If the amount of clear fluid squeezed out of the nipple is relatively small and there is no pain or discomfort in the breast, it is considered to be a normal discharge. The mammary gland is a secretory organ, and a small amount of secretion will be discharged through the ducts and nipples. Squeezing the nipple with a small amount of clear, white fluid is normal. If the amount of fluid squeezed out is large and there is pain in the nipple and breast, it is considered to be caused by inflammation in the ducts of the breast, so pay attention to the cleanliness of the nipple and take oral antibiotic medication. If you squeeze out clear liquid or milky white liquid after breastfeeding, it is also considered to be a sign of milk accumulation, most of which will slowly absorb on its own. Some patients with cystic hyperplasia of the breast can also be manifested by nipple overflow. If nipple overflow occurs, try to go to the hospital first to confirm the diagnosis and then treat the symptoms if necessary.
