It is normal for nipples to secrete fluid after pregnancy and there is no need to worry too much. After pregnancy, due to changes in hormone levels, the level of lactogen increases and a small amount of lactation occurs. Pay attention to breast hygiene, scrub with warm water, wear a suitable bra, don’t wear tight clothing and don’t squeeze your breasts. If you have not had a breast ultrasound examination before pregnancy or if you have nipple overflow with fever, breast lumps, or painful breast sensation that persists without relief, you need to have a breast ultrasound examination, and if there are any abnormalities, you need to be seen by a breast surgeon and given treatment under the guidance of a professional doctor. No special treatment is needed for breast enlargement or consideration of fibroids, etc. After postpartum weaning, continue to do a good breast health check, and if there is no abnormality in the breast ultrasound, pay attention to hygiene and regular maternity checkups, lactation will increase in late pregnancy to prepare for delivery and postpartum breastfeeding.
