The human body is an amazing structure. When all the elements work together, life is good. But it's a delicate balance, especially when hormones are involved. Too little hormones produce disease such as when insulin decreases, diabetes results. Or, too much hormone, as with parathyroid hormone, causes high calcium and promotes osteoporosis. Sitting on top of the kidneys as shown on the cover, adrenal glands make various steroid hormones such as aldosterone and cortisol. Very important with multiple fundtions. In You are What You Secrete, author Dr. Ellis Levin offers a look at common, hormone-related diseases such as diabetes, thyroid, and bone disease. He provides an understanding of how the disease progresses, what symptoms can be expected, gives steps to prevention, and tells how to prevent the disease. In addition, he discusses the current and newest treatments and expected future developments. Levin teaches how the key to a healthy body is to maintain normal amounts and activities of the many hormones secreted by almost every organ in the body. Measuring hormones by your health care practitioner will define potential problems early, to prevent many symptoms that often occur.
