|
Term
Approximately 60% of pituitary adenomas secrete what hormone? |
|
Definition
|
|
Term
Another cause of hyperprolactinemia is hypothyroidism. Why? |
|
Definition
Since Hypothyroidism is the thyroid slacking off, there tends to be an increase in Thyroid Releasing Hormone (TRH) in an attempt to raise the thyroid's activity. Turns out, TRH also causes prolactin release.
Increase in TRH = increase in prolactin = hyperprolactinemia. |
|
|
Term
Why would antidepressants or cimetidine ("Tagamet" - an H2 inhibitor) cause hyperprolactinemia? |
|
Definition
Because they interfere with dopamine activity.
Without DA working well, the hypothalamus is no longer inhibiting the pituitary so much, so the pituitary gets to secrete more of whatever it wants. And what it wants… is prolactin. |
|
