How Long Does It Take for the Sutures to Heal in the Stomach Muscle in a Tummy Tuck?

Great question. Usually from 3 to 8 weeks for full healing to occur. But the larger the separation between the recti muscles the longer to get a "solid" repair.

The best way to determine this is with a CT scan or Ultrasonic imaging. However, it typcially can be evaluated with a simple head lifting maneuver while laying flat on your back and feeling the edges of the muscle. It typically takes 3 months after surgery to determine if the repair is "solid". Performing core strengthening exercises (Pilates style) help to approximate and keep the muscles in place after the repair

The muscles that run from the ribs to the pubic bone do not cross the midline so they frequently get pushed apart with pregnancy. No number of situps can pullthen back into alignment, so that is why they are frequently "repaired" with stiches to pull them back into position and strengthen the abdominal wall. When this is done, it is similar to a hernia repair, which we know from experience and studies in general surgery takes about 6 weeks for full healing. It would be very unusual for one of the stiches to pull loose unless you were really straining the muscles, and you would probably have felt a pop.
