The term “great aunt” refers to menstruation. The brownish color of menstrual blood after Lipo knife surgery may be normal postoperative bleeding from the wound, or it may be caused by secondary infection or irregular menstruation. It is recommended to consult the doctor in time to find out the cause and treat it under the doctor’s guidance. 1. Normal bleeding: After Lipo surgery, there may be a little blood seepage from the wound. If the blood does not flow out in time and oxidization occurs, and then it is slowly discharged, brown blood may appear, which is mistaken for the arrival of menstruation. 2. Secondary infection: After Lipo surgery, the color of menstrual blood is brown, and it may be caused by secondary infection, in addition to the brown color of the blood, the patient may also have chills, fever and other infections. 3. Irregular menstruation: The brown color of menstrual blood after Liparoscopic surgery may be caused by the patient’s recent mental stress and anxiety, which may disrupt the endocrine system and lead to irregular menstruation. If the color of menstrual blood is brown and the amount is large after the Liposuction, or if the symptoms persist and do not get better, you should go to the hospital in time for treatment.
