Diagnosing an eating disorder begins by determining the difference between a healthy concern about nutrition and an obsession. Someone who is working toward a healthy body will be focused on diet and exercise, but will remain flexible. For someone with an eating disorder, something as little as an unhealthy snack can cause extreme anxiety. Healthy individuals take time to plan fitness and nutrition, while those with a disorder make fitness a preoccupation throughout most of the day. A warning sign of an eating disorder is having thoughts about diet and exercise that affect everyday life, including work and school.


A number of red flags may appear when it's time to eat. These include:

  • Avoiding eating with others and social situations that involve food
  • Making excuses for not eating, including having a big meal previously
  • Unusual eating behavior like cutting food into tiny bites or pushing it around on the plate
  • Disappearing to the bathroom after a meal

An individual who has an eating disorder may also take a large amount of laxatives and diet pills. In the case of bulimia or binge eating disorder, the person may eat in secret and hide high-calorie foods.

Physical Signs

One of the biggest physical signs of an eating disorder is a sudden and dramatic weight gain or loss. An individual with an eating disorder may attempt to hide this by wearing layers or loose clothing. Other physical symptoms include lightheadedness, sometimes to the point of fainting, fatigue, headaches, and trouble concentrating.
