Did you know clogged ducts aren’t actually caused by thickened milk or a physical “blockage”? The latest evidence shows the main culprit is inflammation in the breast tissue. This swelling slows milk flow, making it feel like there’s a blockage.
What does a “clogged duct” feel like?
A tender lump in the breast.
Swelling or redness in one area.
Slower milk flow on that side.
But here’s the truth: It’s not really a “clog” at all.
Researchers now understand that:
It’s not thickened milk blocking the duct.
The issue is inflammation in the breast tissue.
Inflammation causes swelling, which slows milk flow.
It’s more about treating the inflammation, not “clearing a blockage
So what is the recommended treatment?
Gentle Milk Removal
Nurse or pump as usual to encourage flow—but avoid over-pumping or harsh squeezing.
Reduce Inflammation
Take ibuprofen to ease swelling and pain.
Apply cool compresses between feedings.
Warmth Before Feeding
A warm compress before latching can help milk flow more easily.
Avoid these common myths:
MYTH: You need to “massage out the clog.”
TRUTH: Aggressive massage can damage tissue and worsen inflammation.
MYTH: Milk “gets stuck” because it’s too thick.
TRUTH: Milk consistency isn’t the problem—it’s the swelling that is restricting flow and can cause thickening of the milk.
When should you get help?
Reach out to a healthcare provider if:
Symptoms last more than 48 hours with appropriate treatment.
You develop a fever, chills, or flu-like symptoms after 48 hours of appropriate treatment.
Pain becomes severe and unmanageable
How can you prevent clogged ducts?
Nurse or pump as usual to avoid milk stasis. DO NOT pump extra to “keep the breast empty”. This will increase inflammation.
Ensure your baby is deeply latched to ensure an effective milk transfer.
Avoid tight bras or clothing that compresses the breast.
Breastfeeding doesn’t have to be painful. If you’re experiencing these issues or suspect mastitis, let’s work together to get you feeling better!
