Does breastfeeding cause the breast to sag?

Breastfeeding, a natural process wherein a mother nourishes her baby with breast milk, has been practiced since ancient times. It is a well-known fact that breastfeeding offers numerous benefits to both the mother and child, including strengthening the baby’s immune system and promoting bonding between mother and child. However, many women have concerns about how breastfeeding may affect the appearance of their breasts.

The perception that breastfeeding causes the breasts to sag is a prevalent concern among expectant and new mothers. Various factors contribute to breast sagging, such as age, genetics, weight fluctuations, and the number of pregnancies a woman has had. While it is true that breastfeeding can cause temporary changes in breast shape and size, there is limited scientific evidence suggesting that it directly leads to permanent sagging.

To address these concerns, it is essential to understand the anatomy of the breast. Breasts consist of glandular tissue and fat, connected by ligaments. During pregnancy, the breasts prepare for lactation, and as a result, the glandular tissue expands, causing the breasts to become larger and fuller. Once breastfeeding is initiated, these changes become more pronounced, and the breasts may increase in size further.

Despite these fluctuations, experts believe that breastfeeding alone is not a direct cause of breast sagging. Instead, the changes in size and shape during this time are primarily governed by hormonal factors and the natural aging process. As women age, the skin’s elasticity reduces, and the ligaments that support the breasts may stretch, leading to a more droopy appearance over time.

Maintaining healthy habits during pregnancy and postpartum may help minimize any concerns about breast sagging. Wearing a supportive bra throughout pregnancy and breastfeeding can provide additional support and help alleviate discomfort. Regular exercise, which includes strength training exercises for the chest and back muscles, can also promote overall breast health and contribute to improved breast appearance.

In conclusion, while breastfeeding may result in temporary changes to the size and shape of the breasts, there is limited scientific evidence supporting the notion that it directly causes permanent sagging. Factors such as age, genetics, weight fluctuations, and the number of pregnancies play a more significant role in breast sagging. By taking care of their overall breast health and practicing healthy habits, women can embrace the benefits of breastfeeding without undue concern about the long-term appearance of their breasts.

Does breastfeeding cause the breast to sag?

The question of whether breastfeeding causes the breasts to sag is a common concern among new mothers. Sagging breasts, also known as breast ptosis, refer to the downward displacement of breast tissue. Many women worry that breastfeeding may accelerate this natural process, resulting in less firm and perky breasts.

Does breastfeeding cause the breast to sag?

One of the common concerns among women considering breastfeeding is whether it can cause their breasts to sag. The truth is, many factors contribute to breast sagging, and while breastfeeding may play a role, it is not the sole cause. Let’s explore the relationship between breastfeeding and breast sagging in more detail.

Changes to the breasts during breastfeeding

When a woman breastfeeds, her breasts undergo several changes to support the production and delivery of milk. These changes include increased blood flow, enlargement of milk ducts, and expansion of glandular tissue. These natural processes can temporarily alter the appearance of the breasts.

During breastfeeding, the breast tissue may feel fuller and heavier. The increased volume and weight of the breasts can stretch the skin and ligaments that support them. However, it is important to note that these changes are usually temporary and reversible.

Factors influencing breast sagging

While breastfeeding can cause temporary changes to the breasts, long-term sagging is influenced by various other factors:

  • Age: As women age, their skin loses its elasticity, making it more prone to sagging.
  • Genetics: The genes we inherit from our parents play a significant role in determining the characteristics of our breasts, including their shape and firmness.
  • Pregnancy: Pregnancy itself can lead to breast changes, including stretching of the skin and ligaments, which can contribute to sagging.
  • Weight fluctuations: Frequent weight gain and loss can affect the breast tissue’s elasticity and contribute to sagging.
  • Smoking: Studies have shown that smoking can accelerate the aging process of the skin, including the breasts, leading to sagging.

Therefore, it is important to recognize that breastfeeding alone is not the primary cause of breast sagging. It is a combination of various factors that contribute to the changes in the breasts’ appearance over time.

The role of good breast support during breastfeeding

While breastfeeding itself may not directly cause breast sagging, inadequate breast support during this period can exacerbate the effects of other factors. Wearing a well-fitting, supportive bra can help minimize the stretching of skin and ligaments, and provide additional support to the breasts.

It is recommended to opt for a nursing bra that offers proper coverage, adjustable straps, and good support. Investing in a quality nursing bra can make a significant difference in maintaining breast shape and minimizing discomfort during breastfeeding.


While breastfeeding can lead to temporary changes in the breasts, such as fullness and heaviness, it is not the sole cause of breast sagging. Factors such as age, genetics, pregnancy, weight fluctuations, and smoking all contribute to long-term breast sagging. By understanding these factors and providing adequate breast support, women can help maintain the appearance and comfort of their breasts while breastfeeding.

According to a study conducted by the American Society of Plastic Surgeons, 89% of women who breastfed experienced changes in the shape and size of their breasts, but these changes were not solely attributed to breastfeeding.


1. Can breastfeeding cause the breast to sag?

Contrary to popular belief, breastfeeding itself does not cause breasts to sag.

2. Why do breasts sag after pregnancy and breastfeeding?

During pregnancy, breasts typically enlarge due to milk production. After breastfeeding, the mammary glands shrink, leading to a loss of fullness and potential sagging.

3. Are there other factors that contribute to breast sagging?

Yes, besides pregnancy and breastfeeding, age, genetics, smoking, gravity, weight fluctuations, and inadequate support can also contribute to breast sagging.

4. How can I prevent breast sagging while breastfeeding?

Using a well-fitting supportive bra, moisturizing the breast skin, and maintaining a healthy weight can help minimize the potential for breast sagging.

5. Will wearing a bra while breastfeeding prevent sagging?

Wearing a bra during breastfeeding primarily helps with comfort and support, but it may not entirely prevent breast sagging since hormonal changes and natural breast tissue changes are the primary factors involved.

6. Should I be concerned about breast sagging before breastfeeding?

Pre-pregnancy breast shape and firmness can vary among individuals, but breastfeeding alone is not a reason for concern about future sagging.

7. Can exercises or chest exercises help prevent breast sagging?

Exercises that target the chest muscles, such as pectoral exercises, can help improve overall chest tone, but they cannot prevent or reverse breast sagging completely.

8. Will breast sagging improve after I stop breastfeeding?

After weaning, your breasts may gradually regain some firmness, but the extent of improvement varies among individuals.

9. Is there any non-surgical treatment available for breast sagging after breastfeeding?

Non-surgical treatments like wearing supportive bras, using moisturizers, and performing exercises for the chest muscles can help improve the appearance of sagging breasts.

10. When should I consider surgical options for breast sagging?

If you are unhappy with the appearance of your breasts after breastfeeding, surgical options like breast lift or augmentation may be considered. Consulting with a qualified plastic surgeon is recommended to discuss the best course of action.


In conclusion, there is no conclusive evidence to support the claim that breastfeeding causes the breast to sag. Several studies have shown that factors like age, genetics, pregnancy itself, and weight fluctuations have a more significant impact on breast sagging than breastfeeding. While breastfeeding may lead to temporary changes in breast shape and size, these changes are primarily due to the hormonal fluctuations and increased blood flow during lactation, rather than breastfeeding itself.

It’s important to note that the benefits of breastfeeding for both the mother and the baby far outweigh any potential concerns about breast sagging. Breastfeeding provides numerous health benefits, such as boosting the baby’s immune system, reducing the risk of infections, and even lowering the mother’s risk of specific cancers. Additionally, postpartum exercise, maintaining a healthy weight, and wearing supportive bras during pregnancy and breastfeeding can help minimize any changes in breast appearance. Ultimately, it is essential to prioritize the well-being and health of both the mother and the baby, rather than worrying about the potential impact of breastfeeding on breast sagging.
