None is more readily and inexpensively corrected. And none is more often untreated, and even unsuspected. Hypothyroidism -- low thyroid function -- is one of the gland disturbances that many people suffer from without even realizing it. It can be the cause of low energy or constant fatigue that is one of the most common complaints brought to doctors. It may be responsible for chronic headaches, repeated infections, unyielding skin problems, or circulatory difficulties. Even more frightening, it can be a major factor in heart disease, lung cancer, and emphysema. And it is responsible for many emotional and mental disturbances. Hypothyroidism: The Unsuspected Illness explains low thyroid function in easy, understandable language. It tells how it may be affecting your health and your life. Dr. Broda Barnes and Lawrence Galton tell what the thyroid gland is, how it works, the problems its dysfunction can induce. They detail case histories of patients, often thought hopeless, whose problems were discovered to be related to hypothyroidism and were cured by Dr. Barnes's simple effective techniques. And they discuss whether you too may be hypothyroid, affected by a condition even a physician may not recognize. Included is a simple test you can make at home to discover if hypothyroidism may be the real, previously unsuspected cause of your ill health. If you know you are hypothyroid, Hypothyroidism: The Unsuspected Illness will answer your questions about your condition. If you suspect you maybe, if you are unsure what may be causing those chronic headaches, infections, fatigue and low energy, it may help you find the answer.","forthcoming":false,"isbn13":"9780690010299","publication_date":"19760101","publisher":"HarperCollins","slug":"hypothyroidism","subtitle":"","title":"Hypothyroidism"},"discovery":{"categories":{"all":[{"bisac_code":"HEA039160","confidence_band":"high","label":"Endocrine
