 How the breast milk develops in the body

Prolactin and oxytocin are the hormones primarily responsible for production of breast milk in female, but they work through a negative feedback mechanism with oestrogen and progesterone. Prolactin hormone stimulates the production of the milk while oxytocin is responsible for ejection reflex of the breast milk.

These hormones in the body works inversely or directly proportional in the way they secreted. When prolactin increases, progesterone and oestrogen reduces in the body. However the oestrogen which is responsible for menstrual flow decreases and menstruation is generally affected.

Therefore prolactin can inhibit ovulation in a lady’s system preventing the release of eggs (ovaries) at the female reproductive system.

Irrational use of contraceptives can lead to unexpected breast milk discharge.  When a female takes a contraceptives pills when there is actually no sperm deposit into the system (uterus). The progesterone pill ingested can alter the natural hormonal secretion pattern in her body, therefore increasing the prolactin and oxytocin level causing a sudden production of breast fluid.

Consumption of some foods like millet, barley, bounce rice, coconut water, raw almonds, oatmeal, fenugreek, carrots, asparagus, yam, pea, sweet potatoes, if taken in excess over a long time can also lead to a sudden production of breast fluids.
