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. Even so, all operations involve some uncertainty. A careful decision about cosmetic surgery should include a clear understanding of its possible risks.
Although most patients heal without serious problems, no surgeon can guarantee perfection or eliminate every surgical risk. Complications may result from anesthetic medication, bleeding, infection, delayed healing, unexpected reactions, or an individual response to surgery. Certain complications are temporary and can be treated without major intervention. In other cases, a complication can require drugs, hospital care, another operation, or extended monitoring.
In Canada, patients should be clearly informed about expected benefits, important risks, treatment alternatives, recovery needs, and what may happen if they decline surgery. 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 Risks Can Cosmetic Surgery Involve?
Cosmetic surgery risks include any unwanted medical, functional, or aesthetic outcome linked to an operation. 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. Expected healing effects and surgical complications are different. A complication extends beyond normal recovery and may need medical care.
Plastic surgery complications may include the following:
- Bleeding or the development of a blood collection known as 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
- Delayed wound healing or wound separation
- Noticeable, raised, widened, or uneven scars
- Damage to nerves, loss of feeling, or changes in sensation
- Loss of skin, fat, or other tissue because of reduced circulation
- Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products
- Asymmetry, contour problems, or an unwanted appearance
- Changes in function, such as breathing, movement, 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.
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.
Postoperative Pain and Tenderness
Each patient experiences pain differently, and some operations cause more discomfort than others. Tightness, aching, burning, or tenderness may occur near the surgical area. As recovery progresses, pain should generally become less intense and easier to control. Patients should quickly report severe or spreading pain, especially when it is accompanied by fever, redness, shortness of breath, or unusual swelling.
Swelling and Bruising
Swelling is caused by inflammation and fluid moving into the treated tissues. 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 should not judge the final result too early. Remaining swelling may temporarily affect shape, balance, and the texture of the skin.
Altered Sensation and Numbness
Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. Some procedures commonly cause short-term numbness, tingling, increased sensitivity, or a decrease in feeling. Feeling frequently returns as the nerves heal, although full recovery is not certain. In some cases, changes in sensation may be permanent.
Temporary Limits on Activity
Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. Driving, exercise, heavy lifting, swimming, and returning to work may be restricted. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored.
Potential Surgical Complications
Postoperative 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. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a cosmetic surgical procedures sudden difference between two sides of the body.
A small hematoma may only need monitoring, but a larger one may require drainage. In certain cases, the patient may need to return to the operating room.
Infection After Cosmetic Surgery
The incision, nearby skin, deeper surgical tissues, or an implant pocket can become infected. An infection may cause increasing warmth, redness, swelling, pain, discharge resembling pus, fever, chills, or a bad smell.
Treatment may involve antibiotics, wound care, drainage, or another operation. Removal can be required when infection develops around a breast implant or surgical device. Smoking, uncontrolled diabetes, poor nutrition, and problems with blood circulation can raise the risk of infection or make it harder to treat.
Postoperative Seroma
Clear fluid that gathers beneath the skin is known as a seroma. 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.
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.
Deep Vein Thrombosis 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. When part of a deep vein clot moves into the lungs, it may block blood flow and cause a pulmonary embolism. This is a medical emergency.
Risk may increase with long operations, limited movement, previous blood clots, certain medications, nicotine use, obesity, some medical conditions, and combining multiple procedures. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate.
Poor Wound Healing
An incision may heal slowly or begin to separate. 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. 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.
Loss of Tissue From Poor Blood Supply
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.
Treatment depends on the amount of tissue affected. It may involve wound care, removal of damaged tissue, skin grafting, reconstructive surgery, or a delayed revision.
Potential Complications of Anesthesia
Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. Choosing an anesthesia method requires consideration of the operation, medical background, expected surgical time, and facility.
Possible anesthesia-related problems include:
- Nausea and vomiting
- Dizziness, confusion, or prolonged drowsiness
- Throat discomfort or headache
- An allergic response or adverse drug reaction
- Abnormal blood pressure or irregular heart rhythm
- Respiratory difficulty
- Aspiration of stomach contents into the lungs
- Injury to the teeth, lips, mouth, or airway
- Major complications involving the heart, lungs, or nervous system
Patients must provide complete information about prescriptions, non-prescription drugs, vitamins, supplements, cannabis, alcohol, nicotine, allergies, earlier anesthesia problems, and medical conditions before surgery. Withholding medical or lifestyle information may increase the risks of anesthesia and surgery.
Changes in Scarring, Colour, and Skin Texture
Whenever an incision is made through the skin, a scar will form. A surgeon may try to conceal incisions in folds, hair-bearing areas, or covered locations, but complete scar elimination is not possible.
During the first stages of healing, scars may look red, thick, firm, elevated, or darker than nearby skin. 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.
Hypertrophic and Keloid Scarring
A scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. Keloid tissue spreads past the edges of the initial incision. 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. Scar treatment may improve texture and appearance, but it cannot ensure that a hypertrophic scar or keloid will never come back.
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. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
Cosmetic Outcome Risks and Patient Dissatisfaction
A procedure can be medically and technically successful while still producing a result the patient did not anticipate. 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:
- Unevenness that remains after healing
- Uneven contours or visible irregularities
- Under-correction or over-correction
- An unnatural or overly tight appearance
- A changing contour as postoperative swelling decreases
- Implant position problems
- Scarring that is prominent or difficult to conceal
- A return of looseness or sagging with age and time
- Disappointment with an outcome that falls within an acceptable surgical range
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.
The Possibility of Revision 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. A second operation may be technically harder because previous surgery can leave scar tissue, stiffness, and diminished blood flow.
It is important to ask how the practice handles revisions and which expenses are covered. Additional costs for the surgeon, operating room, anesthetic, implants, medicine, transportation, accommodation, and missed employment may fall outside the initial price.
Procedure-Specific Cosmetic Surgery Risks
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Facelift and Neck Lift Risks
Facelift and neck lift complications may include hematoma, facial nerve injury, hairline changes, hair loss near incisions, skin loss, contour irregularities, earlobe distortion, numbness, facial weakness, and visible scarring. Smoking, vaping, and other nicotine exposure can significantly raise the chance of skin loss and delayed healing.
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. The final shape may take a year or longer to become clear. Revision rhinoplasty can be more difficult because of scar tissue and changes to the cartilage.
Eyelid Surgery 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. Severe eye pain or a sudden change in vision requires urgent medical assessment.
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.
Implant-based breast surgery involves long-term risks beyond the normal surgical recovery period. 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.
Risks of Liposuction
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. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated.
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. 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. Some of the transferred fat will be absorbed, which can affect volume and symmetry. 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
Certain medical conditions and lifestyle habits increase surgical risk. A patient may need medical testing, treatment changes, weight management, nicotine cessation, or clearance from another health professional before surgery.
Risk factors may include:
- Cigarette smoking, vaping, or any form of nicotine use
- 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
- Inadequate nutrition or serious anemia
- Scar tissue or circulation changes from prior operations or radiation
- 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. The surgeon needs to evaluate the level of risk and decide whether health or lifestyle changes are necessary before treatment.
Psychological and Emotional Risks
An operation performed for appearance can influence a patient's mental and emotional state in addition to the body. During recovery, patients can become anxious or discouraged because they look swollen, feel tired, and cannot resume normal activities. This temporary low mood is sometimes called postoperative blues.
Significant dissatisfaction is more likely when the expected transformation is not medically achievable. 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. 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.
Intense and persistent concern about perceived physical defects may be a sign of body dysmorphic disorder, a recognized mental health condition. An operation may fail to resolve the deeper psychological distress. 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
Risk cannot be removed completely, but careful planning can make cosmetic surgery safer.
- Choose a properly qualified physician with training and experience relevant to the procedure.
- 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.
- Carefully follow all directions related to eating, drinking, preoperative tests, medication adjustments, and nicotine cessation.
- Arrange a responsible adult to drive you home and assist during early recovery when required.
- Understand the recovery timeline before booking work, travel, exercise, or major events.
- Follow-up care should not be skipped, and abnormal changes should be reported without delay.
- Your recovery should not be compared with social media images, promotional content, or another person's timeline.
- Allow swelling and scar tissue to settle fully before considering corrective surgery.
Choosing a Cosmetic Surgeon in Canada
Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. Patients 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. Royal College certification is valuable, but it should be considered alongside relevant experience, patient communication, emergency planning, surgical environment, and postoperative support.
Useful questions for a cosmetic surgery consultation include:
- 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?
- Which uncommon but severe complications need to be considered?
- Who is responsible for anesthesia care during the operation?
- Who should I contact if I experience a complication outside normal clinic hours?
- Which hospital or emergency facility would treat me if a serious problem occurred?
- What follow-up visits are included?
- 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.
Patients should be informed about how the operation works, its likely benefits, material risks, alternatives, healing process, limits, and the possible consequences of no surgery. Any complication that could significantly affect the patient's medical condition, employment, lifestyle, or priorities should receive special attention.
A patient should never feel rushed to sign. Ask for clarification when a term or complication is unclear. Patients may benefit from writing down information, attending with someone they trust, and reading the documents again at home.
Warning Signs After Cosmetic Surgery
The surgeon's office should explain which symptoms require attention and copyright the appropriate provider. The surgical team should be contacted quickly if symptoms become worse, appear unusual, or do not match the expected healing process.
Symptoms that may require urgent care include:
- Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness
- One-sided leg swelling, tenderness, warmth, or discolouration
- Uncontrolled bleeding or a sudden increase in swelling
- Pain that remains severe despite the prescribed treatment plan
- High fever, chills, spreading redness, or pus-like drainage
- Disorientation, marked weakness, or excessive drowsiness
- Skin that becomes very pale, dark, blistered, or cold to the touch
- Loss of sight, intense eye pain, or an abrupt disturbance in vision
- Persistent vomiting that prevents normal hydration
- A symptom listed as urgent in the postoperative instructions
When a symptom could represent a life-threatening emergency, call 911 or go to an emergency department. 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.
Cosmetic Surgery Costs and Canadian Health Coverage
When a procedure is intended only to improve appearance, public health insurance in Canada will usually not cover it. Out-of-pocket expenses may include the surgeon, anesthesia provider, operating room, medical devices, recovery clothing, prescriptions, laboratory work, and follow-up items.
The financial responsibility for postoperative problems should be clarified in advance. Whether care is publicly covered can depend on the treatment needed, where it is delivered, and the rules of the patient's province or territory. Travel, accommodation, nursing assistance, missed work, child care, and revision surgery can create additional expenses.
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.
Evaluating the Advantages and Risks of Cosmetic Surgery
A sound decision about cosmetic surgery requires realistic expectations, appropriate health, informed consent, and knowledge of the healing process. A suitable patient recognizes that improvement is possible, but perfection is not.
Take time to compare the expected benefit with the medical, emotional, practical, and financial risks. The decision should account for recovery restrictions, permanent scarring, employment absence, and the possibility that the final result may fall short of expectations.
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.
Making an Informed Decision
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.
Learn about the procedure, review your personal risk factors, confirm the surgeon's qualifications, ask detailed questions, and plan for a full recovery. A complete understanding of the likely improvements, procedure limitations, available options, and associated risks helps patients determine whether cosmetic surgery is appropriate for them.
