It is normal for the labia to become larger after pregnancy. After pregnancy, due to fetal pressure, the child is getting down after pelvic, and the fetal baby is big enough to squeeze the bladder, which makes the blood circulation in the lower body obstructed and easy to be infected, which is what causes the labia to swell in late pregnancy. But pregnant mothers don’t need to worry, as long as they pay attention to more activities. Lying on your back is good for recovery, doing proper exercises and applying anti-inflammatory ointment topically will heal soon and you will recover after giving birth. It is recommended that pregnant women can wear breathable underwear. If you often wear non-breathable underwear, it will easily lead to excessive moisture in the vulva, thus resulting in vulvar inflammation and redness. Secondly, you should avoid stimulation. During pregnancy, you should try to avoid standing and sitting for a long time, otherwise it may cause symptoms such as vulvar swelling. In addition, the vulva should be washed frequently. There are many reasons for an overly large vulva, such as daily pressure, etc. We need to do a good job of hygiene and timely washing so that recovery will be faster.
