Causes of breast sagging and expansion

Breast sagging and expansion may be caused by ligament laxity after breastfeeding, decreased skin elasticity with age, insufficient support due to sudden weight loss, improper underwear, and lack of protection during exercise.

1. Ligament relaxation after breastfeeding:

Breast tissue hyperplasia during pregnancy and frequent milk engorgement during lactation can cause overstretching of Cooper's ligament, the suspensory ligament of the breast. After weaning, the glands atrophy, but the ligaments are difficult to fully retract, resulting in loose skin under the breasts. It is recommended to wear supportive nursing bras during breastfeeding and enhance support through chest muscle exercises such as push-ups after weaning.

2. Skin aging with age:

Decreased estrogen levels reduce collagen synthesis, causing breast skin to thin and elastic fibers to break. This condition mostly occurs after the age of 35 and may be accompanied by increased wrinkles around the areola. Appropriate supplementation of phytoestrogen foods such as soy products, and massage with lotion containing vitamin E can delay the process.

3. Excessive weight fluctuations:

When you lose more than 20% of your body weight in a short period of time, the rapid shrinkage of fat cells will prevent the skin from shrinking. Commonly seen in people who are on a diet to lose weight, the breasts may appear like an orange peel. It is recommended to increase the thickness of the pectoralis major muscle through strength training to provide internal support for the breasts.

4. Wrong choice of underwear:

Long-term wearing of bras with cups that are too small and straps that are too thin will compress breast tissue, causing the breasts to shift toward the armpits. Displacement of the steel ring may directly damage the suspensory ligament. You should choose a full-cup style, make sure the underwire fits the lower edge of the breast completely, and the shoulder strap width is no less than 1 cm.

5. Insufficient sports protection:

During high-intensity exercise such as running, the breasts will sway in an "∞" shape, and a single strenuous exercise can cause micro-tears of the suspensory ligament. Those who do not wear sports bras have a 2.4-fold increased risk of sagging within 3 years. For high-intensity exercise, you need to choose compression sports bra, which can reduce breast shaking by more than 53%.

Daily exercises such as kneeling push-ups or dumbbell flyes can be performed to strengthen chest muscles.； The buoyancy of water during swimming can reduce the burden on ligaments ； Consume foods rich in high-quality protein and vitamin C to promote collagen synthesis ； Avoid lying on one side for long periods of time to compress your breasts while sleeping. If obvious sagging occurs along with shoulder and neck pain, it is recommended to consult a doctor to evaluate medical options such as sling surgery or prosthetic implantation.
