Bulimia is a kind of mental disorder that can affect anyone at any age. However, it is the young generation aged between 15 to 25 years which is most likely to get affected by this disorder. An individual affected by this disorder is most likely to go through a phase where they eat an excess amount of food in a very short period of time (binge eating) and then try to get the same food out of their body to try to not gain the extra weight.
