What is a Diastasis Rectis Abdominis (DRA)? It is the excessive widening or separation between the two bellies of the rectis abdomens muscle. This can occur with pregnancy or even just excessive weight gain. Additionally, improper breathing during exertion (bearing down) and even changes in your connective tissue with trauma or inflammation can also play a role.
Up to 54% of women postpartum have a DRA and 60% of those women will also experience low back pain.
Your search to heal this may be limited on Dr. Google. It is best to hook up with a Urogynecological and/or Visceral Physical Therapist for assessment and guidance with your treatment.
