Postpartum vaginal wall bulge usually refers to the bulging of the anterior or posterior vaginal wall after a normal delivery. If the bulge is not severe, it usually recovers slowly about 42 days after delivery, while severe bulge may require pelvic floor rehabilitation to recover. When a woman gives birth in normal labor, the fetus will be delivered from the vagina, so it may lead to overexpansion of the vaginal wall muscles and cause vaginal laxity, which often leads to bulging of the anterior and posterior vaginal walls and uterine prolapse, so it is recommended to review the pelvic floor muscle strength 42 days after delivery to see if there is laxity of the pelvic floor muscles and then consider whether pelvic floor repair is needed based on the results of the examination. If the anterior vaginal wall bulge has recovered, no treatment is needed. If the vaginal wall bulge has not recovered, pelvic floor rehabilitation can be done in the hospital gynecology department, usually twice a week for a month. The pelvic floor muscle can be contracted by doing anal contraction exercises to promote its contraction recovery as soon as possible. It is also recommended to strengthen the recuperation after delivery, avoid overexertion, especially to avoid increased abdominal pressure and weight-bearing exercises.
