Through cosmetic surgery, patients may refine the shape, proportions, or appearance of their face or body. For some people, it can also reduce concern about a physical feature that has caused distress for years. Even so, every surgical procedure involve some uncertainty. Before deciding whether a procedure is suitable, it is essential to understand the risks of cosmetic surgery.
A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. 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. 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. Most cosmetic procedures are optional, which means you can delay or decline surgery when its risks do not justify its likely benefits.
Understanding 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.
It is normal for patients to experience some minor effects after many operations. 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.
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
- 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
- Nerve-related problems, including numbness or unusual sensation
- Loss of skin, fat, or other tissue because of reduced circulation
- Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products
- Unevenness, contour irregularities, or an unsatisfactory appearance
- Changes in function, such as breathing, movement, or sensation
- Additional medical treatment or a revision operation
Serious complications are uncommon, but they are still important to discuss. Rare risks may include severe infection, major blood loss, organ injury, heart problems, stroke, pulmonary embolism, permanent disability, or death.
Common Early Effects During Cosmetic Surgery Recovery
Normal recovery often includes temporary discomfort and changes in appearance or sensation. Knowing what normal healing looks like helps patients recognize when a symptom may be a warning sign.
Soreness After Cosmetic Surgery
Each patient experiences pain differently, and some operations cause more discomfort than others. Tightness, aching, burning, or tenderness may occur near the surgical 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.
Swelling and Bruising
Swelling is caused by inflammation and fluid moving into the treated tissues. 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 are advised to avoid making early judgments about their final appearance. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Altered Sensation and Numbness
Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. Temporary numbness, tingling, sensitivity, or reduced feeling is common after some operations. Nerve recovery often improves sensation over time, but normal feeling may not return completely. Permanent sensory changes are possible.
Activity Limitations During Recovery
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. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored.
Medical and Surgical Risks
Postoperative Bleeding and Hematoma
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. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
A small hematoma may only need monitoring, but a larger one advanced cosmetic surgery may require drainage. 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. An infection may cause increasing warmth, redness, swelling, pain, discharge resembling pus, fever, chills, or a bad smell.
Antibiotics, specialized wound care, drainage, or further surgery may be needed to treat an infection. If a breast implant or another implanted device becomes infected, removal may be necessary. Smoking, uncontrolled diabetes, poor nutrition, and problems with blood circulation can raise the risk of infection or make it harder to treat.
Fluid Buildup or Seroma
A seroma develops when a pocket of clear fluid forms under the surgical tissues. 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.
Small seromas may resolve as the body absorbs the fluid. Larger ones may need to be drained, sometimes more than once. A persistent seroma can create pressure, interfere with wound healing, and increase the chance of 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. When part of a deep vein clot moves into the lungs, it may block blood flow and cause a pulmonary embolism. A pulmonary embolism requires emergency medical care.
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
Slow healing or separation of the incision can occur after cosmetic surgery. 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. The recovery period may be extended, and the final scar may be more prominent.
Tissue Necrosis
Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to die. This complication can occur after procedures that lift, tighten, or reposition large sections of tissue. 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. It may involve wound care, removal of damaged tissue, skin grafting, reconstructive surgery, or a delayed revision.
Anesthesia Risks in Cosmetic Surgery
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.
Potential complications connected with anesthesia include:
- Nausea and vomiting
- Dizziness, confusion, or prolonged drowsiness
- Headache or sore throat
- An allergic response or adverse drug reaction
- Abnormal blood pressure or irregular heart rhythm
- Respiratory difficulty
- Aspiration of stomach contents into the lungs
- Damage to teeth, lips, or the airway
- 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.
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.
Early scars can be firm, raised, reddish, or more deeply coloured before they mature. Over 12 months or longer, scar tissue can gradually fade and soften. Genetic factors, skin characteristics, pressure on the incision, infection, sunlight, wound care, surgical location, and procedure type all influence the finished scar.
Raised Scars and Keloid Formation
Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. A keloid grows beyond the borders of the incision. People with a personal or family history of abnormal scarring should tell their surgeon before surgery.
Raised or visible scars may be treated with silicone, compression, copyright injections, laser procedures, or surgical 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. Some of these changes resolve over time, while others can last permanently. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
The Risk of an Unwanted Cosmetic Result
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:
- 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
- Noticeable scars or scars in an unfavourable location
- 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. Each patient has different anatomy and heals in a different way.
Revision Cosmetic 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.
It is important to ask how the practice handles revisions and which expenses are covered. 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
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. Smoking, vaping, and other nicotine exposure can significantly raise the chance of skin loss and delayed healing.
Risks of Nose Surgery
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. A revision nose operation is often more challenging because the first surgery changes the cartilage and creates internal scarring.
Blepharoplasty Risks
After blepharoplasty, patients may develop dry eyes, irritation, blurred vision, trouble shutting the eyelids, lid malposition, asymmetry, scarring, orbital bleeding, or changes in eyesight. A patient should seek urgent care if severe eye pain or an abrupt change in vision occurs.
Possible Breast Procedure Complications
Procedures such as breast augmentation, mastopexy, and breast reduction can change nipple feeling, breast balance, scarring, and future breastfeeding ability. Hematoma, infection, fat necrosis, poor healing, and altered nipple or areola position are also possible.
Patients with breast implants face additional concerns that can develop over time. Capsular contracture, rupture, deflation, rippling, displacement, rotation, pain, ongoing imaging, and future surgery may occur with breast implants. Breast implants are not designed to last for an entire lifetime. Health Canada publishes safety guidance concerning rare illnesses associated with some breast implants, including breast implant-associated anaplastic large cell lymphoma.
Liposuction Risks
Liposuction complications may include contour irregularities, dents, rippling, loose skin, fluid imbalance, numbness, seroma, infection, internal injury, fat embolism, and lidocaine toxicity when local anesthetic is used. High-volume liposuction and treatment of several regions can place greater stress on the body and make recovery more demanding.
Risks of Abdominoplasty and Body Lift Surgery
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. Possible complications include fluid buildup, DVT, infection, tissue loss, incision opening, reduced sensation, visible scars, and changes in navel shape or placement. Patients may need several weeks of movement restrictions.
Possible Fat Grafting Complications
Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. The body naturally absorbs some transferred fat, potentially reducing volume or creating asymmetry. Fat grafting may also cause fat necrosis, cyst formation, calcium deposits, infection, oily fluid collections, or unintended injection into circulation. 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
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.
The likelihood of complications may increase with:
- Smoking, vaping, or using nicotine products
- Poorly controlled diabetes
- Cardiac, respiratory, renal, liver, or vascular conditions
- Past DVT, pulmonary embolism, or a diagnosed bleeding disorder
- A high body mass index or significant changes in weight
- Obstructive sleep apnea
- Conditions affecting the immune system
- Poor nutrition or significant anemia
- Previous radiation or surgery in the treatment area
- Drugs, vitamins, or supplements that interfere with clotting or tissue repair
- Mental health concerns or unrealistic goals that interfere with informed 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. 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. A cosmetic procedure can modify the body, but it does not guarantee emotional confidence, relationship improvement, career advancement, or solutions to unrelated personal concerns.
A responsible assessment should explore the patient's reasons for seeking surgery. 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. Surgery may not relieve the underlying concern. A psychological evaluation or professional support may be recommended before surgery when concerns are identified.
How to Reduce the Risks of Cosmetic Surgery
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.
- 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.
- 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.
- 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
Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. The public directory of the appropriate college of physicians and surgeons can be used to check licensing, specialty registration, and listed practice details.
Canadian patients can ask if their surgeon has been certified in plastic surgery by 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 training and certification do you have?
- How often do you perform this procedure?
- Does my medical history and physical anatomy make me an appropriate candidate?
- What are the most common complications in your practice?
- What low-frequency, high-impact risks should I know about?
- Who is responsible for anesthesia care during the operation?
- Who should I contact if I experience a complication outside normal clinic hours?
- What emergency plan is in place if I need urgent medical treatment?
- How many postoperative appointments are provided as part of the surgical plan?
- Could I face extra surgeon, facility, anesthesia, medication, or revision fees?
What Informed Consent Should Include
Informed consent involves more than placing a signature on a document. It is an ongoing discussion that should give the patient enough information to make a voluntary decision.
A proper consent discussion includes the procedure itself, expected improvement, significant complications, alternative options, recovery requirements, limitations, and the choice to decline 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. When medical language or a possible complication is confusing, the patient should request a clearer explanation. Taking notes, involving a support person, and reviewing written material outside the clinic can support an informed decision.
Postoperative Warning Signs
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.
Potential emergency signs after cosmetic surgery include:
- Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness
- One-sided leg swelling, tenderness, warmth, or discolouration
- Significant bleeding or swelling that expands quickly
- Severe pain that is not controlled by prescribed medication
- 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
- A symptom listed as urgent in the postoperative instructions
Call 911 or seek emergency care when symptoms may be life-threatening. Patients should seek immediate care rather than waiting for the surgeon's office when serious bleeding, breathing problems, chest pain, fainting, or another critical symptom occurs.
Financial Considerations for Cosmetic Surgery in Canada
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.
Complication-related costs should be discussed before surgery. Health coverage for complications varies based on medical necessity, treatment setting, and the applicable provincial or territorial insurance plan. Patients should budget for possible travel, lodging, caregiving, time away from employment, child care, and future revision surgery.
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.
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. Realistic patients seek meaningful improvement while accepting that no procedure can deliver a flawless result.
Before deciding, compare what the operation may achieve with its physical, psychological, practical, and economic consequences. 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.
A responsible surgeon may decline surgery if the patient's risk level is unacceptable, the likely improvement is minimal, or the desired result is unrealistic. A decision not to operate is sometimes the safest and most responsible form of patient care.
Deciding Whether Cosmetic Surgery Is Right for You
Being aware of possible complications is not the same as believing they are certain to happen. It means making a thoughtful decision based on accurate information rather than advertising, social media trends, or price alone.
Learn about the procedure, review your personal risk factors, confirm the surgeon's qualifications, ask detailed questions, and plan for a full recovery. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
