What Is Post Procedural Swelling?
Post procedural swelling, also called surgical edema, occurs when fluid builds up in the tissues after surgery[1][2]. This is a natural response of the body to heal and can show up in various forms. The fluid that accumulates is mostly water, along with plasma and lymphatic fluid[2].
Swelling is your body’s natural response to injury or surgery[1][5]. It occurs as fluid accumulates in the tissues surrounding the surgical site. This is part of the healing process, but excessive swelling can hinder recovery and cause discomfort[1].
The volume of fat or tissue removed during a surgical procedure is temporarily replaced by swelling. In some cases, the operated areas may appear more voluminous than before the procedure, but there is no cause for concern[2].
What Causes Post Procedural Swelling?
The primary reason for swelling after surgery is the trauma to the treated tissues[3][10]. Swelling, and the associated bruising, is never symmetric. One side will tend to swell or bruise more than another, and that is a normal phenomenon[3].
General anesthesia tends to cause the blood vessels to dilate, and the blood vessels can leak fluid into the surrounding tissues. To be safe, most anesthesiologists administer more fluid than is needed, which compounds the swelling temporarily[3].
Swelling can arise from various factors, including surgical trauma, inflammatory processes, and fluid balance issues[2]. Whenever a surgeon makes cuts, the body responds with inflammation and fluid buildup, leading to surgical swelling. Additionally, certain patients with conditions like obesity or vascular issues are at higher risk for excessive swelling[2].
Limited movement during recovery can also contribute to swelling. Because many patients are largely immobile after surgery, they can experience swelling as a side effect[8][16]. Gravity helps fluids move freely throughout your body, so prolonged immobility and a sedentary lifestyle may lead to swelling[8].
Common Signs of Swelling
Common signs of post-surgery swelling include[1][5]:
- Increased size and tightness: The operated area appears larger and feels tight
- Pain and discomfort: Swelling often comes with increased pain
- Stiffness: Movement can be restricted due to the swollen tissues
- Warmth and redness: The area may feel warm and appear red
How Long Does Swelling Last?
The worst of the swelling should occur the first few days after surgery[3][10]. The peak of swelling is typically observed between day 3 and day 10 after the procedure[12].
About a week after surgery, it should start to subside. Two weeks after surgery, 75 percent of the swelling should disappear. By six weeks after surgery, nearly 90 percent of the swelling should have dissipated, with any remaining swelling subsiding over the next few months[3][10].
The duration for the disappearance of post-operative swelling varies significantly depending on the patient[12]. It can take a minimum of 6 weeks, on average 3 to 6 months, and up to a year in some cases[12].
Sometimes, swelling appears asymmetrically between one limb and the other. There is no cause for concern; in some patients, a slowdown in the lymphatic system on either the left or right side can explain this asymmetry[12].
How to Manage and Reduce Swelling
Managing post-surgery swelling can help ensure your recovery while minimizing your discomfort. Although you cannot completely avoid swelling, you may benefit from the following strategies[1][3][5]:
Elevation
Keeping the affected area elevated high in the air, greater than 60 degrees of elevation, has been shown to significantly reduce swelling by encouraging fluid to drain away from the surgical site[5][7][18]. Raising the swollen area aids the body in reducing swelling and inflammation by moving fluid away from that area. This is most easily accomplished by laying on your back with the area resting on top of some pillows. This should be continued for at least three days after your surgery[7].
If you had facial plastic surgery, make sure to keep your head elevated, even while sleeping. Prop yourself up on some large pillows to make sure you stay elevated and have gravity help with decreasing the facial swelling[3][10].
Cold Therapy
Applying ice packs or cold compresses to the swollen area can help numb pain and reduce inflammation[5][14]. Use cold therapy in 15-20 minute intervals, ensuring a cloth barrier between the ice and your skin to prevent frostbite[5]. Cooling the affected area can help reduce inflammation and swelling during the healing process. As with elevating the area, this is most beneficial in the first few days after your surgery[7][18].
Compression
Using compression garments or bandages can help limit swelling[5]. These apply consistent pressure to the area, preventing fluid build-up. Compression garments put slight pressure on the treated tissues as they heal. Often this helps minimize swelling during body surgery such as breast augmentation, tummy tucks, liposuction and arm lifts[3][10].
Compression should be applied at the end of the procedure and worn during the first weeks or months after the procedure. It will gradually be reduced depending on the rate of swelling reduction[12].
Hydration and Nutrition
Staying hydrated by drinking plenty of water supports healing[3][14]. Eating a low-sodium, nutrient-rich diet with fresh fruits and vegetables, whole grains, lean proteins, and low-fat dairy can help reduce swelling[20]. Cutting down on sodium is particularly important[3][14].
Rest and Activity
Getting lots of rest and avoiding strenuous exercise during the first two to three weeks after surgery is important, as exercise can actually increase swelling[14]. However, sitting still after your surgery will promote stiffness and swelling and can impede the healing process. While it’s essential that you take care with the surgical area, the rest of your body should still be kept in motion[7][18].
Heat Avoidance
Avoiding sun exposure as much as possible and making sure that you stay as cool as possible is important. Heat can increase and prolong swelling[14].
Additional Therapies
Gentle massage or external treatments such as lymphatic drainage massage by a specially trained massage therapist may be a good option to help reduce swelling[3][10]. Lymphatic drainage is strongly recommended after surgery. Starting 7 to 10 days after the surgery, it helps activate the elimination of swelling. It is recommended to undergo two drainage sessions per week for a minimum duration of 5 weeks[12][13].
Herbal supplements such as Arnica Montana and Bromelain are thought to decrease swelling, bruising and pain right after surgery[3][10][14].
Medication Considerations
Do not take medications and supplements that thin the blood, such as aspirin, warfarin, vitamin E, and ibuprofen[14]. Quitting smoking, at least for the first few weeks after surgery, is important as smoking interferes with proper healing and can significantly extend your healing period[14].
Following Medical Instructions
In general, it is extremely important that you follow your doctor’s post-surgical instructions to the letter to ensure that your healing period is as comfortable and brief as possible[3][14]. Many of these instructions are intended to minimize swelling and other unwanted side effects[3]. As a patient, you will play an essential role in your own recovery[14].
When Swelling Indicates a Problem
While swelling is normal, you must watch your healing carefully. If the swelling does not lessen or worsens, this may show a complication[2]. Fluid collections can cause pain and anxiety for the patient, leading to increased healthcare visits and cost of care. Local wound problems can occur, such as wound opening and tissue death, requiring further surgical care[4].
Swelling is also associated with an increased risk of wound infection and possible abscess formation[4]. Left untreated, swelling can eventually lead to stiffness, difficulty walking, skin ulcers, scarring, and poor circulation[8][16].
If something feels wrong, do not wait. Talk to your surgeon for help[20]. If you’re experiencing swelling after surgery, make sure you talk to your doctor about what you can do to reduce swelling[8][16].
