Hello Charona_91, Thank you for your question regarding the jiggling sensation in your stomach after your tummy tuck surgery. At 1 year and 6 months post-op, your body should have largely healed from the surgery. The skin and muscle typically reattach well during the healing process. However, a few factors might contribute to the sensation you're experiencing. Scar tissue formation is part of the healing process, and sometimes scar tissue can form unevenly, which might create areas that feel different or less stable. Additionally, fat can redistribute or remain in certain areas, contributing to the jiggling sensation you feel, especially when lying down. If muscle repair was part of your tummy tuck, it’s possible that the muscle healing is not as tight as desired, which might contribute to some movement under the skin. Lastly, some degree of skin laxity might remain, contributing to the jiggly feeling. To address these concerns, I recommend an ultrasound examination to get a clearer picture of what is happening under the skin, whether it's fat, fluid, or something else. Although a seroma was ruled out initially, it might be beneficial to get another ultrasound examination. Revisiting your plastic surgeon or seeking a second opinion is also advisable. They can physically assess the area and may suggest additional tests or imaging to diagnose the issue accurately. Engaging in physical therapy, particularly exercises focused on core strengthening, might help improve muscle tone and reduce the jiggling sensation. Wearing a compression garment might also help by providing additional support and reducing the jiggly feeling. In some cases, a minor surgical revision might be required to address any underlying issues that did not heal as expected. It’s important to follow up with your plastic surgeon to understand the exact cause of the jiggling sensation. Given your description, it seems unlikely that the skin and muscle have not reattached properly, but a detailed examination will provide clarity. Good luck, and I hope I’ve answered your question regarding the jiggling sensation in your stomach post-tummy tuck. Sincerely, J. Timothy Katzen, MD, FASMBS, FICS Plastic Surgeon
