In the 10 days after childbirth, the mother’s hormone level gradually decreases and her body is in a weakened state, which makes her susceptible to infection by bacteria and other pathogenic microorganisms and induces vaginitis and other diseases, resulting in symptoms such as odor down there. If the odor persists, further examination is needed to determine the nature of the inflammation, such as bacterial vaginitis, trichomoniasis or pseudomonal vaginal yeast disease, and treatment with drugs that have less effect on breastfeeding. If the examination does not reveal vaginitis and other diseases, it is necessary to consider whether the mother has symptoms of urinary incontinence. Because the pelvic floor function is damaged during delivery and cannot be fully recovered 10 days after delivery, functional urinary incontinence may occur, such as coughing, laughing and urine flowing out when walking, which can also lead to an odor down there. You should change your underwear and underpants diligently, dry and disinfect them after washing, and perform functional pelvic floor exercises, such as Kegel exercises, as your body allows, to help the pelvic floor muscle recover its normal physiological function, reduce urinary incontinence, and remove odor. If the odor persists down there, you should seek medical treatment promptly. If you do not pay attention to it, the inflammation may gradually worsen and spread to the cervical tissues, and then retrograde to the endometrium causing pelvic inflammation and adverse symptoms such as abdominal pain and fever. In addition to active treatment, the mother should also pay attention to maintaining a light, easily digestible diet and avoid heavy physical labor to avoid re-injury to the pelvic floor function. You should add clothes according to weather changes to reduce the incidence of colds and other diseases, and ventilate the room regularly to avoid breeding bacteria and other pathogenic microorganisms and avoid infections.
