question: My daughter was diagnosed with a rare metabolic disorder through a newborn screening called MCAD. She is missing an enzyme which helps metabolize fats. Her body utilizes glucose as it's main source of energy. She can't fast for long periods of time and if she is unable to eat for an extended amount of time due to illness she is hospitalized and given an IV of D10. I am wondering what the long term prognosis is for her. She takes a daily supplement to help breakdown fat and waste in her body something that normal peoples body's do naturally.  I'm wondering if she will have any long term liver issues or what her life will be like as she is older?
