Iron overload / haemochromatosis occurs in approx 0.5% of the population of Northern European origin (and less in other ethnicities). Undiagnosed and untreated the iron will build up in the liver and other organs and cause a variety of unpleasant side effects. Venesection is the standard treatment, though I suggest that less than 0.5% of the population is not significant enough to explain the other studies.
