The role of genetics in eating disorders has been a subject of research for decades. Studies of families and twins have confirmed that eating disorders run in families because of shared genetic factors.
Why do people become anorexic?

- Avoidant/restrictive food intake disorder (ARFID)
- Other specified feeding and eating disorder (OSFED)
Is there a genetic component to anorexia?

Can I have anorexia if I’m not underweight?
A person does not need to be underweight to have anorexia. Larger-bodied individuals can also have anorexia. However, they may be less likely to be diagnosed due to cultural stigma against fat and obesity. In addition, someone can be underweight without having anorexia.

What biological factors affect mental health?
Biological factors include genetics, prenatal damage, infections, exposure to toxins, brain defects or injuries, and substance abuse. Many professionals believe that the cause of mental disorders is the biology of the brain and the nervous system.
What are biological influences on behavior?
A growing body of evidence suggests that biological factors such as genes, hormone levels, brain structure, and brain functioning influence the development and trajectory of conduct problems in youth.
Could biology play a role in the development of an eating disorder?
Genetics have seen recent evidence in studies between twins, in the link between eating disorders and genes. These studies have shown that eating disorders may be hereditary and those individuals who have a family member with an eating disorder, are 7-12 times more likely to develop one as well [1, 3].
Do genetics play a role in bulimia?
Familial and twin studies have supported a genetic predisposition to eating disorders, with significant linkage on chromosome 10p in Families with Bulimia Nervosa. A 1998 study estimated the heritability of Bulimia to be up to 60 percent, with the remaining variance attributable to the individual-specific environment.
When does anorexia nervosa typically begin?
The eating disorders anorexia nervosa and bulimia nervosa, respectively, affect 0.5 percent and 2-3 percent of women over their lifetime. The most common age of onset is between 12-25. Although much more common in females, 10 percent of cases detected are in males.
Is anorexia a genetic or a behavior associated pathology?
The eating disorders anorexia nervosa and bulimia nervosa traditionally have been viewed as sociocultural in origin. However, recent behavioral genetic findings suggest substantial genetic influence on these disorders. Molecular genetic research of these disorders is in its infancy, but initial results are promising.
Can you diagnose yourself with an ED?
