What are some of the health problems associated with anorexia nervosa, and binge-eating disorders?

death: Ryan multiple consequences leading to increased mortality include hypokalemia or low potassium followed by cardiac arrhythmia or abnormal rhythm of the heart usually followed by death.

Starving & other: The symptoms of anorexia are mostly related to starvation or malnutrition. They can be quite severe including heart failure, loss of bone strength, dehydration, loss of menstruation. Binge eating (eating too much at one sitting) is not really associated with symptoms other than weight gain. Binge eating and vomiting (bulimia) is associated with health problems that are due to the vomiting.
