causes of bulimia nervosa
Bulimia Nervosa-Cause. The cause of bulimia is not clear, but it probably results from a combination of genetics, family behaviors, social values (such as admiring thinness), and other things that can put someone at risk (such as perfectionism).our risk for bulimia increases if your parent, sister, or brother has the condition. But family history may be only part of the cause. Stressful life events such as moving, divorce, or the death of a loved one can trigger bulimia in some people.
According to Gelder, Mayou and Geddes (2005) bulimia nervosa is prevalent between 1 and 2 percent of women aged 15–40 years. Bulimia nervosa occurs more frequently in developed countries and in cities, with one study finding that bulimia is five times more prevalent in cities than in rural areas.
