Thank you for your question and for sharing your photos. After a tummy tuck with muscle repair (rectus diastasis repair), the degree of tightness in the abdominal muscles can vary slightly, especially in the area below the belly button. This is because the lower abdominal region tends to have more natural laxity and may not feel as tightly compressed as the upper abdomen. Being able to fit a finger between the abdominal muscles when relaxed is not uncommon, particularly below the belly button. When you tense your muscles and they come together, this indicates that the repair is still holding, as the rectus muscles are functioning properly. However, if you notice a persistent gap larger than one finger width, a bulge, or symptoms such as discomfort or weakness, it could suggest a mild recurrence of separation or insufficient repair. This is best evaluated in person by your plastic surgeon, who can assess whether the muscle repair is intact and functioning as expected. If the repair is holding but you are concerned about the appearance or feel of your lower abdomen, additional strengthening exercises, physical therapy, or a revision procedure might be options to explore. If the area feels firm and shows no bulging or asymmetry, there is likely no immediate cause for concern. However, I encourage you to discuss this with your surgeon for clarity and reassurance. Sincerely, Dr. Katzen
