Every year thousands of women are told they have low bone density. Hormone replacement therapy or other drugs are frequently recommended to prevent onset of the debilitating disease, osteoporosis. Women are also bombarded with information about calcium and dairy products and their ability to prevent bone loss. How accurate is the diagnosis of low bone density and what is the probability of low bone density progressing to fracture in later life? In this book, based on published medical research, Gill Sanson questions the diagnosis, the treatment and the prevalence of a disease that was almost unheard of prior to the 1970s.
