Book excerpt: Dr. Edwin Lee's process of reversing tiredness will not only give you more energy and help you feel good, but it will also reduce the effects of aging. "In my practice, the most common complaint I hear is, 'I am so tired, but my primary care doctor says all my blood tests are normal.' My book lets you know what those medical reasons are for always feeling tired, and then explains how to increase your energy level," says Dr. Lee. Also in his book, Dr. Lee addresses the controversies of endocrinology (the medical field of hormones) and the areas of endocrinology that are yet to go mainstream. As a respected proponent and authority on hormonal balance and wellness, and as a leader in defining the future of regenerative and functional medicine, Dr. Lee has spoken at major medical conferences around the world. Being board certified in Internal Medicine, Endocrinology, Diabetes, Metabolism (with special courses in Regenerative and Functional Medicine), Dr. Lee knows all sides of the arguments about: adrenal fatigue, the use of T3 treatment in thyroid patients, the use of DHEA, the use of testosterone, the use of progesterone (aside from pregnancy), and the use of growth hormone - to name a few. Being one of the country's most progressive endocrinologists, Dr. Lee treats patients traveling to his office (The Institute for Hormonal Balance, DrEdwinLee.com) from around the world, while also serving as the assistant professor of Internal Medicine at the University of Central Florida College of Medicine. In August 2012, Dr. Lee wrote Your Best Investment: Secrets to a Healthy Body and Mind. It is also available from Amazon.
