Lipedema (or lipoedema) is a chronic lymphatic disorder in which abnormal levels of fat build up disproportionately in certain areas of the body, most commonly the hips, bottom and legs. Almost exclusively affecting women, who may seek help for years only to be met with ongoing anti-fat stereotyping, its significant life-changing impact has only recently been recognized, clinically and in terms of research funding. Even though research is now accelerating, there is still much left to be discovered. This book brings together the current knowns, unknowns and conjectures as a comprehensive resource for researchers, clinicians and patients seeking a roadmap to potentially improving the lives of up to 17 million women in the US and 350 million worldwide.
