Prolactin is a hormone produced by the pituitary gland and plays a crucial role in milk production in women after childbirth. It also influences other bodily functions in both men and women, including fertility and the immune system.
Testing prolactin levels can be useful in diagnosing various conditions, such as unexplained headaches, visual disturbances, infertility, or problems with the menstrual cycle. It is also relevant for women experiencing difficulties with breastfeeding.
Prolactin levels can indicate pituitary gland health and assist in diagnosing conditions such as prolactinoma (a benign tumor of the pituitary gland), hypothyroidism, or other conditions that affect hormone balance.
A high prolactin level may indicate a prolactinoma, hypothyroidism, or other health issues such as liver disease, kidney disease, or polycystic ovary syndrome (PCOS). It can also be associated with certain medications or physical stress.
Low prolactin levels are generally less of a concern and are less common. However, they may suggest an underlying pituitary disorder or damage to the pituitary gland.
