Overview
A milk bleb is a small, white, raised spot that appears on the nipple, typically during breastfeeding. It is caused by a blocked milk duct or accumulation of milk under the skin, resulting in a tiny blister. Although usually harmless, milk blebs can cause discomfort or mild pain while nursing.
In Korea, lactation consultants and pediatric/obstetric specialists provide guidance on preventing and treating milk blebs to ensure continued breastfeeding and comfort for both mother and baby.

What is a Milk Bleb?
A milk bleb is essentially a tiny blister or spot on the nipple formed when a milk duct opening becomes partially blocked, trapping milk under the skin. This creates a small, firm, white or yellow raised area that can make breastfeeding uncomfortable.
Symptoms Associated with Milk Bleb
The main symptoms include:
➔ Small white or yellow spot on the nipple.
➔ Pain or tenderness during breastfeeding.
➔ Mild redness or swelling around the spot.
➔ Temporary reduced milk flow from the affected duct.
➔ Occasionally, baby may have difficulty latching due to discomfort.
Causes / Possible Causes
Milk blebs develop due to blocked nipple ducts or local irritation.
Common Causes
➤ Improper latching during breastfeeding.
➤ Trauma or friction on the nipple.
➤ Accumulated milk that cannot flow freely.
➤ Cracked nipples or minor nipple injuries.
Other Contributing Factors
➤ Infrequent feeding or skipped sessions.
➤ Oversupply of milk leading to duct congestion.
➤ Tight clothing or bras causing pressure on the nipple.
Risk Factors
➤ First-time mothers or new breastfeeding sessions.
➤ Poor breastfeeding technique or improper latch.
➤ History of nipple trauma or infection.
➤ Babies with tongue-tie or difficulty latching.
Complications
Milk blebs are usually benign but may lead to:
➤ Temporary pain during breastfeeding.
➤ Localized inflammation or tenderness.
➤ Rarely, secondary infection if left untreated.
➤ Difficulty for baby to feed comfortably, which may affect milk supply.
When Should I See My Doctor?
Consult a healthcare professional if:

Most milk blebs can be managed at home or with simple clinical interventions.
Home Care & Relief
