If the milk is not completely emptied after breastfeeding, resulting in the accumulation of milk in the milk ducts and the discharge of milk when squeezed, the residual milk in the breast should be emptied as soon as possible to avoid chronic inflammatory changes in the milk ducts due to long-term stimulation of the milk ducts by the residual milk. Secondly, since the secretion of breast milk mainly depends on the elevation of lactogen or estrogen, if breast milk is extruded during the non-lactation period, endocrine hormone disorders caused by pituitary or ovarian lesions should be considered, and you should go to a regular hospital for sex hormone six and pituitary magnetic resonance examination to clarify the cause. It is an abnormal physiological phenomenon to be able to express milk after 5 years of weaning. You should seek medical attention and cooperate with a specialist to avoid serious clinical consequences.
