It's been confirmed now by testing my blood for the genetic side. Haemochromatosis, or GH (Genetic Haemochromatosis), is a genetic disorder causing the body to absorb an excessive amount of iron from the diet: the iron is then deposited in various organs, mainly the liver, but also the pancreas, heart, endocrine glands, and joints. (Note: My was 81% iron saturation level - I was informed between 30-40% would be normal, and I have an older brother on the flip side with low levels.) I have to thank my previous doc (who now no longer works for my GP surgery) for putting the request in for the test. He gave me some information and it's worked out to be true. I'm just glad they've caught it while i'm younger - the issues could be worse if not found at a later age. (Possibilities would include cirrhosis of the liver - but I'm reasonably sure I wouldn't be getting that, as it's already in place that I have a time/date for a venesection). Now I have to push to get information to my son's mum - to give her an understanding that it can be genetic although not noticed until people are 30-50 - and he's 8 - but if informed, there's something that can be done sooner to discover first if he has it, and second to put things in place if he does a bit sooner so the saturation levels don't reach so high. Gah.
