Blocked milk duct while breastfeeding is a common problem that can happen to any mother. This article will help you understand what blocked milk ducts are, how they usually happen, and the best way to unclog them. It also provides tips on preventing blocked milk ducts for mothers in order not to face mastitis or worse when it happens.

What is blocked milk duct?

You may have heard of blocked milk ducts before and must be wondering what they are. Blocked milk ducts are blocked tubes in your breast that prevent the excess milk from draining normally. It is usually caused by a clogged gland in your breast.

Basically, your breast is trying to tell you that it needs some help because it is producing more milk than the baby can handle. This causes a lot of pain as well as inconvenience because breastfeeding becomes difficult with all this extra pressure on your breast tissue.

Symptoms of a blocked milk duct

How do you know if you have plugged milk ducts? These are few things you can look out for to determine whether or not you have plugged milk ducts:

  • Milk blister: You may notice white breast skin which is often accompanied by a hard spot in the breast that can almost feel like a ball. It should be understood as there is too much pressure built up in your breast due to the plugged ducts, or even from mastitis (more on this later). There will be visible changes in the breast area such as swelling and redness which goes along with pain when your baby feeds.
  • Poor drainage: This is the very obvious sign you may realize while breastfeeding. It could happen in one breast or both breasts (right and left) which can coincide with the milk blister formation described above.

  • Reduced milk flow: As milk accumulates in the milk ducts or milk blister, it can cause your flow to reduce. Moms who usually do milk pumping can easily see the flow is much slower than usual or considerably less. This can be one of the most obvious indications you may have plugged milk ducts.
  • Breast lump: You may feel a small, soft bump or tender lump in your breast under the nipple that is usually tender when touched. If you situation is more serious, there is no surprise if there is a hard lump under your nipple as well.
  • Breast pain: You may also experience a lot of sharp stabbing pains in the breast while breastfeeding as well as when your baby is latched on and drinking milk from it. This can be very uncomfortable during normal activities like walking, turning over in bed or even just moving around too quickly because the breast milk ducts are blocked.
  • Breast engorgement: One or both of your breasts are very full and hard. This is because the milk ducts have become blocked preventing your body from releasing all of the built up pressure causing a great deal of discomfort.

  • Heat: The area of affected breast will feel warm and may even start to get red like a pimple that is about ready to pop. Then there might be some blockage going.
  • Mild fever: If you are unaware of already having blocked duct for 2-3 days, you may notice higher body temperature and a mild fever that last for more than 24 hours.
  • Body ache: You might also feel like you have the flu with an overall sense of fatigue, loss of appetite and maybe even some back pain too. This is because your lymphatic system which produces white blood cells to fight infection has been working overtime.

What causes clogged milk ducts?

Here are several common causes leading to clogged ducts .

  • Dead or broken skin: Some moms barely think of this case. If you have been experiencing itching, burning or irritation around the nipple area it could be a sign that dead skin is built up and blocking milk ducts in your breasts. Usually, the plug is caused by scar tissue build-up from previous breastfeeding due to some damage to breast tissue while nursing.
  • Bacterial infection: If your nipples are not carefully sanitized, bacteria can develop around or on top of your nipple which causes more pain and inflammation that leads to blocked ducts as well.
  • Breastfeeding habits: There is a quite number of frequent breastfeeding women said their baby feeds mostly on one breast side than the other breast which leads to one side being filled with more milk than the other and results in clogged duct.
  • Baby’s positioning: While breastfeeding, the way you position your baby can also cause clogged milk ducts. Baby’s mouth should be placed at the base of the nipple and not too low or high on the breast to avoid blocked milk flow.
  • Suddenly stopping breastfeeding: When you start weaning your baby, your milk drainage can not flow freely like before. Stopping breastfeeding gradually would be better than doing it in a sudden way.
  • Medications: Some medications you are taking while breastfeeding could also cause blocked ducts due to their effect on your body.
  • Temperature change: You may try avoiding hot shower or heat exposure because sudden changes in temperature can trigger plugged ducts signifying that it is the cause of clogged milk ducts.
  • Tight clothing: Wearing tight and unbreathable clothes across the stomach and breast areas will also lead to clogged milk ducts.
  • Diet: If you are eating dairy products that contain lactose or if you’re consuming too much foods with caffeine then this likely cause clogged milk ducts .
  • Lifestyle habits: This could be also considered as one major factor that can lead to plugged milk duct where you have bad sleeping patterns or do not drink enough water which results in your body being dehydrated and thus, lack of good circulation.

The answer, simply put is yes in most cases. Milk ducts are narrow tubes that carry milk from the lobules (milk-producing glands) to the nipple where it can be accessed by your baby. Sometimes these narrow tubes get clogged and will unclog themselves if given enough time; usually around five days after symptoms first appear. At that point, the ducts will be back to their regular narrow state and you can then resume breastfeeding.

How to relieve plugged milk ducts?
