<unk>  can take place as a result of dysregulation of certain hormones. Hormonal causes most frequently associated with<unk>  are hyperprolactinemia and thyroid conditions with elevated levels of thyroid-stimulating hormone (TSH) or thyrotropin-releasing hormone (TRH). No obvious cause is found in about 50% of cases. Lactation requires the presence of prolactin, and the evaluation of<unk>  includes eliciting a history for various medications or foods (methyldopa, opioids, antipsychotics, serotonin reuptake inhibitors) and for behavioral causes (stress, breast, and chest wall stimulation), as well as evaluation for gestation, pituitary adenomas (with overproduction of prolactin or compression of the pituitary stalk), and hypothyroidism. Adenomas of the anterior pituitary are most often prolactinomas. Overproduction of prolactin leads to cessation of menstrual periods and infertility, which may be a diagnostic clue.<unk>  may also be caused by hormonal imbalances owing to birth control pills.<unk>  is also a side effect associated with the use of the second-generation H2 receptor antagonist cimetidine (Tagamet).<unk>  can also be caused by antipsychotics that cause hyperprolactinemia by blocking dopamine receptors responsible for control of prolactin release. Of these, risperidone is the most notorious for causing this complication. Case reports suggest proton-pump inhibitors have been shown to cause<unk> .
