They may appear sickly or what others may consider too thin. They have an unhealthy relationship with food and eating and a distorted body image, believing they are fat when they are not.

While malnutrition and not maintaining a healthy weight for your age and size are common signs of anorexia, people who are not underweight can also struggle with the disorder. It is not always possible to recognize that someone has anorexia simply by looking at them. 

There is a range of physical, psychological, and behavioral signs and anorexia symptoms to watch out for that can help pinpoint the disorder that is present.
