Breastfeeding is possible for patients with enlarged mammary glands, and enlarged mammary glands themselves do not affect breastfeeding. After a woman is pregnant, the mammary glands will show constant changes with the endocrine changes, such as the mammary glands begin to fully develop and gradually increase in size, which is a normal physiological phenomenon. After delivery, the mother enters the breastfeeding period, and during the process of breastfeeding, breast enlargement has a tendency to gradually decrease. Therefore, breast enlargement generally does not affect women’s normal breastfeeding, and no special treatment is needed during this period. Breastfeeding is good for both the mother and the baby, and can promote the recovery of the mother’s uterus and reduce bleeding. Breastmilk is the best food for babies, which is conducive to strengthening the baby’s resistance and promoting the normal growth and development of the baby. When the patient has breast enlargement can breastfeed. If the patient has severe breast enlargement, or use medication to treat breast enlargement, breastfeeding needs to be done with caution, so the patient should consult a specialist on whether he/she can breastfeed specifically.
