After giving birth, the uterus and pelvic organs have not yet fully recovered, so the stomach will still be slightly bulging, which is a normal phenomenon, and usually will gradually return to flatness in about 6-7 weeks. The enlarged uterus is basically located at the level of the flat umbilicus after delivery, so the belly of a woman after giving birth is still in a bulging state. After delivery, the uterus recovers at a rate of about 1-2 cm per day, so it will return to its non-pregnant state in about a month and a half. If the abdomen does not return to the pre-pregnancy state after 6-7 weeks after delivery, it may be due to obesity or separation of the rectus abdominis muscle, and even some mothers’ abdomen may never return to the pre-pregnancy state. About 1 week after giving birth, you can start to do rehabilitation exercises, such as proper sit-ups, yoga and other exercises to exercise the abdominal muscles, in order to promote the abdomen to recover as soon as possible.
