Hello! Thank you for your question! Postoperative seromas after a tummy tuck are not uncommon. They can become concerning if they become symptomatic or clinically evident. Drains and postoperative compression may help to lessen them becoming so postoperatively. While an examination is required to diagnose a seroma, your photos do suggest at least some swelling of the area, which is expected. Although I have not seen your result prior, but given the asymmetry on one side to another above the mons area, it could be a fluid collection that you have. Follow up with your surgeon for your concerns. If it is a seroma, aspiration of the area can be done as well as further postoperative instructions. Hope that this helps! Best wishes!
