Let me preface this by saying that I would prefer not to discuss the psychology of bulimia in this particular thread - I have a very good knowledge of that particular aspect of the disease - I’m more interested in the physiology involved.
Most bulimics are considered normal weight or even slightly overweight, despite purging. Only patients who have a strong restrictive component to their disease (more associated with anorexia) tend to be underweight.
I personally, while not bulimic, am pregnant and barfing my damn face off. I’m still eating stuff, but it tends to come up fairly quickly; however, I’m still gaining a respectable amount of weight for a preggo lady at my stage.
So the question is this - when food is consumed, are the calories ‘taken up’ by the body almost instantaneously? Like the food hits your tummy and BLAMMO calories are absorbed? Or is it the case that bulimics binge so much food that it’s impossible to purge it all out leaving them with a calorie overload?
Thanks!
