what is anorexia nervosa?
Anorexia nervosa (anorexia for short) is a serious, potentially life-threatening eating disorder characterized by self-starvation and excessive weight loss (or lack of appropriate weight gain in growing children). People with anorexia generally restrict the number of calories and the types of food they eat.
symptoms of anorexia
- Restriction of energy intake relative to requirements leading to a significantly low body weight in the context of age, sex, developmental trajectory, and physical health.
- Intense fear of gaining weight or becoming fat, even though underweight.
- Disturbance in the way in which one’s body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or denial of the seriousness of the current low body weight.
- Binge-Eating/Purging type anorexia involves binge eating and/or purging behaviors during the last three months.
- Restricting type anorexia does not involve binge eating or purging.
NOTE: A person can meet all the criteria above except for weight loss/low body weight. This is termed “atypical anorexia” and should be taken just as seriously as anorexia. Atypical anorexia is diagnosed under the category of Other Specified Feeding or Eating Disorders (OFSED), which is one of the most prevalent eating disorders among adults today.

health consequences of anorexia
Anorexia involves self-starvation, and the body is denied the essential nutrients it needs to function normally, so it is forced to slow down all of its processes to conserve energy. This “slowing down” can have serious medical consequences:
- Abnormally slow heart rate and low blood pressure, which mean that the heart muscle is changing. The risk for heart failure rises as heart rate and blood pressure levels sink lower and lower.
- Reduction of bone density (osteoporosis), which results in dry, brittle bones.
- Muscle loss and weakness.
- Severe dehydration, which can result in kidney failure.
- Fainting, fatigue, and overall weakness.
