Nervosa

From WikiMD's Wellness Encyclopedia

Nervosa

Nervosa refers to a group of eating disorders characterized by an intense fear of gaining weight and a distorted body image, leading to excessive dieting, exercise, or binge-eating followed by purging. The most well-known types include Anorexia Nervosa and Bulimia Nervosa, with Binge Eating Disorder also being closely related, though not always classified under the term "nervosa." These disorders can have severe psychological and physical health consequences.

Types of Nervosa[edit | edit source]

Anorexia Nervosa[edit | edit source]

Anorexia Nervosa is characterized by a restriction of energy intake leading to a significantly low body weight, an intense fear of gaining weight, and a distorted perception of body weight or shape. Individuals with anorexia often go to great lengths to control their weight and shape, which can significantly interfere with their lives.

Bulimia Nervosa[edit | edit source]

Bulimia Nervosa involves episodes of binge eating followed by compensatory behaviors such as self-induced vomiting, misuse of laxatives, diuretics, or other medications; fasting; or excessive exercise. Like anorexia, bulimia is associated with a preoccupation with body shape and weight.

Binge Eating Disorder[edit | edit source]

Though not always classified under "nervosa," Binge Eating Disorder is a significant eating disorder characterized by recurrent episodes of eating large quantities of food (often very quickly and to the point of discomfort); a feeling of a loss of control during the binge; experiencing shame, distress, or guilt afterwards; and not regularly using unhealthy compensatory measures (e.g., purging) to counter the binge eating.

Causes and Risk Factors[edit | edit source]

The exact cause of eating disorders like nervosa is unknown, but a combination of biological, psychological, and environmental factors is thought to contribute. These can include genetic predisposition, neurobiological imbalances, low self-esteem, societal pressures, and stressful life events or transitions.

Treatment[edit | edit source]

Treatment of nervosa typically involves a multi-disciplinary approach including nutritional counseling, psychotherapy, and medication. The specific type of treatment depends on the severity and type of eating disorder. Early intervention is associated with better outcomes.
