Thank you for the question. Your plastic surgeon will guide you when it comes to specific postoperative instructions. He/she will also be in the best position to rule out complications such as fluid accumulation (seroma). When a tummy tuck operation is performed, many of the veins and lymphatic channels that normally drain the abdominal wall are divided (severed). After the procedure, the abdominal wall swells because these channels are not functioning. Longer-term swelling after tummy tuck surgery is not uncommon; swelling may persist for many months and even up to one year after the procedure is performed. Often, patients will report that the swelling increases as their activity level increases and gets worse later on in the day. Sometimes, the use of compressive garments may be helpful to control the edema. I ask my patients to where the abdominal wall binder for one month after surgery; most patients are eager to “burn” the garment as soon as possible. Some patients however prefer to keep some form of compression garment on for a longer period of time, stating that the garment gives them a feeling of “security”. The use of compression garments such as "spanx" may be helpful thereafter. Generally, it takes many months for swelling to resolve after tummy tuck surgery and it may take up to one year (or greater) a complete skin redraping to occur. I hope this helps.
