What is the Origin of EDC Exposure?

The term is derived from environmental toxicology, where research established that ubiquitous chemicals like phthalates, BPA, and certain pesticides possess structural similarity to natural steroids. Exposure quantifies the dose of these xenoestrogens or anti-androgens entering the biological system.

What is the Mechanism of EDC Exposure?

EDCs often operate via competitive antagonism or agonism at steroid hormone receptors, such as the estrogen or androgen receptors, thereby shifting the downstream transcriptional landscape. Some EDCs impair hepatic cytochrome P450 enzymes responsible for hormone inactivation, leading to prolonged or inappropriate hormone signaling duration. Chronic low-level exposure can thus subtly but persistently shift the endocrine set point away from optimal function.

EDC Exposure

Meaning

EDC Exposure signifies the quantifiable intake or absorption of Endocrine-Disrupting Chemicals, which are exogenous agents capable of interfering with any aspect of hormone action. Within hormonal health, this includes substances that mimic, block, or alter the synthesis, transport, metabolism, or elimination of endogenous steroids and thyroid hormones. Identifying this exposure is crucial for uncovering underlying dysregulation.
