Swelling (edema), bruising and pain often occur at the treated area after liposuction, especially in the first weeks after surgery[1]. For seroma, a meta-analysis of 39 studies including 29,368 liposuction patients found a prevalence of 0.65%[2]. Seroma was reported more often in some settings, including in 3.3% of 6,964 patients in a systematic review of high-definition liposuction[3][2].
Local swelling, bruising and pain at the site where fat was removed are often seen after liposuction, especially in the first weeks after surgery[1].
In a prospective study of 46 patients who had liposuction combined with a helium-based plasma radiofrequency device, postoperative edema was recorded in 22 cases (47.8%) and bruising (ecchymosis) in 11 cases (23.9%)[4]. In the same study, mild seroma occurred in three cases (6.5%)[4].
Generalized edema was rare in a meta-analysis of 29,368 liposuction patients, with a prevalence of 0.041%[2].
In a series of 870 liposuction cases, 65% of which had an aspirate volume greater than five litres, serous discharge from the access sites and blood-tinged fluid accumulation requiring drainage occurred in less than 10% of cases[5].
Ask your surgeon how much swelling, bruising and fluid leakage to expect after your own procedure.
Research describes swelling, bruising and pain as especially common in the first weeks after liposuction, and one study still measured differences in swelling at 21 days[1].
In a pilot study of 52 patients who had liposuction of both flanks followed by breast fat grafting, swelling, bruising and pain were measured at seven, 14 and 21 days after surgery[1]. Swelling in the taped area of that study differed significantly at 14 and 21 days after surgery[1].
In a study of 50 men who had very large-volume liposuction, patients were followed up every other day for three weeks to detect seroma[6].
In a systematic review of submental liposuction, which contours the lower face and the front of the neck, the mean time to onset of adverse events was 1.7 months, with a median follow-up of 10 months[7].
Ask your surgeon when your swelling is likely to settle and how often you will be seen during recovery.
Seroma is a recognized complication of liposuction, listed among the common complications alongside infection, bleeding, haematoma and lymphoedema[8].
In a study of very large-volume liposuction, seromas were graded by their volume as mild, moderate or severe[6].
Seromas matter because, if they are not detected promptly, they can impair the results of liposuction[6]. The same authors noted that seroma after liposuction causes much distress to the surgeon and the patient and can affect overall satisfaction[6].
A radiology review presented computed tomography and ultrasonography findings for a wide spectrum of postoperative complications associated with liposuction[8].
Ask your surgeon how a seroma would be checked for and treated if one develops.
Seroma is uncommon after liposuction overall, with a pooled prevalence of 0.65% (95% CI, 0.33% to 1.24%) in a meta-analysis of 29,368 patients[2].
In that meta-analysis, the most common complication was contour deformity, at 2.35%, while hematoma occurred in 0.27% and infection in 0.020%[2].
In a systematic review of high-definition liposuction, an advanced technique designed to create a defined anatomical profile while promoting skin retraction, seroma affected 231 of 6,964 patients (3.3%)[3]. Seroma was the second most frequently reported complication in that review, after transient hyperpigmentation (3.8%)[3].
In large-volume liposuction, the use of multiple energy-based devices to increase skin and soft tissue contraction has been linked with a possible heightened risk of seroma formation, at 2.27%[9].
In a systematic review of 2,085 submental liposuction cases, the adverse event rate was 12.9% per procedure, and seromas accounted for 57 of the 270 reported adverse events (21.1%)[7].
In a systematic review of liposuction-assisted gynecomastia surgery, the two good-quality studies, both using laser-assisted liposuction, reported minor seroma in two patients[10].
Seroma is described as a common complication after liposuction, especially in mega-sessions of more than five litres[6].
Early ultrasonic liposuction instruments had a number of drawbacks, including seromas and tissue burns[11].
Studies in abdominoplasty patients have reached different conclusions about whether adding liposuction raises the risk of seroma[12][13][14][15].
In a retrospective cohort of 200 abdominoplasty patients, seroma occurred in 31.2% of those who also had flank liposuction, compared with 16.0% of those who had abdominoplasty alone[12]. In that study, increasing body mass index and flank liposuction were independent predictors of seroma in abdominoplasty patients[12].
In a retrospective review of 118 abdominoplasty patients, seroma rates were comparable with flank liposuction (29%) and without it (38%)[13]. Overweight or obese patients in that abdominoplasty study developed seromas more often than patients of normal weight, at 38% compared with 19%[13].
In 146 patients who had type 4 abdominoplasty, seroma occurred in 26% of patients without progressive tension sutures and in 4% of those with them[14]. The authors concluded that progressive tension sutures significantly reduce seroma in abdominoplasty and that simultaneous liposuction does not contribute to this complication[14].
In a retrospective cohort of 619 abdominoplasty patients, patients who also had liposuction were not at a higher risk of seroma, whether they had drain-based abdominoplasty or drainless abdominoplasty with progressive tension sutures[15].
Ask your surgeon whether your weight, the volume to be removed, the technique or any combined procedure could affect your own seroma risk.
In one prospective study of very large-volume liposuction, seroma developed in 4 of 25 men who had drainage procedures, compared with 13 of 25 men who had no adjunctive drainage procedures[6].
All 50 men in that study had mega-liposuction sessions of more than five litres, ranging from eight to 12 litres, with tumescent infiltration[6]. The study was a prospective analysis in a private practice, and the participants had a mean body mass index of 29[6].
The authors concluded that drainage procedures and drain placement are effective methods for minimizing seroma formation and enhancing recovery[6].
In abdominoplasty patients, drainless lipoabdominoplasty with progressive tension sutures had less seroma than drain-based lipoabdominoplasty[15]. The seroma rate in the progressive tension suture group of that abdominoplasty study was 2.6%[15].
For background on this topic, see Adits and Open Drainage.
Ask your surgeon whether drains or other drainage procedures are planned for your operation, and how they will be cared for.
In one pilot study, kinesio taping after flank liposuction was beneficial in reducing swelling and pain, with significant differences in swelling at 14 and 21 days and in pain at seven, 14 and 21 days[1].
The tape in that study was applied to the right abdominal flank of all 52 patients immediately after surgery, and bruising in the taped area differed significantly at seven days[1].
In women with chronic arm lymphedema after breast cancer, liposuction combined with controlled compression therapy reduced arm edema volume completely, compared with a 50% decrease with compression therapy alone[16]. In that lymphedema research, wearing a compression garment after liposuction was necessary to maintain the normalized arm volume[16].
In a series of 870 liposuction cases, early walking after surgery was encouraged to mobilize fluid shifts, speed recovery and help prevent deep vein thrombosis[5].
The same series reported that tumescent fluid made with lactated Ringer's solution clinically showed less tissue edema after surgery than conventional saline[5].
For more on garments, see Compression Garments.
Ask your surgeon how long to wear a compression garment and whether taping or other measures are recommended for you.
Lipedema is a chronic disease of the subcutaneous fat of the limbs in women, characterized by bilateral swelling of the legs or arms, bruising and pain[17].
A meta-analysis of seven studies found significant improvements in spontaneous pain, edema, bruising, mobility and quality of life after liposuction in lipedema patients, although over half still required conservative therapy after surgery[18].
In a randomized trial of women with lipoedema, 68% of patients assigned to liposuction achieved a reduction in leg pain of at least two points after 12 months, compared with 8% assigned to conservative therapy[19]. In that lipoedema trial, adverse events occurred in 124 of 265 patients (47%) who had liposuction, and 20 (8%) were rated as serious[19].
In 20 patients with persistent nonpitting edema after lymphovenous anastomosis for lymphedema, indocyanine green-guided liposuction significantly reduced the excess limb volume[20].
For more on this condition, see Treating Lipedema with Liposuction.
Life-threatening complications reported after liposuction include necrotizing fasciitis, deep vein thrombosis and pulmonary embolism[8].
Deep venous thrombosis, which is associated with pulmonary embolism and death, is described as the most frequent serious complication of liposuction[21]. Venous thromboembolism was rare in a meta-analysis of 29,368 liposuction patients, at 0.017%[2].
In one reported case, fever, rapid breathing, low blood oxygen and adult respiratory distress syndrome developed within 48 hours of extensive liposuction, and the cause was believed to be fat embolism[22]. The authors stressed that awareness of this life-threatening complication is important so that prompt and appropriate treatment can begin[22].

Swelling, bruising and pain often occur at the treated area after liposuction, especially in the first weeks after surgery[1]. Ask your surgeon what amount of swelling to expect after your own procedure.
A meta-analysis of 29,368 liposuction patients found a seroma prevalence of 0.65%[2]. A systematic review of high-definition liposuction reported seroma in 3.3% of 6,964 patients[3].
In one prospective study of very large-volume liposuction in 50 men, seroma developed in 4 of 25 men who had drainage procedures and in 13 of 25 who did not[6].
Contact your surgeon right away if a swelling grows quickly or you develop a fever, and call emergency services if you have chest pain or shortness of breath. Seromas that are not detected promptly can impair the results of liposuction[6].
