Almost two months after childbirth, malodex keeps recurring, which is often clinically caused by the following reasons: 1. Infection during the puerperium, due to pathogenic bacterial infections that cause inflammatory reactions in the endometrium and irregular shedding of the endometrium, resulting in recurring malodex. 2. Residues in the uterus, such as placental residues or fetal membrane residues, can cause unclean malodex. 3. 4. The uterus does not recover properly due to poor rest, so it is advisable to rest and have family members help with the newborn after delivery, which will help the body recover as soon as possible.
