2. The main function of the abdominal belt is not to lose weight. Maternal doctors usually let them wear the abdominal belt after giving birth. In fact, the main purpose is not to lose weight, but to prevent internal organs from sagging. Because postpartum women are weak, the elasticity of ligaments in the body can not be recovered immediately, and it is easy for internal organs to droop. Therefore, it is best for postpartum mothers to wear appropriate abdomen straps to help the body support internal organs and prevent internal organs from sagging. In addition, it is suggested that the parturient after caesarean section wear abdominal band to stop bleeding and promote wound healing.
