Can stress cause high prolactin levels?

Neuroendocrine Changes. There is some evidence that functional hyperprolactinemia may be due to stress-induced neuroendocrine changes of dopamine and serotonin, thus affecting prolactin release [35]. REM sleep rebound, a behavioral coping mechanism to stress, has been found to be mediated by prolactin [36].

Is high level of prolactin curable?

Prolactinoma and hyperprolactinemia are not life-threatening. The worst side effects of medications usually go away after treatment. Infertility caused by high prolactin levels can be reversed once prolactin levels return to normal. Your quality of life will remain high even if you need long-term treatment.
