Sally Hi….I am just over 2 weeks post op tummy tuck. My internal muscles did have some diastis and needed to be sutured back. My main concern is the longevity of the sutures. My doctor says they last a lifetime. I am an active 45 yr. old runner. I also use some weights and definitely work on my core. I am so concerned that the core workouts and abs exercises will bust my sutures. I would love to hear of some success stories to maybe ease my concerns. Thank you!
