Drinking brown sugar water dew again, the main reason may be a shorter postpartum time, poor uterine contraction or uterine cavity is caused by residual, and drink brown sugar water will not have too much to do. 1. Shorter postpartum period: generally, bad dew will not completely disappear until about 42 days after delivery. So within 42 days there will occasionally be some bad dew, but the amount of bleeding does not exceed the usual amount of menstruation. This is normal and does not require treatment. 2. Poor uterine contraction: the uterus should gradually contract back to normal size after delivery, if the uterine contraction function is weakened, there will be repeated small amount of bad dew or bleeding is too much, you need medication such as uterotonin. 3. Uterine cavity with residual: after delivery of the uterine cavity with residual fetal membranes or blood sludge, then there will also be frequent bad dew. You need to check the ultrasound again, according to the ultrasound results to observe whether the uterus is cleansed or medication. The presence of postnatal discharge has little to do with drinking brown sugar water. If you find abnormal postnatal discharge, consult the doctor for ultrasound examination to determine the cause of the disease and then treat it, so as to avoid delaying the disease.
