Liposuction is a common procedure, but it is still surgery and carries risks. General risks include bleeding, infection, blood clots and reactions to anaesthetic; liposuction-specific risks include contour irregularities, asymmetry, numbness, fluid collections and, rarely, injury to deeper structures. Careful selection, sensible limits on the volume removed, an accredited hospital and good aftercare all reduce these risks.
General surgical risks
- Bleeding and haematoma: some bruising is normal; a collection of blood that needs draining is uncommon. Stopping certain supplements and medicines before surgery, as advised, lowers the risk.
- Infection: the small incisions rarely become infected; sterile technique, antibiotics where appropriate and good wound care help.
- Blood clots (VTE): deep vein thrombosis or a clot on the lung is a serious risk after any surgery. Early walking, compression stockings and, for some patients, blood-thinning injections reduce it.
- Anaesthetic: reactions are rare; you will meet a consultant anaesthetist beforehand to review your health.
Risks specific to liposuction
- Contour irregularities: dents, ridges or waviness can occur, particularly if too much fat is removed or the skin is thin.
- Asymmetry: small differences between sides are common, as no body is symmetrical to begin with.
- Loose skin: if skin elasticity is poor, it may not retract fully after fat removal.
- Seroma: a pocket of fluid under the skin may need draining in clinic.
- Numbness and altered sensation: usually improves over months, but can occasionally persist.
- Skin changes: discolouration, or burns with energy-assisted techniques such as Vaser, are uncommon.
- Fluid and fat embolism: rare but serious complications, one reason why large-volume removal is limited and carried out in hospital.
- Injury to deeper structures: very rare, such as perforation of the abdominal wall, and minimised through careful technique and assessment of hernias beforehand.
How risks are reduced
Safety begins at consultation. Mr Nassab will take a full medical history, review medications, check for hernias or previous surgery in the treatment areas and assess your skin. Liposuction is performed in a CQC-registered hospital with a consultant anaesthetist. The amount of fat removed in one session is kept within safe limits, and larger plans may be staged. Stopping smoking and nicotine products well before surgery, reaching a stable weight and disclosing all medications, including weight-loss medication and herbal supplements, all make a difference.
What is normal after liposuction
In the first few days it is normal to have bruising, swelling, soreness like a heavy workout and blood-stained fluid leaking from the incisions, which is why absorbent pads are used. Over the following weeks you may notice lumpiness, hardness or numbness in treated areas, and itching as sensation returns. Swelling can fluctuate, especially by the end of the day. These changes typically settle gradually over three to six months.
Symptoms that need attention
- Fever, spreading redness, increasing pain or foul-smelling discharge: contact the surgical team the same day.
- A rapidly enlarging, tense swelling in one area: contact the surgical team urgently.
- Sudden one-sided leg swelling or calf pain: same-day GP or NHS 111.
- Chest pain, breathlessness or coughing blood: call 999.
- Confusion, dizziness or feeling very unwell: seek urgent medical help.
Your own risk profile
Individual factors change the balance of risk. Smoking, diabetes, a higher body mass index, previous abdominal surgery, a personal or family history of clots and some medications all raise it, and each is considered when planning. Combining liposuction with other procedures lengthens the operation, which is weighed carefully. Being honest at consultation allows the plan to be adjusted to keep you as safe as possible.
Keeping the risks in perspective
Serious complications after liposuction are uncommon when surgery is performed by a qualified plastic surgeon in an accredited hospital, but they cannot be removed entirely. Taking risk seriously means understanding it before you decide, following pre-operative advice closely and attending follow-up. Mr Nassab will talk through the risks that apply to you personally, and you will receive written information to take away.

Cosmetic surgery is for adults aged 18 and over.
Frequently Asked Questions
Is liposuction a safe operation?
It is a well-established procedure, and most people recover without significant problems. Like all surgery, it carries risks, which are reduced by careful selection and an accredited hospital.
What is the most common problem after liposuction?
Minor contour irregularities and asymmetry are among the more frequent concerns, alongside prolonged swelling and temporary numbness.
Does Vaser liposuction carry different risks?
Vaser uses ultrasound energy, so there is an additional small risk of skin burns, which is reduced with skin protectors and careful technique.
How is the risk of blood clots managed?
Through early walking, compression stockings, staying hydrated and, for some patients, blood-thinning injections, based on an individual risk assessment.
Can liposuction damage my skin?
Skin damage is uncommon, but thin skin or over-aggressive removal can lead to irregularities. A measured approach reduces this risk.
