Milky discharge from nipples is called galactorrhea. It is not the milk production during breast feeding. It is a sign of an underlying disease. Sometimes the symptom goes on its own.
Most often its occurrence is seen in women, but can also occur in men and in infants.
It can be a result of excessive breast stimulation, side effects of medicines, pituitary gland disorder or increased level of hormone prolactin.
Hormones play a very important role in galactorrhoea that is in excessive milk production. Galactorrhea occurs due to elevation in levels of serum prolactin. Prolactin is a hormone produced by lactotroph cells of the anterior pituitary gland.
The major role of prolactin hormone is to enhance breast development during pregnancy and to induce lactation.
Galactorrhea is a condition occuring due to nonpuerperal hyperprolactinemia. This nonpuerperal hyperprolactinemia occur in cases of pituitary lactotroph adenomas which produce prolactin. These lactotroph adenomas are called as prolactinomas.
There may be other reasons also that lead to hyperprolactinemia such as pathological problems of the hypothalamic-pituitary that is the disturbance in a dopaminergic pathway. Dopamine is a protein which has the dominant influence over prolactin secretion.
Prolactin plays the very important role in stimulating breast epithelial cells, therefore, induce milk production and maintaining milk production.
Primary hypothyroidism is another major factor leading to the high production of TRH ( thyrotropin releasing hormone) ultimately leading to hyperprolactinemia.
Age / Sex of Galactorrhea
Galactorrhea is more common in females than in males.
Females who are already suffering from hormonal disturbance diseases such as amenorrhoea, oligomenorrhoea or infertility.
Galactorrhea is rare in women of postmenopausal age due to lack of estrogen hormone.
Women and males of any race can be affected.
Galactorrhea occurs more common in developing countries due to high-stress levels.

• The discharge from the nipple is analyzed to see if there is a presence of blood in the fluid.
• Blood test to check prolactin level and TSH level.
• Pregnancy test is done because it may be one of the reasons of galactorrhea.
• Medicines to decrease the level of prolactin.
• In case of tumor either medicines are given to shrink the size or surgery is done.
• If the underlying cause is a side effect of any medicine, it is recommended to immediately stop that medication.
• Medicines are given if an underlying cause is a hypothyroidism.
• If there is no relief from medicines surgery is done to remove milk ducts.
• Wear clothing that does not cause friction.
• Avoid performing breast self-examination.
• Avoid breast stimulation.
The condition of galactorrhea goes away on its own. If it persists the prognosis depends on the underlying cause.
