I don't think bulemia would be the only cause of a potassium deficiency. I had an aunt who was hospitalized a couple of times for extremely low potassium. She was in her 70s, definitely not bulemic, just wasn't eating right. After her bouts I always have bananas in the house.
Given Terri's history of serious dieting, I can see how the low levels might occur by just erratic eating, not necessarily bulemia. imo

Bulemia is a form of malnutrition, when you get down to brass tacks. It's just that the cause of the malnutrition is psychological (Self image problems, depression, etc). But, I guess the popular belief, on one side of this fight, is that an abusive husband caused a potassioum deficency, heart attack, lack of oxygen, brain damage and (sort of) vegitative state, so I bow to the experts here.
