Generally speaking, it is normal to have unusually large breasts after pregnancy, but it is not normal if it is caused by disease.
During pregnancy, the placenta secretes a large amount of estrogen to stimulate the development of mammary gland ducts and a large amount of progesterone to stimulate the development of mammary gland follicles. During the first few weeks of pregnancy, pregnant women often feel swelling of the breasts, or a tingling sensation and tenderness, and after 8 weeks of pregnancy, the breasts increase significantly, which is due to an increase in the number of mammary gland ducts and follicles, fat deposition, and connective tissue congestion.
So under normal circumstances, pregnant women’s breasts will get bigger after pregnancy. However, if the pregnant woman suffers from breast fibroadenoma and other diseases, it may also lead to breast enlargement after pregnancy, which is abnormal. At this time, it is necessary to consult a doctor in time, improve the breast ultrasound and other examinations, in order to clarify the cause, and according to different causes of the corresponding treatment.
