The causes of lobular hyperplasia are not only the lack of a harmonious sex life, long-term sexual repression, lack of sexual pleasure, but also related to the age of first birth over 30 years, never had children, unmarried at an advanced age, not breastfeeding after childbirth, many miscarriages, low sexual function and marital disharmony. According to Chinese medicine, lobular hyperplasia of the breast is caused by liver and qi stagnation, phlegm and qi stagnation, and is related to unhappy emotions and depression. If the couple has a happy relationship between the sexes, including a coordinated and harmonious sex life, you can keep your mood relaxed, liver qi flowing freely, the qi and blood in the veins and veins are harmonized and smooth, and the lobules of the breast are not easily enlarged. Therefore, it can be said that a harmonious sex life is an important positive measure to prevent the occurrence of lobular hyperplasia of the breast. In order to prevent lobular hyperplasia, in addition to advocating marriage at the right time (not more than 28 years old), childbirth should not be too late (not more than 30 years old); after childbirth, if there are no special circumstances, must be their own breastfeeding; good contraceptive work, to eliminate multiple abortions, hyperplasia of the breast gland is not easy to atrophy and promote the cause of breast hyperplasia; very important point is that women should pay attention to lead a good sex life. Normal, harmonious, balanced and regular sex life can not only bring physical and mental pleasure and entertainment to yourself, enhance the relationship between husband and wife, but also, help reduce the occurrence of mastopathy and breast cancer. This is because the breast itself is also a sexual organ, and during sex the breast can also occur cyclical changes. For example, during the sexual excitement period, the breast veins are engorged with blood and the breasts are swollen and enlarged; during the sexual duration, the areola is engorged with blood and the nipples are erect; during the orgasm, the above changes reach their peak; after the orgasm, the areola is engorged with blood and the breast enlargement takes 15-30 minutes to return to normal. Women who have been sexually repressed for a long time, or who have not had sex, are not the same as not being sexually aroused. Women who think they are sexually indifferent may lack a normal sex life due to a lack of corresponding sexual stimulation and a long-term state of sexual inhibition. The sexual response cycle, like childbirth and breastfeeding, is a regulation of mammary gland function. Once the lack of regulation of this physiological process, the endocrine system is easily dysregulated and prone to continuous congestion and swelling of the breast, leading to breast hyperplasia or breast cancer.
