That’s assuming you could somehow stop new microplastic from entering the body

Microplastic leeches.

I mean, there is the argument that if they bioaccumulate in the blood, it’s worth removing periodically even if it doesn’t stop new intake

No because you’re making blood from nutrients with microplastics mixed in. That’s how it would hypothetically accumulate there in the first place. If it were being filtered out of the blood by another organ then I could see a case for scraping/removal but if it’s the blood then it’s coming directly from your food and drink and will be the same ratio even after bloodletting and/or regeneration.

Let’s say you keep dripping slightly muddy water into a bucket. Over time, the mud will settle and accumulate in the bucket, while the clearer water will overflow. Now suppose you cut a slit at the base of the bucket. Now the mud will flow out through it and the water in the bucket will become less muddy, even though new muddy water is still dripping in. Here the bucket is your bloodstream, the slightly muddy water is your food, and the mud is microplastic.

That’s animal cruelty. (Feeding plastic-laden blood to leaches)

Somehow I don’t think they’d mind too much, provided you give them a nice leech habitat.

Until Socraleech comes along and they force him to suck hemlock.

That’s a special type of cruelty when victim does not mind. Like when you give a drug addict tons of heroin.

The food you consume to produce the blood also has micro plastic. Nothing changes.

Yeah buts it’s fresh micro plastic and not this stall stuff I’ve had in me for years.

Therefore it’s got new fresh chemicals to “leech” out into your blood again.

That should depend on how the chemicals accumulate though. If all the plastic ends up in your blood and never gets naturally filtered out, it could make sense. Maybe it builds up in your fat/muscles instead though, or gets filtered over time and the amount in your system is the same as the amount in what you have recently eaten, idk

It isn’t. Blood donation reduces PFASs and iron buildup (too much iron in the blood is bad). And leeches are used in certain procedures, although I haven’t heard of them being used to remove microplastics (yet).

It also works on forever chemicals. They studied levels of PFAS in the blood of firefighters (who are commonly exposed to high levels in the foam they use), and found a clear difference between those that regularly donated blood and those who didn’t

Why would you use a leech instead of a needle or something? What are they for

Amputation sites I think? The suction attracts blood flow to the area and supports healing/retention of blood vessels… I think. Neither one of us clearly can be bothered googling but that’s what I recall…

Not OP, but apparently they’re useful for when you want a continuous, slow drain of blood. The ones they breed for hospitals don’t carry disease, so you can just kinda plonk it onto the spot that you want blood out of, and replace it when it gets full

It’s less about the blood they suck out and more about their saliva. It’s a natural anticoagulant.

For skin grafts after burns; the leeches’ saliva has anticoagulants that helps blood flow through the microvasculature (tiny blood vessels) of the area. This helps promote growth of new blood vessels, as well as improve the health of the current blood vessels in the area.

TLDR: Helps tiny blood vessels in skin grafts (and other procedures), reduces failure of said skin grafts

If anybody’s wondering if there aren’t more modern medicines and treatments…

Yes, but leeches are cheap and does the job just fine

Others have already mentioned limb reattachment and anticoagulants, but if you’re interested in learning more, I highly recommend a book called Dark Banquet: Blood and the Curious Lives of Blood-Feeding Creatures. Leeches, mosquitoes, bedbugs, and vampire bats are fascinating!

A lower amount of blood to my brain might help stop the speed of a downward spiral. That or I could get diagnosed with ghosts and prescribed cocaine. Old medicine truly worked wonders.
