The shape, proportion, or overall appearance of the face and body can be enhanced through cosmetic surgery. For some people, it can also reduce concern about a physical feature that has caused distress for years. However, every operation involves 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. During a careful consultation, patients should be able to consider the facts without being rushed. 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.
Understanding the Risks of Cosmetic Surgery
The risks of cosmetic surgery include unwanted outcomes that affect health, physical function, or appearance. The type and level of risk depend on the procedure, the surgical technique, the area being treated, the length of the operation, the form of anesthesia, and the patient's overall health.
Many cosmetic procedures are followed by mild expected side effects. Swelling, bruising, soreness, numbness, tightness, fatigue, and mild drainage may be normal during early healing. A complication is different. A complication extends beyond normal recovery and may need medical care.
Plastic surgery complications may include the following:
- A hematoma, which is a collection of blood, or other excessive bleeding
- Incision-site or deep-tissue infection
- Seroma formation, which involves fluid collecting beneath the tissue
- Blood clots in the legs or lungs
- Slow wound healing or separation of the incision
- Visible scarring that may be thick, widened, raised, or irregular
- Damage to nerves, loss of feeling, or changes in sensation
- Loss of skin, fat, or other tissue because of reduced circulation
- Reactions to anesthesia, medications, adhesives, or surgical materials
- Aesthetic concerns such as asymmetry, poor contours, or an unwanted result
- Changes in function, such as breathing, movement, or sensation
- 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 Short-Term Effects After Cosmetic Surgery
Normal recovery often includes temporary discomfort and changes in appearance or sensation. Patients who understand expected recovery are better able to separate routine symptoms from possible complications.
Postoperative Pain and Tenderness
Pain levels vary by procedure and patient. The surgical site can feel tender, tight, sore, or mildly burning during recovery. Discomfort is normally expected to improve gradually during healing. Prompt medical advice is needed if pain suddenly worsens, begins spreading, or appears with fever, redness, breathing difficulty, or unexpected swelling.
Postoperative Swelling and Bruising
Inflammation and the movement of fluid into surgical tissues cause swelling. It may hide the initial surgical result for weeks or months. Small blood vessels can release blood under the skin, creating bruising. Patients undergoing face surgery, breast surgery, liposuction, or body contouring may experience noticeable bruising and swelling.
Patients are advised to avoid making early judgments about their final appearance. Residual swelling can change shape, symmetry, and skin texture during recovery.
Altered Sensation and Numbness
During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Temporary numbness, tingling, sensitivity, or reduced feeling is common after some operations. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. There is a possibility that altered feeling will not fully resolve.
Temporary Limits on Activity
During early recovery, patients may require support with transportation, meals, family duties, pets, household chores, and self-care. Restrictions may apply to driving, physical activity, lifting, swimming, and work. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored.
Potential Surgical Complications
Bleeding or Blood Collection
Minor bleeding near a surgical incision can occur during early recovery. 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.
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.
Infection
Infection may affect the skin, surgical cut, deeper tissue, or the area surrounding 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. 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.
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. A pulmonary embolism can occur if a piece of the clot breaks away and reaches the lungs. This is a medical emergency.
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.
Delayed or Difficult Wound Healing
Slow healing or separation of the incision can occur after cosmetic surgery. Reduced blood cosmetic surgeon supply, infection, tension on the wound, nicotine exposure, certain medications, and medical conditions can interfere with healing.
Wound problems may require dressings, antibiotics, removal of damaged tissue, or additional surgery. Healing by secondary intention means allowing an open area to close gradually from the inside outward. The recovery period may be extended, and the final scar may be more prominent.
Tissue Necrosis
When skin, fat, or other tissue loses its blood supply and starts to die, the condition is called necrosis. Operations that move, tighten, or lift broad areas of tissue can carry a risk of necrosis. Smoking, vaping, and other nicotine use can greatly increase risk by narrowing blood vessels and reducing tissue oxygen.
The extent of tissue damage determines which treatment is required. Possible treatment includes wound management, removal of dead tissue, a skin graft, reconstructive surgery, or revision at a later date.
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:
- Nausea and vomiting
- Light-headedness, confusion, or extended sleepiness
- Throat discomfort or headache
- Allergic or medication reactions
- Changes in blood pressure or heart rhythm
- Problems with breathing
- Aspiration of stomach contents into the lungs
- Damage to teeth, lips, or the airway
- Severe cardiac, respiratory, or neurological problems
Patients must provide complete information about prescriptions, non-prescription drugs, vitamins, supplements, cannabis, alcohol, nicotine, allergies, earlier anesthesia problems, and medical conditions before surgery. The safety of the operation can be reduced when important health information is omitted.
Changes in Scarring, Colour, and Skin Texture
Whenever an incision is made through the skin, a scar will form. 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. How a scar eventually looks is affected by heredity, skin type, wound tension, infection, ultraviolet exposure, aftercare, incision placement, and the operation performed.
Hypertrophic Scars and Keloids
A hypertrophic scar becomes thick or raised but stays within the original wound. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. A history of hypertrophic scars or keloids, whether personal or familial, should be discussed before an operation.
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.
Skin Colour and Texture Changes
Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin texture. These effects may be temporary or permanent. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
The Risk of an Unwanted Cosmetic Result
Even when surgery is performed correctly, the final appearance may not match the patient's expectations. Healing is affected by anatomy, skin elasticity, age, previous surgery, scar formation, and natural differences between the two sides of the body.
Possible aesthetic concerns include:
- Unevenness that remains after healing
- Uneven contours or visible irregularities
- Too little or too much correction
- An unnatural or overly tight appearance
- A changing contour as postoperative swelling decreases
- An implant that shifts, rotates, or sits incorrectly
- Noticeable scars or scars in an unfavourable location
- Recurrence of sagging or tissue laxity over time
- Patient dissatisfaction even when the result is medically acceptable
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.
Revision Cosmetic Surgery
When problems occur or the outcome may benefit from improvement, revision cosmetic surgery can be considered. Revision surgery carries risks of its own. 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
Hematoma, facial nerve injury, hairline alteration, hair loss around incisions, skin necrosis, contour problems, earlobe changes, loss of feeling, facial weakness, and visible scarring are among the risks of facelift and neck lift surgery. Smoking, vaping, and other nicotine exposure can significantly raise the chance of skin loss and delayed healing.
Risks of Nose Surgery
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. 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.
Eyelid Surgery Risks
Possible eyelid surgery complications include eye dryness, irritation, short-term blurred vision, incomplete eyelid closure, abnormal lid position, unevenness, scars, bleeding behind the eye, and visual changes. Severe eye pain or a sudden change in vision requires urgent medical assessment.
Possible Breast Procedure Complications
Nipple sensation, symmetry, scars, and the ability to breastfeed may be affected by breast augmentation, breast lift surgery, or breast reduction. Hematoma, infection, fat necrosis, poor healing, and altered nipple or areola position are also possible.
Breast implants bring added long-term considerations. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. Patients should not assume that breast implants will remain in place permanently without further care. Health Canada also provides safety information about uncommon conditions linked with certain 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. 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
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. Recovery may involve several weeks of limited movement and physical activity.
Fat Grafting Risks
Fat transfer involves removing fat from one area and injecting it into another. The body naturally absorbs some transferred fat, potentially reducing volume or creating asymmetry. Other risks include fat necrosis, cysts, calcification, infection, oil cysts, and accidental injection into a blood vessel. Fat transfer risks vary according to whether the treatment area is the face, breast, buttocks, or another body region.
Who May Face Greater Cosmetic Surgery Risks?
Some health and lifestyle factors can raise the chance of complications. A patient may need medical testing, treatment changes, weight management, nicotine cessation, or clearance from another health professional before surgery.
Factors associated with higher surgical risk include:
- Smoking, vaping, or using nicotine products
- Diabetes with unstable or elevated blood sugar
- Heart, lung, kidney, liver, or blood vessel disease
- A clotting or bleeding condition, or previous blood clots
- A high body mass index or significant changes in weight
- Obstructive sleep apnea
- Conditions affecting the immune system
- Inadequate nutrition or serious anemia
- Earlier surgery or radiation therapy involving the same area
- Medications or supplements that affect bleeding or healing
- 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. It means the surgeon must decide whether the procedure can be performed safely and whether changes are needed before proceeding.
Emotional and Mental Health Considerations
Cosmetic surgery can affect emotional health as well as physical health. During recovery, patients can become anxious or discouraged because they look swollen, feel tired, and cannot resume normal activities. This temporary low mood is sometimes called postoperative blues.
More serious dissatisfaction can occur when expectations do not match what surgery can realistically achieve. Although surgery can alter appearance, it cannot promise self-confidence, fix relationships, ensure professional success, or resolve wider life difficulties.
A 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.
Intense and persistent concern about perceived physical defects may be a sign of body dysmorphic disorder, a recognized mental health condition. Changing the physical feature does not necessarily treat the underlying mental health condition. In suitable cases, the surgeon may delay treatment and advise the patient to seek mental health assessment or counselling first.
Ways to Lower Cosmetic Surgery Risks
Risk cannot be removed completely, but careful planning can make cosmetic surgery safer.
- Work with a properly trained physician whose practice includes the cosmetic operation you are considering.
- Check the doctor's licence, registration, and professional standing with the applicable provincial or territorial medical regulator.
- 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.
- Carefully follow all directions related to eating, drinking, preoperative tests, medication adjustments, and nicotine cessation.
- When needed, organize transportation and early postoperative support from a responsible adult.
- 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.
- Wait until healing is mature before deciding whether revision surgery is needed.
How to Select a Cosmetic Surgeon in Canada
In Canada, physicians are licensed and regulated by provincial and territorial authorities. 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. While certification matters, patients should also assess procedure-specific experience, communication, the quality of the facility, aftercare, and the surgeon's approach to complications.
During the consultation, patients may wish to ask:
- What professional education and certifications have you completed?
- How many times have you carried out this operation?
- 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?
- 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?
- What costs could arise if I need treatment or revision surgery?
What Informed Consent Should Include
Informed consent involves more than placing a signature on a document. 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. Any complication that could significantly affect the patient's medical condition, employment, lifestyle, or priorities should receive special attention.
Patients should have enough time to review consent information without being pressured. Ask for clarification when a term or complication is unclear. 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.
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
- Uncontrolled bleeding or a sudden increase in swelling
- Severe pain that is not controlled by prescribed medication
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Mental confusion, severe weakness, or unusual inability to remain alert
- Skin that becomes very pale, dark, blistered, or cold to the touch
- An emergency eye symptom such as severe pain, sudden visual change, or vision loss
- 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. Do not wait for an office to reopen when there is severe breathing trouble, chest pain, loss of consciousness, major bleeding, or another urgent concern.
Financial 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.
Complication-related costs should be discussed before surgery. 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.
Anyone travelling outside Canada for cosmetic surgery should arrange appropriate postoperative care before coming home. An inexpensive overseas package may exclude the cost of treating infection, poor healing, DVT, implant problems, and corrective operations.
Weighing Cosmetic Surgery Benefits Against Risks
A sound decision about cosmetic surgery requires realistic expectations, appropriate health, informed consent, and knowledge of the healing process. 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. 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. A decision not to operate is sometimes the safest and most responsible form of patient care.
Deciding Whether Cosmetic Surgery Is Right for You
Understanding the risks of cosmetic surgery does not mean assuming that complications will occur. 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.
