Swelling is unavoidable after surgery, and the amount of swelling can vary from one patient to another based on many factors. You will have at least two drains left in place for a couple days post surgery to reduce extra fluid accumulation and thus minimize some of the swelling. You will also be placed in a surgical binder. Both of the above will help lessen the swelling, but not completely prevent it. A tummy tuck is a major surgical procedure and, again, swelling is a normal body reaction to being cut.
