HELP PLEASE!!!!!!

Hey everyone I need help!!! I have a friend whos always feeling tired, sick,vomitting, she doesn't gain much weight, and she's never wants to eat cuz it makes her sick or vomit. She's 17 and has ulcers, she's anemic (sp) (iron defficient) and she has a lung problem that doctors here cant figure out exactly what it is and say it could cause empysema (sp). They keep doing blood tests and other tests and jsut give her new medication. Is there anyone that can help and try to figure out what can be done and a doctor to see that can help with the lung problem. This what I know .... Ulcers can cause anemia and uclers can be treated! but what do you do about the acid in the body taht keeps causing the ulcers? ... Once the ulcers are taken care of, iron defficiency is easier to treat and can be can cured over time. Acids in her abdamen area, the digestive area cause her uclers, I'm assuming beacuse of the ulcers shes aneamic (sp). The lung issue, not sure, it could be related or not. I need info on all this if someone could please help, it'd be much aprreciated. Please!
