R.N.
I don't know if this could be related, you'd have to see what the dr says and compare stories. My son had a birth defect called Hirshsrungs Disease. It is where a part of his intestines did not have any nerves connected to it so nothing was going through cause it couldn't push all the stuff down. Sinse birth(this is when we found it at 11 days old)he had been throwing up green stuff,was not able to have a bowel movement ,his belly was extened out (he was so bloated) that you could see every vein in his tummy and he wouldn't eat anything. I was doing some research on this Disease and I found that some people don't even know that they have it.They can go all their life and not know it. The only symptom they have is severe constipation. Don't know if this is worth mentioning to the dr. I hope you find out how to manage what ever is going on with her. Good Luck!!
