There are a few reasons why your armpits might itch when you breastfeed. The most common reason is that you have a rash or infection in the area. Other reasons include dry skin, sweat, and allergies. But for most women, it might just be down to hormones or the fact that the milk products glands are situated near the armpits.

Why do my armpits itch when breastfeeding?

Itchy on armpits is caused in part by milk production and also by work carried out in the milk glands close to armpits. The milk glands located close to the armpits can be itchy when you have a heavy let down during breast feeding. Many moms have reported breastfeeding itchiness is worst during a let down and it could just be the sensitivities are heightened by the letdown.

The itchy feeling could have been caused directly from increased blood flow or oxytocin release. Oxytocin usually releases during breastfeeding, when the hormone is producing the sensation that you feel is normal. Once baby’s mouth attaches and the let down starts the hormones can go into overdrive!

What Can I do if My Armpits itch while breastfeeding?

If you’re experiencing an itchy sensation in your armpits while breastfeeding, there are a few things you can do to help:

  • Make sure that you keep your armpits clean and dry. Wipe them down with a damp cloth after each feeding session, and use a good quality deodorant if needed.
  • Apply a cold compress to the area to help soothe any inflammation or irritation.
  • If your rash is caused by an infection, seek medical treatment as soon as possible.
  • Talk to your doctor , medical professional or lactation consultant about any other measures you can take to alleviate the itchiness.
  • Nursing moms have milk ducts under their arms, some women even leak milk from their arm pits so it’s vital that you keep this area clean and dry. If your milk let down is causing the hormonal itchiness the best you can do is just treat the itch until your hormone settles.
