About one in six people suffers from chronic headaches. In Australia, it is estimated that about three million adults get migraines; based on that figure, on any one day almost 100,000 will have one, with about half missing work or school. And that one-in-six statistic is narrowing every year. Why are headaches becoming an increasing problem? Why do particular drugs work for some people and not others, who continue to struggle with tension headaches, chronic headaches, and migraines? How much of a role do genetics, the environment, and diet play in causing headaches? And what could you try if you've done everything for relief and got nowhere? In this timely book, family doctor and former headache sufferer Carole Hungerford addresses what we know about treating and preventing this common health problem, including what triggers headaches, foods and chemicals to avoid, and the latest research on the role that genetics play in causing migraines. She explores the evolutionary role of the headache, and examines which approaches to treatment work best for which types of patients. Some of us only get the occasional headache; for others, headaches dominates their lives. This book explains the science behind headaches, the possible causes, and what can be done to stop the problem. It's the one book every headache sufferer will need.
