Hello, Thank you for your question about the functionality of abdominal muscles after a tummy tuck (abdominoplasty). It's a common concern, especially regarding how the surgery might affect your core strength and ability to exercise. You'll be pleased to know that, yes, your abdominal muscles do continue to work after a tummy tuck. During the procedure, if muscle plication (tightening) is part of your tummy tuck, the rectus abdominis muscles (which run vertically from your lower sternum to your pubic bone) are sutured together. This process is designed to repair muscle separation and strengthen the abdominal wall. Despite this alteration, the muscles maintain their original orientation and function. When these muscles contract, such as during activities like sit-ups, they still flex in the same way they did pre-surgery. This means that after a tummy tuck, you can still perform abdominal exercises effectively. However, it’s important to allow a moderate amount of time for proper healing before engaging in strenuous abdominal exercises. Typically, a period of 4 to 6 months is recommended to ensure adequate healing and to prevent any disruption to the surgical repair. After this healing period, exercises like sit-ups and other core-strengthening activities are not only allowed but are beneficial. They can help enhance your core strength, including both the rectus abdominis and the external oblique muscles. To safely incorporate abdominal exercises post-tummy tuck, you may consider consulting online resources for specific exercises, joining a gym, or working with a physical trainer who can provide personalized guidance and ensure that you're exercising in a way that supports your surgical results. In conclusion, rest assured that your abdominal muscles remain functional after a tummy tuck. With appropriate healing time and gradually reintroduced exercise, you can continue to strengthen and tone your core muscles. Wishing you a smooth recovery and success in your fitness journey post-surgery. Sincerely, Dr. Katzen
