What is the most dangerous plastic surgery?

The Brazilian butt lift is often described as the most dangerous plastic surgery because of its specific risk of fatal fat embolism. Earlier BAAPS guidance highlighted a reported mortality rate of around 1 in 3,000 for BBL surgery, while later safety reviews have discussed how safer techniques may reduce risk.

A Brazilian butt lift involves fat grafting. Fat is removed from one part of the body, often through liposuction, and injected into the buttocks to change their size or shape. The danger is that fat can enter major blood vessels if it is injected too deeply.

The BAAPS statement on Brazilian Buttock Lifts highlighted the 1 in 3,000 mortality figure and warned about fat being injected into large veins. The BAAPS Gluteal Fat Grafting Safety Review explains that BBL has been associated with pulmonary fat embolism and that safety depends heavily on technique.

BAAPS has also warned that the buttock area is anatomically complex and that fat embolism, sepsis, severe bleeding and even death can occur with buttock augmentation procedures. You can read the BAAPS call for urgent regulation of BBL procedures.

Why are some plastic surgery procedures more dangerous than others?

Some plastic surgery procedures are more dangerous because they involve deeper tissue, larger areas of the body, longer operating time or higher strain on the body during recovery. Risk also increases where patients are unsuitable, aftercare is poor or the surgeon lacks the right experience.

Any cosmetic procedure can carry risks. However, more invasive surgery procedures may involve:

• General anaesthetic
• Longer surgery
• Larger wounds
• More blood loss
• Greater risk of infection
• Blood clots
• Fluid buildup
• Nerve damage
• Tissue death
• Poor wound healing
• Pulmonary embolism

Plastic surgery safety depends on more than the procedure itself. The patient’s health, body mass index, smoking status, medical history, surgeon skill, clinic standards and aftercare all matter.

Higher-risk cosmetic surgery procedures compared

The table below compares some of the most dangerous plastic surgery procedures and the complications they may involve. UK sources do not provide one single comparable death-rate figure for every procedure, so the table separates reported figures from broader risk guidance.

Why is a Brazilian butt lift considered dangerous?

A Brazilian butt lift is considered dangerous because it involves transferring fat into the buttocks, where large blood vessels are present. If fat is accidentally injected into or below the muscle, it may enter the bloodstream and travel to the lungs or heart.

This can cause a fat embolism, which is a medical emergency and can be fatal. BAAPS has said that BBL deaths appear to stem from fat being injected into veins, causing emboli to travel to the heart or lungs. You can read the BAAPS article on BBL safety.

Brazilian butt lift risks can include:

• Fat embolism
• Pulmonary fat embolism
• Infection
• Sepsis
• Severe bleeding
• Tissue death
• Skin necrosis
• Poor shape or asymmetry
• Need for revision surgery

BAAPS guidance has moved towards safer superficial fat placement and ultrasound guidance, but this does not mean BBL surgery is risk-free. Patients should be wary of any provider who minimises the dangers involved or offers a BBL outside a proper clinical setting.

What is the BBL death rate?

The BBL death rate has previously been reported as around 1 in 3,000 in BAAPS safety material. Later safety review material has discussed lower risk estimates where safer techniques are used, but BBL remains one of the most dangerous cosmetic surgery procedures because of the specific risk of fatal fat embolism.

The safest way to understand the BBL death rate is not as a fixed figure for every patient, but as a serious warning about technique, anatomy and clinical safety. Risk may depend on how the surgery is performed, whether ultrasound guidance is used, the surgeon’s training, the clinic setting and the patient’s health.

Patients should not rely only on online before and after images, social media advertising or low prices. They should ask the surgeon directly about their experience, complication rate, emergency planning and aftercare.

Is a tummy tuck considered high risk?

There is no single reliable tummy tuck death rate UK figure that applies to every patient. However, US and international studies suggest that death after abdominoplasty is rare but has been reported.

A literature review on abdominoplasty complications states that older published series reported mortality of 0.04% to 0.16%, although it notes that death was rarely reported and was not mentioned in more recent series. This is roughly equivalent to 1 in 2,500 to 1 in 625 procedures. You can read the abdominoplasty complication review on PubMed Central.

A 2006 national survey on abdominoplasty and abdominal contour surgery reported a mortality rate of 1 death per 7,314 procedures. However, this was survey-based and should be treated cautiously rather than used as a definitive current rate. You can read the 2006 abdominoplasty survey on PubMed.

Another US outpatient cosmetic surgery mortality study found that, among reported outpatient cosmetic surgery deaths, 54.8% occurred after abdominoplasty, either alone or combined with other procedures. This does not give a procedure-specific tummy tuck death rate, but it supports why abdominoplasty is often treated as one of the higher-risk cosmetic surgery procedures in mortality discussions. You can read the outpatient cosmetic surgery mortality study on PubMed.

The more useful point for patients is that tummy tuck surgery can carry serious risks, including blood clots, pulmonary embolism, infection and poor wound healing. Proper suitability checks, safe surgical technique and aftercare are essential.

Why can liposuction be dangerous?

Liposuction can be dangerous because it removes unwanted fat through a cannula and may affect fluid balance, blood vessels, soft tissue and internal structures. Larger-volume liposuction and combined procedures can carry higher risk than small, localised treatment.

Possible liposuction complications include:

• Infection
• Bleeding
• Fluid imbalance
• Uneven skin texture
• Nerve damage
• Organ injury
• Blood clots
• Pulmonary embolism
• Fat embolism
• Significant scarring

The NHS liposuction guidance lists pulmonary embolism as a possible liposuction risk. The BAPRAS liposuction guide explains that liposuction removes pockets of fat using a cannula inserted through small incisions.

Liposuction should not be treated as a simple weight-loss procedure. The NHS says it is not a treatment for obesity and will not remove cellulite or stretch marks. It should only be performed after proper suitability checks.

Are body lifts and thigh lifts risky?

Body lifts and thigh lifts can be risky because they often involve large areas of skin and soft tissue. They may be used after major weight loss where there is excess skin, but they can involve longer operating time and a higher chance of wound complications.

BAPRAS body contouring risk guidance says body contouring surgery carries a high risk of developing a complication. It also explains that blood clots in the legs can migrate to the lungs and that this can occur after prolonged surgery.

Body lifts and thigh lifts may carry risks such as:

• Wound breakdown
• Infection
• Bleeding
• Fluid buildup
• Poor wound healing
• Nerve damage
• Scarring
• Blood clots
• Pulmonary embolism

These procedures can be harder to recover from because they affect movement, sitting, walking and daily activity. The more extensive the surgery, the more important it is that the patient is properly assessed and given clear advice about recovery time.

What is the safest plastic surgery?

There is no completely safe plastic surgery. Lower-risk cosmetic surgery procedures are usually shorter, less invasive, performed on suitable patients and carried out by experienced surgeons in regulated settings.

Safe plastic surgery depends on:

• Proper suitability assessment
• Clear informed consent
• A qualified surgeon
• A registered clinic or hospital
• Safe anaesthetic care
• Hygiene and infection control
• Good aftercare
• Clear emergency planning

Non-surgical treatments such as dermal fillers may involve minimal downtime, but they are not risk-free. Permanent fillers, for example, can cause long-term problems if placed incorrectly or if complications are not treated properly.

Why UK regulation matters for cosmetic surgery safety

UK regulation matters because cosmetic surgery is usually carried out privately, and patients must take care when choosing where and by whom surgery is performed. Independent hospitals and clinics providing cosmetic surgery in England must be registered with the Care Quality Commission.

The NHS guidance on choosing who will do your cosmetic procedure advises patients to check that a clinic or hospital is registered with the CQC. The CQC cosmetic surgery guidance also advises patients to check who will provide their care and whether the service is regulated.

Professional guidance is also important. The GMC cosmetic interventions guidance says patients should be given enough time and information before deciding whether to have a cosmetic procedure. The Royal College of Surgeons’ cosmetic surgery guidance advises patients to take at least two weeks between consultation and surgery.

What should surgeons check before higher-risk cosmetic surgery?

Before higher-risk cosmetic surgery, surgeons should check whether the patient is suitable for the procedure and whether the risks are acceptable. This is especially important for dangerous plastic surgeries such as BBL, tummy tuck, liposuction, body lifts and thigh lifts.

A surgeon should consider:

• Medical history
• Current medication
• Smoking or vaping
• Body mass index
• Previous surgery
• Risk of blood clots
• Mental health and expectations
• Skin quality
• Wound healing risk
• Whether the patient understands the risks
• Whether safer alternatives are available

The Royal College of Surgeons’ professional standards for cosmetic surgery explain that patients should be well informed about the risks and likely outcome before they consent to cosmetic surgery. Patients should be told what the surgery can achieve, what it cannot achieve, and what could go wrong.

When can complications become cosmetic surgery negligence?

Complications can become cosmetic surgery negligence if the surgeon or clinic failed in their duty of care and this caused avoidable harm. A serious complication does not automatically prove negligence, but poor assessment, poor technique or poor aftercare may support a claim.

Negligence may include:

• Poor suitability assessment
• Failure to explain health risks
• Failure to obtain informed consent
• Poor surgical technique
• Unsafe hygiene
• Performing surgery on an unsuitable patient
• Failure to monitor symptoms
• Failure to act on infection, blood clots or tissue death
• Poor aftercare advice
• Failure to escalate serious complications

Botched cosmetic surgery may leave patients with pain, scarring, infection, asymmetry, nerve damage, tissue damage or the need for corrective surgery.

What should you do if you suffer complications after plastic surgery?

If you suffer serious complications after plastic surgery, seek medical help as soon as possible. Symptoms such as chest pain, breathlessness, severe swelling, spreading redness, discharge, fever, worsening pain or darkened skin should be treated urgently.

You should also contact your clinic or surgeon, explain your symptoms and ask for clear advice. If you cannot reach the clinic, or your symptoms are severe, contact your GP, NHS 111 or emergency services depending on how serious the situation is.

It can help to keep:

• Photographs of the injury
• Consent forms
• Clinic letters
• Aftercare instructions
• Messages with the clinic
• Receipts and payment records
• Medical records
• A timeline of symptoms and appointments

This evidence may help show whether the complication was a recognised risk or the result of negligent treatment. You can also read our guide on how to prove clinical negligence.

Can you claim for negligent cosmetic surgery?

You may be able to claim for negligent cosmetic surgery if your surgeon or clinic breached their duty of care and this caused avoidable harm. A claim is not based on disappointment alone. It needs evidence that the standard of care fell below what was expected.

Compensation may account for pain, scarring, corrective surgery, lost earnings, travel costs, care needs and psychological impact. The amount depends on the injury, its long-term effect and the financial losses caused.
