Is there a genetic component to anorexia?

Although thought of as a psychological problem, the eating disorder anorexia nervosa often runs in families, suggesting that it has a genetic component. Now researchers have found two genes that help determine the risk of acquiring the disease.

Is anorexia psychological or biological?

Anorexia is triggered by psychological problems that transform into biological issues. Profound physiological changes brought about by the semi starvation state cause a domino effect. The biological ramifications of the disease should be cured before psychological counseling is attempted.

What are some of the biological processes that are disrupted in the brain of an anorexic?

New research suggests that women who develop anorexia nervosa may have altered levels of dopamine in their brains. Dopamine disturbances can cause hyperactivity, repetition of behavior (such as food restriction), and anhedonia (a decreased sense of pleasure).

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].

What are some triggers that might affect the development of anorexia?

  • Difficulty expressing emotions and feelings.
  • History of being teased or ridiculed based on size or weight.
  • History of physical or sexual abuse.

Do eating disorders have a genetic component?

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.

Are there genetic risk factors associated with eating disorders?

Eating disorders such as anorexia nervosa and bulimia nervosa involve complex and interacting mechanisms. Formal genetic studies suggest that there is a substantial genetic influence for these disorders.

What factors influence the development of eating disorders?

  • Low self-esteem.
  • Depression and anxiety.

  • Environment.
  • Home Environment.
  • Socio-Economic Status.
  • Home Atmosphere.

What are the biological factors of depression?

The biological factors that might have some effect on depression include: genes, hormones, and brain chemicals. Depression often runs in families, which suggests that individuals may inherit genes that make them vulnerable to developing depression.

What other diseases can anorexia cause?

Anorexia is associated with bone health issues. This can include osteopenia, fractures, osteoporosis, and more. The longer a person lives with anorexia, the more severe these problems will be. Additionally, some bone loss stemming from anorexia can be irreversible.

What part of the brain is responsible for anorexia?

The brain region known as the right insula also seems to be altered in people with anorexia. That bit of brain helps to process taste sensations, but it’s also involved in interoception, the ability to sense one’s own bodily signals. Those skewed body signals are the subjects of Zucker’s research at Duke.
