my dad has hemochromatosis since a long time and I actually was born with it. he is 78 and was in the hospital for 3 weeks and now he can not dress or wash himself. sometimes he is up and ready to go for lunch, which my mom does, but most of the time he is in bed with no energy. how long can that  go on?

Summarized question: What causes fatigue in case of hemochromatosis?
