Diastasis rectus abdominis refers to a gap of more than 2cm between the two sides of the rectus abdominis or 'six pack' muscle. It is visualised or a coning or a doming between the muscle bellies. Often this gap will naturally reduce after you have had your baby but if you are worried you may need to seek help from your pelvic health physiotherapist. Please see our Spotlight On video for further information about diastasis.
