Girls and women are more likely to have bulimia than boys and men are. Bulimia often begins in the late teens or early adulthood. Factors that increase your risk of bulimia may include: Biology. People with first-degree relatives (siblings, parents or children) with an eating disorder may be more likely to develop an eating disorder, suggesting a possible genetic link. Being overweight as a child or teen may increase the risk. Psychological and emotional issues. Psychological and emotional problems, such as depression, anxiety disorders or substance use disorders are closely linked with eating disorders. People with bulimia may feel negatively about themselves. In some cases, traumatic events and environmental stress may be contributing factors. Dieting. People who diet are at higher risk of developing eating disorders. Many people with bulimia severely restrict calories between binge episodes, which may trigger an urge to again binge eat and then purge. Other triggers for bingeing can include stress, poor body self-image, food and boredom.
