Thanks so much once again for your caring and educational posts, also thanks for not making me feel a real 'idiot'.
Her weight loss came about four weeks after the constipation started, she and some friends came down with a stomach bug, she got the vomitting but no diarrhea - we were hoping it would clear the impaction but no! She had a violent bug for 24 hours and virtually had about 4 hours where she wasn't vomitting, we kept pushing the fluids even though she couldn't keep anything down, just so she didn't become dehydrated. We had been to the Dr the day before and she weighed 3.5kg heavier (we had checked her on our scales as well). What followed was 8 months of trying to get some weight on her. I think the big thing is that she was always such a big bread, cereal and pasta eater and she has had to go gluten free, which is different in taste and she is still getting used to g/f foods. She has put on a about a kilo and a bit. She was never a big child so the weight loss is noticeable and of concern. But her energy levels are good and she is able to do sports and function completely normally during the day unless she has been 'glutened' it is the pain at night that is just such a ....pain :-) Thanks once again Pauline
