People who are anorexic do not eat. They usually begin by dieting and often end by starving. They are intensely afraid of being fat. No weight is low enough. They always feel fat. Their view of their body is distorted and even when emaciated, they see themselves as overweight.
Anorexia is a life-threatening disease. People who fail to eat are usually depressed, irritable, anxious, and inflexible. They begin to isolate and lose their friends and family.
They suffer from emotional fatigue, physical weakness, headaches, dizziness, chest pain, abdominal pain, low back pain, faintness, constipation, a feeling of fullness even after eating only a little, dry skin, and being too cold. Eating disorders have the highest mortality rate of any mental illness.
