Galactorrhea may be caused by which of the following factors?

Galactorrhea is the inappropriate secretion of breast milk, and one of the well-documented causes of this condition is hypothyroidism. In hypothyroidism, there is a deficiency of thyroid hormones, which can disrupt the normal hormonal balance in the body, leading to increased levels of prolactin—a hormone that plays a critical role in breast milk production. Elevated prolactin levels can stimulate the mammary glands and result in galactorrhea.

This condition highlights the interplay of endocrine functions in the body; when one hormone is out of balance, it can lead to various symptoms and issues, showcasing the significance of thyroid health in reproductive and breast health. It's essential for healthcare providers to consider hypothyroidism as a potential underlying cause when evaluating a patient presenting with galactorrhea.
