Long-term hyperprolactinemia consequences?

Long-term hyperprolactinemia consequences?

• A. Weight gain
• B. Galactorrhea
• C. Osteoporosis, pituitary tumors, breast cancer
• D. No long-term effects

Answer: (C)

Long-term excess prolactin disrupts the hypothalamic-pituitary-gonadal axis by inhibiting GnRH, which lowers estrogen in both women and men. Over years, reduced estrogen leads to bone loss and osteoporosis. Often this elevation is due to a prolactin-secreting pituitary adenoma, so a chronic pituitary tumor is a logical long-term consequence. Prolactin also has effects on breast tissue, and sustained high levels have been associated with an increased risk of breast cancer in some studies, making it another potential long-term consequence. While galactorrhea and weight gain can occur with high prolactin, they are more immediate symptoms rather than the chronic complications emphasized here.
