According to the causes of the formation of large and small breasts, they can be divided into congenital and acquired large and small breasts.
Congenital chest enlargement
It is usually caused by physiological reasons, that is, the sensitivity of both breasts to estrogen and progesterone stress in vivo is different, and one breast develops more obviously.
Acquired bust
1, pathological:
Some acquired diseases, such as mastitis, breast hyperplasia, chest tumor and other pathological reasons cause bilateral chest asymmetry. In this case, large and small breasts need to actively treat related diseases first.
2. Non-pathological:
Chest deformation caused by improper wearing methods of underwear and underwear, poor sleeping habits and posture, insufficient protection of chest during lactation, and poor posture.
The difference between the breasts of adult women is within 1 cup, which is within a relatively normal range, so don't be too nervous. If the size of the breasts on both sides is very different, and the difference between the left and right is more than two cups, it is a more serious situation.
The size of the chest can be judged by visual inspection, or you can refer to the horizontal circumference data of the left/right chest.
Tips:
Transverse circumference: the length of a unilateral breast passing through the nipple from the side profile to the middle profile.
If the outline of the chest is not clear, you can gently press the breast when measuring, and then measure it after the outline is obvious.
Acquired non-pathological thorax and causes of thoracic formation
1, wear a bra with too small capacity/too shallow cups.
Wearing a bra with too small/shallow cup for a long time will lead to uneven fat growth, resulting in different degrees of deformation of both breasts (auxiliary breast/armpit/fracture/upper hemisphere skin stretching/breast volume down/chest position down/drooping), thus forming large and small breasts.
2. The bra is not worn correctly.
After wearing a bra, the chicken's heart is not straight/the shoulder strap is inconsistent/the cup is skewed, and the stress on both sides of the breast is uneven, resulting in uneven fat growth on both sides, resulting in different breast sizes.
3. Bad sleep habits and posture.
Some girls are used to sleeping on their side or lying flat since childhood, which leads to the oppression of different forces on both sides of the chest for a long time. In adolescence, it will lead to inconsistent development on both sides of the chest, which may lead to permanent breasts. In adulthood, this long-term oppression will lead to the displacement of fat, which may cause the breast to be non-permanent.
4, pregnancy and lactation hormone influence and improper protection.
During pregnancy and lactation, the breasts are enlarged under the influence of hormones, and the lack of underwear or underwear support is not inclusive enough, which may lead to the aggravation of breast sizes or sizes; Improper protection during lactation causes breast inflammation or breast duct blockage, resulting in different breast sizes; Habitual unilateral breastfeeding can also cause large and small breasts.
5. Bad posture.
Such as hunchback and scoliosis.
Methods of improving big breasts and small breasts
1, improvement scheme of congenital large and small chest
Most of the breasts of adolescent girls are temporary, and most people will gradually tend to be the same size on both sides after adulthood. If the congenital chest size is still seriously inconsistent with the size of the left and right breasts in adulthood, it is very difficult to recover and can only be corrected by surgery.
2, the day after tomorrow to improve the size of the chest.
