Breasts are made of ligaments and connective tissue — not muscle. This means, when it comes to breast ptosis (the technical name for breast sagging), we’re at the mercy of things like the elasticity of our tissues and ligaments, how old we are, and genetics. Events like pregnancy and rapid weight loss can also have an impact.
However, it’s not all out of our control. Quitting smoking, strengthening the pectoral muscles behind your breasts, and wearing a supportive sports bra during high impact activity can all be effective prevention measures. That said, sagging is completely natural and does not have a negative impact on health. A healthy mix of preventative measures, finding the proper support, and learning to accept the body’s natural changes over time are all important parts of dealing with breast ptosis.
While some sagging is genetic, a portion of ptosis can occur from excessive bounce and stretch. Over time, stretching of the skin can lengthen Cooper’s ligaments (the fibers that anchor breasts to the chest wall). When those ligaments lose their elasticity, you’re left with a sagging effect.
Larger breasts will naturally bounce and stretch more than smaller breasts, which is in part why bigger busts are at increased risk of sagging. And, of course, breasts are at their bounciest during a high intensity workout. Investing in a properly fitting and secure sports bra is a great way to slow the effect of sagging over time.
Though breast sagging is ultimately a natural part of owning boobs, the following bra styles can enhance a more relaxed breast shape:
In general, any bras with side support structure help to redistribute the breast tissue forward into a more natural perky shape.
Age has a few implications on breast sagging. For starters, the longer you’ve been alive, the more time gravity has to weigh down on breasts. Hormonal changes come with age too, especially after menopause when the body decreases the amount of estrogen it produces. Less estrogen means a decrease in fat and decreased tissue elasticity, which can contribute to a more relaxed appearance.
Breast involution, one of the most well-known causes of drooping, can happen when the milk-producing part of a woman’s breast is no longer necessary. It can occur whether or not you actually become pregnant or breast feed. This is most commonly experienced post-weaning, directly after pregnancy if you do not nurse, or during menopause.
Heavier breast tissue will weigh down on skin. After significant fat loss, skin doesn’t always recoil, which can result in sagging.
Women with larger breasts can experience increased stretching of the Cooper’s ligament, which happens thanks to our good friend gravity. In general, smaller breasts will experience less sagging.
Just like during rapid weight loss, a rapid change in breast size during pregnancy can impact breast ptosis. Breasts will become larger during pregnancy and will typically shrink either after pregnancy or after the baby is finished breast feeding. If a woman does not breast feed, that size decrease will happen more rapidly, which can have a bigger effect on breast sagging. During breastfeeding, that size change can occur more slowly, which may minimize the sagging effect.
Smoking can negatively impact skin elasticity, and the tissues and ligaments in your breasts are not exempt. If you’re looking for a reason to quit or cut back on smoking, this is a great one to add to the list.
Truth: Sagging is caused by stretching of tissues and ligaments. Bouncing and excessive movement can stretch tissues and ligaments over time. Therefore, especially if you have a larger chest, a supportive daily bra and sports bra can minimize stretching over time. However, it’s not entirely correct to say that a lack of a bra is what causes breast ptosis.
Truth: Rapid changes in breast size is what really impacts breast laxity. While breasts will generally shrink after pregnancy, breastfeeding can help slow down that change in size, which can decrease the effect of sagging.
Truth: Breasts are constantly changing! Weight changes, hormonal changes and pregnancy can all impact the size and shape of breasts.
