Anorexia Vs. Bulimia

So I have a question.

On the recovery tips it said that binging is a natural reaction to restricting. Which makes sense. Your body feels deprived. Etc.

But if that is true.. how does anorexia fit with that? Anorexics starve themselves and they don't lose it and binge.

It must go further than just being a reaction to dieting then..

Firstly, some anorexics do

Firstly, some anorexics do b/p, its call the purging subtype. There is a cross over between AN & BN & if you look at the DSM diagnostic criteria the main differences are body weight 15% underweight & no periods...Its an area I have been doing quite a lot of research on lately.

I was talking to my dr about just this yesterday, he said that if you are restricting, but not too much then the body kind of adjusts to this & will eek out survival on limited resources.
If your body weight drops too low the binge urges will come eventually, so Im told.

Another thing that happens with bulimia is that the blood sugar goes ape, which predisposes us to going round & round, b/p rest, b/p rest....the ups & down actively produce the urges to purge.

Another major factor I believe is that during starvation, the body can release natural opiates, these have the effect of making a person feel nice & calm & may also supress the appetite...Hence making the restriction easier. So I guess its about consistancy maybe?

Have you read the starvation study? It explains a lot of this.

I hope that helps & I hope I havent come across as a know it all :S

Big hugs

joblogs- Thanks for shedding


Thanks for shedding some light on that. Makes sense. I understand that for some people there is a cross-over between anorexia and bulimia, and some switch back and forth over the course of their eating disorder.

But I just wonder for the people who are solely anorexic.. or solely bulimic where the difference in personality lies. Because an eating disorder is obviously not about the food.. Idk just curiousity.
