Through cosmetic surgery, patients may change the shape, proportions, or appearance of their face or 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. 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. 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. A thorough consultation should provide enough time to review the information and make a decision without pressure. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits.
What Are the Risks of Cosmetic Surgery?
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.
It is normal for patients to experience some minor effects after many operations. During early recovery, swelling, bruising, tenderness, numbness, tightness, tiredness, and light drainage may be normal. 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
- Incision-site or deep-tissue infection
- A collection of fluid called a seroma
- Clots that form in a leg vein or travel to the lungs
- Delayed wound healing or wound separation
- Noticeable, raised, widened, or uneven scars
- Nerve injury, numbness, or altered sensation
- Tissue damage or loss resulting from inadequate blood flow
- Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products
- Aesthetic concerns such as asymmetry, poor contours, or an unwanted result
- Problems with normal function, including breathing, motion, or sensation
- A need for further care or corrective surgery
Although serious complications are rare, they must still be reviewed before surgery. 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
Some discomfort and physical change are part of normal healing. Knowing what normal healing looks like helps patients recognize when a symptom may be a warning sign.
Pain and Tenderness
Pain levels vary by procedure and patient. Patients may notice aching, tightness, burning, or tenderness around the treated area. Pain should usually become easier to manage as healing continues. 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. For several weeks or even months, swelling may conceal the true result of surgery. Bruising occurs when small blood vessels leak beneath the skin. Facial procedures, liposuction, breast surgery, and body contouring can all cause visible swelling and bruising.
The outcome of surgery should not be assessed before healing has progressed. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Numbness and Changes in Sensation
During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Some procedures commonly cause short-term numbness, tingling, increased sensitivity, or a decrease in feeling. Nerve recovery often improves sensation over time, but normal feeling may not return completely. In some cases, changes in sensation may be permanent.
Short-Term Activity Restrictions
Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. Restrictions may apply to driving, physical activity, lifting, swimming, and work. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Medical and Surgical Risks
Bleeding and Hematoma
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.
Some hematomas can be observed, while others must be drained. A return to the operating room may be necessary in more serious cases.
Infection
Infection may affect the skin, surgical cut, deeper tissue, or the area surrounding an implant. Warning signs can include spreading redness, heat, swelling, worsening pain, pus-like fluid, fever, chills, or an unusual odour.
Antibiotics, specialized wound care, drainage, or further surgery may be needed to treat an infection. Removal can be required when infection develops around a breast implant or surgical device. 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 develops when a pocket of clear fluid forms under the surgical tissues. 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. Repeated drainage may be necessary when a significant seroma develops. 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. When part of a deep vein clot moves into the lungs, it may block blood flow and cause a pulmonary embolism. 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
A surgical wound may take longer than expected to close or may start to open. Reduced blood supply, infection, tension on the wound, nicotine exposure, certain medications, and medical conditions can interfere with healing.
Incision problems may need wound care, antibiotics, surgical cleaning, or further corrective surgery. Secondary intention healing allows an open wound to fill and close naturally from the bottom upward. Healing in this way often takes more time and can result in a more noticeable scar.
Tissue Necrosis
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, vaping, and other nicotine use can greatly increase risk by narrowing blood vessels and reducing tissue oxygen.
Treatment depends on the amount of tissue affected. Possible treatment includes wound management, removal of dead tissue, a skin graft, reconstructive surgery, or revision at a later date.
Risks Related to Anesthesia
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.
Potential complications connected with anesthesia include:
- Postoperative nausea or vomiting
- Light-headedness, confusion, or extended sleepiness
- Headache or sore throat
- An allergic response or adverse drug reaction
- Fluctuations in blood pressure or disturbances in heartbeat
- Breathing difficulties
- Stomach contents entering the lungs, known as aspiration
- Injury to the teeth, lips, mouth, or airway
- Severe cardiac, respiratory, or neurological problems
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. 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. Incisions are often positioned in natural creases, along hairlines, or beneath clothing, although no scar can be removed entirely.
Scars often appear red, raised, firm, or darker during early healing. 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.
Hypertrophic and Keloid Scarring
A scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. Patients should inform their surgeon if they or close family members have developed raised or unusual scars.
Treatment options can include silicone sheets or gels, pressure treatment, corticocopyright injections, laser therapy, and scar revision. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return.
Pigment and Texture Irregularities
Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. Some of these changes resolve over time, while others can last permanently. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
Aesthetic Risks and Unsatisfactory Results
A procedure can be medically and technically successful while still producing a result the patient did not anticipate. The body's response is shaped by age, anatomy, skin quality, earlier surgery, scar development, and normal side-to-side differences.
Appearance-related problems may 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
- 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
Visual examples and digital imaging can guide consultation discussions, although no patient can be guaranteed the same outcome. Anatomy and healing responses vary from one person to another.
Corrective and Revision Surgery
Revision surgery may be considered when a complication occurs or when the result can be improved. Revision surgery carries risks of its own. Because scarred tissues may be less flexible and have reduced circulation, revision procedures can be more difficult.
Patients should ask what the clinic's revision policy covers. Surgeon fees, facility costs, anesthesia, implants, medications, travel, and time away from work may not all be included in the original price.
Risks Associated With Specific Cosmetic Procedures
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Possible Facelift and Neck Lift Complications
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
Potential rhinoplasty complications include long-lasting swelling, bleeding, infection, unevenness, altered smell, contour problems, a hole in the septum, structural collapse, and nasal breathing difficulty. The final shape may take a year or longer to become clear. Scar formation and altered cartilage can make secondary rhinoplasty more complex.
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 top plastic surgery visual changes. A patient should seek urgent care if severe eye pain or an abrupt change in vision occurs.
Risks of Cosmetic Breast Surgery
Procedures such as breast augmentation, mastopexy, and breast reduction can change nipple feeling, breast balance, scarring, and future breastfeeding ability. Additional complications can include bleeding beneath the tissue, infection, fat tissue death, slow wound healing, and changes to the nipple or areola location.
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. Health Canada publishes safety guidance concerning rare illnesses associated with some breast implants, including breast implant-associated anaplastic large cell lymphoma.
Liposuction Risks
Liposuction may lead to dents, surface irregularities, skin looseness, fluid problems, numbness, fluid collection, infection, organ injury, fat embolism, or lidocaine toxicity when local anesthesia is involved. Removing larger volumes of fat or treating several body areas may increase medical stress and recovery demands.
Risks of Abdominoplasty and Body Lift Surgery
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.
Possible Fat Grafting Complications
Fat transfer involves removing fat from one area and injecting it into another. 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 safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area.
Factors That Increase the Risk of Complications
A patient's health status and daily habits may make complications more likely. A patient may need medical testing, treatment changes, weight management, nicotine cessation, or clearance from another health professional before surgery.
The likelihood of complications may increase with:
- Cigarette smoking, vaping, or any form of nicotine use
- Diabetes that is not well controlled
- Heart, lung, kidney, liver, or blood vessel disease
- Past DVT, pulmonary embolism, or a diagnosed bleeding disorder
- Obesity or major weight changes
- Obstructive sleep apnea
- Immune system disorders
- Poor nutrition or significant anemia
- Previous radiation or surgery in the treatment area
- Medications or supplements that affect bleeding or healing
- Unrealistic expectations or untreated mental health concerns that affect decision-making
Having a risk factor does not always mean surgery is impossible. It means the surgeon must decide whether the procedure can be performed safely and whether changes are needed before proceeding.
Psychological Effects of Cosmetic Surgery
The effects of cosmetic surgery may be psychological and emotional, not only physical. Some patients feel anxious, impatient, or discouraged while swollen, bruised, tired, and unable to follow their normal routine. A short period of sadness or emotional difficulty after surgery is sometimes known as postoperative blues.
When a patient's expectations exceed the realistic limits of surgery, deeper or longer-lasting disappointment may follow. 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 is a mental health condition involving intense distress about perceived appearance flaws. Surgery may not relieve the underlying concern. In suitable cases, the surgeon may delay treatment and advise the patient to seek mental health assessment or counselling first.
Reducing the Chance of Surgical Complications
Although no operation can be made completely risk-free, thorough preparation can improve safety.
- Work with a properly trained physician whose practice includes the cosmetic operation you are considering.
- Confirm through your province or territory's college of physicians and surgeons that the doctor is licensed and in good standing.
- 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.
- When needed, organize transportation and early postoperative support from a responsible adult.
- Review the expected healing schedule before arranging employment, trips, strenuous activity, or important occasions.
- Attend all follow-up appointments and report unusual symptoms promptly.
- Your recovery should not be compared with social media images, promotional content, or another person's timeline.
- Do not make an early decision about revision, because the tissues may require many months to heal and stabilize.
How to Select a Cosmetic Surgeon in Canada
Medical regulation in Canada is handled at the provincial and territorial level. Patients can search the public register of the applicable college of physicians and surgeons to confirm a doctor's licence, registered specialty, and available practice information.
Another useful question is whether the doctor holds plastic surgery certification from the Royal College of Physicians and Surgeons of Canada. Certification is one useful qualification to review, but patients should also consider experience with the specific procedure, complication management, communication, surgical setting, and follow-up care.
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?
- Based on my health, goals, and anatomy, is this procedure suitable for me?
- Which problems do your patients experience most often after this operation?
- What low-frequency, high-impact risks should I know about?
- Who will provide anesthesia?
- What happens if I have a complication after business hours?
- What emergency plan is in place if I need urgent medical treatment?
- What follow-up visits are included?
- Which additional expenses would I be responsible for if a complication or revision occurs?
Understanding Informed Consent
Signing paperwork alone does not create true informed consent. It should be a continuing conversation that allows the patient to decide freely after receiving adequate information.
The consent process should cover the nature of the procedure, expected benefits, important risks, reasonable alternatives, recovery, limitations, and what could happen without treatment. Risks that are especially relevant to the patient's health, job, lifestyle, or personal priorities should also be discussed.
Patients should have enough time to review consent information without being pressured. Questions should be asked whenever risks, terminology, or instructions are not fully understood. 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:
- Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness
- Sudden swelling, pain, redness, or warmth in one leg
- Significant bleeding or swelling that expands quickly
- 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
- Possible tissue damage shown by abnormal colour, blistering, or low skin temperature
- Sudden vision loss, severe eye pain, or major visual changes
- Persistent vomiting that prevents normal hydration
- Any problem your surgeon specifically described as requiring emergency care
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
Canadian provincial and territorial health plans generally do not pay for operations performed solely for cosmetic reasons. Out-of-pocket expenses may include the surgeon, anesthesia provider, operating room, medical devices, recovery clothing, prescriptions, laboratory work, and follow-up items.
Before an operation, patients should ask who pays for treatment if a complication develops. Health coverage for complications varies based on medical necessity, treatment setting, and the applicable provincial or territorial insurance plan. Extra costs may arise from transportation, hotels, private nursing, lost income, family care, and corrective procedures.
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.
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. A decision not to operate is sometimes the safest and most responsible form of patient care.
Deciding Whether Cosmetic Surgery Is Right for You
Being aware of possible complications is not the same as believing they are certain to happen. Instead, risk awareness allows patients to decide using reliable facts rather than marketing, online trends, or cost as the only factor.
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.
