The shape, proportion, or overall appearance of the face and body can be enhanced through cosmetic surgery. 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 important part of deciding whether a procedure is right for you.
A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. Complications may result from anesthetic medication, bleeding, infection, delayed healing, unexpected reactions, or an individual response 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.
Patients in Canada should receive clear information about the expected benefits, material risks, alternatives, recovery requirements, and possible consequences of not having treatment. A careful consultation gives you time to consider this information 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. 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
- Incision-site or deep-tissue infection
- Seroma formation, which involves fluid collecting beneath the tissue
- Clots that form in a leg vein or travel to the lungs
- An incision that heals poorly, slowly, or begins to open
- Visible scarring that may be thick, widened, raised, or irregular
- Damage to nerves, loss of feeling, or changes in sensation
- Tissue damage or loss resulting from inadequate blood flow
- Allergic or adverse reactions involving anesthesia, medication, 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. Uncommon but severe risks can include serious infection, substantial bleeding, damage to an organ, cardiac complications, stroke, pulmonary embolism, lasting disability, or death.
Common Short-Term Effects After 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.
Soreness After Cosmetic Surgery
Pain levels vary by procedure and patient. Tightness, aching, burning, or tenderness may occur near the surgical area. Pain should usually become easier to manage as healing continues. Prompt medical advice is needed if pain suddenly worsens, begins spreading, or appears with fever, redness, breathing difficulty, or unexpected swelling.
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. 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.
Patients should not judge the final result too early. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Altered Sensation and Numbness
Small sensory nerves may be stretched, moved, or cut during surgery. Some procedures commonly cause short-term numbness, tingling, increased sensitivity, or a decrease in feeling. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. Permanent sensory changes are possible.
Activity Limitations During Recovery
During early recovery, patients may require support with transportation, meals, family duties, pets, household chores, and self-care. Driving, exercise, heavy lifting, swimming, and returning to work may be restricted. Failing to follow activity restrictions may raise the risk of bleeding, swelling, wound breakdown, and other problems.
Medical and Surgical Risks
Bleeding or Blood Collection
A small amount of bleeding may occur around an incision. When bleeding is more substantial, blood may collect under the skin or in the surgical site and form a hematoma. Possible signs of a hematoma include worsening pain, hard swelling, colour changes, or sudden asymmetry.
Some hematomas can be observed, while others must be drained. Some hematomas require another operation to control the bleeding and remove collected blood.
Infection After Cosmetic Surgery
The incision, nearby skin, deeper surgical tissues, or an implant pocket can become infected. 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. An infected breast implant or other medical device may need to be removed. Smoking, uncontrolled diabetes, poor nutrition, and problems with blood circulation can raise the risk of infection or make it harder to treat.
Postoperative Seroma
A seroma is a pocket of clear fluid that collects under the skin. 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. A larger seroma may require drainage on one or several occasions. A persistent seroma can create pressure, interfere with wound healing, and increase the chance of 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. This complication can be life-threatening and must be treated urgently.
Long procedures, inactivity, earlier blood clots, some drugs, nicotine use, excess body weight, health conditions, and combined operations can increase the chance of DVT or pulmonary embolism. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate.
Poor Wound Healing
Slow healing or separation of the incision can occur after cosmetic surgery. Factors such as reduced blood flow, infection, wound tension, nicotine use, medications, and illness may prevent normal healing.
Wound problems may require dressings, antibiotics, removal of damaged tissue, or additional 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.
Skin or Tissue Necrosis
Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and die. Tissue loss may occur after procedures involving extensive lifting, tightening, or repositioning. Nicotine exposure is an important avoidable risk because it constricts blood vessels and limits oxygen reaching the tissues.
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.
Potential Complications of Anesthesia
Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. The safest choice depends on the operation, the patient's medical history, the expected length of surgery, and the surgical setting.
Possible anesthesia-related problems include:
- Nausea and vomiting
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- Headache or sore throat
- Allergic or medication reactions
- Fluctuations in blood pressure or disturbances in heartbeat
- Problems with breathing
- Aspiration, which occurs when material from the stomach reaches the lungs
- Injury to the teeth, lips, mouth, or airway
- Major complications involving the heart, lungs, or nervous system
Before surgery, patients should disclose all prescription drugs, over-the-counter medications, vitamins, supplements, cannabis products, alcohol use, nicotine use, allergies, past anesthesia reactions, and relevant medical conditions. The safety of the operation can be reduced when important health information is omitted.
Scarring and Changes to the Skin
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. They may soften and fade over 12 months or longer. 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.
Treatment options can include silicone sheets or gels, pressure treatment, corticocopyright injections, laser therapy, and scar revision. Scar treatment may improve texture and appearance, but it cannot ensure that a hypertrophic scar or keloid will never come back.
Skin Colour and Texture Changes
Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin 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.
The Risk of an Unwanted Cosmetic Result
A technically successful operation does not always produce the appearance a patient expected. Healing is affected by anatomy, skin elasticity, age, previous surgery, scar formation, and natural differences between the two sides of the body.
Appearance-related problems may include:
- Persistent asymmetry
- Uneven contours or visible irregularities
- A result that is under-treated or over-treated
- A result that appears unnatural or excessively tight
- Changes in shape as swelling settles
- Movement or poor positioning of an implant
- Noticeable scars or scars in an unfavourable location
- Recurrence of sagging or tissue laxity over time
- 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.
Revision Cosmetic Surgery
Revision surgery may be considered when a complication occurs or when the result can be improved. A second procedure introduces another set of surgical risks. Scar tissue can make the procedure more complex, and the tissues may have less blood supply or flexibility than they did before the first surgery.
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.
Procedure-Specific Cosmetic Surgery Risks
Although many operations share common complications, every cosmetic procedure has its own specific risks.
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. Because nicotine restricts circulation, its use can greatly increase wound and skin-healing complications.
Rhinoplasty Risks
After nose surgery, patients may experience persistent swelling, nosebleeds, infection, asymmetry, smell changes, irregular contours, septal perforation, collapse of nasal support, or obstructed breathing. 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
After blepharoplasty, patients may develop dry eyes, irritation, blurred vision, trouble shutting the eyelids, lid malposition, asymmetry, scarring, orbital bleeding, or changes in eyesight. Immediate medical evaluation is needed for intense eye pain or a sudden visual disturbance.
Possible Breast Procedure Complications
Procedures such as breast augmentation, mastopexy, and breast reduction can change 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. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. 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.
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. Removing larger volumes of fat or treating several body areas may increase medical stress and recovery demands.
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.
Fat Grafting Risks
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. Additional complications include dead fat tissue, cysts, calcification, infection, oil cysts, and fat entering a blood vessel. The location where fat is injected, such as the face, breasts, or buttocks, affects the type and seriousness of potential complications.
Who May Face Greater Cosmetic Surgery Risks?
Some health and lifestyle factors can raise the chance of complications. Before proceeding, some patients require tests, adjustments to treatment, weight changes, nicotine cessation, or approval from another medical professional.
Factors associated with higher surgical risk include:
- Exposure to nicotine through smoking, vaping, gum, patches, or other products
- 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, unstable weight, or recent major weight loss or gain
- Obstructive sleep apnea
- Conditions affecting the immune system
- Nutritional deficiencies or a low red blood cell count
- Earlier surgery or radiation therapy involving the same area
- Drugs, vitamins, or supplements that interfere with clotting or tissue repair
- Unrealistic expectations or untreated mental health concerns that affect 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 and Emotional Risks
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. This temporary low mood is sometimes called postoperative blues.
When a patient's expectations exceed the realistic limits of surgery, deeper or longer-lasting disappointment may follow. Cosmetic surgery may change a physical feature, but it cannot guarantee confidence, repair a relationship, create career success, or solve broader personal problems.
A responsible assessment should explore the patient's reasons for seeking surgery. 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 is a mental health condition involving intense distress about perceived appearance flaws. Surgery may not relieve the underlying concern. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation.
Reducing the Chance of Surgical Complications
Cosmetic surgery always carries some risk, yet careful planning can reduce the likelihood of complications.
- Work with a properly trained physician whose practice includes the cosmetic operation you are considering.
- Verify the physician's registration and standing through the medical regulatory authority in your province or territory.
- Find out which facility will be used and whether it has suitable emergency plans, safety standards, and infection prevention measures.
- Disclose your entire health history, including previous surgery, allergies, medications, supplements, alcohol, cannabis, and nicotine use.
- Follow instructions about fasting, medication changes, testing, and stopping nicotine.
- 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.
- 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.
Patients may also ask whether a surgeon is certified in plastic surgery by 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?
- Which problems do your patients experience most often after this operation?
- Which uncommon but severe complications need to be considered?
- 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?
- Which follow-up visits and services are included in the fee?
- What costs could arise if I need treatment or revision surgery?
Informed Consent for Cosmetic Surgery
Signing paperwork alone does not create true informed consent. 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. Any complication that could significantly affect the patient's medical condition, employment, lifestyle, or priorities should receive special attention.
No one should be pushed into signing a surgical consent form quickly. 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.
When to Seek Help After Cosmetic Surgery
Patients should receive clear directions about warning signs, emergency care, and after-hours communication. Contact the clinic promptly when symptoms are unexpected, worsening, or different from the recovery plan.
Potential emergency signs after cosmetic surgery include:
- Chest pain, shortness of breath, coughing blood, or fainting
- Unexpected pain, swelling, redness, or heat affecting one leg
- Significant bleeding or swelling that expands quickly
- Severe pain that is not controlled by prescribed medication
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Confusion, extreme weakness, or difficulty staying awake
- A pale, dark, blistered, or unusually cold area of skin
- Loss of sight, intense eye pain, or an abrupt disturbance in vision
- Ongoing vomiting or difficulty drinking without becoming sick
- Any symptom the surgical team identified as an emergency
When a symptom could represent a life-threatening emergency, call 911 or go to an emergency department. 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.
The financial responsibility for postoperative problems should be clarified in advance. Health coverage for complications varies based on medical necessity, treatment setting, and the applicable provincial or territorial insurance plan. 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.
Balancing the Benefits and Risks of Cosmetic Surgery
Patients should consider surgery only when their goals are achievable, their health is suitable, and they understand the risks and recovery. A suitable patient recognizes that improvement is possible, but perfection is not.
Patients should carefully weigh likely improvements against health risks, emotional effects, recovery demands, and financial costs. Think about your ability to obey postoperative instructions, live with scars, take enough time off, aesthetic cosmetic surgery and emotionally manage an outcome that is not ideal.
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.
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.
A safer decision involves understanding the procedure, identifying individual risk factors, checking the surgeon's qualifications, discussing concerns, and organizing postoperative care. A complete understanding of the likely improvements, procedure limitations, available options, and associated risks helps patients determine whether cosmetic surgery is appropriate for them.
