Cosmetic surgery can improve 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. A careful decision about cosmetic surgery should include a clear understanding of its possible risks.
A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. 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.
Canadian patients should receive understandable information about benefits, material risks, available alternatives, recovery demands, and the possible effects of choosing no treatment. During a careful consultation, patients should be able to consider the facts without being rushed. Cosmetic surgery is usually elective, so you should feel comfortable delaying or declining it when the risks outweigh the likely 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. Swelling, bruising, soreness, numbness, tightness, fatigue, and mild drainage may be normal during early healing. A true complication is not the same as an expected side effect. A complication extends beyond normal recovery and may need medical care.
Potential problems associated with plastic surgery include:
- Bleeding or a collection of blood called a hematoma
- Incision-site or deep-tissue infection
- Fluid buildup, known as a seroma
- Blood clots in the legs or lungs
- Delayed wound healing or wound separation
- Visible scarring that may be thick, widened, raised, or irregular
- Nerve-related problems, including numbness or unusual sensation
- Skin, fat, or tissue loss caused by poor blood supply
- Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products
- Asymmetry, contour problems, or an unwanted appearance
- Functional changes affecting breathing, movement, or feeling
- A need for further care or corrective surgery
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.
Expected Short-Term Effects of Cosmetic Surgery
Normal recovery often includes temporary discomfort and changes in appearance or sensation. Patients who understand expected recovery are better able to separate routine symptoms from possible complications.
Pain and Tenderness
Pain levels vary by procedure and patient. Tightness, aching, burning, or tenderness may occur near the surgical area. Discomfort is normally expected to improve gradually during healing. Patients should quickly report severe or spreading pain, especially when it is accompanied by fever, redness, shortness of breath, or unusual swelling.
Bruising and Tissue Swelling
Inflammation and the movement of fluid into surgical tissues cause swelling. For several weeks or even months, swelling may conceal the true result of surgery. Bruising occurs when small blood vessels leak beneath the skin. Patients undergoing face surgery, breast surgery, liposuction, or body contouring may experience noticeable bruising and swelling.
Patients are advised to avoid making early judgments about their final appearance. Remaining swelling may temporarily affect shape, balance, and the texture of the skin.
Altered Sensation and Numbness
Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. 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. Permanent sensory changes are possible.
Short-Term Activity Restrictions
Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. Restrictions may apply to driving, physical activity, lifting, swimming, and work. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Potential Surgical Complications
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. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
A small hematoma may only need monitoring, but a larger one may require drainage. A return to the operating room may be necessary in more serious cases.
Infection
An infection can develop in the skin, incision, tissue, or around an implant. An infection may cause increasing warmth, redness, swelling, pain, discharge resembling pus, fever, chills, or a bad smell.
Antibiotics, specialized wound care, drainage, or further surgery may be needed to treat an infection. If a breast implant or another implanted device becomes infected, removal may be necessary. Infection risk and treatment difficulty may increase with smoking, poorly controlled diabetes, inadequate nutrition, or reduced circulation.
Postoperative 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.
Small seromas may resolve as the body absorbs the fluid. A larger seroma may require drainage on one or several occasions. Untreated fluid can place pressure on the incision, affect healing, or become infected.
Blood Clot Complications
A blood clot that forms in a deep vein, commonly within the leg, is called deep vein thrombosis, or DVT. A pulmonary embolism can occur if a piece of the clot breaks away and reaches the lungs. A pulmonary embolism requires emergency medical care.
Factors that may raise blood clot risk include lengthy surgery, reduced mobility, a history of clots, particular medications, nicotine exposure, obesity, certain illnesses, and multiple procedures performed together. Depending on the patient, preventive steps may involve getting up early, using compression equipment or garments, staying hydrated, or taking prescribed blood thinners.
Delayed or Difficult Wound Healing
A surgical wound may take longer than expected to close or may start to open. Healing may be impaired by poor circulation, infection, pressure on the incision, nicotine, some medicines, or underlying health conditions.
Treatment for a wound complication can include specialized dressings, antibiotic medication, removal of unhealthy tissue, or another operation. When a wound is left to close slowly from its deeper layers toward the surface, the process is called healing by secondary intention. The recovery period may be extended, and the final scar may be more prominent.
Skin or Tissue Necrosis
Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to die. This complication can occur after procedures that lift, tighten, or reposition large sections of tissue. Nicotine exposure is an important avoidable risk because it constricts blood vessels and limits oxygen reaching the tissues.
Management of necrosis varies according to the size and depth of the affected area. 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
Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. The most suitable anesthesia plan is based on the type of surgery, patient health history, procedure duration, and location where surgery takes place.
Possible anesthesia-related problems include:
- Nausea and vomiting
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- Throat discomfort or headache
- Allergic or medication reactions
- Abnormal blood pressure or irregular heart rhythm
- Problems with breathing
- 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. Leaving out information can make anesthesia and surgery less safe.
Cosmetic Surgery Scars and Skin Changes
A surgical procedure that breaks the skin will always leave some degree of scarring. A surgeon may try to conceal incisions in folds, hair-bearing areas, or covered locations, but complete scar elimination is not possible.
Early scars can be firm, raised, reddish, or more deeply coloured before they mature. They may soften and fade over 12 months or longer. How a scar eventually looks is affected by heredity, skin type, wound tension, infection, ultraviolet exposure, aftercare, incision placement, and the operation performed.
Raised Scars and Keloid Formation
A hypertrophic scar becomes thick or raised but stays within the original wound. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. 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. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return.
Skin Colour and Texture Changes
Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin texture. Alterations in colour or texture may improve, but they can also remain long term. 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. Healing is affected by anatomy, skin elasticity, age, previous surgery, scar formation, and natural differences between the two sides of the body.
Appearance-related problems may include:
- Ongoing asymmetry
- Uneven contours or visible irregularities
- Under-correction or over-correction
- A result that appears unnatural or excessively tight
- Alterations in shape while swelling resolves
- Implant position problems
- Noticeable scars or scars in an unfavourable location
- Recurrence of sagging or tissue laxity over time
- Patient dissatisfaction even when the result is medically acceptable
Visual examples and digital imaging can guide consultation discussions, although no patient can be guaranteed the same outcome. Each patient has different anatomy and heals in a different way.
Revision Cosmetic Surgery
A corrective operation may be discussed if a complication develops or if the original result could be refined. A second procedure introduces another set of surgical 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.
It is important to ask how the practice handles revisions and which expenses are covered. Additional costs for the surgeon, operating room, anesthetic, implants, medicine, transportation, accommodation, and missed employment may fall outside the initial price.
Procedure-Specific Cosmetic Surgery Risks
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.
Possible Rhinoplasty Complications
After nose surgery, patients may experience persistent swelling, nosebleeds, infection, asymmetry, smell changes, irregular contours, septal perforation, collapse of nasal support, or obstructed breathing. A rhinoplasty result may not fully settle for 12 months or more. A revision nose operation is often more challenging because the first surgery changes the cartilage and creates internal scarring.
Eyelid Surgery 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. A patient should seek urgent care if severe eye pain or an abrupt change in vision occurs.
Possible Breast Procedure Complications
Breast augmentation, breast lift, and breast reduction may affect nipple sensation, breast symmetry, scar appearance, and the ability to breastfeed. Hematoma, infection, fat necrosis, poor healing, and altered nipple or areola position are also possible.
Breast implants bring added long-term considerations. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. Breast implants are not designed to last for an entire lifetime. Patients in Canada can review Health Canada information about uncommon implant-related conditions, such as breast implant-associated anaplastic large cell lymphoma.
Risks of Liposuction
Liposuction complications may include contour irregularities, dents, rippling, loose skin, fluid imbalance, numbness, seroma, infection, internal injury, fat embolism, and lidocaine toxicity when local anesthetic is used. High-volume liposuction and treatment of several regions can place greater stress on the body and make recovery more demanding.
Possible Tummy Tuck and Body Lift Complications
Large sections of skin and underlying tissue are moved during abdominoplasty and body lift surgery. Seroma, blood clots, infection, necrosis, delayed wound healing, numbness, noticeable scars, and altered belly button position may occur. Patients may need several weeks of movement restrictions.
Risks of Fat Transfer
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. Fat grafting may also cause fat necrosis, cyst formation, calcium deposits, infection, oily fluid collections, or unintended injection into circulation. The location where fat is injected, such as the face, breasts, or buttocks, affects the type and seriousness of potential complications.
Who Has a Higher Risk of Complications?
Some health and lifestyle factors can raise the chance of complications. Preoperative preparation may include laboratory testing, medication changes, weight management, stopping nicotine, or obtaining medical clearance.
Risk factors may include:
- Smoking, vaping, or using nicotine products
- Poorly controlled diabetes
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A bleeding disorder or history of blood clots
- Obesity, unstable weight, or recent major weight loss or gain
- A diagnosed or suspected sleep-related breathing disorder
- Conditions affecting the immune system
- Inadequate nutrition or serious anemia
- Earlier surgery or radiation therapy involving the same area
- Medications or supplements that affect bleeding or healing
- Expectations that cannot be achieved or unaddressed psychological concerns affecting consent
A higher-risk medical history does not necessarily make an operation unsuitable. The surgeon needs to evaluate the level of risk and decide whether health or lifestyle changes are necessary before treatment.
Emotional and Mental Health Considerations
Cosmetic surgery can affect emotional health as well as physical health. During recovery, patients can become anxious or discouraged aesthetic surgery because they look swollen, feel tired, and cannot resume normal activities. The term postoperative blues is sometimes used to describe this temporary decline in mood.
Significant dissatisfaction is more likely when the expected transformation is not medically achievable. Although surgery can alter appearance, it cannot promise self-confidence, fix relationships, ensure professional success, or resolve wider life difficulties.
A careful cosmetic surgery consultation should examine why the patient wants the procedure. Concerns may arise when someone is being pressured, remains unhappy after repeated procedures, is intensely focused on a small flaw, or expects surgery to change every part of life.
Body dysmorphic disorder causes significant distress and preoccupation with appearance flaws that may seem minor or unnoticeable to others. An operation may fail to resolve the deeper psychological distress. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation.
How to Reduce the Risks of Cosmetic Surgery
Cosmetic surgery always carries some risk, yet careful planning can reduce the likelihood of complications.
- Choose a properly qualified physician with training and experience relevant to the procedure.
- Confirm through your province or territory's college of physicians and surgeons that the doctor is licensed and in good standing.
- Ask where the procedure will be performed and what safety, emergency, and infection-control systems are available.
- 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.
- When needed, organize transportation and early postoperative support from a responsible adult.
- Understand the recovery timeline before booking work, travel, exercise, or major events.
- Attend all follow-up appointments and report unusual symptoms promptly.
- Avoid judging your recovery against filtered photographs or the healing experience of someone else.
- Allow swelling and scar tissue to settle fully before considering corrective surgery.
Choosing a Cosmetic Surgeon in Canada
Medical regulation in Canada is handled at the provincial and territorial level. The public directory of the appropriate college of physicians and surgeons can be used to check licensing, specialty registration, and listed practice details.
Another useful question is whether the doctor holds plastic surgery certification from the Royal College of Physicians and Surgeons of Canada. Royal College certification is valuable, but it should be considered alongside relevant experience, patient communication, emergency planning, surgical environment, and postoperative support.
Questions to ask during a cosmetic surgery consultation include:
- What are your surgical qualifications and specialty credentials?
- How many times have you carried out this operation?
- Am I a suitable candidate based on my health and anatomy?
- What complications are seen most frequently with this procedure in your practice?
- Which uncommon but severe complications need to be considered?
- Who is responsible for anesthesia care during the operation?
- How can I obtain care if a problem develops at night or on a weekend?
- Where would I receive emergency care if needed?
- How many postoperative appointments are provided as part of the surgical plan?
- What costs could arise if I need treatment or revision surgery?
Understanding Informed Consent
Signing paperwork alone does not create true informed consent. It is an ongoing discussion that should give the patient enough information to make a voluntary decision.
Patients should be informed about how the operation works, its likely benefits, material risks, alternatives, healing process, limits, and the possible consequences of no surgery. Risks that are especially relevant to the patient's health, job, lifestyle, or personal priorities should also be discussed.
A patient should never feel rushed to sign. When medical language or a possible complication is confusing, the patient should request a clearer explanation. It can be helpful to take notes, bring a trusted person to the consultation, and review written instructions at home.
When to Seek Help After Cosmetic Surgery
Patients should receive clear directions about warning signs, emergency care, and after-hours communication. Unexpected or worsening symptoms that fall outside the recovery instructions should be reported without delay.
Potential emergency signs after cosmetic surgery include:
- Breathing problems, chest discomfort, bloody coughing, or fainting
- One-sided leg swelling, tenderness, warmth, or discolouration
- Heavy bleeding or rapidly increasing swelling
- Severe pain that is not controlled by prescribed medication
- A significant fever, shaking chills, expanding redness, or thick discharge
- 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
- Ongoing vomiting or difficulty drinking without becoming sick
- Any problem your surgeon specifically described as requiring emergency care
Call 911 or seek emergency care when symptoms may be life-threatening. 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.
Financial Considerations for Cosmetic Surgery in Canada
Canadian provincial and territorial health plans generally do not pay for operations performed solely for cosmetic reasons. Patients usually pay for the surgeon, anesthesia, operating facility, implants, garments, prescriptions, testing, and other related expenses.
The financial responsibility for postoperative problems should be clarified in advance. Coverage may depend on the medical service required, the location where treatment is provided, and the patient's provincial or territorial plan. Extra costs may arise from transportation, hotels, private nursing, lost income, family care, and corrective procedures.
Patients considering medical tourism should think about who will provide follow-up care after returning to Canada. An inexpensive overseas package may exclude the cost of treating infection, poor healing, DVT, implant problems, and corrective operations.
Balancing the Benefits and Risks of Cosmetic Surgery
The decision to have cosmetic surgery should be based on realistic goals, good health, informed consent, and a clear understanding of recovery. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection.
Take time to compare the expected benefit with the medical, emotional, practical, and financial risks. 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. A decision not to operate is sometimes the safest and most responsible form of patient care.
Making an Informed Decision
Understanding the risks of cosmetic surgery does not mean assuming that complications will occur. The goal is to make a careful choice based on medical information, not promotional claims, social media influence, or the lowest price.
Before surgery, research the operation, assess your health risks, verify medical credentials, ask thorough questions, and prepare for the complete healing period. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
