Body contouring after major weight loss, including GLP-1 medicines

Body contouring is surgery to remove the loose, overhanging skin that often remains after major weight loss, and to reshape the areas underneath. It is usually considered once your weight has been stable for at least 6–12 months, and it is often done in stages rather than in one operation.

Losing a large amount of weight is a significant achievement, whether it came through bariatric surgery, a GLP-1 medicine such as semaglutide (Wegovy) or tirzepatide (Mounjaro), or diet and exercise. Skin that has been stretched for years often cannot shrink back fully, especially after rapid weight loss or in later life. The result can be folds of skin on the abdomen, arms, thighs, back, buttocks and chest that cause rubbing, rashes, difficulty with exercise and clothing, and sometimes low mood.

Surgery can remove much of this skin, but it trades loose skin for scars, which are often long. Recovery takes weeks, and complications are more common than after the same operations in people who have not lost a lot of weight. This guide explains how to judge the timing, what each procedure addresses, how operations are sequenced, and the risks to weigh.

At iQonic, body contouring is led by our consultant plastic surgeons, an NHS consultant plastic surgeon at Chelsea and Westminster Hospital, with Dr Ali Arnaout also performing tummy tucks and liposuction. Suitability is always decided at consultation with your operating surgeon.

Most plastic surgeons advise waiting until your weight has been stable, within a few kilograms, for at least 6–12 months. British plastic surgery guidance for NHS referral uses 12 months of stable weight as a standard, and some NHS funding policies ask for longer.

Weight stability matters for three reasons:

• Accuracy. Your surgeon plans how much skin to remove based on your body now. If you lose more weight afterwards, new laxity appears. If you regain weight, scars can stretch and the shape can change.
• Healing. In the months of active weight loss, your body is in a calorie deficit and may be short of the protein, iron and vitamins it needs to heal.
• Fewer surprises. A stable weight gives a clearer picture of what surgery can achieve and whether it is still what you want.

If you are taking a GLP-1 medicine

If your weight loss came from a GLP-1 medicine, think carefully about your plans for the medicine before surgery, and discuss them with your prescriber. Stability usually means you have reached a steady weight on a maintenance dose, or have stopped the medicine and stayed at a steady weight for some months.

Weight regain after stopping is common. In the extension of the STEP 1 trial, people who stopped semaglutide regained about two thirds of the weight they had lost within a year. If you plan to stop your medicine, it is sensible to see where your weight settles before you have surgery, rather than risk regaining weight soon after it.

After bariatric surgery

After a gastric bypass or sleeve gastrectomy, weight loss usually continues for 12–18 months or more. Most surgeons wait until it has plateaued and has then been stable for 6–12 months. Your bariatric team can help confirm this and check your nutrition.

If you take a GLP-1 medicine, including semaglutide (Wegovy, or Ozempic for type 2 diabetes) or tirzepatide (Mounjaro), you must tell your surgeon and anaesthetist, even if you bought it privately or online. Do not stop taking it before surgery unless your own doctor or anaesthetist tells you to.

These medicines slow the emptying of your stomach. In January 2025 the UK medicines regulator, the MHRA, warned that this can leave food in the stomach even after normal fasting, which increases the risk of stomach contents entering the lungs (pulmonary aspiration) during a general anaesthetic or deep sedation. The Royal College of Anaesthetists endorsed this advice and pointed out that privately prescribed weight-loss medicines may not appear in your medical records unless you mention them.

A UK multidisciplinary consensus statement, published in 2025 by the Association of Anaesthetists, the Royal College of Anaesthetists, the Centre for Perioperative Care and other societies, recommends that for planned surgery:

• patients generally continue their GLP-1 medicine through the period around surgery rather than stopping it
• the anaesthetist carries out an individual assessment of aspiration risk, taking into account the medicine, the dose and recent dose changes, the patient and the operation
• the risks and ways of reducing them are discussed with the patient as a shared decision
• standard fasting instructions are followed
• the anaesthetist may adjust the anaesthetic technique, for example by using a breathing tube or an ultrasound check of the stomach

Guidance has changed over the last few years and differs between countries, so the most important rule is simple: follow the specific instructions given to you by your surgeon and anaesthetist at your pre-operative assessment. If you have recently started the medicine or increased the dose, or you have nausea, vomiting or bloating, say so, because your team may change the plan.

If you have type 2 diabetes, your diabetes medicines and blood sugar will also be reviewed before surgery, because good control reduces the risk of wound problems.

The better your general health going into surgery, the lower your risk of complications. Your surgeon will look at your BMI, nutrition, smoking status, medical conditions and emotional readiness.

BMI

A lower BMI at the time of surgery is linked to fewer complications. In a 2026 study of 1,002 people having body contouring after weight loss, each one-point rise in BMI increased the odds of a complication by about 6%. British guidance for NHS referral uses a current BMI of 28 or below. Private surgeons set their own thresholds based on the procedure and your overall health, and some will operate above this level after discussing the higher risk.

Nutrition and protein

Wound healing depends on adequate protein, iron, vitamins and minerals. After bariatric surgery, and during rapid weight loss on GLP-1 medicines, many people eat far less than before and may be low in protein or micronutrients. Your surgeon may:

• ask you to follow a protein target in the weeks before and after surgery
• arrange blood tests, such as a full blood count, iron studies, vitamin B12, folate and vitamin D
• recommend supplements, or liaise with your bariatric team or GP

Smoking and vaping nicotine

Nicotine narrows blood vessels and substantially increases the risk of wound breakdown and tissue loss. You will be asked to stop all nicotine products, including vapes and patches, for several weeks before and after surgery. British guidance treats active smoking as a barrier to this kind of surgery.

Emotional readiness

Major weight loss changes how you see yourself and how others respond to you. It is common to have mixed feelings about the skin that remains. Surgery can help with physical problems and with how clothes fit, but it will not resolve every feeling about your body. If you have a history of eating disorders, depression or body image concerns, tell your surgeon, who may suggest talking to your GP or a psychologist first.

Each area of the body has its own procedure, and most people need more than one. The table shows the most common options and iQonic’s starting prices where they are published.

• Lower abdomen: Overhanging apron of skin, rashes, loose muscles · Tummy tuck (abdominoplasty) · £10,495
• Abdomen, horizontal and vertical excess: Loose skin from side to side as well as top to bottom · Fleur-de-lis abdominoplasty · £12,750
• Abdomen with residual fat on flanks: Loose skin plus stubborn fat · Lipo-abdominoplasty · £10,250 (one area) to £11,250 (three areas)
• Abdomen, hips, outer thighs, buttocks and lower back: Loose skin all the way round the lower body · Lower body lift
• Upper arms: Hanging skin under the arm (“bat wings”) · Arm lift (brachioplasty) · £10,250
• Inner thighs: Loose skin, chafing, difficulty walking or exercising · Thigh lift
• Breasts (women): Deflation, drooping, nipple position low · Breast lift or reduction, with or without an implant · Breast reduction and lift £10,950; augmentation £9,750
• Chest (men): Excess skin and residual breast tissue · Gynaecomastia surgery with excision · £5,250
• Small areas of residual fat: Localised fat with good skin tone · Liposuction · £4,550 (one area)

A note on the abdomen

After major weight loss, the abdomen is the most common first concern. A standard tummy tuck removes skin from the lower abdomen through a scar low across the hips. If there is a lot of loose skin running horizontally as well, a fleur-de-lis abdominoplasty adds a vertical scar down the middle to tighten the waist. If the laxity continues round to the back and buttocks, a lower body lift (also called a belt lipectomy or circumferential abdominoplasty) treats the whole lower trunk in one operation, with a scar that runs all the way round.

Liposuction on its own is rarely the answer after major weight loss, because the problem is usually excess skin rather than excess fat. Removing fat from under loose skin can make the skin look looser.

A note on the face and neck

Major weight loss can also cause loose skin in the face and neck. A facelift may help. This is usually considered after the body procedures, and is discussed separately with a facial surgeon.

Most people who need several procedures have them in two or more stages, a few months apart. Doing everything at once would mean a very long anaesthetic, more blood loss, a higher risk of blood clots and a much harder recovery.

How your surgeon plans the stages depends on your priorities, your health and which areas are causing the most trouble. Common principles include:

• Trunk first. The abdomen and lower body are often treated first, because this area usually causes the most physical problems and because lifting the lower body can change how the thighs look.
• Opposing pulls in separate stages. Some combinations pull skin in opposite directions, for example an upper body lift and a tummy tuck. These are often separated so the scars are not under tension.
• Time between stages. A gap of at least three months, often three to six, allows you to recover, rebuild your strength and nutrition, and let swelling settle before the next operation.
• Limited operating time. Surgeons tend to limit the length of each operation, particularly after major weight loss. Combining two smaller procedures, such as arms and breasts, is sometimes reasonable; combining several large ones is usually not.

Your surgeon will give you a written plan showing what is proposed at each stage, the expected recovery and the cost of each part, so you can decide how far you want to go. You do not have to commit to every stage at the start. Many people find the first operation deals with what bothers them most and decide about the rest later.

Recovery after body contouring usually takes weeks, not days. Expect to need help at home for at least the first week, and plan for 2–6 weeks off work depending on the procedure and your job.

British guidance for body contouring after weight loss describes a typical course of 1–3 nights in hospital, staying at home for the first week, no driving for at least two weeks, and around six weeks before returning to work and strenuous exercise. The table gives typical ranges for each procedure.

• Tummy tuck: 1 night · 3–4 weeks · 8–12 weeks for core work
• Fleur-de-lis abdominoplasty: 1 night · 4–6 weeks · About 3 months
• Lower body lift: 2–3 nights · 4–6 weeks · 6–8 weeks
• Arm lift: Day case or 1 night · 2–4 weeks · About 6 weeks
• Thigh lift: 1–2 nights · 3–4 weeks · About 6 weeks
• Breast lift or reduction: Usually 1 night · 2–3 weeks · About 6 weeks

What to expect during recovery:

• Drains may be placed for a few days to remove fluid.
• Compression garments are usually worn for around six weeks to reduce swelling and support the tissues.
• Walking from the first day helps reduce the risk of blood clots. You may also be given blood-thinning injections and stockings.
• Posture: after a tummy tuck or lower body lift, you will walk slightly bent at first to take tension off the scar.
• Swelling takes several months to settle fully, and scars take 12–18 months to mature.

iQonic provides a comprehensive aftercare programme, with follow-up by your surgeon’s team. You can reach your care team 24/7 through the Adoreal app.

Complications are more common after body contouring following major weight loss than after cosmetic surgery in people who have not lost a lot of weight. Many are minor and can be treated without further surgery, but you should go into surgery expecting that some healing problems are possible.

The evidence gives a sense of scale:

• A 2021 systematic review of 25 studies of body contouring after bariatric surgery found an overall complication rate of 31.5%. Seroma (a collection of fluid under the skin) was the most common, at around 13%.
• British plastic surgery guidance for patients advises that up to half of people will have some complication, though many do not need further surgery.
• A 2026 study of 1,002 people found that complication rates did not differ according to how weight was lost, whether by bariatric surgery, GLP-1 medicine, lifestyle change or a combination. BMI at the time of surgery and diabetes were the factors that predicted problems. Thigh lifts had the highest complication rate of the procedures studied.

Specific risks

• seroma, which may need draining with a needle, sometimes repeatedly
• wound breakdown (dehiscence), particularly where scars meet or are under tension
• infection of the wound
• bleeding and haematoma, occasionally needing a return to theatre
• blood clots in the legs (DVT) or lungs (PE)
• poor or delayed healing, and rarely loss of skin or fat (necrosis)
• wide, raised or stretched scars
• numbness around the scars, which may be long-lasting
• asymmetry, dog-ears (small puckers at the ends of scars) or residual looseness
• lymphatic swelling, particularly after thigh lifts
• anaesthetic risks, including aspiration if you take a GLP-1 medicine and it is not disclosed
• the need for revision or touch-up surgery

How risk is reduced

Reaching a stable, lower BMI, stopping all nicotine, good nutrition, well-controlled diabetes, staging large operations, walking early, wearing compression garments and attending every follow-up all help. Contact your surgeon’s team urgently if you notice increasing pain, redness or heat around a wound, a wound opening, fever, sudden swelling on one side, calf pain or swelling, or breathlessness.

Body contouring can remove much of the loose skin and improve shape and comfort, but it leaves long, permanent scars and cannot make skin behave as if weight had never been lost.

• Scars: they are placed where clothing can hide them where possible, but they are long. A lower body lift leaves a scar around the waist; an arm lift leaves one along the inner arm; a thigh lift one along the inner thigh.
• Some looseness can return: skin that has been stretched for years often has less elasticity, so some laxity may return over the first year. This is one reason for small revisions.
• Weight matters after surgery too: maintaining a stable weight protects the result.
• Function often improves: many people find exercise, hygiene and clothing easier once overhanging skin is removed.

Your surgeon will show you where your scars would be and discuss what they are likely to look like. You can see examples on our before and after page.

Body contouring after weight loss is rarely funded by the NHS, and when it is, the criteria are strict and vary by area. Removing skin for appearance alone is not funded.

Local NHS commissioners (integrated care boards) set their own policies. As an example, one English policy funds body contouring only in exceptional cases of strong clinical need. Its criteria include a documented starting BMI above 40 and a current BMI below 25 (or a large proportional loss for people starting above 50) with at least two years of stable weight, or recurrent infections under skin folds or ulceration that has not responded to treatment. British plastic surgery commissioning guidance sets out broadly similar principles, including 12 months of stable weight and a current BMI of 28 or below.

If you think you might meet local criteria, speak to your GP or bariatric team. An individual funding request may be possible in exceptional circumstances. Many people choose private surgery because they do not meet the criteria or do not want to wait.

The cost of body contouring depends on which areas are treated, whether procedures are combined or staged, and how long you stay in hospital. At iQonic, a tummy tuck starts from £10,495, fleur-de-lis abdominoplasty from £12,750 and an arm lift from £10,250. Prices for lower body lift and thigh lift are given after consultation.

If you need several stages, your surgeon will give you a written plan with a separate quote for each, so you can see the total and decide at your own pace. Quotes are valid for three months. Information on spreading the cost is on our pricing and finance page.

Your consultation is in person at 15 Harley Street, London, with the surgeon who would operate: usually Dr Ali Arnaout. It costs £100. If you would like to talk things through first, a virtual consultation with a patient advisor is free. Surgery takes place at partner hospitals in London. Bring details of your weight history, any bariatric surgery and any medicines you take, including GLP-1 medicines bought privately. After your first consultation you will have at least 14 days to reflect before you give consent, with further consultations always available. Read more on your journey, or book a consultation.
