Biological factors There appears to be a familial link to anorexia and individuals with a family history of eating disorders, depression, or substance misuse in that these individuals are more likely to be affected.

How is bulimia genetic?

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.

Can your esophagus heal after bulimia?

Does bulimia change brain chemistry?

Women with bulimia nervosa, when bingeing and purging, are known to have alterations of brain serotonin activity and mood as well as obsessions with perfectionism. Serotonin is a neurotransmitter that helps regulate mood.

How does bulimia cause metabolic acidosis?

Patients who purge by vomiting may present with metabolic alkalosis (elevated serum bicarbonate levels) due to volume contraction. However, patients who primarily abuse laxatives may present with metabolic acidosis (decreased serum bicarbonate levels) due to loss of alkaline fluid from the bowel.

What is the most insignificant characteristic of a person with bulimia?

What is the most insignificant characteristic of a person with bulimia? The person is close to her ideal body weight. Bulimia nervosa is more prevalent than anorexia nervosa in both women and men. What is not a risk of being underweight?

How many calories does purging get rid of?
