2. ANOREXIA NERVOSA
• Anorexia nervosa is an eating disorder characterized
by food restriction, inappropriate eating habits or
rituals, obsession with having a thin figure, and
an irrational fear of weight gain.It is accompanied by
a distorted body self-perception, and typically
involves excessive weight loss.

3. Symptoms
 Refusal to maintain a normal body mass
index for their age
 Obsession with calories and fat content of food
 Food restriction despite being underweight
 Bradycardia or tachycardia
 Depression: may frequently be in a sad
 Cheeks may become swollen because of
enlargement of the salivary glands caused by
excessive vomiting
 Dry hair and skin, as well as hair thinning
 Fatigue
 Rapid mood swings

4. CAUSES
 Genetics: anorexia nervosa is believed to be highly heritable
 Addiction to the chemicals released in the brain during starving
and physical activity; people affected with anorexia often report
getting some sort of high from not eating. The effect of food
restriction and intense activity causes symptoms similar to
anorexia in female rats, though it is not explained why this
addiction affects only females.
 tryptophan and steroid hormone metabolism, which might reduce
serotonin levels at these critical sites and ward off anxiety
 Orexin; orexin is a neurotransmitter that regulates appetite and is
responsible for increasing the craving for food.
 Autoimmune system; Autoantibodies against neuropeptides such
as melanocortin have been shown to affect personality traits
associated with eating disorders such as those that influence
appetite and stress responses.

5. TREATMENT
• There is no conclusive evidence that any particular
treatment for anorexia nervosa works better than
others; however, there is enough evidence to suggest
that early intervention and treatment are more
effective.Treatment for anorexia nervosa tries to
address three main areas.
• Restoring the person to a healthy weight;
• Treating the psychological disorders related to the
illness
• Reducing or eliminating behaviours or thoughts that
originally led to the disordered eating.
