Bulimia is an eating disorder that is very dangerous.  It usually triggers when a person looks at herself as being fat and can't take to eat food normally.  A bulimic person eats food just like a normal person but vomits it after wards.  Some would feel guilty having to eat and afraid to look fat.  The person suffering from this sickness thinks that she ate too much and that there is a need to take it out through vomiting.  What other reasons are there to result to this sickness?  How can this be treated?
