Separation of the Abdominal Muscles
It is highly recommended that you check your rectus muscles along the central seam, directly down the center of your abdominal muscle, for a separation, known as a diastasis recti. This condition can occur for many reasons, pregnancy being one of them. However, you can work on this diastatsis recti during pregnancy to help lessen its effects and decrease the width.
Postpartum support belts can be very beneficial. This is especially true if you're having trouble remembering to hold in your abdominal muscles as you work out or go about your day. If you gave birth to multiples or suffered a severe overdistention for a variety of reasons, it might be even more helpful.
