Eli5: How do micro plastics get out of our bodies?

804 viewsBiologyOther

I know a lot of people say they don’t but based on what iv seen we consume LOTS of micro plastics iv even seen a study that says we eat a credit cards worth a week if that’s true then there must be some way for our body to remove them since otherwise we’d have too much plastic in us I also heard that there is plastic in our livers and testicles . How does our body remove all of that and how much would donating blood help?

It cant. Thats what makes then possibly such a terrible thing to discover inside the human body. As far as science knows they just accumulate. We don’t yet know the true consequences of this as this has only recently been confirmed, but there is also no known mechanism by which they become removed.

Microplastics have been found in every type of bodily tissue and organ. It’s been found in breast milk, semen, blood, every layer of skin, muscle, fat, and all of our organs. Our body doesn’t deliberately remove it because it’s inorganic and isn’t seen as a threat. Some gets removed just by being caught in normal waste removal processes, but that’s about it. If you live in the modern world, it’s essentially impossible to prevent microplastics from entering your body, and our body doesn’t have a specific process for removing them.

So far the only method to reduce the amount of micro plastics in the body are quarterly blood donations. Red cross should really advertise this lol

Donating blood seems like the only for sure effective way as of now. You lose the blood, body creates more blood, less micro plastic concentration in your blood.

This got me curious so I tried to do some googling and found this https://www.sciencedirect.com/science/article/pii/S2666911022000247#:~:text=Abstract,et%20al.%2C%202021) first thing that popped up and to summarize, the eating a credit cards worth of plastic every week is hugely exaggerated and they estimate we eat about a credit cards worth of plastic every 23,000 years. This makes sense to me because if it’s true that we can’t get rid of microplastics in our bodies and we eat a credit cards worth of plastic every week then we would all be dead by now.

There are so many different types of plastic all with different properties in how they affect the body.

We poop out most of it back out, just as with anything that the body aren’t designed to absorb, it’s just going to act like a tiny bit of additional fiber.

A small amount does get absorbed because the semi permeable membranes in our digestive system aren’t perfect at distinguishing everything and these get into bloodstream. These then get into other organs in the body, and these are the ones that causes concerns. 

Some of those might get caught by the immune system and removed by the body just as any natural foreign unknown particles that our body doesn’t know what to do with. 

The most concerning are ones that have chemical structure that is similar to existing molecules that confused our body into using them up, but they don’t function properly because they aren’t similar enough and don’t act the same as the molecules they’ve been confused with. These causes various effects that are currently not very well understood.

Supposedly some organization was trying to do a study on the effects of microplastics on the human body but they had to cancel the experiment because they couldn’t find a single person that didn’t already have micro plastics in them to use as a control group.

If u think having something made from the waste product of making diesel fuel in your bloodstream and organs is normal and fine, then i have nothing to say to you. Just drinking from plastic containers have been shown to affect our hormone levels. What do u think it will do if its inside us permanently?

Did you see the study about micro plastics and testicles?
