Swelling After Body Contouring Surgery: Why It Happens

Mon 26th Oct 2026

Feeling swollen or bloated after Body Contouring surgery is expected and usually forms part of the normal healing process. While swelling and bloating can be uncomfortable, they generally improve as your body recovers.

In this article, we break down what happens during recovery so you can understand the process and feel a little more at ease.

In summary

• Swelling is a normal part of healing, caused by an inflammatory response, and usually improves as you recover.
• Surgery temporarily affects the tissues, blood vessels and lymphatic system, contributing to swelling.
• Most swelling typically passes within a few weeks, but some residual swelling may last longer.
• Drugs and medications used during surgery, combined with physical inactivity, can cause bloating and constipation. Movicol or other laxatives can help.
• Post-surgical swelling is different from a seroma, which may require treatment.

Swelling At the Surgical Site

Swelling is a part of your body’s natural inflammatory response to surgery. During Body Contouring Surgery, tissues are cut and moved, and this temporary disruption injures the soft tissues and blood vessels, prompting the body to send extra fluids, blood cells and nutrients to the area to heal.

This extra fluid is a sign that your body is working hard to heal itself.

Surgery can also disrupt the lymphatic vessels that normally help drain excess fluid from the tissues. This can contribute to fluid buildup while the lymphatic system recovers.

Swelling is often most noticeable during the first few days after surgery and may continue to fluctuate during the first week. From there, it should gradually begin to settle, although some swelling can remain for several weeks or months.

Other Reasons for Post-Surgical Swelling

Beyond healing, other areas and functions of your body can also be affected.

Intravenous fluid: During surgery and your hospital stay, you may receive intravenous (IV) fluids. These can temporarily contribute to fluid retention and swelling, especially if the procedure is long and requires a large volume of IV fluids.

Slowed gastrointestinal tract: Anaesthesia, some pain medications, and reduced activity can temporarily slow the digestive system. Consequently, many patients experience post-operative constipation, which can lead to more bloating and discomfort.

Decreased physical activity: Your activity levels have been greatly reduced due to your surgery, which can lead to fluid retention and worsen swelling and bloating. You may also gain a small amount of weight over time because you’re not burning calories the way you normally do. However, as the weeks pass, you’ll slowly be able to return to more physical activity and exercise.

How to Address Post-Surgical Bloating and Swelling

Fortunately, you can do things to help alleviate some bloating and swelling during recovery.

• Wear your compression garment: It will provide support and compression and may help reduce post-operative swelling and inflammation. Dr Dona typically advises his patients to wear the garment at all times except when bathing.
• Take Movicol (or similar laxatives): After your procedure, you’ll usually be given Movicol to help prevent constipation. If desired, you can continue taking this for the first few days after you return home from hospital.
• Mobilise regularly: While we want you to rest and recuperate, it’s important you do some mobility exercises. In the early days, particularly if you’ve had a major operation, this may be as simple as moving your ankles and wrists. Next, you’ll be asked to get yourself out of bed and take a few gentle steps. As you recover, try to get up regularly to move gently around the hospital or house. This will help encourage circulation, support lymphatic drainage and reduce the risk of blood clots.
• Stay hydrated: Drink plenty of fluids to stay well hydrated, which supports healing, reduces the risk of water retention and helps address constipation.
• Keep your surgical site elevated: For example, if you’ve had a , Thigh Lift, or Thigh Lift (Lipectomy), keep your feet elevated while you’re in bed or sitting, or elevate the head of your bed to help prevent unnecessary swelling.
• Lymphatic massage: If Dr Dona has cleared you, you can begin light lymphatic massage, which can help reduce swelling and increase circulation.
• Take anti-inflammatory medication: Dr Dona may prescribe anti-inflammatory medication to help manage inflammation and discomfort.

Post-Surgical Swelling vs A Seroma

The body’s inflammatory response causes post-surgical swelling, or oedema, a form of interstitial swelling. The body sends blood- and protein-rich fluid to the area to begin repair. Fluids build up within and between cells in the interstitial space (the tissue layers beneath the skin, fat, and muscle).

This is a normal part of the healing process, and all patients experience it, although the amount of swelling varies from person to person.

However, a small percentage of individuals develop a seroma, which differs from interstitial swelling.

While interstitial swelling involves excess fluid in the spaces within the tissues, a seroma is a pocket of clear serous fluid that forms in the space created by surgery. It may feel like a soft, squishy bump near your wound, and the skin on top feels tight or stretched. It may also be mildly uncomfortable or sore.

Surgery creates empty spaces under the skin where tissue was cut or removed. Your body sends out serous fluid (a clear fluid made from blood plasma and lymph) to help fill the space. Sometimes this fluid pools in a pocket instead of being absorbed right away.

To treat a seroma, Dr Dona typically aspirates it using a sterile needle and syringe to drain the fluid. Some small seromas may resolve without treatment, so the appropriate approach depends on the size and symptoms.

When To Contact The Clinic

Some swelling and bloating are expected after Body Contouring surgery. However, contact the surgical team if your swelling suddenly increases, becomes severe or is accompanied by increasing pain, redness, warmth, fever, wound problems or other symptoms that concern you. Dr Dona can assess whether what you’re experiencing is part of the normal recovery process or requires further treatment.
