Bulimia is often hard to recognize because individuals struggling with the disease do not tend to be at an extreme weight—high or low. However, if a person takes in a significant amount of calories at a time, as in a dozen candy bars at one time, for instance, then purges by making himself or herself vomit, taking laxatives or enemas, fasting or exercising to the extreme, he or she may have bulimia. If asked, there is a good chance that he or she will deny that fact. Parents and loved ones concerned for their children and their children's health should speak to a health care professional, such as their children's pediatrician, about the child's eating behaviors.
