Anorexia Nervosa is a serious and potentially life-threatening eating disorder marked by severe restriction of food intake, resulting in dangerously low body weight. It involves an intense fear of gaining weight and a distorted perception of body size, often paired with a lack of recognition of the medical risks associated with being underweight.
Anorexia is defined by three core elements: significant restriction of energy intake leading to low body weight, an overwhelming fear of weight gain, and a distorted experience of body shape and size. These features drive behaviors such as extreme dieting, rigid food rules, or compulsive exercise, even in the face of serious health consequences.
The disorder presents in two primary forms. The Restricting Type involves weight loss through dieting, fasting, or excessive exercise without regular bingeing or purging. The Binge-Eating/Purging Type includes episodes of bingeing or purging, but differs from Bulimia Nervosa because individuals remain significantly underweight.
Starvation impacts nearly every organ system, making Anorexia the most fatal psychiatric illness. Complications may include heart issues such as bradycardia and low blood pressure, hormonal disruptions like amenorrhea or low testosterone, gastrointestinal discomfort, anemia, weakened immunity, neurological changes, and physical signs such as brittle hair, dry skin, and lanugo. Without intervention, these effects can become life-threatening.
Recovery requires a comprehensive, multidisciplinary approach. Medical stabilization often comes first to address malnutrition and correct dangerous imbalances. Nutritional rehabilitation helps restore weight and normalize eating patterns, while therapy—such as Family-Based Treatment for adolescents or CBT-E for adults—targets underlying thought patterns and behaviors. Medications may be used to treat co-occurring anxiety or depression.
With consistent, specialized support, full recovery from Anorexia Nervosa is possible.
