There are more reasons for postpartum vaginal fart, mainly including postpartum vaginal laxity and vaginitis, which should be treated for the cause after the cause is clear. Common causes and treatment 1, postpartum vaginal laxity or vaginal lateral incision: When the whole body of the fetus is delivered from the vagina, it will exert some pressure on the pelvis, muscles and ligaments of the pregnant woman, and vaginal laxity may occur. A lateral vaginal incision may also be performed in women who have difficulty delivering vaginally. This is a normal physiological phenomenon and patients need not worry too much. 2. Vaginitis: When the natural defense function of the vagina is damaged, pathogens can easily invade and cause vaginal inflammation, resulting in dysbiosis of the vaginal flora, bacterial multiplication, increased vaginal exhaust and symptoms of postpartum vaginal farting. It can be treated with metronidazole tablets and nifurtimox suppositories as prescribed by the doctor, which are administered vaginally and do not affect breastfeeding. It is recommended that mothers should pay attention to personal hygiene, change underwear regularly and keep the perineum dry and clean. It is recommended that mothers should lie down on the bed or sit on the bed to relax their bodies, tighten the anus, strengthen the functional exercise of pelvic floor muscles, restore the vaginal muscle groups and promote vaginal contraction.
