The consequences of untreated eating disorders are serious and can be life-threatening. Eating disorders are associated with a number of physical and mental health problems, including malnutrition, electrolyte imbalances, hormonal problems, heart conditions, and psychiatric conditions. Untreated eating disorders can also lead to social isolation, substance use disorders, and suicide. According to a study published by the Journal of Eating Disorders, anorexia nervosa has the highest mortality rate of any psychiatric disorder, with a standardized mortality ratio of 5.86. If you or someone you know has an eating disorder, please seek professional help immediately by contacting your local care management organization.
