My son iron level was 7.3. He came home from college in December and when he came back in March he looked totally different he had lost at least 60lbs. He said had failed classes and was kicked out of school but didn't say anything because didn't want to let us down. So he was depressed and was staying with a friend. Now this has been going on for at least a month now spitting excessively fever headache fatigue and now he wearing adult diapers due to uncontrollable bowel movements went back to ER still contributing to the anemia. What else could be going on. And what type of specialist do I need to get him too. Primary doctor really only going on the anemia as well although I feel it's more as these other issues have started
