Eating Disorder Facts
Recognition

Warning Signs & Symptoms

Eating disorders often go undiagnosed because the signs can be subtle, especially in the early stages. You cannot tell if someone has an eating disorder just by looking at them. Learning these warning signs can help you recognize a problem early — in yourself or someone you care about.

Important: Having some of these signs does not necessarily mean someone has an eating disorder. However, if you notice several of these signs in yourself or someone else, especially if they persist or worsen over time, it is worth seeking a professional evaluation. Early intervention dramatically improves outcomes.

Behavioral Warning Signs

Changes in behavior around food, exercise, and social activities:

Preoccupation with weight, food, calories, carbohydrates, fat, or dieting
Refusal to eat certain foods, progressing to restriction against whole categories of food
Appears uncomfortable eating around others
Skipping meals or taking small portions at regular meals
Food rituals — chewing excessively, rearranging food on plate, eating foods in a certain order
Withdrawal from usual friends and activities
Frequent dieting or following new fad diets
Evidence of binge eating — disappearance of large amounts of food
Evidence of purging — frequent trips to bathroom after meals, wrappers or packages of laxatives or diuretics
Excessive, rigid exercise regimen despite weather, fatigue, illness, or injury
Cooking elaborate meals for others but refusing to eat them
Wearing baggy or layered clothing to hide body shape or weight loss
