Cryolipolysis, the fat-freezing technique behind the CoolSculpting system, uses targeted cold to trigger the death of fat cells while sparing surrounding tissue[1][2]. In one prospective study of 60 healthy women, two sessions on the abdomen reduced fat-layer thickness by a mean of 1.25 cm at 3 months[3]. For lipedema, the German S1 guideline names complex physical therapy, liposuction and plastic surgery, diet, and physical activity as treatment mainstays, with psychotherapy if necessary, and cryolipolysis is not among them[4].
Below, each finding is set out with the group it comes from, so you can judge for yourself how far it applies to lipedema.

Lipedema is a chronic, progressive disease that mainly affects women and causes a disproportionate increase in fat tissue under the skin, particularly in the legs[5].
The German S1 guideline describes a symmetrical increase in fat under the skin of the arms and legs that is in marked disproportion to the trunk, together with swelling (edema), easy bruising and increased tenderness[4]. Other reviews note that the hands and feet are spared[6][7]. In lymphedema, by contrast, the most distal body parts are always more severely affected, while in lipedema the most distal parts remain unaffected[8][9].
A US consensus guideline calls lipedema a loose connective tissue disease, marked by nodular and fibrotic fat on the buttocks, hips and limbs, that develops at times of hormone, weight and shape change such as puberty, pregnancy and menopause[10]. One review notes that tissue studies highlight adipocyte hypertrophy (enlarged fat cells), increased fibrosis and angiogenesis (new blood vessel growth)[11].
Lipedema is described as an adipose disorder distinct from obesity, and a 1991 overview calls it a distinct illness rather than just a disturbance in how fat under the skin is distributed[12][13].
Lipedema is often misdiagnosed as obesity or lymphedema, and a 2026 systematic review says this misdiagnosis delays care[14][15]. The diagnosis is made on clinical grounds, and one review notes that no specific biomarker has yet been found[16]. Researchers have proposed ultrasound cutoff values for tissue thickness to help diagnose lipedema in the legs and in the arms[17][18].
A US consensus guideline states that lipedema tissue is difficult to reduce by diet, exercise or bariatric surgery[10]. One review adds that weight loss measures have minimal effect on the abnormal body fat distribution in lipedema[19]. Another review warns that misdiagnosis as obesity or lymphedema leads to ineffective treatments such as weight loss programs and bariatric surgery[20]. For more on this topic, read our guide to liposuction and weight.
Cryolipolysis cools fat tissue to trigger apoptosis, the death of fat cells, while sparing surrounding tissues, and the damaged cells are then removed by macrophages[1]. A 2009 review describes a gradual thinning of the fat layer over a period of two to four months and frames the method as non-invasive fat reduction for areas of local fat accumulation[21].
Cryolipolysis received US Food and Drug Administration clearance for fat reduction in the abdomen, flanks and thighs[22]. A 2016 pilot study described the upper arms as an off-label indication for cryolipolysis at that time[23]. See also our guide to non-surgical fat treatments and our comparison of liposuction and fat freezing.
Across 19 studies in one systematic review, average reductions ranged from 14.67 percent to 28.5 percent by caliper measurement and from 10.3 percent to 25.5 percent by ultrasound[24]. In another systematic review, 295 patients had objective data, and the mean reduction of subcutaneous tissue was 19.55% relative to a designated control site, measured a mean of 3.83 months after treatment[25].
Note the group behind each figure from the individual studies:
One evidence-based review of 32 reports concluded that most lacked rigorous scientific methodology in study design or outcome measurement, and it noted concerns about photographic documentation, conflicts of interest and commercial bias[29].
One report describes cryolipolysis delivered with ice packs for lipoedematous scalp, with subjective and objective relief[30]. Ask your surgeon whether any cryolipolysis results have been published for lipedema of the legs or arms.
One systematic review of 19 studies noted only mild, short-term side effects such as skin redness (erythema), swelling and pain, and described paradoxical adipose hyperplasia in one patient[24]. In another review of 1445 patients with reportable safety data, 12 patients (0.82%) reported complications, most commonly diminished sensation lasting more than 4 weeks[25].
A case series of patients treated for complications of cryolipolysis lists other underreported side effects, including contour irregularities, skin and soft tissue atrophy and asymmetries[31].
Paradoxical adipose hyperplasia is a rare reaction to cryolipolysis in which fat in the treated area first shrinks and then grows abnormally, beyond its original volume[32]. The first report described a man in his 40s whose treated abdomen gradually enlarged three months after a single cycle, and its authors stated that there was no evidence of spontaneous resolution[33].
A 2025 meta-analysis of 28 studies covering 13,078 patients estimated a pooled incidence of 0.22%, with 29 cases identified (1 in 455 patients), based on evidence it rated as low certainty[34]. The authors of that meta-analysis concluded that the incidence appears higher than manufacturer reports[34].
In the Canadian review, incidence rates at all sites fell by over 75% after newer device models were introduced, and 76.9% of cases were associated with older models[35]. The 2014 report suggested the complication seems more common in men, whereas the 2025 meta-analysis found that sex-based risk differences were not statistically significant[33][34].
In one single-center series of 11 cases, 7 patients were treated surgically, six with liposuction alone and one with liposuction and abdominoplasty, and three of those treated with liposuction required a secondary procedure[38]. The authors advise delaying treatment until the area has softened, which they say normally occurs 6 to 9 months after the cryolipolysis procedure[38]. In another series of four patients, all underwent liposuction, abdominoplasty or both, and none showed signs of recurrence during follow-up[36].
If a treated area grows larger in the months after cryolipolysis, contact your surgeon or the clinician who treated you.
One review states that lipedema treatment generally consists of complex decongestive therapy, and the German S1 guideline lists manual lymphatic drainage, compression therapy, exercise therapy and skin care as the parts of complex physical therapy[16][4]. One review states that current therapeutic options provide only partial symptom relief and remain noncurative[5].
In a randomized controlled trial of 33 women with severe lipedema, all three programs (exercise alone, or exercise with complete decongestive therapy or with intermittent pneumatic compression) improved outcome measurements[39]. When the treatments were compared, complete decongestive therapy added to exercise gave significant improvements in limb volume, pain and physical function[39].
In an industry-sponsored, proof-in-principle randomized trial in women with lipedema and secondary lymphedema, both groups improved in leg circumference and bioimpedance, with more improvement when a pneumatic compression device was added to conservative care[40].
A systematic review of six studies including 115 women with lipedema reported that exercise training seems to improve pain and other symptoms, quality of life, limb volumes and/or circumference and functional performance, with greater effects when combined with ongoing compression therapy[41].
A systematic review of nine dietary studies involving 269 women reported weight loss and fat-mass reduction across studies but concluded that the effects of dietary approaches on lipedema remain unclear[42]. A 2026 systematic review found that ketogenic or Rare Adipose Disorders diets, compression therapy and aquatic exercise were associated with reduced pain and swelling[15].
In a pilot study of 15 women with stage II lower-limb lipedema, a combination of shock wave therapy, mesotherapy and kinesio taping was followed by significant reductions in pain and limb circumference[43]. An update for dermatologists lists compression and non-invasive device therapies, specialized diets, physical rehabilitation and surgery among current approaches, and it calls proposed managements controversial[44].
In a 2026 systematic review of 61 articles, tumescent liposuction showed the strongest evidence for sustained improvement in symptoms, mobility and quality of life[15]. The same review concluded that conservative therapies may provide partial relief, but that tumescent liposuction remains the most effective treatment[15].
A 2024 meta-analysis of seven studies found significant post-operative improvements in spontaneous pain, edema, bruising, mobility and quality of life, but over half of patients still required conservative therapy after surgery[45]. The authors of that meta-analysis conclude that liposuction should be considered an adjunct, experimental therapy rather than a definitive cure[45].
In 63 patients with stage I or II lipedema treated with water-jet-assisted liposuction, all assessed symptoms had decreased significantly after a mean follow-up of 22 months, and the share needing any conservative treatment fell from all patients before surgery to 44% afterward[46].
The German S1 guideline states that surgery is indicated if symptoms persist despite thorough conservative treatment or if findings or symptoms progress, and that morbid obesity, if present, should be addressed before liposuction[4]. A randomized multicenter trial called LIPLEG was designed to allocate 405 women with lipedema to liposuction or complex decongestive therapy in a 2:1 ratio, with leg pain reduction at 12 months as the primary outcome[47].
Consider bringing these questions to a board-certified surgeon:
No: lipedema is described as an adipose disorder distinct from obesity, and it is often misdiagnosed as obesity or lymphedema[12][14]. A US consensus guideline states that lipedema tissue is difficult to reduce by diet, exercise or bariatric surgery[10].
Paradoxical adipose hyperplasia is a rare reaction to cryolipolysis in which fat in the treated area first shrinks and then grows beyond its original volume[32]. A 2025 meta-analysis estimated a pooled incidence of 0.22%, or 1 in 455 patients[34].
The German S1 guideline lists complex physical therapy, liposuction and plastic surgery, diet, and physical activity, with psychotherapy if necessary[4]. It states that surgery is indicated if symptoms persist despite thorough conservative treatment or if findings or symptoms progress[4].
Not according to a 2024 meta-analysis, which calls liposuction for lipedema an adjunct, experimental therapy rather than a definitive cure[45]. It found significant improvements in spontaneous pain, edema, bruising, mobility and quality of life, but over half of patients still needed conservative therapy after surgery[45].
Lipedema is diagnosed on clinical grounds, and no specific biomarker has yet been found[16]. Researchers have proposed ultrasound cutoff values for tissue thickness as an aid to diagnosing lipedema in the legs and arms[17][18].
