Numbness after liposuction is expected and usually temporary: reduced skin sensation is an expected effect of suction-assisted liposuction, and it usually returns to normal within several weeks to months[1]. In a study of 21 liposuction patients, 89 percent had recovered normal sensation ten weeks after surgery[1]. Longer-lasting numbness was more frequent in women with advanced lipedema who had lower-leg liposuction[2].
Yes, reduced skin sensation is regarded as an expected effect after suction-assisted liposuction[1]. Doctors call this reduced sensation hypesthesia[1].
Researchers studying lower-leg liposuction note that liposuction may cause temporary changes in skin sensation[2]. A study of patients with Dercum's disease likewise describes sensory change after liposuction as a well-known side effect[3].
Sensory changes are also reported when liposuction is combined with other operations[4][5]. In 177 patients treated for enlarged male breast tissue (gynecomastia) with liposuction plus removal of gland tissue through a small incision around the areola, transient skin sensory changes occurred in 4 patients[4].
Four transient disturbances of lower-lip sensation were recorded among twenty patients who had suction lipectomy under the chin through the mouth, combined with chin or jaw bone surgery[5]. All complications in that group had resolved by the long-term follow-up, which took place at least five years after surgery[5].
A systematic review of submental (under-the-chin) liposuction combined with jaw surgery, covering 67 patients, found that sensory changes in the lower lip were the most cited complication, with four cases[6].
In 126 patients treated for cellulite with superficial liposuction using a special cannula combined with fat grafting, numbness was among the most common complications, although the overall complication rate was low[7]. Among 53 patients treated for limb lymphedema with lymph node transfer combined with suction-assisted lipectomy, the minor complications included hematoma and sensory changes[8].
After liposuction, sensory changes usually return to normal within several weeks to months[1].
One study objectively tested skin sensation in 21 liposuction patients at 102 sites on the abdomen, flanks, thighs and inner knees, before surgery and at two, six and ten weeks afterwards[1]. On average, areas treated with traditional suction-assisted liposuction improved to normal sensation by six weeks[1]. Areas treated with ultrasound-assisted liposuction took ten weeks on average to recover[1].
At ten weeks in that study, 89 percent of the liposuction patients overall and 90 percent of the ultrasound-treated patients had recovered normal sensation[1].
In a prospective study of lower-leg liposuction, numbness that was still present at twelve months was seen in 3.3 percent of women having cosmetic liposuction[2].
Sensory recovery after a combined operation has been mapped in 60 patients who had liposuction all the way around the torso (360-degree liposuction) together with a tummy tuck (lipoabdominoplasty)[9]. In that group, 93.3 percent showed sensory impairment at one month[9]. Residual sensory deficits persisted in 72.5 percent at three months, 55.0 percent at six months and 21.7 percent at twelve months[9].
The authors of that study concluded that sensory loss is an almost universal early effect of lipoabdominoplasty but typically resolves within twelve months[9].
A tummy tuck on its own can cause lasting sensory changes: in 14 patients who had a standard full abdominoplasty, sensory changes found at least one year later were concentrated around the belly button and lower abdomen[10]. Sensation of the thighs did not decrease significantly in that tummy tuck study[10].
The presumed mechanism is direct trauma to the peripheral nerves from the suction cannula used during liposuction[1].
A study of patients with Dercum's disease, a condition marked by pronounced pain in the fat tissue, also describes sensory change after liposuction as probably caused by mechanical trauma to the nerves[3].
With ultrasound-assisted liposuction, there is also a well-known potential for demyelination of peripheral nerves caused by cavitation[1]. Even so, a randomized side-to-side trial in 28 patients found that patient-reported numbness and soreness did not differ significantly between tumescent liposuction with and without internal ultrasonic assistance[11].
Disease severity, the amount of tissue removed and a higher body mass index have each been linked to longer-lasting numbness[2][9].
Lipedema is a fat tissue condition in which pain is a central characteristic[12]. In a prospective study of 90 women having lower-leg liposuction, numbness at twelve months was seen in 3.3 percent of cosmetic patients, 5 percent of women with stage I lipedema, 15 percent with stage II and 25 percent with stage III[2].
In that lower-leg study, aspirated volume increased with disease stage and correlated with persistent reduced sensation or abnormal sensations (paresthesia)[2]. The authors concluded that disease severity and aspirated volume, not surgical technique, were the main determinants of numbness after surgery[2].
A separate study of 21 liposuction patients found that the severity of numbness was not correlated with larger aspiration volumes or with longer ultrasound exposure time per site[1].
After combined liposuction and tummy tuck, higher body mass index, a standard dissection that removes Scarpa's fascia, and a resection weight greater than 1000 grams were independent predictors of persistent numbness[9]. Preserving Scarpa's fascia significantly improved sensory outcomes in that study[9].
In 39 patients with Dercum's disease, thermal and vibration thresholds showed only small differences three and twelve months after liposuction, and none of the differences was statistically significant[3].
Abnormal sensations can persist after liposuction: in a study of lower-leg liposuction in women with and without lipedema, persistent reduced sensation and paresthesia were correlated with larger aspirated volumes[2].
In the side-to-side trial of tumescent liposuction, patient-reported soreness did not differ significantly between the sides treated with and without internal ultrasonic assistance[11].
In lipedema, liposuction can reduce pain: women with lipedema reported substantial improvements in pain, at rates of 85 to 95 percent, after lower-leg liposuction[2]. A review of lipedema pain states that liposuction has been shown to have a long-term effect on pain[12].
Severe or persistent pain and dysesthesia are listed among the more serious complications of cryolipolysis, a non-surgical body contouring treatment[13].
If you notice burning, shooting or electric-shock pain after liposuction, describe it to your surgeon.
Yes, numbness or paresthesia is one of the most common adverse events after cryolipolysis, a non-surgical body contouring treatment[13].
A meta-analysis of 30 studies with 3158 participants reported adverse-event rates of 49.5 percent for numbness, 28.8 percent for pain and 15.2 percent for tingling after cryolipolysis[14].
In a small study of cryolipolysis, transient reduction in sensation occurred in six of nine subjects assessed, and all sensation returned by a mean of 3.6 weeks[15]. In a prospective observational study from clinics in Japan, pain after cryolipolysis disappeared within one month, while numbness persisted for approximately three months[16].
In a randomized split-body trial, heating the skin after cryolipolysis made hypesthesia fade almost completely but significantly reduced fat loss[17].
A systematic review of subsurface radiofrequency treatments, which coagulate the fat beneath the skin, found that most patients experienced prolonged swelling and numbness[18]. By contrast, a study of a uniform heating radiofrequency device in twenty Japanese patients observed no sensory changes[19].
Numbness was among the most common adverse events in clinical trials of deoxycholic acid injections for fullness under the chin, and cases of transient neuropraxia have been reported in real-world case reports beyond the trials[20].
Contact your surgeon whenever numbness, burning or pain worries you, and ask how your sensation is expected to recover.

Yes, reduced skin sensation is an expected effect of suction-assisted liposuction[1]. Sensation usually returns to normal within several weeks to months[1].
In a study of 21 liposuction patients, areas treated with traditional suction improved to normal sensation by six weeks on average, and ultrasound-treated areas by ten weeks[1]. At ten weeks, 89 percent of the patients overall had recovered normal sensation[1].
In a study of lower-leg liposuction, numbness at twelve months was seen in 3.3 percent of women having cosmetic liposuction and in 25 percent of women with stage III lipedema[2]. Ask your surgeon how your own risk compares.
In one study, ultrasound-treated areas took ten weeks on average to recover normal sensation, compared with six weeks for areas treated with traditional suction[1]. A side-to-side trial in 28 patients found no significant difference in patient-reported numbness between tumescent liposuction with and without internal ultrasonic assistance[11].
Contact your surgeon right away if pain becomes severe, burning or steadily worse, or if numbness spreads. Call emergency services right away if you have chest pain or shortness of breath.
