What is 'non-purging' bulimia?

Barton Blinder, MD (Clinical Professor, Dept. of Psychiatry) gives expert video advice on: What is an 'eating disorder'?; What is 'bulimia'?; What is 'purging'? and more...

With bulimia we actually consider three behaviors or three mechanisms as being non-purging. One is the use of medication, for instance stimulants over the counter, diet pills. The other is fasting, gross fasting, for instance not eating the whole day after a binge. And then finally, exercise, if you want to use the word, exercise, purging, just the idea of blowing off calories, the mental idea that occurs in the mind of the individual that by exercising they are essentially blowing off calories and undoing the damage that they did from the binge the other day. But technically exercise, the use of drugs to inhibit appetite and gross fasting are really non-purging when compared to vomiting, laxatives and diuretics.
