Many postpartum mothers who have given birth by cesarean section encounter a worry: the cesarean section wound is enlarged. Not only is it painful and itchy, but it also affects the aesthetics and quality of life. This hyperplasia is mainly due to the lack of collagen and elastic fiber tissue production, which is not enough to compensate for the wound, and the formation of skin discontinuity. Because postpartum mothers have to breastfeed, they should treat scar growth in stages. I. Within the breastfeeding period 1.Application of scar growth softening ointment: In the early stage of scar growth formation, you can use some ointment for scar growth during the breastfeeding period under the guidance of your doctor to relieve the redness and swelling of scar growth as well as to stop itching. 2.Laser removal. Fractional laser can be used to inhibit the early growths from continuing to deteriorate. After treatment, you should pay attention to moisturizing the affected area and follow medical advice for care if there is a break in the area. Also pay attention to diet and avoid spicy and stimulating food. Second, the end of breastfeeding period 1.Injection of scar softening injection: You can try to inject scar softening injection after the end of breastfeeding period, so that the raised scars can be restored to flatness first, but the width of the scars will not change. 2.Surgical excision. For patients with higher requirements, as well as those with more serious hyperplasia and obvious symptoms, surgical excision of the hyperplastic scars is recommended at one time. The lesion is removed at once by means of local anesthesia, with super-reduced fine sutures, using layered sutures, and the recovery is a very thin fine line, which not only greatly restores the appearance and gives the mother back her confidence. It also relieves the pain and itching symptoms, and is the most commonly used means of treating cesarean scar growth in clinical practice.
