What are the causes of breast sagging in unmarried women?

Generally, unmarried women may experience breast ptosis due to factors such as heredity, aging, excessive weight loss, improper bra wearing, or lack of exercise. It is recommended to visit a reputable hospital and, under a doctor's guidance, improve the condition through methods such as breast lift surgery, autologous fat breast augmentation, laser therapy, changing to a suitable bra, and increasing physical activity. The specific analysis is as follows:

1. Genetic factors: Breast shape is closely related to heredity, and some women may have a genetic predisposition to breast ptosis. It is recommended to follow medical advice and undergo breast lift surgery, which involves removing excess skin and tissue and reshaping the breast position to improve the appearance of sagging breasts. The general reference price for breast lift surgery is 10,000-60,000 yuan per session, with visible improvement typically seen within 1-3 months; however, complications such as hematoma or breast asymmetry may occur.

2. Aging: As one ages, various bodily functions gradually decline, and collagen and elastic fibers in the skin are progressively lost. This causes the chest skin to become loose and the breast tissue to shrink, ultimately leading to breast ptosis. Autologous fat breast augmentation can be performed under medical guidance by extracting fat from other body areas, processing it, and injecting it into the breasts to achieve a lifting and fuller appearance. The general reference price for autologous fat breast augmentation is 10,000-30,000 yuan per session, with visible improvement typically seen within 2-3 months; however, complications such as fat liquefaction or an uneven chest surface may occur.

3. Excessive weight loss: Rapid weight loss within a short period, especially through extreme methods such as dieting, leads to a quick reduction of fat tissue in the breasts, while the skin's contraction rate cannot keep up with the fat loss, resulting in breast ptosis. Laser therapy can be performed under a doctor's supervision; this non-invasive method involves using laser stimulation of breast tissue to promote collagen production, thus improving the firmness and elasticity of the breasts. The general reference price for laser therapy is 2,000-8,000 yuan per session, with visible improvement typically seen within half a month to one month; however, complications such as infection or scarring may occur.

4. Improper bra wearing: Wearing bras that are too large or lack sufficient support over a long period fails to effectively lift the breasts, worsening ptosis. Incorrect wearing methods, such as overly loose shoulder straps or improperly positioned back hooks, can also affect breast shape. One should choose bras with the correct size and good support and shaping functions, selecting different types for different occasions, such as wearing a professional sports bra during exercise.

5. Lack of exercise: A lack of targeted chest exercises weakens the pectoral muscles, reducing the support provided to the breasts and exacerbating ptosis. Daily routines should include chest exercises such as chest expansion movements and push-ups to strengthen the pectoral muscles and provide better breast support.

In daily life, it is important to develop good habits, such as consuming less high-fat, high-calorie foods like fatty meats and fried chicken, to avoid increasing body fat levels and worsening breast ptosis.
