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. Cosmetic surgery may offer benefits, but no operation is entirely predictable. Before deciding whether a procedure is suitable, it is essential to understand the risks of cosmetic surgery.
Although most patients heal without serious problems, no surgeon can guarantee perfection or eliminate every surgical risk. Anesthesia, bleeding, infection, healing difficulties, unexpected reactions, and the body's response to an operation can all cause problems. Some problems resolve with simple treatment and do not cause lasting harm. In other cases, a complication can require drugs, hospital care, another operation, or extended monitoring.
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. 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?
Any undesirable medical, functional, or cosmetic result connected with an operation may be considered a cosmetic surgery risk. The procedure being performed, technique used, body area treated, duration of surgery, anesthesia method, and patient health all influence risk.
Minor side effects are expected after many procedures. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. A true complication is not the same as an expected side effect. 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 the development of a blood collection known as a hematoma
- An infection in the incision or deeper surgical tissues
- Fluid buildup, known as a seroma
- Blood clots in the legs or lungs
- Delayed wound healing or wound separation
- Visible scarring that may be thick, widened, raised, or irregular
- Damage to nerves, loss of feeling, or changes in sensation
- Skin, fat, or tissue loss caused by poor blood supply
- Reactions to anesthesia, medications, adhesives, or surgical materials
- Asymmetry, contour problems, or an unwanted appearance
- Problems with normal function, including breathing, motion, or sensation
- A need for further care or corrective surgery
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.
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.
Pain and Tenderness
Each patient experiences pain differently, and some operations cause more discomfort than others. Patients may notice aching, tightness, burning, or tenderness around the treated 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
Swelling is caused by inflammation and fluid moving into the treated tissues. For several weeks or even months, swelling may conceal the true result of surgery. Bruising occurs when small blood vessels leak beneath the skin. 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. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
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. Feeling frequently returns as the nerves heal, although full recovery is aesthetic transformation not certain. There is a possibility that altered feeling will not fully resolve.
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. Failing to follow activity restrictions may raise the risk of bleeding, swelling, wound breakdown, and other problems.
Medical and Surgical Risks
Bleeding and Hematoma
Minor bleeding near a surgical incision can occur during early recovery. Heavier bleeding may create a hematoma, a pocket of blood beneath the skin or within the treated area. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
A small hematoma may only need monitoring, but a larger one 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. If a breast implant or another implanted device becomes infected, removal may be necessary. Patients who smoke or have uncontrolled diabetes, nutritional problems, or poor blood flow may face a higher infection risk and slower recovery.
Seroma
Clear fluid that gathers beneath the skin is known as a seroma. Seromas occur more often after operations that leave a broad space under the tissue, including tummy tuck surgery, body lifts, breast procedures, and extensive liposuction.
Small seromas may resolve as the body absorbs the fluid. 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
Deep vein thrombosis, or DVT, occurs when a blood clot forms in a deep vein, often in the leg. A pulmonary embolism can occur if a piece of the clot breaks away and reaches the lungs. 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. 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
Slow healing or separation of the incision can occur after cosmetic surgery. Healing may be impaired by poor circulation, infection, pressure on the incision, nicotine, some medicines, or underlying health conditions.
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
Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and die. This complication can occur after procedures that lift, tighten, or reposition large sections of tissue. 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. 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:
- Feeling sick or vomiting after anesthesia
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- Throat discomfort or headache
- Unexpected reactions to anesthetic or other medications
- Fluctuations in blood pressure or disturbances in heartbeat
- Problems with breathing
- Stomach contents entering the lungs, known as aspiration
- Dental, lip, or airway damage
- Severe cardiac, respiratory, or neurological problems
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.
Changes in Scarring, Colour, and Skin Texture
A surgical procedure that breaks the skin will always leave some degree of scarring. 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. Scars may require a year or more to flatten, soften, and become less noticeable. How a scar eventually looks is affected by heredity, skin type, wound tension, infection, ultraviolet exposure, aftercare, incision placement, and the operation performed.
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. 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. 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. Alterations in colour or texture may improve, but they can also remain long term. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
Aesthetic Risks and Unsatisfactory Results
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.
Potential cosmetic outcome concerns include:
- Unevenness that remains after healing
- Visible dents, bulges, or contour differences
- A result that is under-treated or over-treated
- An unnatural or overly tight appearance
- A changing contour as postoperative swelling decreases
- Movement or poor positioning of an implant
- Visible or poorly placed scars
- Gradual recurrence of skin or tissue laxity
- Dissatisfaction despite an acceptable medical result
Photos, digital simulations, and before-and-after galleries can support discussion, but they cannot guarantee an identical outcome. Anatomy and healing responses vary from one person to another.
The Possibility of Revision Surgery
A corrective operation may be discussed if a complication develops or if the original result could be refined. 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.
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.
Complications by Type of Cosmetic Surgery
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Facelift and Neck Lift Risks
Possible problems after a facelift or neck lift include bleeding beneath the skin, nerve damage, changes to the hairline, localized hair loss, tissue loss, uneven contours, altered earlobes, numbness, facial weakness, and noticeable scars. Nicotine use can greatly increase the risk of skin-healing problems.
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
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.
Breast Surgery Risks
Breast augmentation, breast lift, and breast reduction may affect nipple sensation, breast symmetry, scar appearance, and the ability to breastfeed. Hematoma, infection, fat necrosis, poor healing, and altered nipple or areola position are also possible.
Patients with breast implants face additional concerns that can develop over time. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. 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.
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. 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
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. Risks include seroma, blood clots, infection, skin loss, wound separation, numbness, prominent scarring, and changes to the position or shape of the belly button. Recovery may involve several weeks of limited movement and physical activity.
Possible Fat Grafting Complications
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. Additional complications include dead fat tissue, cysts, calcification, infection, oil cysts, and fat entering a blood vessel. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area.
Factors That Increase the Risk of Complications
Some health and lifestyle factors can raise the chance of complications. 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
- Cardiac, respiratory, renal, liver, or vascular conditions
- A bleeding disorder or history of blood clots
- Obesity, unstable weight, or recent major weight loss or gain
- Sleep apnea
- Immune system disorders
- Inadequate nutrition or serious anemia
- Scar tissue or circulation changes from prior operations or radiation
- Prescription products, non-prescription medicines, or supplements that alter bleeding and healing
- 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. It means the surgeon must decide whether the procedure can be performed safely and whether changes are needed before proceeding.
Psychological Effects of Cosmetic Surgery
Cosmetic surgery can affect emotional health as well as physical health. Swelling, bruising, fatigue, and temporary lifestyle restrictions may leave some patients feeling worried, frustrated, or low. This temporary low mood is sometimes called postoperative blues.
Significant dissatisfaction is more likely when the expected transformation is not medically achievable. 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. Possible warning signs include outside pressure, ongoing dissatisfaction despite multiple operations, severe concern about a minor feature, and unrealistic beliefs about total life transformation.
Body dysmorphic disorder is a mental health condition involving intense distress about perceived appearance flaws. Changing the physical feature does not necessarily treat the underlying mental health condition. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation.
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.
- Discuss the surgical location, its safety procedures, infection-control practices, and ability to handle emergencies.
- 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.
- Plan for a trusted adult to take you home and help with daily needs after surgery.
- Understand the recovery timeline before booking work, travel, exercise, or major events.
- Attend all follow-up appointments and report unusual symptoms promptly.
- 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.
Finding a Qualified Canadian Cosmetic Surgeon
Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. Patients may verify a physician's licence and registered specialty through the online register maintained by their provincial or territorial regulator.
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.
During the consultation, patients may wish to ask:
- What training and certification do you have?
- How frequently is this specific procedure performed in your practice?
- 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 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?
- Which follow-up visits and services are included in the fee?
- What costs could arise if I need treatment or revision surgery?
Understanding Informed Consent
Informed consent involves more than placing a signature on a document. The process requires clear communication so that the patient can make a knowledgeable and voluntary choice.
The consent process should cover the nature of the procedure, expected benefits, important risks, reasonable alternatives, recovery, limitations, and what could happen without treatment. Risks that are especially relevant to the patient's health, job, lifestyle, or personal priorities should also be discussed.
A patient should never feel rushed to sign. Ask for clarification when a term or complication is unclear. It can be helpful to take notes, bring a trusted person to the consultation, and review written instructions at home.
When to Seek Help 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.
Urgent warning signs may include:
- Chest pain, shortness of breath, coughing blood, or fainting
- Unexpected pain, swelling, redness, or heat affecting one leg
- Uncontrolled bleeding or a sudden increase in swelling
- Pain that remains severe despite the prescribed treatment plan
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Mental confusion, severe weakness, or unusual inability to remain alert
- A pale, dark, blistered, or unusually cold area of skin
- 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
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
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.
Before an operation, patients should ask who pays for treatment if a complication develops. Coverage may depend on the medical service required, the location where treatment is provided, and the patient's provincial or territorial plan. 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. A lower initial price may not include management of infection, wound problems, blood clots, implant complications, or revision surgery.
Evaluating the Advantages and Risks of Cosmetic Surgery
The decision to have cosmetic surgery should be based on realistic goals, good health, informed consent, and a clear understanding of recovery. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection.
Take time to compare the expected benefit with the medical, emotional, practical, and financial risks. Think about your ability to obey postoperative instructions, live with scars, take enough time off, 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. A decision not to operate is sometimes the safest and most responsible form of patient care.
Making an Informed Decision
Being aware of possible complications is not the same as believing they are certain to happen. The goal is to make a careful choice based on medical information, not promotional claims, social media influence, or the lowest price.
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.
