If you're diagnosed with hemochromatosis, you may not be permitted to donate; it seems to depend on your local blood banks. There's some amount of concern that because the donation is theraputic for the donor, they may not be forthcoming about other factors that should disqualify them, if present.
Of course, if it hasn't been diagnosed and you're a regular donor, that's a happy accident.
That kinda makes sense. If you allowed them to donate even with disqualifying factors (but flushed it down the drain), it would fix the incentives. May not give enough additional blood to be worth the bother?
Donating apparently also removes microplastics from your body...
I'm curious if the donated blood is processed in a way that removes those microplastics.
Probably not, but if you're in need of a blood transfusion you have more immediate concerns.
Any references for that? What about just drinking a lot of water so you have to pee more often?
If there are any synthetic textiles in your home, it's probably a lost cause; plastic dust everywhere. Every time you eat, drink or breath, you'll be taking more in.
Are they just freefloating in blood? Capillaries are tiny and I thought micro plastics were closer to 1mm than 1micron, despite the name. Capillaries are 8-10microns.
If donating prior to high ferritin and onset of symptoms, that might be enough, but to handle the former, one needs much more frequent blood donations to push the level of stored iron level down than what donations allow. (at least in Sweden, where you can donate twice a year, but the initial treatment is biweekly iirc).
