Thank you for your question. Spending prolonged periods sitting on the toilet after a tummy tuck, especially during the early healing stages, is unlikely to directly affect the structural integrity of your muscle repair (MR) or the overall results of your tummy tuck. However, it can contribute to discomfort, increased pressure on the abdominal area, and possible swelling. Sitting for extended periods, particularly if you’re straining due to constipation, can place additional stress on the surgical area. While this stress is unlikely to undo muscle repair or damage your results years after the procedure, it may have caused temporary discomfort or a sensation of tightness. This is especially true if you were still in the healing phase at the time. If you’re experiencing ongoing issues, such as pain, tightness, or changes in the appearance of your abdomen, it’s essential to consult with your surgeon. They can evaluate your current condition and determine if any adjustments or interventions are needed. It’s also worth discussing any ongoing constipation issues with your primary care doctor, as prolonged straining can lead to other health concerns unrelated to your surgery. In the future, maintaining a high-fiber diet, staying hydrated, and using over-the-counter remedies when needed can help prevent prolonged periods of sitting due to constipation. If you have any lingering concerns about your tummy tuck, your plastic surgeon can provide reassurance or recommend additional measures to optimize your long-term results. Sincerely, Dr. Katzen
