The phrase
"high prolactin" refers to a medical condition where the level of a hormone called prolactin is abnormally high in the body. Prolactin is mainly responsible for breast milk production in women, but it also has other roles in both men and women. When prolactin levels are elevated, it can cause various symptoms such as changes in menstrual periods, breast milk production in non-pregnant women or men, reduced fertility, and sometimes even affect bone health.
