When it comes to post-tummy tuck care, the size of gauze pads you need will depend on the size of your incision and the amount of drainage. Generally, a 4x4 inch gauze pad should be sufficient for most patients. However, if you have a larger incision or are experiencing heavier drainage, you may need to use larger pads. It's important to change your gauze pads regularly to prevent infection and promote healing. Follow your surgeon's instructions and guidance for post-operative care, as they can provide specific recommendations tailored to your individual needs. Thank you for your question, and best of luck with your recovery. Sincerely, Dr. Katzen.
