We’ve all heard of eating disorders like anorexia and bulimia, but there are a lot of other food-centric disorders that are a little less well known … and chances are, you know someone who has one:

Orthorexia – A fixation with healthy or righteous eating and the avoidance of foods that have been deemed “unhealthy.”

Pregorexia – Extreme dieting and exercising while pregnant to avoid the traditional weight gain that comes along with pregnancy.

Binge Eating – Compulsive overeating, often to deal with negative emotions or stress.

Anorexia Athletica – An addiction to exercise.

Drunorexia – Restricting food intake in order to reverse those calories for alcohol and binge drinking.
