A tummy tuck is a major operation, and its main risks include bleeding, infection, fluid collection (seroma), wound-healing problems, blood clots in the legs or lungs, numbness, asymmetry and scarring. Most people recover without serious problems, but the risk is higher in smokers, people with a high BMI and those with certain medical conditions. Careful selection, planning and aftercare aim to reduce every one of these risks.
General surgical risks
- Bleeding and haematoma: a collection of blood under the skin may need a return to theatre. Stopping blood-thinning supplements and some medicines before surgery, as advised, reduces the risk.
- Infection: usually treated with antibiotics; wound hygiene and not smoking help prevention.
- Venous thromboembolism (VTE): a clot in the leg (DVT) that can travel to the lungs (pulmonary embolism). Abdominoplasty carries a relatively higher VTE risk than many cosmetic procedures, so compression stockings, calf pumps during surgery, early walking and, where appropriate, blood-thinning injections are used.
- Anaesthetic risks: general anaesthesia is very safe in healthy people; your anaesthetist will review your health and discuss any specific concerns.
Risks specific to abdominoplasty
- Seroma: fluid can collect beneath the skin in the weeks after surgery. Small collections may settle; larger ones are drained in clinic with a needle, sometimes more than once. Techniques such as internal quilting sutures, drains where used and compression garments aim to reduce this.
- Wound healing problems: the centre of the scar is under the most tension and has the least blood supply, so small areas of delayed healing or skin loss can occur, particularly in smokers.
- Fat necrosis: areas of fat that lose their blood supply can form firm lumps, which often soften over time.
- Numbness: reduced sensation of the lower abdomen is common and may improve over many months, though some numbness can persist.
- Scarring and dog-ears: the scar may widen, thicken or leave small puckers at the ends, which can sometimes be revised.
- Belly button problems: the umbilicus can heal with a scar, narrowing or an unnatural shape.
- Asymmetry or residual fullness: some unevenness or remaining fat may persist.
Who has a higher risk?
Smoking and vaping nicotine significantly increase wound-healing complications; you will be asked to stop well before and after surgery. A higher BMI, diabetes, previous abdominal surgery, a history of blood clots and combining a tummy tuck with several other procedures in one operation can all increase risk. Mr Nassab will review your medical history and may recommend weight loss, further tests or a staged approach before surgery.
How risk is reduced
Safety starts at consultation with an honest assessment of suitability. Surgery takes place in a CQC-registered hospital with an experienced anaesthetist. Blood-clot prevention, careful tissue handling, antibiotics where indicated and a structured recovery plan all contribute. After surgery, walking little and often from the first day, wearing your garment as instructed, keeping wounds clean and attending follow-up appointments help to spot and treat problems early.
What is normal after surgery
Swelling, bruising, tightness across the abdomen and walking slightly bent for the first week or so are expected. Some fluid from drains or wounds in the early days, numbness around the scar and a firm, lumpy feel as the tissues heal are common. Swelling often fluctuates, becoming worse at the end of the day, and can take several months to settle fully.
When to seek help
- Call 999: if you develop chest pain, sudden breathlessness or cough up blood.
- Same-day GP or NHS 111: for sudden swelling or pain in one calf or leg.
- Contact the surgical team the same day: if you have a fever, spreading redness, a foul-smelling discharge or a wound that is opening.
- Contact the surgical team urgently: if one area of the abdomen suddenly becomes very swollen, tense or painful, which may indicate bleeding.
You will be given contact details for the team before you go home, so you know who to call at any time.
Frequently Asked Questions
What is the most common complication after a tummy tuck?
Seroma, a collection of fluid under the skin, is one of the more common problems. It is usually managed by draining the fluid in clinic.
Is a tummy tuck dangerous?
It is a major operation with real risks, including blood clots. In suitable, healthy patients, careful planning and aftercare keep the risk as low as possible.
Is smoking allowed before a tummy tuck?
No. Nicotine from any source increases wound-healing problems. You will be asked to stop well before and after surgery.
Does a tummy tuck cause numbness?
Some numbness of the lower abdomen is common and often improves over months, although some may be long-lasting.
How is a seroma treated?
Small seromas may settle on their own. Larger ones are drained with a fine needle in clinic, sometimes on more than one occasion.
