Milk is coming out of my breast, I did a pregnancy test and I'm not pregnant. What can be the cause?

Sorry about your experience. One reason you might be experiencing Milk coming from your breast is over secretion of Prolactin. It is medically referred to as Hyperprolactinemia. Hyperprolactinemia is a state characterized by high levels of a hormone called prolactin in the blood. Prolactin is produced by the pituitary gland and plays a vital role in the development of the breasts during pregnancy.


While hyperprolactinemia is considered perfectly normal during pregnancy and breastfeeding, it can occur at other times due to disease and medication use. Hyperprolactinemia can affect both woman and men, resulting in irregular menstrual periods and erectile dysfunction, among other things.

Other causes may include:


Hypothyroidism (low thyroid hormone levels)
Cirrhosis of the liver
Chronic kidney failure
Antidepressants (Anafranil, Norpramin)
Antipsychotics (Haldol, Zyprexa, Risperdal)
Antihypertensives ( Verelan, Calan, Covera-HS, Isoptin)
Antinauseals (Reglan, Primperan, Lexapram)
Acid H2 blockers (Tagamet, Zantac)
Estrogen
