Eating disorders are psychological illnesses defined by abnormal eating habits that can negatively impact physical and mental health. The most common types are anorexia nervosa, bulimia nervosa, binge eating disorder, and OSFED. Eating disorders most often affect people ages 12-24 and can be caused by insecurity about appearance or lack of confidence from those around them. Anorexia involves extremely low body weight from food restriction and fear of weight gain. Bulimia involves binge eating followed by purging. Binge eating disorder involves frequent overeating episodes. Complications range from medical issues to relationship problems and even death if untreated. The best solution is visiting a psychologist, dietitian, and doctor for treatment
