What causes nipples to become larger and harder?

There are various reasons for nipple enlargement, most of which are changes in the body's female hormones. For example, after pregnancy, the body's female hormone metabolism increases, which can cause nipple enlargement. Many women often feel breast pain and hardness. What is going on?

1. Breast pain during puberty: It usually occurs between the ages of 9 and 13. The pain and swelling will subside on its own after the first menstruation.

2. Breast pain in the early stages of menstruation: Many women experience breast swelling, hardening, and tenderness before their menarche. In severe cases, the breasts will swell and become uncomfortable when slightly vibrated or impacted. This is because the level of estrogen in the body increases before menstruation. Fibrocystic breast disease is a common breast disease in women. The nomenclature of this disease is very confusing, with aliases such as lobular hyperplasia, dysplasia of the breast, and fibrocystic disease. It was once called diffuse cystic mastitis, but in fact there is no inflammatory change in this disease, so it is not suitable for use. The characteristic of this disease is the proliferation of breast components, which shows abnormalities in structure, number and tissue shape, so it is called cystic hyperplasia or mammary structure abnormality.

Edema of breast tissue. Excessive blood accumulation in the tissue spaces or renal ducts is called edema. Normally there is only a small amount of fluid in the renal duct. If blood accumulates in the renal duct, it is called hydrops, such as hydrops in the peritoneum (hepatic ascites), hydrops in the pleural cavity (pleural effusion), hydrops in the pericardium, hydrops in the cerebral ventricles, and hydrops in the scrotum. Edema fluid is generally interstitial fluid. Depending on the amount of protein it contains, it can be divided into exudate (exudat), whose density is greater than 1.018, and transudate (transudat), whose density is less than 1.015. caused by. After menarche, the shift may resolve.

3. Breast pain during pregnancy: Some women experience breast pain around 40 days of pregnancy because the embryo and fur secrete a large amount of female hormones, estrogen and prolactin, which leads to breast enlargement. In severe cases, the pain may last throughout the pregnancy and does not require treatment.

4. Breast pain after giving birth: Breast distension, lumps and pain often occur 3 to 7 days after giving birth. This is mainly due to mammary lymph node retention, venous overflow and interstitial edema. Excess blood accumulates in tissue spaces or renal ducts, which is called edema. Normally there is only a small amount of fluid in the renal duct. If blood accumulates in the renal duct, it is called hydrops, such as hydrops in the peritoneum (hepatic ascites), hydrops in the pleural cavity (pleural effusion), hydrops in the pericardium, hydrops in the cerebral ventricles, and hydrops in the scrotum. Edema fluid is generally interstitial fluid. Depending on the amount of protein it contains, it can be divided into exudate (exudat), whose density is greater than 1.018, and transudate (transudat), whose density is less than 1.015. And it is caused by blocked breast tube.

5. Breast pain after abortion: This is because the pregnancy is suddenly interrupted, and the body's estrogen level drops sharply, causing the newly developed breasts to suddenly stop growing and developing, resulting in breast lumps and breast pain.

6. Breast pain during intercourse: This is related to the physiological changes in the breasts during sexual intercourse. For those with sexual apathy or disharmonious marital life, because their sexual needs cannot be met, the hematoma and swelling in the breast are not easy to dissipate, or they do not dissipate completely. Persistent hematoma can cause breast pain.

Women do not need to worry about this, but if the swelling and pain do not ease for a long time, or even become more severe, or if when touching the breast, you find a lump with unevenness, unclear edges, and poor mobility, you should go to the hospital for examination and treatment as soon as possible.
