I have to say I don't really understand the article wholly but it all sounds like complete nonsense. Are they saying anorexia/bulimia is caused by a similar autoimmune response to Crohn's? As a sufferer of both anorexia (nervosa) and Crohn's I know what caused my anorexia, I can pinpoint all the mental triggers and I see a therapist every week who can identify them all along with me - she actually says talking to me is like talking to two people because there is me and there is anorexic me, it depends on the day as to which one wins out. I can't see antibodies doing that?! Plus I like live off soya yogurt with all the added prebiotics and I'm still not 'cured'.
I was diagnosed with anorexia 6 years ago, my Crohn's symptoms started June 2008 approximately. So how can I have been through this suggested similar autoimmune response twice? It makes no sense.
I also agree these 'it's all in your head' accusations are said in most cases without due care. Even though yes I have a mental illness, I'm more than capable of differentiating between reality and what is in my head, when I became very ill with the Crohn's granted I wasn't eating a lot but for me to lose like 16lbs in such a short amount of time was not down to the anorexia only. I'd put up with having anorexia for the rest of my life if it meant I didn't have Crohn's because the pay off would be worth it to not live with the Crohn's symptoms. Anorexia causes no physical symptoms that I don't have control over - I realise I have given control to the anorexia but most of the effects on my body could still be reversed. With Crohn's its not quite like that. I don't like the suggestion the two are related - they are clearly not in my eyes. Anorexia is a mental illness, Crohn's is not. Simple.
Erazer makes a good point, it is almost like the blog writer is looking for other excuses (maybe excuses isn't the right word) for her daughter's anorexia.
