What Causes Sagging Breasts and What You Can Do to Prevent It

We are sorry to deliver the unfortunate news, but all breasts tend to sag after some time. While some lucky women experience a barely noticeable sag, others are far more affected. So, what are the main causes behind sagging breasts?

Although we immediately connect breast sagging with pregnancy and breastfeeding, that isn’t the only cause (though it is a prominent one). There is a number of things we do on a daily basis which contribute to sagging.

Pregnancy  or Breastfeeding

Let’s start with the cause we already briefly mentioned – pregnancy and breastfeeding. When we are pregnant, our breasts go through various changes. In most cases, they grow in order to prepare for breastfeeding. Once we give birth, our breasts get filled with milk, which enlarges and stretches the skin even more.

Once you stop breastfeeding, the breast milk dries up, and your breasts may seem small, empty, and saggy. However, these changes can happen even if you decided to skip breastfeeding.

During pregnancy and the postpartum period, a woman’s body goes through many different changes.

Once the experience is over, your breasts can remain bigger, go back to their previous state, or become smaller.

If your breast tissue shrinks, but your skin remains stretched, then your breasts will look saggy.

Number of Pregnancies

Every time you are pregnant, you go through the same process.

Your breasts enlarge, get filled with milk, and then (hopefully) return to their previous state.

So, the number of times you have been pregnant may have a significant impact on the look of your breasts.

The more children you have, the more your breasts will stretch. Still, that doesn’t have to be true for all women.

Some women may experience a lot of sagging even after being pregnant only once. That depends on other factors too; we will address those shortly.


Genetics plays a major role in most things regarding our bodies; that goes for our breasts as well.

The genes we get from our family will determine the size, shape, and strength of our breasts, as well as our body weight.

If our mother, grandmother, or aunt have large, saggy breasts, chances are that we will have them too.

On the other hand, if women in our family have small breasts with a rounder bottom, we might get lucky as well. Although we won’t enjoy a full cleavage, we will have a better chance to hold the shape of our breasts after having children.

Unfortunately, we can’t change our genetics as much as we would like to. There are some things which could help us fight unwanted changes, such as dieting and exercise, but those work only to a certain degree.

Rapid Weight Gain and Weight Loss

Great fluctuations in your weight can contribute to sagging breasts. If you keep gaining and losing 10 pounds, that won’t make a big difference.

However, gaining a lot of weight will definitely stretch your skin; at the same time, losing a lot of weight in a short time period might cause your breasts to droop because the skin won’t have enough time to shrink.


We all know how unhealthy smoking is; but did you know that it can ruin your cleavage? Smoking makes your skin lose its elasticity. Furthermore, it makes the skin around your breasts look damaged and stretched. So, smokers are more likely to develop sagging breasts.


Eventually, the ligaments which make up the breast tissue stretch and lose elasticity; that leads to reduced fullness as the underlying support becomes weaker.

Unfortunately, there isn’t much that can be done to fight time; it catches up with all of us sooner or later.

Many women notice a big change in their breasts during menopause.

Lack of Support

Although we sometimes like to let our breasts be free, proper support is crucial for your breasts’ lift and shape. It might not seem important now, but proper support will make a huge difference in years to come.

We recommend getting professionally fitted for a supportive bra; that is especially important for those who love exercising.

UV Exposure

We know how important sunscreen is, but we often neglect our breasts when we are out in the sun. It’s essential that we use sunscreen on them too; that will protect your skin from becoming dehydrated, damaged, and eventually saggy.

How to Prevent Sagging Breasts

There are so many factors which can contribute to sagging breasts; we can’t combat them all but we can try to prevent it from happening.

Avoid Smoking

Trying to quit smoking can be challenging; however, it can be rewarding.

Besides doing a great thing for our overall health, it can help our breasts keep their shape for a longer time.

Lose Weight Gradually

Once you decide to change your body, motivation can be of great help. But, if we are too motivated and we start losing too much weight over a short period of time, your skin won’t have enough time to shrink.

That could leave you with saggy breasts (and other body parts too). So, you should take it slow. Plus, it’s much healthier for you to lose weight gradually.

Keeping breast skin moist with a proper moisturizing lotion can prevent breasts from sagging

Use a Moisturizer and Sunscreen

Dry or dehydrated skin neither feels nor looks good. Also, it is unhealthy. You should regularly moisturize your skin; that will allow it to stretch and shrink more easily than dry skin. When you are pregnant or in the process of losing weight, that is especially important.

Also, you should always wear sunscreen when we spend time outdoors; even when clouds cover the sun. UV rays can damage your skin and eventually cause your breasts to sag.

There are many safe breast enhancement creams that can serve a double purpose and that is to keep your breast skin moist and healthy as well as reverse the effects of sagging and aging breasts.

Wear a Supportive Bra

Your breasts are supported and lifted by ligaments; over time, gravity pulls our breasts and stretches those ligaments.

To prevent sagging, you should wear a supportive bra (especially when you are exercising, or when you are pregnant or breastfeeding). That will help prevent the ligaments from stretching, and keep your skin from sagging.

Final Thoughts

Even though breast sagging is inevitable, that doesn’t mean you should act like we have no say in how the process goes.

There are many things which you can’t completely control, but you can still make noteworthy changes which will postpone the sagging.

When it comes to breast sagging, a few healthy habits can make a big difference in the long run.
