Document Summary
Health hazards, medical evaluation, and the role of the physician. Poor peripheral circulation, resulting in cold extremities. Inability of the heart to increase oxygen delivery to the tissues during exercise, which can result in a cardiac event. 58% of skeletal mass is acquired during puberty and adolescence. Low bone density (osteopenia); study 2000: 92% of anorexics had osteopenia. Porous bones (osteoporosis); study 2000: 38% of anorexics had osteoporosis. This compromised bone density results in frequent stress fractures in ed (7x higher in anorexics) Erosion of dental enamel (in purging anorexics: usually after purging 3x+ a week for 4+ years) Anorexics who recover from their eating disorder have significantly improved bone density compared to active anorexics, but never regain their pre-disorder bone density. Reduced fertility or infertility (study: 16% of those who went to an infertility clinic were anorexic) Miscarriage/intrauterine death (6x more likely than non-eating-disordered pregnant women) Anorexia nervosa: gastrointestinal tearing/bleeding of the esophagus (in purging anorexics)
