Adolescents exposed to a combination of common environmental chemicals like phenols, pesticides, and phthalates have a significantly higher likelihood of developing MASLD, a liver condition, with two...
Mechanism
Synthesis from 1 study
When teens are exposed to multiple chemicals from plastics and everyday products, their immune system gets activated, causing inflammation in the liver. This inflammation, combined with how these chemicals interfere with fat processing and energy production, leads to fat building up in the liver....
Most probable mechanism
Toxic chemicals from plastics and personal care products enter the body, trigger immune cells to release inflammatory signals, and disrupt how the liver manages fats and energy. This causes fat to build up in the liver, and when inflammation continues, it damages liver cells, leading to a more serious condition called MASLD. The more of these chemicals a person is exposed to together, the worse the effect becomes.
Phthalate and bisphenol A metabolites enter the bloodstream and activate immune cells, increasing circulating white blood cell counts.
Activated immune cells release inflammatory signaling molecules that promote chronic low-grade inflammation in the liver.
Inflammatory signals disrupt normal liver cell function by altering gene pathways that control fat synthesis and breakdown, leading to excess fat accumulation.
Bisphenol A binds to hormone receptors in liver cells, further impairing mitochondrial energy production and increasing oxidative stress, which worsens fat buildup and cell damage.
Combined exposure to multiple chemicals amplifies these effects beyond what any single chemical can cause, resulting in progressive liver fat accumulation and inflammation.
Sedentary behavior and low physical activity reduce the body’s ability to clear liver fat and suppress inflammation, allowing chemical-induced damage to progress unchecked.
