Cosmetic surgery can enhance the shape, proportion, or appearance of the face and body. A person may also feel more at ease with a long-standing appearance concern after cosmetic surgery. Cosmetic surgery may offer benefits, but no operation is entirely predictable. Understanding the risks of cosmetic surgery is an important part of deciding whether a procedure is right for you.
Although most patients heal without serious problems, no surgeon can guarantee perfection or eliminate every surgical risk. Anesthesia, bleeding, infection, healing difficulties, unexpected reactions, and the body's response to an operation can all cause problems. Some complications are temporary and easy to treat. More serious problems may call for medication, hospital treatment, revision surgery, or ongoing medical follow-up.
In Canada, patients should be clearly informed about expected benefits, important risks, treatment alternatives, recovery needs, and what may happen if they decline surgery. A thorough consultation should provide enough time to review the information and make a decision without pressure. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits.
What Are the Risks of Cosmetic Surgery?
Cosmetic surgery risks include any unwanted medical, functional, or aesthetic outcome linked to an operation. Risk levels vary according to the procedure, surgical method, treatment area, operation length, anesthesia type, and the patient's general health.
Many cosmetic procedures are followed by mild expected side effects. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. A true complication is not the same as an expected side effect. It is a problem that goes beyond the expected recovery process and may require medical treatment.
Potential problems associated with plastic surgery include:
- Bleeding or a collection of blood called a hematoma
- An infection in the incision or deeper surgical tissues
- A collection of fluid called a seroma
- Clots that form in a leg vein or travel to the lungs
- An incision that heals poorly, slowly, or begins to open
- Scars that become prominent, raised, wide, or uneven
- Nerve-related problems, including numbness or unusual sensation
- Loss of skin, fat, or other tissue because of reduced circulation
- Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products
- Unevenness, contour irregularities, or an unsatisfactory appearance
- Functional changes affecting breathing, movement, or feeling
- Additional medical treatment or a revision operation
Serious complications are uncommon, but they are still important to discuss. Uncommon but severe risks can include serious infection, substantial bleeding, damage to an organ, cardiac complications, stroke, pulmonary embolism, lasting disability, or death.
Common Short-Term Effects After Cosmetic Surgery
Some discomfort and physical change are part of normal healing. Patients who understand expected recovery are better able to separate routine symptoms from possible complications.
Soreness After Cosmetic Surgery
Each patient experiences pain differently, and some operations cause more discomfort than others. The surgical site can feel tender, tight, sore, or mildly burning during recovery. Discomfort is normally expected to improve gradually during healing. Prompt medical advice is needed if pain suddenly worsens, begins spreading, or appears with fever, redness, breathing difficulty, or unexpected swelling.
Postoperative Swelling and Bruising
Swelling develops when inflammation allows fluid to collect in and around the treated area. The early result can remain difficult to assess until swelling subsides over the following weeks or months. Bruising occurs when small blood vessels leak beneath the skin. Facial procedures, liposuction, breast surgery, and body contouring can all cause visible swelling and bruising.
Patients are advised to avoid making early judgments about their final appearance. Residual swelling can change shape, symmetry, and skin texture during recovery.
Numbness and Changes in Sensation
During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Temporary changes such as tingling, numbness, tenderness, or reduced sensation may occur after surgery. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. In some cases, changes in sensation may be permanent.
Short-Term Activity Restrictions
Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. Driving, exercise, heavy lifting, swimming, and returning to work may be restricted. Failing to follow activity restrictions may raise the risk of bleeding, swelling, wound breakdown, and other problems.
Medical and Surgical Risks
Bleeding and Hematoma
A limited amount of bleeding around the incision may be expected. Heavier bleeding may create a hematoma, a pocket of blood beneath the skin or within the treated area. Increasing tenderness, firmness, swelling, discolouration, or an abrupt difference between two sides may indicate a hematoma.
Some hematomas can be observed, while others must be drained. In certain cases, the patient may need to return to the operating room.
Infection After Cosmetic Surgery
An infection can develop in the skin, incision, tissue, or around an implant. Possible signs include increasing redness, warmth, swelling, pus-like drainage, worsening pain, fever, chills, or an unpleasant smell.
An infection can require medication, incision care, removal of fluid, or an additional procedure. Removal can be required when infection develops around a breast implant or surgical device. Infection risk and treatment difficulty may increase with smoking, poorly controlled diabetes, inadequate nutrition, or reduced circulation.
Fluid Buildup or Seroma
A seroma develops when a pocket of clear fluid forms under the surgical tissues. Seromas occur more often after operations that leave a broad space under the tissue, including tummy tuck surgery, body lifts, breast procedures, and extensive liposuction.
A minor fluid collection can sometimes disappear as the body reabsorbs it. Repeated drainage may be necessary when a significant seroma develops. Untreated fluid can place pressure on the incision, affect healing, or become infected.
Blood Clot Complications
Deep vein thrombosis, or DVT, occurs when a blood clot forms in a deep vein, often in the leg. When part of a deep vein clot moves into the lungs, it may block blood flow and cause a pulmonary embolism. This is a medical emergency.
Risk may increase with long operations, limited movement, previous blood clots, certain medications, nicotine use, obesity, some medical conditions, and combining multiple procedures. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable.
Delayed or Difficult Wound Healing
A surgical wound may take longer than expected to close or may start to open. Reduced blood supply, infection, tension on the wound, nicotine exposure, certain medications, and medical conditions can interfere with healing.
Treatment for a wound complication can include specialized dressings, antibiotic medication, removal of unhealthy tissue, or another operation. Healing by secondary intention means allowing an open area to close gradually from the inside outward. Healing in this way often takes more time and can result in a more noticeable scar.
Skin or Tissue Necrosis
Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to die. Operations that move, tighten, or lift broad areas of tissue can carry a risk of necrosis. Smoking, vaping, and other nicotine use can greatly increase risk by narrowing blood vessels and reducing tissue oxygen.
Treatment depends on the amount of tissue affected. Possible treatment includes wound management, removal of dead tissue, a skin graft, reconstructive surgery, or revision at a later date.
Anesthesia Risks in Cosmetic Surgery
Depending on the operation, cosmetic surgery can involve local anesthetic, sedating medication, general anesthesia, or multiple methods together. Choosing an anesthesia method requires consideration of the operation, medical background, expected surgical time, and facility.
Possible anesthesia-related problems include:
- Feeling sick or vomiting after anesthesia
- Dizziness, confusion, or prolonged drowsiness
- Throat discomfort or headache
- Unexpected reactions to anesthetic or other medications
- Abnormal blood pressure or irregular heart rhythm
- Breathing difficulties
- Aspiration of stomach contents into the lungs
- Dental, lip, or airway damage
- Severe cardiac, respiratory, or neurological problems
Patients must provide complete information about prescriptions, non-prescription drugs, vitamins, supplements, cannabis, alcohol, nicotine, allergies, earlier anesthesia problems, and medical conditions before surgery. Withholding medical or lifestyle information may increase the risks of anesthesia and surgery.
Scarring and Changes to the Skin
Any procedure that cuts the skin creates a scar. Incisions are often positioned in natural creases, along hairlines, or beneath clothing, although no scar can be removed entirely.
Early scars can be firm, raised, reddish, or more deeply coloured before they mature. Scars may require a year or more to flatten, soften, and become less noticeable. Genetic factors, skin characteristics, pressure on the incision, infection, sunlight, wound care, surgical location, and procedure type all influence the finished scar.
Hypertrophic Scars and Keloids
Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. Keloid tissue spreads past the edges of the initial incision. People with a personal or family history of abnormal scarring should tell their surgeon before surgery.
Possible treatments include silicone products, pressure therapy, copyright injections, laser treatment, or scar revision. Although treatment can make a scar less noticeable, recurrence of abnormal tissue remains possible.
Pigment and Texture Irregularities
Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. Some of these changes resolve over time, while others can last permanently. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
Aesthetic Risks and Unsatisfactory Results
A technically successful operation does not always produce the appearance a patient expected. Individual anatomy, skin flexibility, age, past procedures, scarring, and natural asymmetry all affect healing.
Appearance-related problems may include:
- Ongoing asymmetry
- Irregular or uneven body contours
- Too little or too much correction
- An artificial-looking or over-tightened outcome
- A changing contour as postoperative swelling decreases
- Implant position problems
- Noticeable scars or scars in an unfavourable location
- A return of looseness or sagging with age and time
- Disappointment with an outcome that falls within an acceptable surgical range
Photos, digital simulations, and before-and-after galleries can support discussion, but they cannot guarantee an identical outcome. Each patient has different anatomy and heals in a different way.
The Possibility of Revision Surgery
Revision surgery may be considered when a complication occurs or when the result can be improved. However, another operation brings new risks. Scar tissue can make the procedure more complex, and the tissues may have less blood supply or flexibility than they did before the first surgery.
Before proceeding, patients should understand exactly what is included in the surgeon's or clinic's revision policy. The first surgical fee may not cover a revision surgeon, facility charges, anesthesia, new implants, prescriptions, travel, or lost work time.
Complications by Type of Cosmetic Surgery
Although many operations share common complications, every cosmetic procedure has its own specific risks.
Risks of Facelift and Neck Lift Surgery
Possible problems after a facelift or neck lift include bleeding beneath the skin, nerve damage, changes to the hairline, localized hair loss, tissue loss, uneven contours, altered earlobes, numbness, facial weakness, and noticeable scars. Nicotine use can greatly increase the risk of skin-healing problems.
Risks of Nose Surgery
Potential rhinoplasty complications include long-lasting swelling, bleeding, infection, unevenness, altered smell, contour problems, a hole in the septum, structural collapse, and nasal breathing difficulty. A rhinoplasty result may not fully settle for 12 months or more. Scar formation and altered cartilage can make secondary rhinoplasty more complex.
Blepharoplasty Risks
Blepharoplasty risks include dry or irritated eyes, temporary blurred vision, difficulty closing the eyelids, eyelid malposition, asymmetry, scarring, bleeding behind the eye, and changes in vision. Immediate medical evaluation is needed for intense eye pain or a sudden visual disturbance.
Possible Breast Procedure Complications
Nipple sensation, symmetry, scars, and the ability to breastfeed may be affected by breast augmentation, breast lift surgery, or breast reduction. Hematoma, infection, fat necrosis, poor healing, and altered nipple or areola position are also possible.
Patients with breast implants face additional concerns that can develop over time. Capsular contracture, rupture, deflation, rippling, displacement, rotation, pain, ongoing imaging, and future surgery may occur with breast implants. Patients should not assume that breast implants will remain in place permanently without further care. Health Canada also provides safety information about uncommon conditions linked with certain breast implants, including breast implant-associated anaplastic large cell lymphoma.
Possible Liposuction Complications
Liposuction may lead to dents, surface irregularities, skin looseness, fluid problems, numbness, fluid collection, infection, organ injury, fat embolism, or lidocaine toxicity when local anesthesia is involved. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated.
Tummy Tuck and Body Lift Risks
Tummy tuck and body lift procedures require long incisions and repositioning of broad tissue areas. Risks include seroma, blood clots, infection, skin loss, wound separation, numbness, prominent scarring, and changes to the position or shape of the belly button. Recovery may involve several weeks of limited movement and physical activity.
Possible Fat Grafting Complications
During fat grafting, fat is taken from one body area and placed into a different location. Some of the transferred fat will be absorbed, which can affect volume and symmetry. Additional complications include dead fat tissue, cysts, calcification, infection, oil cysts, and fat entering a blood vessel. The location where fat is injected, such as the face, breasts, or buttocks, affects the type and seriousness of potential complications.
Who May Face Greater Cosmetic Surgery Risks?
Certain medical conditions and lifestyle habits increase surgical risk. A patient may need medical testing, treatment changes, weight management, nicotine cessation, or clearance from another health professional before surgery.
The likelihood of complications may increase with:
- Smoking, vaping, or using nicotine products
- Diabetes with unstable or elevated blood sugar
- Cardiac, respiratory, renal, liver, or vascular conditions
- A clotting or bleeding condition, or previous blood clots
- A high body mass index or significant changes in weight
- Obstructive sleep apnea
- Conditions affecting the immune system
- Inadequate nutrition or serious anemia
- Previous radiation or surgery in the treatment area
- Drugs, vitamins, or supplements that interfere with clotting or tissue repair
- Unrealistic expectations or untreated mental health concerns that affect decision-making
The presence of one or more risk factors does not automatically prevent cosmetic surgery. The surgeon needs to evaluate the level of risk and decide whether health or lifestyle changes are necessary before treatment.
Psychological and Emotional Risks
The effects of cosmetic surgery may be psychological and emotional, not only physical. During recovery, patients can become anxious or discouraged because they look swollen, feel tired, and cannot resume normal activities. A short period of sadness or emotional difficulty after surgery is sometimes known as postoperative blues.
More serious dissatisfaction can occur when expectations do not match what surgery can realistically achieve. Although surgery can alter appearance, it cannot promise self-confidence, fix relationships, ensure professional success, or resolve wider life difficulties.
The patient's motivation for considering surgery should be discussed during an appropriate assessment. Possible warning signs include outside pressure, ongoing dissatisfaction despite multiple operations, severe concern about a minor feature, and unrealistic beliefs about total life transformation.
Intense and persistent concern about perceived physical defects may be a sign of body dysmorphic disorder, a recognized mental health condition. An operation may fail to resolve the deeper psychological distress. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation.
Ways to Lower Cosmetic Surgery Risks
Cosmetic surgery always carries some risk, yet careful planning can reduce the likelihood of complications.
- Work with a properly trained physician whose practice includes the cosmetic operation you are considering.
- Confirm through your province or territory's college of physicians and surgeons that the doctor is licensed and in good standing.
- Find out which facility will be used and whether it has suitable emergency plans, safety standards, and infection prevention measures.
- Disclose your entire health history, including previous surgery, allergies, medications, supplements, alcohol, cannabis, and nicotine use.
- Carefully follow all directions related to eating, drinking, preoperative tests, medication adjustments, and nicotine cessation.
- Arrange a responsible adult to drive you home and assist during early recovery when required.
- Review the expected healing schedule before arranging employment, trips, strenuous activity, or important occasions.
- Follow-up care should not be skipped, and abnormal changes should be reported without delay.
- Your recovery should not be compared with social media images, promotional content, or another person's timeline.
- Allow swelling and scar tissue to settle fully before considering corrective surgery.
Finding a Qualified Canadian Cosmetic Surgeon
Medical regulation in Canada is handled at the provincial and territorial level. Patients can search the public register of the applicable college of physicians and surgeons to confirm a doctor's licence, registered specialty, and available practice information.
Another useful question is whether the doctor holds plastic surgery certification from the Royal College of Physicians and Surgeons of Canada. Certification is one useful qualification to review, but patients should also consider experience with the specific procedure, complication management, communication, surgical setting, and follow-up care.
Useful questions for a cosmetic surgery consultation include:
- What training and certification do you have?
- How often do you perform this procedure?
- Based on my health, goals, and anatomy, is this procedure suitable for me?
- Which problems do your patients experience most often after this operation?
- What rare but serious risks should I understand?
- Which medical professional will administer and monitor my anesthesia?
- Who should I contact if I experience a complication outside normal clinic hours?
- What emergency plan is in place if I need urgent medical treatment?
- What follow-up visits are included?
- Could I face extra surgeon, facility, anesthesia, medication, or revision fees?
Understanding Informed Consent
Informed consent involves more than placing a signature on a document. It should be a continuing conversation that allows the patient to decide freely after receiving adequate information.
The consent process should cover the nature of the procedure, expected benefits, important risks, reasonable alternatives, recovery, limitations, and what could happen without treatment. Risks that are especially relevant to the patient's health, job, lifestyle, or personal priorities should also be discussed.
Patients should have enough time to review consent information without being pressured. When medical language or a possible complication is confusing, the patient should request a clearer explanation. Patients may benefit from writing down information, attending with someone they trust, and reading the documents again at home.
Warning Signs After Cosmetic Surgery
Your surgical team should provide specific instructions about when and how to seek help. The surgical team should elective plastic surgery be contacted quickly if symptoms become worse, appear unusual, or do not match the expected healing process.
Potential emergency signs after cosmetic surgery include:
- Chest pain, shortness of breath, coughing blood, or fainting
- Sudden swelling, pain, redness, or warmth in one leg
- Significant bleeding or swelling that expands quickly
- Intense pain that does not improve after taking the recommended medicine
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Confusion, extreme weakness, or difficulty staying awake
- Skin that becomes very pale, dark, blistered, or cold to the touch
- Sudden vision loss, severe eye pain, or major visual changes
- Persistent vomiting that prevents normal hydration
- Any problem your surgeon specifically described as requiring emergency care
When a symptom could represent a life-threatening emergency, call 911 or go to an emergency department. Patients should seek immediate care rather than waiting for the surgeon's office when serious bleeding, breathing problems, chest pain, fainting, or another critical symptom occurs.
Cosmetic Surgery Costs and Canadian Health Coverage
Procedures performed only to change appearance are generally not covered by provincial or territorial health insurance. The patient is normally responsible for surgeon fees, anesthetic services, facility charges, implants, compression garments, medication, tests, and associated costs.
Before an operation, patients should ask who pays for treatment if a complication develops. Whether care is publicly covered can depend on the treatment needed, where it is delivered, and the rules of the patient's province or territory. Patients should budget for possible travel, lodging, caregiving, time away from employment, child care, and future revision surgery.
Patients considering medical tourism should think about who will provide follow-up care after returning to Canada. A lower initial price may not include management of infection, wound problems, blood clots, implant complications, or revision surgery.
Balancing the Benefits and Risks of Cosmetic Surgery
A sound decision about cosmetic surgery requires realistic expectations, appropriate health, informed consent, and knowledge of the healing process. A suitable patient recognizes that improvement is possible, but perfection is not.
Before deciding, compare what the operation may achieve with its physical, psychological, practical, and economic consequences. Think about your ability to obey postoperative instructions, live with scars, take enough time off, and emotionally manage an outcome that is not ideal.
A responsible surgeon may decline surgery if the patient's risk level is unacceptable, the likely improvement is minimal, or the desired result is unrealistic. This is an important part of responsible care.
Making an Informed Decision
Understanding the risks of cosmetic surgery does not mean assuming that complications will occur. Instead, risk awareness allows patients to decide using reliable facts rather than marketing, online trends, or cost as the only factor.
A safer decision involves understanding the procedure, identifying individual risk factors, checking the surgeon's qualifications, discussing concerns, and organizing postoperative care. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
