What Are Eating Disorders?
Eating disorders, such as anorexia nervosa and bulimia nervosa, are serious mental health conditions characterized by disturbed eating behaviors. They can have severe medical consequences and often require professional intervention to address.
Define anorexia nervosa and bulimia nervosa
Anorexia nervosa signifies a grave eating disorder typified by an extreme dread of weight gain and a negative perception of one’s self-image. This condition compels individuals to substantially limit their food intake, perceiving themselves as overweight despite being underweight.
Those affected with anorexia commonly resort to extreme measures to control their weight and form, which may critically compromise their wellness. Contrarily, bulimia nervosa is defined by periodic episodes of overeating followed by purging to restrict weight increase.
This recurring sequence of consuming large quantities of food within a limited period, then striving to expel the consumed food through forced vomiting, fasting, extreme exercise, or laxative use can be just as damaging.
The Genetic Factors Behind Eating Disorders
