Which hormone is linked to the environmental factor of BPA plastic?

The connection between BPA (bisphenol A) plastic and estrogen is rooted in the chemical structure of BPA itself, which can mimic the behavior of natural estrogen in the body. BPA is an endocrine disruptor, meaning it can interfere with the normal hormonal functions. When BPA enters the body, it can bind to estrogen receptors and exert estrogen-like effects, which may lead to various health issues such as reproductive harm, changes in hormone levels, and potential links to certain cancers.

This mimicking effect influences not just the immediate hormonal interactions but can also have broader implications on hormonal regulation and development, particularly during critical periods like puberty and pregnancy. The recognition of BPA's estrogenic activity has led to increased scrutiny of BPA-containing products and has prompted many manufacturers to seek alternatives to reduce potential health risks.

In contrast, while thyroid hormones, cortisol, and glucocorticoids play significant roles in various physiological processes, they are not directly influenced by BPA in the same way as estrogen. This distinction underscores why estrogen is specifically noted in the context of BPA exposure.
