I have this was told about 2 years ago, I got blood taken and they say even tho you have so much iron in your body you feel anaemic, so I feel tired all the time if my levels are bad. If that makes sense? I have moved countries so haven't been to get checked in a while but will now that you reminded me.
There's a lot more to the condition that they tell you or you can google. But pretty much it's 1 in 300 people and its hereditary, so no one in my family that I know has it, obviously going back generations someone would have, both my parents are carriers and all my brothers and sisters, ( all 4 ) are all carriers.
Usually 1 in 4 kids gets it, which was me! But since I have it and my husband doesn't, nor is a carrier, means neither of my kids have it smile
Hope this helps smile
