The causes of malignant discharge turning into blood again 25 days after delivery include poor uterine recovery, residual uterine tissues, uterine cavity infection, and cervical opening lacerations. When there is a lot of bleeding, you need to go to the hospital as soon as possible to clarify the cause and treat the cause. Common causes and treatment methods 1. Poor uterine recovery: poor contraction of the uterus after delivery, poor contraction of the uterus, residual fluid and blood in the uterus from the vagina, which may lead to 25 days of malodorous dew turning into blood again. Usually choose contraction to promote uterine contraction, while insisting on breastfeeding to help the uterus to recover; 2, residual uterine tissue: placenta and fetal membrane residue, there will be bleeding, abdominal pain and other symptoms. It is recommended to perform curettage. In case of cesarean delivery, it is safer to perform curettage under ultrasound positioning and give drugs to promote uterine contraction after surgery, such as uterine contraction; 3. Uterine cavity infection: If there is infection in the uterine cavity and inflammation stimulates the endometrium, there may be 25 days of malodex turning into blood again, accompanied by abdominal pain, fever and other symptoms. You can follow the doctor to use antibiotics available for maternity to control the infection, while paying attention to rest, changing underwear regularly and drinking more water; 4. Poor healing of cesarean incision: If you had a cesarean delivery, poor healing or splitting of the incision can cause bleeding and lead to redness of the malodex. It is recommended to visit the hospital in time to stop the bleeding; 5. Cervical opening lacerations: If there are lacerations at the cervical opening during delivery and they have not fully recovered, there will also be 25 days of malodex turning into blood again. If there is a lot of bleeding, you need to go to the hospital to check the recovery of the wound, and if necessary, suture it. Anti-infection treatment can be given for combined infections; 6. Maternal systemic diseases: the mother suffers from systemic diseases such as iron deficiency anemia, and at the same time, excessive blood loss and excessive fatigue during delivery cause poor contraction of the uterus, and after the uterine blood is discharged, the malodorous dew may turn into blood again in 26 days. You can apply contractin to improve the symptoms and actively treat the original disease. Pay attention to hygiene during the postpartum period, change your underwear regularly, observe the color, nature and amount of the dew, and seek medical treatment for any abnormalities.
