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. However, every operation involves some degree of uncertainty. Understanding the risks of cosmetic surgery is an essential 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.
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.
Minor side effects are expected after many procedures. During early recovery, swelling, bruising, tenderness, numbness, tightness, tiredness, and light drainage may be normal. A complication is different. 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
- Slow wound healing or separation of the incision
- Scars that become prominent, raised, wide, or uneven
- Damage to nerves, loss of feeling, or changes in sensation
- Skin, fat, or tissue loss caused by poor blood supply
- Reactions to anesthesia, medications, adhesives, or surgical materials
- Aesthetic concerns such as asymmetry, poor contours, or an unwanted result
- Changes in function, such as breathing, movement, or sensation
- 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 Short-Term Effects After 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.
Soreness After Cosmetic Surgery
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.
Postoperative Swelling and Bruising
Inflammation and the movement of fluid into surgical tissues cause swelling. The early result can remain difficult to assess until swelling subsides over the following weeks or months. Bruises form when tiny blood vessels are damaged and blood collects beneath the skin. Facial procedures, liposuction, breast surgery, and body contouring can all cause visible swelling and bruising.
The outcome of surgery should not be assessed before healing has progressed. Residual swelling can change shape, symmetry, and skin texture during recovery.
Changes in Feeling After Surgery
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. Feeling frequently returns as the nerves heal, although full recovery is not certain. In some cases, changes in sensation may be permanent.
Temporary Limits on Activity
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. Failing to follow activity restrictions may raise the risk of bleeding, swelling, wound breakdown, and other problems.
Surgical and Medical Complications
Postoperative Bleeding and Hematoma
A limited amount of bleeding around the incision may be expected. When bleeding is more substantial, blood may collect under the skin or in the surgical site and form a hematoma. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
Depending on its size and symptoms, a hematoma may be watched or medically drained. 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. Possible signs include increasing redness, warmth, swelling, pus-like drainage, worsening pain, fever, chills, or an unpleasant smell.
Treatment may involve antibiotics, wound care, drainage, or another operation. Removal can be required when infection develops around a breast implant or surgical device. Smoking, uncontrolled diabetes, poor nutrition, and problems with blood circulation can raise the risk of infection or make it harder to treat.
Postoperative Seroma
Clear fluid that gathers beneath the skin is known as a seroma. 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.
The body may gradually absorb a small seroma without further treatment. Larger ones may need to be drained, sometimes more than once. Untreated fluid can place pressure on the incision, affect healing, or become infected.
Deep Vein Thrombosis 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.
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.
Poor Wound Healing
An incision may heal slowly or begin to separate. 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. When a wound is left to close slowly from its deeper layers toward the surface, the process is called healing by secondary intention. This process can take longer and may leave a more visible scar.
Tissue Necrosis
Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and 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.
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.
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.
Anesthesia may be associated with the following risks:
- Nausea and vomiting
- Light-headedness, confusion, or extended sleepiness
- Throat discomfort or headache
- Unexpected reactions to anesthetic or other medications
- Abnormal blood pressure or irregular heart rhythm
- Problems with breathing
- Aspiration of stomach contents into the lungs
- Dental, lip, or airway damage
- Serious heart, lung, or neurological complications
A preoperative health history should include every medication, vitamin, supplement, cannabis product, alcohol or nicotine habit, allergy, previous anesthetic reaction, and relevant diagnosis. Withholding medical or lifestyle information may increase the risks of anesthesia and surgery.
Cosmetic Surgery Scars and Skin Changes
Any procedure that cuts the skin creates a scar. A surgeon may try to conceal incisions in folds, hair-bearing areas, or covered locations, but complete scar elimination is not possible.
During the first stages of healing, scars may look red, thick, firm, elevated, or darker than nearby skin. Scars may require a year or more to flatten, soften, and become less noticeable. 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 hypertrophic scar becomes thick or raised but stays within the original wound. 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. Scar treatment may improve texture and appearance, but it cannot ensure that a hypertrophic scar or keloid will never come back.
Changes in Skin Colour and Texture
Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. Alterations in colour or texture may improve, but they can also remain long term. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
The Risk of an Unwanted Cosmetic Result
Even when surgery is performed correctly, the final appearance may not match the patient's expectations. The body's response is shaped by age, anatomy, skin quality, earlier surgery, scar development, and normal side-to-side differences.
Possible aesthetic concerns include:
- Ongoing asymmetry
- Irregular or uneven body contours
- A result that is under-treated or over-treated
- An artificial-looking or over-tightened outcome
- Changes in shape as swelling settles
- Movement or poor positioning of an implant
- Scarring that is prominent or difficult to conceal
- Gradual recurrence of skin or tissue laxity
- Dissatisfaction despite an acceptable medical result
Before-and-after images, photographs, and computer simulations may help explain possibilities, but they do not promise a matching result. Every patient's tissues, proportions, and recovery process are unique.
The Possibility of Revision Surgery
A corrective operation may be discussed if a complication develops or if the original result could be refined. Revision surgery carries risks of its own. A second operation may be technically harder because previous surgery can leave scar tissue, stiffness, and diminished blood flow.
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.
Risks Associated With Specific Cosmetic Procedures
Although many operations share common complications, every cosmetic procedure has its own specific risks.
Possible Facelift and Neck Lift Complications
Facelift and neck lift complications may include hematoma, facial nerve injury, hairline changes, hair loss near incisions, skin loss, contour irregularities, earlobe distortion, numbness, facial weakness, and visible scarring. Because nicotine restricts circulation, its use can greatly increase wound and skin-healing complications.
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. It can take at least a year for swelling to resolve enough for the final nasal shape to be assessed. Revision rhinoplasty can be more difficult because of scar tissue and changes to the cartilage.
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. Severe eye pain or a sudden change in vision requires urgent medical assessment.
Breast Surgery Risks
Procedures such as breast augmentation, mastopexy, and breast reduction can change elective cosmetic plastic surgery nipple feeling, breast balance, scarring, and future breastfeeding ability. 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. Implants are not lifetime devices. Patients in Canada can review Health Canada information about uncommon implant-related conditions, such as breast implant-associated anaplastic large cell lymphoma.
Liposuction Risks
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. Removing larger volumes of fat or treating several body areas may increase medical stress and recovery demands.
Possible Tummy Tuck and Body Lift Complications
Large sections of skin and underlying tissue are moved during abdominoplasty and body lift surgery. 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 involves removing fat from one area and injecting it into another. The body naturally absorbs some transferred fat, potentially reducing volume or creating asymmetry. Additional complications include dead fat tissue, cysts, calcification, infection, oil cysts, and fat entering a blood vessel. Fat transfer risks vary according to whether the treatment area is the face, breast, buttocks, or another body region.
Factors That Increase the Risk of Complications
Certain medical conditions and lifestyle habits increase surgical risk. Before proceeding, some patients require tests, adjustments to treatment, weight changes, nicotine cessation, or approval from another medical professional.
Risk factors may include:
- Exposure to nicotine through smoking, vaping, gum, patches, or other products
- Poorly controlled diabetes
- Heart, lung, kidney, liver, or blood vessel disease
- A bleeding disorder or history of blood clots
- A high body mass index or significant changes in weight
- Sleep apnea
- Immune system disorders
- Poor nutrition or significant anemia
- Scar tissue or circulation changes from prior operations or radiation
- Medications or supplements that affect bleeding or healing
- Mental health concerns or unrealistic goals that interfere with informed decision-making
Having a risk factor does not always mean surgery is impossible. The surgeon needs to evaluate the level of risk and decide whether health or lifestyle changes are necessary before treatment.
Psychological Effects of Cosmetic Surgery
Cosmetic surgery can affect emotional health as well as physical health. Some patients feel anxious, impatient, or discouraged while swollen, bruised, tired, and unable to follow their normal routine. The term postoperative blues is sometimes used to describe this temporary decline in mood.
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.
A careful cosmetic surgery consultation should examine why the patient wants the procedure. Warning signs may include pressure from another person, repeated procedures without satisfaction, extreme focus on a minor feature, or the belief that one operation will completely transform a person's 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.
Reducing the Chance of Surgical Complications
Risk cannot be removed completely, but careful planning can make cosmetic surgery safer.
- Select a qualified doctor who has appropriate education and substantial experience performing the procedure.
- 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.
- Provide a complete medical history, including medications, supplements, nicotine, cannabis, alcohol, allergies, and prior operations.
- 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.
- Do not compare your healing speed with edited images or another patient's recovery.
- 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?
- Based on my health, goals, and anatomy, is this procedure suitable for me?
- What are the most common complications in your practice?
- Which uncommon but severe complications need to be considered?
- Who will provide anesthesia?
- How can I obtain care if a problem develops at night or on a weekend?
- Where would I receive emergency care if needed?
- What follow-up visits are included?
- Which additional expenses would I be responsible for if a complication or revision occurs?
Informed Consent for Cosmetic Surgery
Signing paperwork alone does not create true informed consent. The process requires clear communication so that the patient can make a knowledgeable and voluntary choice.
The consent process should cover the nature of the procedure, expected benefits, important risks, reasonable alternatives, recovery, limitations, and what could happen without treatment. The surgeon should also explain risks that may have particular importance because of the patient's occupation, health, daily activities, or individual goals.
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.
When to Seek Help After Cosmetic Surgery
Patients should receive clear directions about warning signs, emergency care, and after-hours communication. The surgical team should be contacted quickly if symptoms become worse, appear unusual, or do not match the expected healing process.
Urgent warning signs may include:
- Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness
- Unexpected pain, swelling, redness, or heat affecting one leg
- Uncontrolled bleeding or a sudden increase in swelling
- Intense pain that does not improve after taking the recommended medicine
- High fever, chills, spreading redness, or pus-like drainage
- Disorientation, marked weakness, or excessive drowsiness
- Possible tissue damage shown by abnormal colour, blistering, or low skin temperature
- Sudden vision loss, severe eye pain, or major visual changes
- Repeated vomiting or an inability to keep fluids down
- 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. Do not wait for an office to reopen when there is severe breathing trouble, chest pain, loss of consciousness, major bleeding, or another urgent concern.
Financial Considerations for Cosmetic Surgery in Canada
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.
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. Lower upfront fees may become more expensive if postoperative infection, wound breakdown, clotting, implant complications, or revision treatment is required.
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. Realistic patients seek meaningful improvement while accepting that no procedure can deliver a flawless result.
Patients should carefully weigh likely improvements against health risks, emotional effects, recovery demands, and financial costs. Consider whether you can follow the recovery plan, accept visible scars, manage time away from work, and cope with the possibility of an imperfect result.
When complications are too likely, benefits are small, or expectations cannot be met safely, an experienced surgeon may recommend against operating. Recommending against surgery can be a sign of careful and ethical medical practice.
Making an Informed Decision
Learning about cosmetic surgery risks does not mean expecting that something will go wrong. The goal is to make a careful choice based on medical information, not promotional claims, social media influence, or the lowest price.
Learn about the procedure, review your personal risk factors, confirm the surgeon's qualifications, ask detailed questions, and plan for a full recovery. When the benefits, limits, alternatives, and possible complications are understood, patients are better prepared to decide whether cosmetic surgery fits their needs.
