In children under 18, higher levels of lead and DEHP metabolites in the body are linked to lower levels of diastolic blood pressure, triglycerides, and fat around the waist, but it is not known...
Mechanism
Synthesis from 1 study
These chemicals might trick the body into using less energy and storing less fat, which lowers blood pressure and belly fat. But it’s not clear if this is a real benefit or just a sign that the body isn’t working right.
Most probable mechanism
When children are exposed to these chemicals, their bodies may slow down energy use and fat storage because the chemicals interfere with how cells respond to signals that normally tell them to store fat or raise blood pressure. This causes blood pressure, fat levels in the blood, and belly fat to stay lower than expected.
Lead and DEHP metabolites bind to nuclear receptors involved in lipid metabolism and vascular tone regulation, altering transcriptional activity of genes that control adipocyte differentiation and vascular smooth muscle contraction.
This receptor interference reduces the production of signaling molecules that promote fat accumulation and vasoconstriction, leading to decreased triglyceride synthesis and lower peripheral vascular resistance.
The resulting metabolic suppression reduces energy storage in adipose tissue and dampens sympathetic nervous system activity, contributing to lower diastolic blood pressure and reduced central adiposity.
