The shape, proportion, or overall appearance of the face and body can be improved through cosmetic surgery. For some people, it can also increase comfort with a physical feature that has caused distress 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.
Although most patients heal without serious problems, no surgeon can guarantee perfection or eliminate every surgical risk. Problems can occur because of anesthesia, bleeding, infection, poor healing, an unexpected reaction, or the way the body responds to surgery. Some problems resolve with simple treatment and do not cause lasting harm. Others may require medication, hospital care, revision surgery, or long-term follow-up.
Canadian patients should receive understandable information about benefits, material risks, available alternatives, recovery demands, and the possible effects of choosing no treatment. A thorough consultation should provide enough time to review the information and make a decision without pressure. 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?
Any undesirable medical, functional, or cosmetic result connected with an operation may be considered a cosmetic surgery risk. The procedure being performed, technique used, body area treated, duration of surgery, anesthesia method, and patient health all influence risk.
Minor side effects are expected after many procedures. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. Expected healing effects and surgical complications are different. It is an unexpected problem that exceeds routine healing and can require treatment.
Potential problems associated with plastic surgery include:
- A hematoma, which is a collection of blood, or other excessive bleeding
- An infection in the incision or deeper surgical tissues
- Seroma formation, which involves fluid collecting beneath the tissue
- Blood clots affecting the legs or lungs
- Delayed wound healing or wound separation
- Scars that become prominent, raised, wide, or uneven
- 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
- Unevenness, contour irregularities, or an unsatisfactory appearance
- Problems with normal function, including breathing, motion, or sensation
- Additional medical treatment or a revision operation
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
A degree of discomfort and physical change is expected while the body heals. Patients who understand expected recovery are better able to separate routine symptoms from possible complications.
Postoperative Pain and Tenderness
The amount of pain experienced depends on both the procedure and the individual. Patients may notice aching, tightness, burning, or tenderness around the treated area. Pain should usually become easier to manage as healing continues. Pain that suddenly becomes severe, spreads, or occurs with fever, redness, shortness of breath, or unusual swelling should be reported promptly.
Postoperative Swelling and Bruising
Swelling develops when inflammation allows fluid to collect in and around the treated area. For several weeks or even months, swelling may conceal the true result of surgery. Bruises form when tiny blood vessels are damaged and blood collects 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. 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 numbness, tingling, sensitivity, or reduced feeling is common after some operations. Feeling frequently returns as the nerves heal, although full recovery is not certain. In some cases, changes in sensation may be permanent.
Short-Term Activity Restrictions
Patients may need help with transportation, meals, child care, pet care, household work, and personal tasks. 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
Bleeding or Blood Collection
Minor bleeding near a surgical incision can occur during early recovery. 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.
Depending on its size and symptoms, a hematoma may be watched or medically drained. Some hematomas require another operation to control the bleeding and remove collected blood.
Surgical 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.
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. Patients who smoke or have uncontrolled diabetes, nutritional problems, or poor blood flow may face a higher infection risk and slower recovery.
Postoperative Seroma
Clear fluid that gathers beneath the skin is known as a seroma. Procedures such as abdominoplasty, body lift surgery, breast surgery, and large-area liposuction may have a greater seroma risk because they create space beneath the tissue.
The body may gradually absorb a small seroma without further treatment. Repeated drainage may be necessary when a significant seroma develops. If fluid is not treated, it may strain the incision, delay healing, or lead to infection.
Blood Clots and Pulmonary Embolism
Deep vein thrombosis, known as DVT, develops when a clot forms in one of the body's deep veins, usually in a leg. If part of the clot travels to the lungs, it can cause a pulmonary embolism. 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.
Problems With Incision Healing
An incision may heal slowly or begin to separate. Healing may be impaired by poor circulation, infection, pressure on the incision, nicotine, some medicines, or underlying health conditions.
Incision problems may need wound care, antibiotics, surgical cleaning, or further corrective surgery. Healing by secondary intention means allowing an open area to close gradually from the inside outward. This process can take longer and may leave a more visible scar.
Loss of Tissue From Poor Blood Supply
Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to die. Tissue loss may occur after procedures involving extensive lifting, tightening, or repositioning. Smoking and nicotine use are major preventable risk factors because nicotine narrows blood vessels and reduces oxygen delivery.
The extent of tissue damage determines which treatment is required. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery.
Risks Related to Anesthesia
Local anesthesia, sedation, general anesthesia, or a combination may be used during cosmetic surgery. The safest choice depends on the operation, the patient's medical history, the expected length of surgery, and the surgical setting.
Anesthesia may be associated with the following risks:
- Postoperative nausea or vomiting
- Light-headedness, confusion, or extended sleepiness
- Throat discomfort or headache
- An allergic response or adverse drug reaction
- Fluctuations in blood pressure or disturbances in heartbeat
- Breathing difficulties
- Aspiration, which occurs when material from the stomach reaches the lungs
- Damage to teeth, lips, or the airway
- 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.
Scarring and Changes to the Skin
Any procedure that cuts the skin creates a scar. Surgeons usually place incisions where they can be hidden within natural folds, hairlines, or clothing, but a scar cannot be erased completely.
Scars often appear red, raised, firm, or darker during early healing. 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.
Changes in Skin Colour and Texture
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.
Cosmetic Outcome Risks and Patient Dissatisfaction
A procedure can be medically and technically successful while still producing a result the patient did not anticipate. Individual anatomy, skin flexibility, age, past procedures, scarring, and natural asymmetry all affect healing.
Appearance-related problems may include:
- Persistent asymmetry
- Visible dents, bulges, or contour differences
- Under-correction or over-correction
- A result that appears unnatural or excessively tight
- Alterations in shape while swelling resolves
- An implant that shifts, rotates, or sits incorrectly
- Scarring that is prominent or difficult to conceal
- Gradual recurrence of skin or tissue laxity
- 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. Every patient's tissues, proportions, and recovery process are unique.
Corrective and Revision Surgery
A corrective operation may be discussed if a complication develops or if the original result could be refined. 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.
Risks Associated With Specific Cosmetic Procedures
General surgical risks apply to many operations, but each procedure also has unique concerns.
Facelift and Neck Lift Risks
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. Smoking, vaping, and other nicotine exposure can significantly raise the chance of skin loss and delayed healing.
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. 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.
Possible Complications of Eyelid Surgery
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. 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. 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 publishes safety guidance concerning rare illnesses associated with some 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. 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
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. Seroma, blood clots, infection, necrosis, delayed wound healing, numbness, noticeable scars, and altered belly button position may occur. 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. Some of the transferred fat will be absorbed, which can affect volume and symmetry. Other risks include fat necrosis, cysts, calcification, infection, oil cysts, and accidental injection into a blood vessel. The location where fat is injected, such as the face, breasts, or buttocks, affects the cosmetic transformation type and seriousness of potential complications.
Who Has a Higher Risk of Complications?
A patient's health status and daily habits may make complications more likely. Preoperative preparation may include laboratory testing, medication changes, weight management, stopping nicotine, or obtaining medical clearance.
Risk factors may include:
- Cigarette smoking, vaping, or any form of nicotine use
- Diabetes with unstable or elevated blood sugar
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A bleeding disorder or history of blood clots
- Obesity or major weight changes
- A diagnosed or suspected sleep-related breathing disorder
- Immune disorders or reduced immune function
- Inadequate nutrition or serious anemia
- Earlier surgery or radiation therapy involving the same area
- Drugs, vitamins, or supplements that interfere with clotting or tissue repair
- Expectations that cannot be achieved or unaddressed psychological concerns affecting consent
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
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. The term postoperative blues is sometimes used to describe this temporary decline in mood.
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. Surgery may not relieve the underlying concern. 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.
- Select a qualified doctor who has appropriate education and substantial experience performing the procedure.
- Verify the physician's registration and standing through the medical regulatory authority in your province or territory.
- Discuss the surgical location, its safety procedures, infection-control practices, and ability to handle emergencies.
- Give the surgical team accurate information about diagnoses, operations, prescriptions, supplements, substances, and allergies.
- Carefully follow all directions related to eating, drinking, preoperative tests, medication adjustments, and nicotine cessation.
- Plan for a trusted adult to take you home and help with daily needs after surgery.
- Do not schedule travel, work duties, exercise, or major events until you understand how long recovery may take.
- Go to every scheduled postoperative visit and quickly contact the surgical team about unexpected symptoms.
- 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
Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. Patients may verify a physician's licence and registered specialty through the online register maintained by their provincial or territorial regulator.
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 are your surgical qualifications and specialty credentials?
- How frequently is this specific procedure performed in your practice?
- Am I a suitable candidate based on my health and anatomy?
- What complications are seen most frequently with this procedure in your practice?
- What low-frequency, high-impact risks should I know about?
- Which medical professional will administer and monitor my anesthesia?
- What happens if I have a complication after business hours?
- Which hospital or emergency facility would treat me if a serious problem occurred?
- How many postoperative appointments are provided as part of the surgical plan?
- What costs could arise if I need treatment or revision surgery?
Informed Consent for Cosmetic Surgery
Informed consent is more than signing a form. 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. 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. Questions should be asked whenever risks, terminology, or instructions are not fully understood. Taking notes, involving a support person, and reviewing written material outside the clinic can support an informed decision.
Warning Signs After Cosmetic Surgery
Your surgical team should provide specific instructions about when and how to seek help. The surgical team should be contacted quickly if symptoms become worse, appear unusual, or do not match the expected healing process.
Symptoms that may require urgent care 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
- Pain that remains severe despite the prescribed treatment plan
- A significant fever, shaking chills, expanding redness, or thick discharge
- Mental confusion, severe weakness, or unusual inability to remain alert
- 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
- A symptom listed as urgent in the postoperative instructions
Call 911 or seek emergency care when symptoms may be life-threatening. Severe breathing difficulty, chest pain, unconsciousness, heavy bleeding, and other emergency symptoms should not wait until normal clinic hours.
Financial Risks and Health Coverage in Canada
Procedures performed only to change appearance are generally not covered by provincial or territorial health insurance. Out-of-pocket expenses may include the surgeon, anesthesia provider, operating room, medical devices, recovery clothing, prescriptions, laboratory work, and follow-up items.
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. Travel, accommodation, nursing assistance, missed work, child care, and revision surgery can create additional expenses.
Medical tourists need to determine which Canadian provider, if any, will manage recovery and complications after their return. Lower upfront fees may become more expensive if postoperative infection, wound breakdown, clotting, implant complications, or revision treatment is required.
Weighing Cosmetic Surgery Benefits Against Risks
The decision to have cosmetic surgery should be based on realistic goals, good health, informed consent, and a clear understanding of recovery. A suitable patient recognizes that improvement is possible, but perfection is not.
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. 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. It means making a thoughtful decision based on accurate information rather than advertising, social media trends, or price alone.
Before surgery, research the operation, assess your health risks, verify medical credentials, ask thorough questions, and prepare for the complete healing period. When the benefits, limits, alternatives, and possible complications are understood, patients are better prepared to decide whether cosmetic surgery fits their needs.
