Haemachromatosis
Any abnormal liver function tests - ask your doc to check for haemachromatosis please. Its a hereditary disease not often picked up until some level of damage has been sustained - totally unnecessary as its easily managed without medication.
I have a sibling who needed both hips replaced before the age of 40 and has chronic arthritis due to this condition being undiagnosed for far too long.
Medics assumed abnormal liver tests were due to excess alcohol consumption despite the fact that he's teetotal. (yes really)
