Bulimia nervosa is a type of eating disorder. People with bulimia nervosa can’t stick to a healthy eating pattern. They tend to binge, that is, eat a lot at once. This makes them feel guilty and out of control so they then panic and punish themselves by starving, making themselves sick, taking laxatives or over-exercising.
This can lead to a number of physical problems including tooth decay, constipation and intestinal damage, as well as heart and kidney disease. Telltale signs of bulimia nervosa include making excuses to avoid eating in company or rushing to the lavatory after a meal.
