Cosmetic surgery can enhance the shape, proportion, or appearance of the face and body. For some people, it can also reduce concern about a physical feature that has caused distress for years. Even so, all operations involve some uncertainty. Before deciding whether a procedure is suitable, it is essential to understand the risks of cosmetic surgery.
Most patients recover without a major complication, but no surgeon can promise a perfect result or a risk-free operation. Problems can occur because of anesthesia, bleeding, infection, poor healing, an unexpected reaction, or the way the body responds to surgery. Some complications are temporary and easy to treat. In other cases, a complication can require drugs, hospital care, another operation, or extended monitoring.
Canadian patients should receive understandable information about benefits, material risks, available alternatives, recovery demands, and the possible effects of choosing no treatment. A thorough consultation should provide enough time to review the information and make a decision without pressure. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits.
What Risks Can Cosmetic Surgery Involve?
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.
Minor side effects are expected after many procedures. During early recovery, swelling, bruising, tenderness, numbness, tightness, tiredness, and light drainage may be normal. A true complication is not the same as an expected side effect. A complication extends beyond normal recovery and may need medical care.
Potential problems associated with plastic surgery include:
- A hematoma, which is a collection of blood, or other excessive bleeding
- Infection at the incision or within deeper tissue
- A collection of fluid called a seroma
- Blood clots affecting the legs or lungs
- An incision that heals poorly, slowly, or begins to open
- Scars that become prominent, raised, wide, or uneven
- Nerve injury, numbness, or altered sensation
- Skin, fat, or tissue loss caused by poor blood supply
- Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials
- Asymmetry, contour problems, or an unwanted appearance
- Changes in function, such as breathing, movement, or sensation
- Additional medical treatment or a revision operation
Although serious complications are rare, they must still be reviewed before surgery. Rare risks may include severe infection, major blood loss, organ injury, heart problems, stroke, pulmonary embolism, permanent disability, or death.
Expected Short-Term Effects of Cosmetic Surgery
Some discomfort and physical change are part of normal healing. Patients should understand what is expected so they can tell the difference between routine recovery and a warning sign.
Soreness After Cosmetic Surgery
Pain levels vary by procedure and patient. Patients may notice aching, tightness, burning, or tenderness around the treated area. Pain should usually become easier to manage as healing continues. Pain that suddenly becomes severe, spreads, or occurs with fever, redness, shortness of breath, or unusual swelling should be reported promptly.
Bruising and Tissue Swelling
Inflammation and the movement of fluid into surgical tissues cause swelling. For several weeks or even months, swelling may conceal the true result of surgery. Bruises form when tiny blood vessels are damaged and blood collects beneath the skin. Patients undergoing face surgery, breast surgery, liposuction, or body contouring may experience noticeable bruising and swelling.
The outcome of surgery should not be assessed before healing has progressed. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Changes in Feeling After Surgery
During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Temporary changes such as tingling, numbness, tenderness, or reduced sensation may occur after surgery. Nerve recovery often improves sensation over time, but normal feeling may not return completely. 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
Postoperative Bleeding and Hematoma
A limited amount of bleeding around the incision may be expected. More significant bleeding can form a hematoma, which is a collection of blood beneath the skin or inside the surgical area. Possible signs of a hematoma include worsening pain, hard swelling, colour changes, or sudden asymmetry.
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. 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. Removal can be required when infection develops around a breast implant or surgical device. Patients who smoke or have uncontrolled diabetes, nutritional problems, or poor blood flow may face a higher infection risk and slower recovery.
Postoperative Seroma
Clear fluid that gathers beneath the skin is known as a seroma. 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.
The body may gradually absorb a small seroma without further treatment. Repeated drainage may be necessary when a significant seroma develops. 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. 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. Depending on the patient, preventive steps may involve getting up early, using compression equipment or garments, staying hydrated, or taking prescribed blood thinners.
Problems With Incision Healing
An incision may heal slowly or begin to separate. Factors such as reduced blood flow, infection, wound tension, nicotine use, medications, and illness may prevent normal 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. Healing in this way often takes more time and can result in a more noticeable scar.
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. Smoking and nicotine use are major preventable risk factors because nicotine narrows blood vessels and reduces oxygen delivery.
Treatment depends on the amount of tissue affected. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery.
Risks Related to Anesthesia
Depending on the operation, cosmetic surgery can involve local anesthetic, sedating medication, general anesthesia, or multiple methods together. Choosing an anesthesia method requires consideration of the operation, medical background, expected surgical time, and facility.
Anesthesia may be associated with the following risks:
- Postoperative nausea or vomiting
- Dizziness, confusion, or prolonged drowsiness
- Headache or sore throat
- Allergic or medication reactions
- Abnormal blood pressure or irregular heart rhythm
- Problems with breathing
- Stomach contents entering the lungs, known as aspiration
- Damage to teeth, lips, or the airway
- Severe cardiac, respiratory, or neurological problems
A preoperative health history should include every medication, vitamin, supplement, cannabis product, alcohol or nicotine habit, allergy, previous anesthetic reaction, and relevant diagnosis. Leaving out information can make anesthesia and surgery less safe.
Cosmetic Surgery Scars and Skin Changes
Whenever an incision is made through the skin, a scar will form. Surgeons usually place incisions where they can be hidden within natural folds, hairlines, or clothing, but a scar cannot be erased completely.
During the first stages of healing, scars may look red, thick, firm, elevated, or darker than nearby skin. Scars may require a year or more to flatten, soften, and become less noticeable. Genetic factors, skin characteristics, pressure on the incision, infection, sunlight, wound care, surgical location, and procedure type all influence the finished scar.
Hypertrophic Scars and Keloids
Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. 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. Although treatment can make a scar less noticeable, recurrence of abnormal tissue remains possible.
Skin Colour and Texture Changes
Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. These effects may be temporary or permanent. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
Aesthetic Risks and Unsatisfactory Results
A procedure can be medically and technically successful while still producing a result the patient did not anticipate. Individual anatomy, skin flexibility, age, past procedures, scarring, and natural asymmetry all affect healing.
Appearance-related problems may include:
- Persistent asymmetry
- Visible dents, bulges, or contour differences
- Under-correction or over-correction
- A result that appears unnatural or excessively tight
- Changes in shape as swelling settles
- Movement or poor positioning of an implant
- Scarring that is prominent or difficult to conceal
- Recurrence of sagging or tissue laxity over time
- 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. Every patient's tissues, proportions, and recovery process are unique.
The Possibility of Revision Surgery
A corrective operation may be discussed if a complication develops or if the original result could be refined. However, another operation brings new risks. Because scarred tissues may be less flexible and have reduced circulation, revision procedures can be more difficult.
Patients should ask what the clinic's revision policy covers. Surgeon fees, facility costs, anesthesia, implants, medications, travel, and time away from work may not all be included in the original price.
Procedure-Specific Cosmetic Surgery Risks
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Risks of Facelift and Neck Lift Surgery
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. The final shape may take a year or longer to become clear. Scar formation and altered cartilage can make secondary rhinoplasty more complex.
Possible Complications of Eyelid Surgery
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. A patient should seek urgent care if severe eye pain or an abrupt change in vision occurs.
Risks of Cosmetic Breast Surgery
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.
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. 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.
Possible Liposuction Complications
Liposuction may lead to dents, surface irregularities, skin looseness, fluid problems, numbness, fluid collection, infection, organ injury, fat embolism, or lidocaine toxicity when local anesthesia is involved. Removing larger volumes of fat or treating several body areas may increase medical stress and recovery demands.
Tummy Tuck and Body Lift Risks
Large sections of skin and underlying tissue are moved during abdominoplasty and body lift surgery. Risks include seroma, blood clots, infection, skin loss, wound separation, numbness, prominent scarring, and changes to the position or shape of the belly button. 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. Fat grafting may also cause fat necrosis, cyst formation, calcium deposits, infection, oily fluid collections, or unintended injection into circulation. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area.
Who Has a Higher Risk of Complications?
Certain medical conditions and lifestyle habits increase surgical risk. Preoperative preparation may include laboratory testing, medication changes, weight management, stopping nicotine, or obtaining medical clearance.
The likelihood of complications may increase with:
- Cigarette smoking, vaping, or any form of nicotine use
- Poorly controlled diabetes
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A bleeding disorder or history of blood clots
- A high body mass index or significant changes in weight
- A diagnosed or suspected sleep-related breathing disorder
- Conditions affecting the immune system
- Inadequate nutrition or serious anemia
- 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
The presence of one or more risk factors does not automatically prevent cosmetic surgery. 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. 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.
Significant dissatisfaction is more likely when the expected transformation is not medically achievable. 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 causes significant distress and preoccupation with appearance flaws that may seem minor or unnoticeable to others. Surgery may not relieve the underlying concern. In suitable cases, the surgeon may delay treatment and advise the patient to seek mental health assessment or counselling first.
How to Reduce the Risks of Cosmetic Surgery
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.
- Confirm through your province or territory's college of physicians and surgeons that the doctor is licensed and in good standing.
- Ask where the procedure will be performed and what safety, emergency, and infection-control systems are available.
- Provide a complete medical history, including medications, supplements, nicotine, cannabis, alcohol, allergies, and prior operations.
- Complete required testing and obey instructions about fasting, medicines, supplements, smoking, vaping, and other nicotine products.
- When needed, organize transportation and early postoperative support from a responsible adult.
- Understand the recovery timeline before booking work, travel, exercise, or major events.
- 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.
- 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 body contouring cosmetic surgery 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. 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 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?
- What are the most common complications in your practice?
- What rare but serious risks should I understand?
- Who will provide anesthesia?
- What happens if I have a complication after business hours?
- Where would I receive emergency care if needed?
- 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
Informed consent is more than signing a form. It should be a continuing conversation that allows the patient to decide freely after receiving adequate information.
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. The surgeon should also explain risks that may have particular importance because of the patient's occupation, health, daily activities, or individual goals.
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
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.
Symptoms that may require urgent care include:
- Breathing problems, chest discomfort, bloody coughing, or fainting
- Sudden swelling, pain, redness, or warmth in one leg
- 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
- Possible tissue damage shown by abnormal colour, blistering, or low skin temperature
- 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
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.
Cosmetic Surgery Costs and Canadian Health Coverage
Canadian provincial and territorial health plans generally do not pay for operations performed solely for cosmetic reasons. Patients usually pay for the surgeon, anesthesia, operating facility, implants, garments, prescriptions, testing, and other related expenses.
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. Extra costs may arise from transportation, hotels, private nursing, lost income, family care, and corrective procedures.
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
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.
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.
When complications are too likely, benefits are small, or expectations cannot be met safely, an experienced surgeon may recommend against operating. This is an important part of responsible care.
Deciding Whether Cosmetic Surgery Is Right for You
Understanding the risks of cosmetic surgery does not mean assuming that complications will occur. The goal is to make a careful choice based on medical information, not promotional claims, social media influence, or the lowest price.
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.
