Hi. My 13 year old granddaughter was in a serious accident with multiple injuries, internal and external. 3 weeks ago she was diagnosed with SMA was given a feeding tube. They have replaced the tube 3 times, she is still losing weight, she weighs 76 lbs down from 100. She cannot eat by mouth without extreme nausea that leads to vomiting unless her Dad empties her stomach. And her feed tube backs up into her stomach. Now this evening, blood and tissue are coming back through her g tube. Please, we are very scared for her. Can Mayo help her? The dr. here seem unconcerned. Please, any advice would help. Thank you
