I struggled with the same thing after getting out of the hospital with anorexia then got sick. One of my problems was that getting food back into my system causes diaherra....which caused me to get dehydrated then back in the medical hospital....but it was my GP that was treating the medical aspect of my anorexia at the time anyway...so its good to mske sure they know what is physically going on with you.

I found out something very interesting last fall when I was caring very closely foe 3 stalluon horses that had been starved/abused during the legal process that was going on against the owner. Refeeding them is much like refeeding us after loosing massive amounts of weight with anorexia. All of the stallions suffered from stomach ulcer pain after they were starting to eat better & gain weight. The vet said that the acid in the stomach produced to digest the hay was causing the ukcer pain. I had to treat them with a new medication that helped aid their digestion along with probiotics to balance the enzymes in their gut. These stallions so reminded me of what I had done to myself only in their case it was someone abusing them (realized that in reality I had abused myself)...but being so closely involved in their refeeding process gave me understanding of the struggles I went through physically not just psychologically with my own refeeding.

That is why its important for your GP to monitor you during this time also....as the body, not just the mind is struggling
