Do bulimics have a lot of heartburn or lots of acid symptoms?

Sounds quite likely: It is just one of the physical dangers of this eating disorder. Hopefully you have recognized this early enough to stop doing damage to your digestive system (and other organs). Do see a doctor to evaluate your gastrointestinal condition and find a good psychotherapist to help you stop your bulimic behaviors. Experienced therapists are very successful with cooperative patients. Best of luck!

Bulimia: Yes it can and it quite commonly so.
