When I hear talking about forever chemicals, they are usually described as “chemicals are not affected by naturally occurring reactions, and that accumulate in the bodies of living beings”. By accumulating, they cause all sorts of health issues.
What I don’t understand is how they cause these health issues. If these chemicals do not participate in regular reactions, how do they cause issues?
I am not claiming that the research in the subject is wrong, I am missing the link between “these things don’t react with anything” and “these things still cause all sorts of health problems”.

The PFAS chemicals we know the most about are toxic at very low exposure levels to humans and wildlife. Some of them, like pfos are bioaccumulative, which means their concentration builds up in your cells over time.
Not all the toxicology is published, but PFOS scared a lot of people when they realized how low those levels were.
Medically, PFOS causes liver & thyroid damage, lowered fertility, increases obesity, hormone suppression and antibody suppression.
Each individual PFAS chemical has its own toxicology characteristics.
