Warning signs after surgery: when to see a doctor straight away
Fever, swelling, shortness of breath: which symptoms are normal after cosmetic or obesity surgery and which warning signs need urgent action.
In the first days after an operation a lot feels unfamiliar: pain, tightness, swelling, bruising. Most of this is part of normal healing. What matters is whether things improve from day to day – or get worse.
Especially when you are back home after surgery abroad and your surgeon is far away, you should know the warning signs. This guide helps you judge what is normal, when you need a doctor the same day and when you must call emergency services immediately.
Call 999 or 112 immediately
With these signs every minute counts:
- Shortness of breath or sudden breathlessness
- Chest pain, especially when breathing in
- Heavy bleeding that does not stop with pressure
- Confusion, severe drowsiness or loss of consciousness
- A swollen, painful leg together with breathlessness – possible pulmonary embolism
In these cases, do not wait for a reply from the clinic in Türkiye and do not drive yourself to hospital.
See a doctor the same day
These signs are not always an emergency but should be checked by a doctor the same day – at your GP, via NHS 111 or at an urgent treatment centre or A&E:
- Fever above 38 °C or shivering
- Redness that spreads, feels hot or is painful
- Pus or foul-smelling discharge from the wound
- A wound that opens up
- Sudden, clearly one-sided swelling – for example a breast that quickly becomes larger, hard and painful. This can point to bleeding under the skin (haematoma).
- Pain that is increasing rather than decreasing
- Throbbing pain and swelling in one leg – a possible sign of a blood clot
- Dark, bluish-black discolouration of the skin at the wound edges – a possible sign of poor blood supply
What is normal – the typical course of healing
To recognise warning signs, it helps to know what normal healing looks like. The exact course depends on the procedure, but roughly:
| Period | What is normal |
|---|---|
| Days 1–3 | Noticeable pain that is controlled with painkillers; swelling and bruising increase; tiredness; a slightly raised temperature is possible |
| Days 4–7 | Pain eases; swelling peaks and starts to go down; bruises turn yellow-green |
| Weeks 2–3 | Less pain; swelling continues to go down; numbness in the operated area; slight pulling or itching at the scars |
| Weeks 4–6 | Most everyday activities possible again; some remaining swelling, especially in the evening |
| Months | Scars fade; the final result often only shows after several months |
If in doubt: it is better to be checked once too often.
What to watch for after each procedure
Breast augmentation and breast lift
- Bleeding (haematoma): usually in the first days; one breast quickly becomes larger, hard, tense and painful. Get it checked straight away.
- Infection: redness, warmth, fever, increasing pain – possible even after weeks.
- Fluid leaking or a visible implant through an open wound: see a doctor straight away.
- Capsular contracture: over months or years the breast becomes increasingly hard, misshapen or painful. Not an emergency, but a reason for a specialist check.
Liposuction
- Seroma: a soft, fluctuating swelling caused by a build-up of fluid. Not unusual, but should be checked.
- Infection: redness, warmth, fever.
- Skin changes: dark or blistered patches of skin in the treated area.
- Blood clots: liposuction on the legs or of large areas increases the risk – watch for leg warning signs.
Tummy tuck
- Seroma: more common than after other procedures; swelling in the lower abdomen, often fluctuating.
- Wound-healing problems: especially in the middle of the scar; dark wound edges or a stitch line that opens. Smokers are at particular risk.
- Blood clots: a tummy tuck is one of the procedures with a higher clot risk.
Brazilian butt lift (BBL)
- Sudden breathlessness, chest pain or confusion during or after the procedure can indicate a fat embolism – call 999 or 112 immediately.
- Infection or seroma in the buttock or donor area.
Facelift and facial surgery
- Bleeding: usually in the first hours to days; one-sided, increasing swelling and tightness in the face or neck.
- Breathing problems caused by swelling in the neck: call emergency services immediately.
- Weakness of individual facial muscles should be reported to your surgeon.
Nose surgery
- A nosebleed that will not stop.
- Increasing pain, fever or swelling – possible infection.
Hair transplant
- Spot-like inflammation (folliculitis) is common and usually harmless, but should be checked if it spreads.
- Severe redness, swelling of the forehead, fever or pus: possible infection.
Gastric sleeve and other obesity surgery
After a sleeve gastrectomy there are additional warning signs that can point to a leak along the staple line – a rare but serious complication:
- A racing heart (pulse persistently well above 100) – often the first sign
- Worsening abdominal pain, including pain in the left shoulder
- Fever and feeling generally unwell
- Being unable to drink or constant vomiting
Even being unable to drink enough is a reason to see a doctor straight away after obesity surgery, because of the risk of dehydration. Signs of this are dark urine, passing little urine, dizziness and severe thirst.
Later on, difficulty swallowing, persistent heartburn or vomiting after every meal can also occur. This is not an emergency but should be checked by a doctor.
What to do if something is wrong
- Assess: emergency signs? Then call 999 or 112 straight away.
- Get checked: GP, NHS 111 or A&E.
- Take your documents: surgical report, discharge summary, medication list, implant card.
- Document: dated photos, note your temperature, write down your symptoms.
- Inform the clinic: send photos and findings to the clinic in Türkiye. Many clinics offer video check-ups.
- Keep receipts: invoices and any letters about costs – they may matter later.
What to keep to hand
- Your surgical report and discharge summary – in English
- A list of your medication
- Contact details of your surgeon and the clinic
- Your implant card, if you have implants
- A thermometer
Tell the clinic in Türkiye about any complication – but in an emergency do not wait for their reply. What the NHS will and will not cover in such cases is explained in our guide Complications after cosmetic surgery abroad: will the NHS help?

Emergency: If you have shortness of breath, chest pain or a swollen, painful leg, call emergency services (112 in Europe) immediately.
Frequently asked questions
How much swelling is normal after cosmetic surgery?
Swelling and bruising are normal in the first days and usually settle over weeks. Warning signs are sudden, clearly one-sided or rapidly increasing swelling, severe pain or a hard, tense area.
At what temperature should I see a doctor after surgery?
A slightly raised temperature can occur in the first day or two. With a fever above 38 °C, shivering, or if you feel generally worse, see a doctor the same day.
Should I call the clinic in Türkiye first?
Not in an emergency – call 999 or 112 straight away. For less urgent problems, get checked locally and let the clinic know at the same time so they can follow your progress.
Is fluid under the skin after liposuction or a tummy tuck dangerous?
A fluid collection (seroma) is not unusual after these procedures. It is usually not dangerous but should be checked by a doctor, as it sometimes needs draining and can become infected.
Is it normal for one breast to feel different from the other after augmentation?
Slight differences in swelling and position are common in the first weeks. A breast that suddenly becomes much larger, hard and painful, however, is a warning sign and should be examined straight away.
What should I do if I can't keep anything down after a gastric sleeve?
If you can hardly take in any fluid for several hours or keep vomiting, see a doctor straight away. Dehydration can develop quickly after obesity surgery.
Can I treat the wound myself?
Follow the clinic's care instructions. Do not apply creams or home remedies without checking first, and do not remove dressings or stitches yourself unless you have been told to.
How long after surgery can complications still occur?
Most complications occur in the first days and weeks. Blood clots can still form weeks later, and some problems such as capsular contracture with breast implants may only appear after months or years.
