword for this book.
