Breastfeeding is not only harmless to the mother, but also promotes uterine contraction, weight loss, prevention of breast diseases and many other benefits that need to be analyzed specifically. 1. Promote uterine contraction: when breastfeeding, it will stimulate the nipple, and this stimulation will reflexively cause pregnant women’s uterus to contract, promoting the uterus to return to the pre-pregnancy level. 2. Weight loss: when breastfeeding, women’s metabolism will be faster, which can increase the consumption of energy, and promote maternal weight back to pre-pregnancy levels. 3. Preventing breast diseases: Breastfeeding is good for the smoothness of the milk ducts, which can improve the blood circulation of the breasts and prevent breast tumors and other diseases. It is recommended that women actively breastfeeding is beneficial to both pregnant women and babies. If there are uncomfortable symptoms after breastfeeding, it is recommended to go to the hospital in time and follow the doctor’s instructions to deal with the treatment.
