Breast Changes Post-Baby? Here’s an Expert Explanation


Pregnancy and motherhood—they’re two of the most colossal life-changing, identity-shifting, soul-fulfilling, mind-blowing, exceptionally-challenging things a person can go through. And we probably don’t have to tell you, but the road is ripe with physical changes as well. 

If you’re staring down your shirt wondering what happened, here’s an expert take on exactly why your breasts may change post-baby and breastfeeding, straight from Dr. Bayati M.D., board-certified OB/GYN. Spoiler alert: It’s normal. And we have a few strategies to help you combat dramatic shifts.

Physically, what are some of the changes women can expect to see when they stop breastfeeding?

"On average, cycles return between five to nine months after birth. This can occur earlier despite breastfeeding or come much later once breastfeeding is done. It depends very much on each individual's circumstances,” Dr. Bayati explains.

And how should we expect to feel? “Women can experience a sense of return to normal with cycle return in regards to mood, libido, energy and focus. But some can also experience a declining mood immediately following a wean off of breastfeeding, especially if the wean is not gradual.”

“Metabolism rates can slow following breastfeeding wean and thus many can experience a slight weight gain. However, again, we are all different and many finally can shed the last few pounds of pregnancy weight gain only after they wean completely. No two people are alike in how they experience all the changes of postpartum,” Dr. Bayati explains. 

What's happening biologically to cause breast shrinkage?

“Breast changes are common with pregnancy and breastfeeding. During pregnancy and breastfeeding the breasts grow significantly and typically become denser. The ligaments that support your breast tissue also loosen and stretch to allow for this growth. 

After breastfeeding is done the fatty and connective tissues of your breast will again shift and change. This can lead to changes in size and shape. Some women will notice their breasts remain large, but a majority notice shrinkage. It’s important to note that the changes can also be asymmetric with different changes in different breasts,” Dr. Bayati explains. 

Plus, “genetics, weight gain during pregnancy, the number of pregnancies and even age at the time of pregnancy has an impact. Also notable, smoking will affect connective tissue and thus skin changes with breastfeeding.” 

What exactly is going on with the nipple situation?

“The nipple and areola complex, as we call it, will become larger and more pronounced in pregnancy. As the breasts get larger and the veins become so much more prominent, the nipples and areola typically darken and the oil glands surrounding the nipples may be noticed for the first time,” Dr. Bayati says.

“Following breastfeeding, the color typically lightens and the area becomes smaller and all the veins in your breasts are no longer as visible with the decrease in blood flow and prolactin hormone. Nipples decrease in size but similar to your belly button, they may never quite be exactly the same. But truly, your whole body, mind and soul is changing with each pregnancy and time.” Ah, the nipserr, tides of change. 

What are some tips to minimize the changes that may occur? 

“It is unclear if there are clinically-proven ways to minimize changes to your breast tissue, but it’s very important to know the benefits of breastfeeding. It is also important to realize that breastfeeding is very demanding and takes tremendous support and commitment especially with the first pregnancy,” Dr. Bayati advises. 

With that said, “there are things to consider that may help with some of these changes. Rapid weight gain during pregnancy can exacerbate changes. Thus, a clean diet and good exercise regimen heading into pregnancy and maintenance through pregnancy will help. Maintaining healthy, hydrated skin is important. Enhancing your diet with clean protein and collagen sources may also be helpful. Reducing trauma to the breasts from improper latches, excessive pumping, clogged ducts, mastitis, infections and gradual weaning should be considered as well.”
