My niece has been hospitalized most of her life. She will be 20 years old tomorrow and is in the hospital with no one who knows how to help her with this condition. Is there a Dr. at the Mayo Clinic who can help her? She has been vomiting for 7 or more days and can’t get any nutrients in her body. She has been on IV fluids forever. She just got out of the hospital 2 weeks before this episode began. Can someone help us, help her feel better?
