Definitely not new - as someone who was diagnosed with Haemochromatosis in 2017 - I was first prescribed phlebotomies until my general iron levels reached a level that my consultant was happy with.
Once I hit that level, I'm able to donate blood about twice a year (once every six months) to maintain (that, and a slightly changed diet to avoid high iron food)
