What are the most serious physical problems associated with purging?
The major issues with all of the purging is leeching out and depleting the body of its minerals like potassium, sodium and so on. Also causing nutritional deficits that later result in things such as losing your hair, changes in your skin, your nails and so on. It is not simply weight loss. The other is the idea that purging gets the food out of you, which it really doesn't because after a meal, a large percentage of the food is absorbed even before the vomiting occurs. So it is more carrying out the mental idea of doing something that was out of your control and now you are bringing about something to undo that.
