Return to Eating Disorder Index

Not an official eating disorder, but the topic has gathered the interest of researchers.
May be related to a type of obsessive-compulsive disorder triggered by an auto immune process involving bacteria or viruses and parts of the nervous system.
May be related to pediatric infection-triggered auto immune neuropsychiatric disorders (PITANDS) and pediatric autoimmune neuropsychiatric disorders associated with streptococcus (PANDAS)

Suspected when symptoms and behaviors typical of anorexia nervosa appear suddenly in a young child, or when symptoms and behaviors in a young child worsen quickly with no other explanation

And when the child has had a recent respiratory, throat, or other infection.
Antibiotics, antivirals, and/or vaccines may be part of the treatment, either after refusal to eat appears or as prevention.
The first step in treatment is a thorough evaluation done by a pediatrician who is familiar with PITANDS and PANDAS research.
