Researchers found a liver fibrosis link to a chemical used in dry cleaning

Liver disease isn't only about alcohol and weight — researchers are investigating an overlooked chemical exposure. When doctors talk about liver damage, alcohol, viral hepatitis and metabolic disease usually dominate the conversation.

The useful part

Liver disease isn't only about alcohol and weight — researchers are investigating an overlooked chemical exposure. When doctors talk about liver damage, alcohol, viral hepatitis and metabolic disease usually dominate the conversation. study found that adults with detectable blood levels of tetrachloroethylene — also called perchloroethylene or PCE — had substantially higher odds of significant liver fibrosis.

How it works

  • Still, it raises a broader question: how much of liver health is shaped by chemicals people encounter outside the doctor's office?
  • PCE is a volatile solvent historically used in dry cleaning and in some industrial settings.
  • The study cannot prove that PCE caused the scarring, and exposure was measured at one point in time.
  • PCE has been used because it is a powerful solvent PCE is effective at dissolving grease, which made it useful in dry cleaning, metal degreasing and other industrial applications.

What to take from it

Environmental chemicals receive far less attention.
