Long-term consequences of hyperprolactinemia?

Long-term consequences of hyperprolactinemia?

• A. Aplastic Anemia
• B. Galactorrhea
• C. Osteoporosis, pituitary tumors, breast cancer
• D. Weight gain

Answer: (C)

Chronic elevation of prolactin disrupts the hypothalamic-pituitary-gonadal axis by suppressing GnRH, which lowers estrogen (and testosterone) levels over time. This estrogen deficiency drives bone loss, leading to osteoporosis as a key long-term consequence. Prolactin-secreting pituitary adenomas (prolactinomas) are a common cause of persistent hyperprolactinemia, so a pituitary tumor is another relevant long-term association to recognize. Prolactin also acts on breast tissue, and long-standing hyperprolactinemia can be linked to increased breast cancer risk in some contexts. These elements together—bone density loss, underlying pituitary tumor involvement, and potential breast cancer risk—best represent the long-term consequences among the options. Aplastic anemia is not typically connected to hyperprolactinemia, and weight gain is not a defining long-term consequence in this scenario.
