Breast Sagging: Is Breastfeeding to Blame?

Breastfeeding your child offers numerous benefits for both mothers and babies. However, one common concern that many moms have is whether breastfeeding can cause their breasts to sag.

The fear of losing the perkiness of their breasts after pregnancy and breastfeeding can be a significant worry for some women. In order to get a complete understanding of the effect breastfeeding has on sagging breasts, let’s discuss the changes to breasts during pregnancy and breastfeeding, and breast care to minimize boob sag.

Does Breastfeeding Make Your Boobs Sag?

Breastfeeding may cause temporary changes in breast appearance due to stretching and hormonal fluctuations. However, the impact on sagging is generally mild and influenced by various factors like genetics, weight, and skincare. With care, you can minimize any potential effects.

Breast Changes During Pregnancy

Pregnancy is a transformative journey for a woman's body, and breast changes are an integral part of this process. These changes begin early on and continue throughout pregnancy, preparing the body for breastfeeding.

  • Increased Size: One of the most noticeable changes is breast enlargement. As early as the first trimester, your breasts may start to grow and become fuller. This growth is mainly attributed to increased blood flow and the development of milk ducts in preparation for breastfeeding.

  • Tenderness and Sensitivity: Many women experience increased breast tenderness and sensitivity. Hormonal fluctuations, particularly elevated levels of estrogen and progesterone, are responsible for these sensations.

  • Darkened Areolas: The areolas—the darker area around the nipples—often become larger and darker in color during pregnancy. This change is thought to aid newborns in locating the nipple.

  • Veiny Appearance: Due to increased blood circulation, the veins in your breasts may become more visible during pregnancy.

  • Stretch Marks: Some women may develop stretch marks on their breasts as the skin stretches to accommodate breast growth. These marks are typically a result of the rapid expansion of breast tissue and are not exclusive to breastfeeding.

  • Colostrum Production: In the later stages of pregnancy, your breasts may start producing colostrum, a nutrient-rich, yellowish fluid that will nourish your baby in the first few days after birth until your mature milk comes in.

Breastfeeding and Breast Changes

Breastfeeding is a natural continuation of the changes your breasts underwent during pregnancy. While breastfeeding, your breasts continue to evolve.

  • Milk Production: Breastfeeding stimulates the production of breast milk. Hormones like prolactin and oxytocin come into play to ensure your body produces an adequate supply of milk to nourish your baby.

  • Breast Fullness: In the initial days postpartum, your breasts may feel exceptionally full and may even become engorged as your milk supply adjusts to your baby's needs.

  • Changes in Nipple Size and Color: The size and color of your nipples may temporarily change during breastfeeding. Some women notice that their nipples become larger or darker during this time.

Understanding Breast Sagging

Breast sagging, often referred to as breast ptosis, is a natural phenomenon that occurs in many women at some point in their lives. It's essential to grasp the key factors contributing to breast sagging to better understand its relationship with breastfeeding.

One primary factor influencing breast sagging is the process of aging. As we age, our skin naturally loses its elasticity, and this can affect the firmness and shape of the breasts. Over time, the ligaments that support the breast tissue may weaken, leading to a gradual descent of the breasts. Aging is an inevitable process that affects women regardless of whether they've breastfed.

Genetics also play a critical role in determining breast shape and elasticity, with some women genetically predisposed to greater sagging tendencies, irrespective of breastfeeding. Additionally, weight fluctuations, particularly rapid weight loss or gain, can impact breast tissue appearance and contribute to sagging, emphasizing the importance of maintaining a stable and healthy weight for overall breast health.

Lifestyle choices can impact breast sagging as well. Smoking, for instance, can accelerate the breakdown of collagen and elastin fibers in the skin, leading to premature sagging. Additionally, excessive exposure to ultraviolet (UV) radiation from the sun or tanning beds can have a similar effect on skin elasticity.

Temporary vs. Permanent Effects

It's important to distinguish between the temporary effects of breastfeeding on breast appearance and the more permanent changes that can occur.

Temporary Effects

Most of the changes that occur during pregnancy and breastfeeding are temporary. Breast enlargement, tenderness, and changes in nipple size and color typically revert to their pre-pregnancy state once breastfeeding ends.

Permanent Effects

Breast sagging, if it occurs, is more likely influenced by factors such as genetics, aging, and lifestyle choices rather than breastfeeding alone. While breastfeeding may contribute to mild, temporary sagging, it is not the primary cause of permanent breast sagging.

Breast Care During and After Breastfeeding

To maintain breast health during and after breastfeeding and minimize any potential effects on breast appearance, consider the following care tips:

  • Supportive Bras: Invest in well-fitting, supportive bras designed for nursing mothers. These bras provide essential support and can help minimize strain on breast tissue and ligaments.

  • Hydration and Nutrition: Stay hydrated and consume a balanced diet rich in nutrients that promote skin elasticity and overall health.

  • Moisturization: Apply a good-quality moisturizer or oil to keep the skin on your breasts well-hydrated.

  • Chest Exercises: Incorporate chest-strengthening exercises into your post-pregnancy workout routine to help tone the underlying muscles, providing added support for your breasts.

  • Consultation: If you have concerns about breast sagging or other breast-related issues, consider consulting with a medical professional or plastic surgeon for personalized advice and potential interventions.

My Experience With Breastfeeding

During my pregnancy, I experienced some significant changes in my breasts that I hadn't anticipated. In fact, the first indication that I was pregnant was the changes I felt in my breasts. They became noticeably larger and more sensitive.

Along with the size increase, I also noticed my breasts looking a lot more veiny. At first, it caught me off guard, but I learned that it's a common occurrence due to increased blood flow as your body prepares for breastfeeding.

One of the most striking changes during pregnancy was the transformation of my areolas—the darker area around the nipples. They grew larger and darker, which I later discovered is nature's way of making it easier for newborns to find the nipple. It was fascinating to see how my body was preparing itself for the incredible journey of breastfeeding.

Now, as I'm still breastfeeding my baby, I can confirm that these changes haven't gone away. My breasts continue to feel different throughout the day, especially during feeds.

When they fill with milk, there's this unique sensation of fullness, and as my baby empties them through feeding, there's a noticeable relief. It's a dynamic process, and I'm amazed at how efficiently my body adjusts to meet my baby's needs.

While my breasts may have undergone some unexpected changes during pregnancy and breastfeeding, I've come to appreciate the beauty and wonder of these transformations. They serve as a constant reminder of the incredible bond I share with my baby and the nourishment and comfort I provide through breastfeeding.

It's an experience I wouldn't trade for anything in the world, and I look forward to seeing how my body continues to adapt as my breastfeeding journey continues.


Breastfeeding offers many benefits to mom and baby, and the fear of breast sagging should not deter women from choosing to breastfeed.

While there may be some temporary changes in breast appearance during and after breastfeeding, these changes are influenced by various factors, and their impact on sagging is often mild. By following healthy practices, maintaining a healthy weight, and taking good care of your breast skin, you can help minimize any potential effects on breast appearance.
