Whether the separation of the rectus abdominis muscle needs to be repaired depends on the specific recovery situation. The separation of the rectus abdominis muscle is caused by the enlarged uterus during pregnancy, and most of them can recover on their own after delivery, if the rectus abdominis muscle has not been combined for a long time after delivery, repair is necessary, and in serious cases, surgery can be performed. Separation of the rectus abdominis muscle is mostly seen in postpartum women. The reason is that as the uterus gradually increases in size during pregnancy, the pressure on the abdominal wall increases, the abdominal wall gradually becomes weaker, the rectus abdominis muscle on both sides of the white line loosens, and the distance between the rectus abdominis muscles on both sides becomes larger, which leads to the separation of the rectus abdominis muscle. Clinically, when the distance between the two sides of the rectus abdominis muscle is greater than 3 cm, it is diagnosed as a separation of the rectus abdominis muscle. Most mothers can recover on their own after delivery, but in some cases, the separation of the rectus abdominis muscle has not improved due to poor nutrition and improper exercise, and must be repaired. Some patients even develop abdominal wall hernias, which require surgical treatment to reunite the separated rectus abdominis muscles on both sides with sutures. Separation of the rectus abdominis should be taken seriously and rehabilitated if necessary. If the rectus abdominis muscle is separated for a long time and is not treated in time, the gap between the two sides of the rectus abdominis muscle will gradually be filled with fatty tissue, which will not only affect the body shape but may also lead to a variety of complications.
