Swelling after a full tummy tuck procedure with muscle tightening can last up to 6 to 8 weeks and is dependent on fluid intake (drinking a lot of water), Salt intake (high sodium causes fluid retention), Protein intake (low protein causes more swelling) and hemoglobin level (anemia causes more swelling. A fluid collection under the skin may also occur if the drains were removed too soon (Seroma) which acts like a fluid wave under the skin. Your board certified plastic surgeon should be able to help you.
Swelling that occurs with a tummy tuck can last at least 6 to 8 weeks but the final result due to decrease swelling will occur in three months.
