What causes girls' inverted nipples?

As a woman, you should pay attention to the problem of inverted nipples, because many women are prone to inverted nipples in life. Some of the reasons are pathological and some are primary. For example, the smooth muscle hypoplasia of the nipple and areola usually manifests this symptom. In life, you should also pay attention to prevention, choose a suitable bra, and avoid squeezing.

1. Pathological causes

1. Primary, the main cause of nipple inversion

(1) Hypoplasia of the smooth muscles of the nipple and areola: The nipple has 15 to 20 openings of the lactiferous ducts, and the lactiferous ducts are surrounded by smooth muscle fibers. The inverted nipple is pulled inward by the muscle fiber bundles surrounding the lactiferous ducts and inserted into the nipple dermis. The texture of these muscle bundles is significantly different from that of the lactiferous ducts.

(2) The lactiferous ducts themselves are underdeveloped: The underdeveloped lactiferous ducts fail to become ductalized and appear as cords.

(3) The lack of supporting tissue under the nipple is also a cause of inverted nipple.

2. The main causes of secondary nipple inversion are usually secondary to breast tumors, inflammation, trauma, or traction of scars after breast surgery, or sagging of huge breasts.

2. Prevention:

1. Any female immediate family members, such as mothers and aunts, who have inverted nipples should be the focus of prevention. After a baby girl with a genetic predisposition is born, the mother can gently pull the small nipple outward 1 to 2 times a day. Be careful to be gentle and ask an experienced person to do it. In this way, you can see the baby's nipples protruding from the skin in the shape of green beans or small discs, and the chance of nipple retraction in the future will be greatly reduced.

2. Pay attention to your clothes. Underwear should be made of cotton and should be changed and washed frequently and exposed to sunlight. If the nipples show signs of redness or cracks, the underwear should be steamed and sterilized, and girls should not use bras too early.

3. Prevent extrusion. Underwear and bras should be appropriate and not too tight. For girls with larger breasts, more attention should be paid to the looseness of the breasts. For girls who have the habit of sleeping prone, it is necessary to correct this habit in time to prevent the nipples from being squeezed, so as not to aggravate the degree of nipple retraction.
