Cosmetic surgery can enhance the shape, proportion, or appearance of the face and body. It may also help a person feel more comfortable with a feature that has bothered them for years. 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.
Most patients recover without a major complication, but no surgeon can promise a perfect result or a risk-free operation. Complications may result from anesthesia, bleeding, infection, delayed healing, unexpected reactions, or an individual response to surgery. 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. Most cosmetic procedures are optional, which means you can delay or decline surgery when its risks do not justify its likely benefits.
What Are the Risks of Cosmetic Surgery?
The risks of cosmetic surgery include unwanted outcomes that affect health, physical function, or appearance. 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 minor 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. It is an unexpected problem that exceeds routine healing and can require treatment.
Possible complications of plastic surgery include:
- Bleeding or the development of a blood collection known as a hematoma
- An infection in the incision or deeper surgical tissues
- A collection of fluid called 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
- Damage to nerves, loss of feeling, or changes in sensation
- Tissue damage or loss resulting from inadequate blood flow
- Reactions to anesthesia, medications, adhesives, or surgical materials
- Asymmetry, contour problems, or an unwanted appearance
- Functional changes affecting breathing, movement, or feeling
- The need for additional treatment or revision surgery
Major complications do not happen often, but patients should understand that they remain possible. Possible rare complications include severe infection, major hemorrhage, organ damage, heart problems, stroke, a blood clot in the lungs, permanent impairment, and death.
Common Early Effects During Cosmetic Surgery Recovery
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.
Postoperative Pain and Tenderness
Each patient experiences pain differently, and some operations cause more discomfort than others. 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
Swelling is caused by inflammation and fluid moving into the treated tissues. It may hide the initial surgical result for weeks or months. Bruising occurs when small blood vessels leak beneath the skin. Visible bruising and swelling may follow facial surgery, liposuction, breast procedures, or body contouring.
Patients should not judge the final result too early. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Altered Sensation and Numbness
Small sensory nerves may be stretched, moved, or cut during surgery. Temporary changes such as tingling, numbness, tenderness, or reduced sensation may occur after surgery. Nerve recovery often improves sensation over time, but normal feeling may not return completely. Permanent sensory changes are possible.
Activity Limitations During Recovery
During early recovery, patients may require support with transportation, meals, family duties, pets, household chores, and self-care. Restrictions may apply to driving, physical activity, lifting, swimming, and work. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Surgical and Medical Complications
Bleeding or Blood Collection
A small amount of bleeding may occur around an incision. More significant bleeding can form a hematoma, which is a collection of blood beneath the skin or inside the surgical area. Increasing tenderness, firmness, swelling, discolouration, or an abrupt difference between two sides may indicate a hematoma.
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.
Surgical Infection
The incision, nearby skin, deeper surgical tissues, or an implant pocket can become infected. An infection may cause increasing warmth, redness, swelling, pain, discharge resembling pus, fever, chills, or a bad smell.
An infection can require medication, incision care, removal of fluid, or an additional procedure. If a breast implant or another implanted device becomes infected, removal may be necessary. Patients who smoke or have uncontrolled diabetes, nutritional problems, or poor blood flow may face a higher infection risk and slower recovery.
Postoperative Seroma
A seroma is a pocket of clear fluid that collects under the skin. It is more common after procedures that create a large space beneath the tissue, such as tummy tuck surgery, body lift surgery, breast surgery, or extensive liposuction.
The body may gradually absorb a small seroma without further treatment. A larger seroma may require drainage on one or several occasions. If fluid is not treated, it may strain the incision, delay healing, or lead to infection.
Blood Clots and Pulmonary Embolism
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. This complication can be life-threatening and must be treated urgently.
Long procedures, natural looking cosmetic surgery inactivity, earlier blood clots, some drugs, nicotine use, excess body weight, health conditions, and combined operations can increase the chance of DVT or pulmonary embolism. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate.
Problems With Incision Healing
A surgical wound may take longer than expected to close or may start to open. Factors such as reduced blood flow, infection, wound tension, nicotine use, medications, and illness may prevent normal healing.
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.
Tissue Necrosis
Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and 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. It may involve wound care, removal of damaged tissue, skin grafting, reconstructive surgery, or a delayed revision.
Risks Related to Anesthesia
Local anesthesia, sedation, general anesthesia, or a combination may be used during cosmetic surgery. The most suitable anesthesia plan is based on the type of surgery, patient health history, procedure duration, and location where surgery takes place.
Potential complications connected with anesthesia include:
- Postoperative nausea or vomiting
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- Headache or sore throat
- Allergic or medication reactions
- Abnormal blood pressure or irregular heart rhythm
- Respiratory difficulty
- Stomach contents entering the lungs, known as aspiration
- Dental, lip, or airway damage
- Serious heart, lung, or neurological complications
Before surgery, patients should disclose all prescription drugs, over-the-counter medications, vitamins, supplements, cannabis products, alcohol use, nicotine use, allergies, past anesthesia reactions, and relevant medical conditions. The safety of the operation can be reduced when important health information is omitted.
Scarring and Changes to the Skin
A surgical procedure that breaks the skin will always leave some degree of scarring. Incisions are often positioned in natural creases, along hairlines, or beneath clothing, although no scar can be removed entirely.
During the first stages of healing, scars may look red, thick, firm, elevated, or darker than nearby skin. Over 12 months or longer, scar tissue can gradually fade and soften. The final appearance depends on genetics, skin type, incision tension, infection, sun exposure, wound care, location, and the type of operation.
Raised Scars and Keloid Formation
A scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. 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. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return.
Skin Colour and Texture Changes
Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. These effects may be temporary or permanent. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
The Risk of an Unwanted Cosmetic Result
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.
Possible aesthetic concerns include:
- Persistent asymmetry
- Visible dents, bulges, or contour differences
- Under-correction or over-correction
- An artificial-looking or over-tightened outcome
- Alterations in shape while swelling resolves
- Implant position problems
- Visible or poorly placed scars
- A return of looseness or sagging with age and time
- Patient dissatisfaction even when the result is medically acceptable
Before-and-after images, photographs, and computer simulations may help explain possibilities, but they do not promise a matching result. Anatomy and healing responses vary from one person to another.
Corrective and Revision 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.
Before proceeding, patients should understand exactly what is included in the surgeon's or clinic's revision policy. Additional costs for the surgeon, operating room, anesthetic, implants, medicine, transportation, accommodation, and missed employment may fall outside the initial price.
Complications by Type of Cosmetic Surgery
General surgical risks apply to many operations, but each procedure also has unique concerns.
Risks of Facelift and Neck Lift Surgery
Hematoma, facial nerve injury, hairline alteration, hair loss around incisions, skin necrosis, contour problems, earlobe changes, loss of feeling, facial weakness, and visible scarring are among the risks of facelift and neck lift surgery. Because nicotine restricts circulation, its use can greatly increase wound and skin-healing complications.
Possible Rhinoplasty Complications
Rhinoplasty may cause ongoing swelling, nosebleeds, infection, asymmetry, changes in smell, visible contour irregularities, septal perforation, nasal collapse, or difficulty breathing through the nose. The final shape may take a year or longer to become clear. A revision nose operation is often more challenging because the first surgery changes the cartilage and creates internal scarring.
Blepharoplasty Risks
Possible eyelid surgery complications include eye dryness, irritation, short-term blurred vision, incomplete eyelid closure, abnormal lid position, unevenness, scars, bleeding behind the eye, and visual changes. Immediate medical evaluation is needed for intense eye pain or a sudden visual disturbance.
Risks of Cosmetic Breast Surgery
Breast augmentation, breast lift, and breast reduction may affect nipple sensation, breast symmetry, scar appearance, and the ability to breastfeed. Other risks include hematoma, infection, fat necrosis, delayed healing, and changes in nipple or areola position.
Patients with breast implants face additional concerns that can develop over time. These include capsular contracture, implant rupture, deflation, rippling, movement, rotation, pain, and the need for future monitoring or surgery. 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.
Risks of Liposuction
Possible problems after liposuction include uneven contours, indentations, rippled or loose skin, changes in fluid balance, reduced feeling, seroma, infection, internal damage, fat embolism, and toxicity from lidocaine. High-volume liposuction and treatment of several regions can place greater stress on the body and make recovery more demanding.
Risks of Abdominoplasty and Body Lift Surgery
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. Risks include seroma, blood clots, infection, skin loss, wound separation, numbness, prominent scarring, and changes to the position or shape of the belly button. Activity and lifting restrictions can remain in place for a number of weeks.
Fat Grafting Risks
Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. Because a portion of the injected fat may not survive, the final fullness and balance can change. Additional complications include dead fat tissue, cysts, calcification, infection, oil cysts, and fat entering a blood vessel. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area.
Who Has a Higher Risk of Complications?
Certain medical conditions and lifestyle habits increase surgical risk. Preoperative preparation may include laboratory testing, medication changes, weight management, stopping nicotine, or obtaining medical clearance.
The likelihood of complications may increase with:
- Exposure to nicotine through smoking, vaping, gum, patches, or other products
- Diabetes that is not well controlled
- Cardiac, respiratory, renal, liver, or vascular conditions
- Past DVT, pulmonary embolism, or a diagnosed bleeding disorder
- Obesity or major weight changes
- Sleep apnea
- Immune disorders or reduced immune function
- Nutritional deficiencies or a low red blood cell count
- Earlier surgery or radiation therapy involving the same area
- Prescription products, non-prescription medicines, or supplements that alter bleeding and healing
- Unrealistic expectations or untreated mental health concerns that affect decision-making
A higher-risk medical history does not necessarily make an operation unsuitable. It means the surgeon must decide whether the procedure can be performed safely and whether changes are needed before proceeding.
Psychological and Emotional Risks
An operation performed for appearance can influence a patient's mental and emotional state in addition to the body. During recovery, patients can become anxious or discouraged because they look swollen, feel tired, and cannot resume normal activities. This temporary low mood is sometimes called postoperative blues.
When a patient's expectations exceed the realistic limits of surgery, deeper or longer-lasting disappointment may follow. Cosmetic surgery may change a physical feature, but it cannot guarantee confidence, repair a relationship, create career success, or solve broader personal problems.
A responsible assessment should explore the patient's reasons for seeking surgery. Possible warning signs include outside pressure, ongoing dissatisfaction despite multiple operations, severe concern about a minor feature, and unrealistic beliefs about total life transformation.
Body dysmorphic disorder causes significant distress and preoccupation with appearance flaws that may seem minor or unnoticeable to others. Changing the physical feature does not necessarily treat the underlying mental health condition. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation.
Ways to Lower Cosmetic Surgery Risks
Although no operation can be made completely risk-free, thorough preparation can improve safety.
- 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.
- Provide a complete medical history, including medications, supplements, nicotine, cannabis, alcohol, allergies, and prior operations.
- Complete required testing and obey instructions about fasting, medicines, supplements, smoking, vaping, and other nicotine products.
- Arrange a responsible adult to drive you home and assist during early recovery when required.
- Do not schedule travel, work duties, exercise, or major events until you understand how long recovery may take.
- 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.
How to Select a Cosmetic Surgeon in Canada
In Canada, physicians are licensed and regulated by provincial and territorial authorities. 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. Royal College certification is valuable, but it should be considered alongside relevant experience, patient communication, emergency planning, surgical environment, and postoperative support.
During the consultation, patients may wish to ask:
- What professional education and certifications have you completed?
- How often do you perform this procedure?
- Does my medical history and physical anatomy make me an appropriate candidate?
- What complications are seen most frequently with this procedure in your practice?
- Which uncommon but severe complications need to be considered?
- Which medical professional will administer and monitor my anesthesia?
- Who should I contact if I experience a complication outside normal clinic hours?
- Where would I receive emergency care if needed?
- Which follow-up visits and services are included in the fee?
- What costs could arise if I need treatment or revision surgery?
What Informed Consent Should Include
Informed consent is more than signing a form. The process requires clear communication so that the patient can make a knowledgeable and voluntary choice.
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. Any complication that could significantly affect the patient's medical condition, employment, lifestyle, or priorities should receive special attention.
No one should be pushed into signing a surgical consent form quickly. 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.
Postoperative Warning Signs
The surgeon's office should explain which symptoms require attention and copyright the appropriate provider. Contact the clinic promptly when symptoms are unexpected, worsening, or different from the recovery plan.
Symptoms that may require urgent care include:
- Breathing problems, chest discomfort, bloody coughing, or fainting
- One-sided leg swelling, tenderness, warmth, or discolouration
- Heavy bleeding or rapidly increasing swelling
- Intense pain that does not improve after taking the recommended medicine
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Disorientation, marked weakness, or excessive drowsiness
- A pale, dark, blistered, or unusually cold area of skin
- Sudden vision loss, severe eye pain, or major visual changes
- Persistent vomiting that prevents normal hydration
- Any symptom the surgical team identified as an emergency
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.
Cosmetic Surgery Costs and Canadian Health Coverage
When a procedure is intended only to improve appearance, public health insurance in Canada will usually not cover it. The patient is normally responsible for surgeon fees, anesthetic services, facility charges, implants, compression garments, medication, tests, and associated costs.
The financial responsibility for postoperative problems should be clarified in advance. 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. Extra costs may arise from transportation, hotels, private nursing, lost income, family care, and corrective procedures.
Anyone travelling outside Canada for cosmetic surgery should arrange appropriate postoperative care before coming home. A lower initial price may not include management of infection, wound problems, blood clots, implant complications, or revision surgery.
Evaluating the Advantages and Risks of Cosmetic Surgery
Patients should consider surgery only when their goals are achievable, their health is suitable, and they understand the risks and recovery. 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. The decision should account for recovery restrictions, permanent scarring, employment absence, and the possibility that the final result may fall short of expectations.
A qualified surgeon may advise against a procedure when the risk is too high, the expected benefit is limited, or the patient's goals cannot be achieved safely. Recommending against surgery can be a sign of careful and ethical medical practice.
Deciding Whether Cosmetic Surgery Is Right for You
Being aware of possible complications is not the same as believing they are certain to happen. 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.
