What Causes Clogged Milk Ducts During Breastfeeding?

What Is a Clogged Milk Duct?

A clogged (or blocked) milk duct happens when milk can’t flow out properly, leading to:

  • Localized swelling, pain, and heat in the breast
  • A firm lump that may feel tender
  • In some cases, redness or discomfort during feeding

If left untreated, it may progress to mastitis (breast infection) or even form an abscess.

Common Causes of Clogged Milk Ducts

1. Inadequate Milk Removal

  • Poor latch or shallow sucking
  • Baby falls asleep early during feeding
  • Short, frequent feeding sessions may not fully empty the breast

2. Infrequent or Irregular Feedings

  • Skipping or delaying feeds leads to milk accumulation
  • Skipping night feeds increases the risk of congestion

3. Favoring One Side

  • Consistently nursing from the same breast can leave the other engorged
  • Uneven milk removal increases blockage risk

4. Oversupply of Milk

  • Some mothers produce more milk than the baby needs
  • This can lead to backed-up ducts if not effectively drained

5. Pressure on the Breast

  • Tight bras, baby carriers, sleeping face down
  • These can compress milk ducts and block flow

6. Maternal Stress or Fatigue

  • Affects oxytocin release, the hormone responsible for milk let-down
  • Stress can slow milk flow and lead to stasis

Signs of a Clogged Milk Duct

  • A firm, painful lump in the breast
  • Localized warmth, redness, or swelling
  • Tenderness that persists after feeding
  • Slower milk flow or reduced output on that side
  • Baby may struggle or get fussy nursing from the affected breast

These signs should be addressed promptly to prevent mastitis or infection.

How to Relieve and Prevent a Clogged Duct

1. Nurse More Frequently

  • Offer the affected breast every 2–3 hours
  • If baby doesn’t empty the breast fully, pump or hand-express

2. Apply Warm Compresses

  • Use a warm towel or take a warm shower before feeding
  • This helps soften the lump and promote flow

3. Gentle Breast Massage

  • Massage from the clogged area toward the nipple using gentle, circular motions
  • Doing this while baby is latched can enhance drainage

4. Try Different Nursing Positions

  • Position baby so that their chin points toward the clogged area for better milk removal

5. Rest and Stay Hydrated

  • Drink plenty of fluids
  • Adequate rest supports milk production and flow

When to See a Doctor

Contact your healthcare provider if:

  • Pain, lump, or redness worsens after 24–48 hours
  • You develop fever, chills, or flu-like symptoms
  • You feel increasingly weak or unwell
  • Milk flow stops completely from the affected breast

These could be signs of mastitis or a developing abscess—early treatment is important.
