After surgery, the abdominal area is in a delicate state as the body begins the healing process. If there is a sudden increase in abdominal pressure related to anything from coughing, sneezing, vomiting due to nausea, or getting a case of the hiccups, the compression garment provides important protection in terms of stabilizing the area. It is also helpful with the edema (swelling) that always follows a surgery. It takes roughly three to six months for most of the swelling to go away so the garments are crucial during the first month after a procedure.
(Ironically, we don’t have any studies to back up the importance of compression garments after abdominal surgery because no patient would want to attempt not wearing them after a tummy tuck surgery. They are just good medical common sense.)
