Many young mothers' breasts are plump and well developed, but after weaning their children, they begin to shrink gradually. After examination by the doctor, there is no organic disease, but I don't know why. Breast atrophy after weaning is common in gynecology. After pregnancy, there will be hyperplasia of mammary glands, congestion of blood vessels, increase of breast fat and breast re-growth. When breastfeeding, breast enhancement will make the breasts bigger. After weaning, the breast will return to the state before pregnancy, the breast will shrink, the skin will relax and the skin will sag. To reduce this change, you can try the following methods: 1. When feeding, both breasts have equal opportunities. Don't only recognize one breast to feed, the order should take turns. For example, the right breast follows the left breast this time, and the left breast follows the right breast next time. This will not cause the breasts to be one big and one small when recovering. 4. Hold the breast with a suitable bra when feeding. By practicing chest, you can enhance the strength of pectoralis major and lift the front breast. 3. Use a suitable bra after weaning to strengthen chest exercise. 4. Reasonable nutrition during pregnancy, don't increase your weight too much, and don't increase your breast fat too much, so as to avoid postpartum breast atrophy and relaxation. Pregnancy, childbirth and breastfeeding are all important milestones in a woman's life and an indispensable part of her whole life. However, anything meaningful will leave traces, and it is impossible to keep the body unchanged. Mental health and spirit are always full of youthful vitality, which is the most important thing. The common situations are as follows: First, most women lose body fat and weight because of their great physical consumption and hard work in taking care of their children during lactation. In addition, they do not pay attention to breast protection during and after lactation, which leads to breast atrophy. Second, breast atrophy is caused by the decrease of female hormone secretion. It is known that after pregnancy, a large number of hormones, such as estrogen, progesterone and placental prolactin, promote the growth and development of breasts and make them fuller. After delivery, with the decrease of estrogen, progesterone and placental prolactin in the body. When pituitary prolactin is no longer inhibited, the parturient will start lactation. Prolactin secreted by pituitary gland will further inhibit ovarian function. Ovary is the main "origin" of estrogen and progesterone, its function is inhibited, and the secretion of female hormones is naturally affected. Generally, after lactation, ovarian function will recover quickly. However, due to prolonged lactation, poor ovarian function, or ovarian sensitivity to prolactin, the recovery of ovarian function is slow, resulting in decreased female hormone secretion and breast atrophy. Third, some women focus on feeding their children, are afraid of getting pregnant again, are indifferent to sexual requirements, lack sexual stimulation, and may shrink their breasts. Knowing the above reasons, in order to prevent breast atrophy, we should pay attention to the following aspects during lactation: 1. Keep nipples clean during pregnancy to prevent mastitis. 2. Wear a suitable bra during lactation, not too tight to ensure normal blood circulation. 3, suitable for arranging lactation life, to ensure adequate nutrition and sleep. The best breastfeeding time is 10- 12 months. Weaning after breastfeeding for one year has no effect on the recovery of breast morphology and the nutritional intake of children. Some women don't breastfeed their children in order to keep fit, which is wrong, because breast milk is the most suitable natural food for babies to grow up. Fourth, timely implement contraceptive measures after delivery to restore normal sexual life. For those who have suffered from breast atrophy and have no organic diseases after examination, the following two remedial measures can be taken: 1. Adjusting diet can control the increase or decrease of body fat. Foods rich in nutrition and containing enough animal fat and protein can enrich the fat stored in various parts of the body, including the fat accumulated in breast tissues. The fat content in the breast increases, and the breast will naturally be fuller. 2, exercise can not make the breast itself increase, because the breast has no muscles. The purpose of exercise is to enlarge the pectoralis major muscle under the breast. Enlargement of pectoralis major will make the breasts protrude and look bigger. Here are some simple gymnastics: (1) Chest out, chest out, chest out quickly, and repeat 20-30 times. (2) Put your hands together, cross your hands forcibly on your chest, then push forward and repeat 8- 10 times. (3) The arms droop naturally and the palms are forward. Raise your arms horizontally from your side (as if you were lifting an object). When lifting horizontally, the two arms are clamped inward, and when lifting normally, the two arms are quickly hugged and straightened and lifted over the head. Repeat 10-20 times. (4) Make a fist with both hands, cross your arms in front of your face, then lift them obliquely upwards, and hold your chest while raising your arms. Repeat 10-20 times. The above four exercises are very simple and can be done at any time of the day without any equipment. Practice has proved that long-term persistence can strengthen the chest muscles and make the breasts firm and more elastic. Do not use estrogen at will, because the role of estrogen is not only to promote breast development, but also to cause changes in related organs of the whole body. Therefore, even low estrogen should be used under the guidance of a specialist.
