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. Cosmetic surgery may offer benefits, but no operation is entirely predictable. Understanding the risks of cosmetic surgery is an essential part of deciding whether a procedure is right for you.
Most patients recover without a major complication, but no surgeon can promise a perfect result or a risk-free operation. 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. More serious problems may call for medication, hospital treatment, revision surgery, or ongoing medical follow-up.
Patients in Canada should receive clear information about the expected benefits, material risks, alternatives, recovery requirements, and possible consequences of not having treatment. During a careful consultation, patients should be able to consider the facts without being rushed. Cosmetic surgery is usually elective, so you should feel comfortable delaying or declining it when the risks outweigh the likely benefits.
Understanding the Risks of Cosmetic Surgery
Any undesirable medical, functional, or cosmetic result connected with an operation may be considered a cosmetic surgery risk. Risk levels vary according to the procedure, surgical method, treatment area, operation length, anesthesia type, and the patient's general health.
Minor side effects are expected after many procedures. 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:
- Bleeding or a collection of blood called a hematoma
- Incision-site or deep-tissue infection
- Seroma formation, which involves fluid collecting beneath the tissue
- Clots that form in a leg vein or travel to the lungs
- An incision that heals poorly, slowly, or begins to open
- Scars that become prominent, raised, wide, or uneven
- Damage to nerves, loss of feeling, or changes in sensation
- Tissue damage or loss resulting from inadequate blood flow
- Reactions to anesthesia, medications, adhesives, or surgical materials
- Asymmetry, contour problems, or an unwanted appearance
- Functional changes affecting breathing, movement, or feeling
- Additional medical treatment or a revision operation
Serious complications are uncommon, but they are still important to discuss. Possible rare complications include severe infection, major hemorrhage, organ damage, heart problems, stroke, a blood clot in the lungs, permanent impairment, and death.
Common Early Effects During Cosmetic Surgery Recovery
Some discomfort and physical change are part of normal healing. Knowing what normal healing looks like helps patients recognize when a symptom may be a warning sign.
Pain and Tenderness
Pain levels vary by procedure and patient. Tightness, aching, burning, or tenderness may occur near the surgical area. 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.
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. Bruises form when tiny blood vessels are damaged and blood collects beneath the skin. Facial procedures, liposuction, breast surgery, and body contouring can all cause visible swelling and bruising.
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. Nerve recovery often improves sensation over time, but normal feeling may not return completely. In some cases, changes in sensation may be permanent.
Activity Limitations During Recovery
Patients may need help with transportation, meals, child care, pet care, household work, and personal tasks. Patients may be temporarily unable to drive, exercise, lift heavy objects, swim, or resume their jobs. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored.
Medical and Surgical Risks
Postoperative Bleeding and Hematoma
A limited amount of bleeding around the incision may be expected. When bleeding is more substantial, blood may collect under the skin or in the surgical site and form a hematoma. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
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.
Surgical Infection
An infection can develop in the skin, incision, tissue, or around an medical aesthetics implant. An infection may cause increasing warmth, redness, swelling, pain, discharge resembling pus, fever, chills, or a bad smell.
An infection can require medication, incision care, removal of fluid, or an additional procedure. 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.
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.
The body may gradually absorb a small seroma without further treatment. A larger seroma may require drainage on one or several occasions. A persistent seroma can create pressure, interfere with wound healing, and increase the chance of infection.
Blood Clots and Pulmonary Embolism
Deep vein thrombosis, known as DVT, develops when a clot forms in one of the body's deep veins, usually in a leg. A pulmonary embolism can occur if a piece of the clot breaks away and reaches the lungs. This complication can be life-threatening and must be treated urgently.
Long procedures, inactivity, earlier blood clots, some drugs, nicotine use, excess body weight, health conditions, and combined operations can increase the chance of DVT or pulmonary embolism. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate.
Poor Wound Healing
Slow healing or separation of the incision can occur after cosmetic surgery. 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. Secondary intention healing allows an open wound to fill and close naturally from the bottom upward. This process can take longer and may leave a more visible scar.
Tissue Necrosis
Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to die. Operations that move, tighten, or lift broad areas of tissue can carry a risk of necrosis. 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. Possible treatment includes wound management, removal of dead tissue, a skin graft, reconstructive surgery, or revision at a later date.
Anesthesia Risks in Cosmetic Surgery
Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. The safest choice depends on the operation, the patient's medical history, the expected length of surgery, and the surgical setting.
Possible anesthesia-related problems include:
- Postoperative nausea or vomiting
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- Headache or sore throat
- An allergic response or adverse drug reaction
- Fluctuations in blood pressure or disturbances in heartbeat
- Problems with breathing
- Stomach contents entering the lungs, known as aspiration
- Damage to teeth, lips, or the airway
- 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. 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.
Early scars can be firm, raised, reddish, or more deeply coloured before they mature. 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.
Hypertrophic Scars and Keloids
A scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. A keloid grows beyond the borders of the incision. People with a personal or family history of abnormal scarring should tell their surgeon before surgery.
Possible treatments include silicone products, pressure therapy, copyright injections, laser treatment, or scar revision. Although treatment can make a scar less noticeable, recurrence of abnormal tissue remains possible.
Changes in Skin Colour and Texture
Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin texture. Some of these changes resolve over time, while others can last permanently. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
The Risk of an Unwanted Cosmetic Result
A procedure can be medically and technically successful while still producing a result the patient did not anticipate. Healing is affected by anatomy, skin elasticity, age, previous surgery, scar formation, and natural differences between the two sides of the body.
Appearance-related problems may include:
- Ongoing asymmetry
- Uneven contours or visible irregularities
- A result that is under-treated or over-treated
- A result that appears unnatural or excessively tight
- A changing contour as postoperative swelling decreases
- Movement or poor positioning of an implant
- Noticeable scars or scars in an unfavourable location
- Gradual recurrence of skin or tissue laxity
- Patient dissatisfaction even when the result is medically acceptable
Photos, digital simulations, and before-and-after galleries can support discussion, but they cannot guarantee an identical outcome. Each patient has different anatomy and heals in a different way.
Revision Cosmetic Surgery
A corrective operation may be discussed if a complication develops or if the original result could be refined. A second procedure introduces another set of surgical risks. Scar tissue can make the procedure more complex, and the tissues may have less blood supply or flexibility than they did before the first surgery.
Before proceeding, patients should understand exactly what is included in the surgeon's or clinic's revision policy. 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.
Possible Facelift and Neck Lift Complications
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
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
Blepharoplasty risks include dry or irritated eyes, temporary blurred vision, difficulty closing the eyelids, eyelid malposition, asymmetry, scarring, bleeding behind the eye, and changes in vision. 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. Other risks include hematoma, infection, fat necrosis, delayed healing, and changes in nipple or areola position.
Patients with breast implants face additional concerns that can develop over time. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. Breast implants are not designed to last for an entire lifetime. Health Canada also provides safety information about uncommon conditions linked with certain breast implants, including breast implant-associated anaplastic large cell lymphoma.
Risks of Liposuction
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.
Risks of Abdominoplasty and Body Lift Surgery
Tummy tuck and body lift procedures require long incisions and repositioning of broad tissue areas. 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 uses liposuction to collect fat, which is then injected into another part of the face or body. The body naturally absorbs some transferred fat, potentially reducing volume or creating asymmetry. Additional complications include dead fat tissue, cysts, calcification, infection, oil cysts, and fat entering a blood vessel. The location where fat is injected, such as the face, breasts, or buttocks, affects the type and seriousness of potential complications.
Who May Face Greater Cosmetic Surgery Risks?
A patient's health status and daily habits may make complications more likely. A patient may need medical testing, treatment changes, weight management, nicotine cessation, or clearance from another health professional before surgery.
The likelihood of complications may increase with:
- Exposure to nicotine through smoking, vaping, gum, patches, or other products
- Diabetes with unstable or elevated blood sugar
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A clotting or bleeding condition, or previous blood clots
- Obesity or major weight changes
- A diagnosed or suspected sleep-related breathing disorder
- Immune system disorders
- Inadequate nutrition or serious anemia
- Earlier surgery or radiation therapy involving the same area
- Medications or supplements that affect bleeding or healing
- Unrealistic expectations or untreated mental health concerns that affect decision-making
A higher-risk medical history does not necessarily make an operation unsuitable. The surgeon needs to evaluate the level of risk and decide whether health or lifestyle changes are necessary before treatment.
Emotional and Mental Health Considerations
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. A short period of sadness or emotional difficulty after surgery is sometimes known as 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. 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. 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.
How to Reduce the Risks of Cosmetic Surgery
Cosmetic surgery always carries some risk, yet careful planning can reduce the likelihood of complications.
- Choose a properly qualified physician with training and experience relevant to the procedure.
- Check the doctor's licence, registration, and professional standing with the applicable provincial or territorial medical regulator.
- Ask where the procedure will be performed and what safety, emergency, and infection-control systems are available.
- Disclose your entire health history, including previous surgery, allergies, medications, supplements, alcohol, cannabis, and nicotine use.
- 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.
- 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.
- Avoid judging your recovery against filtered photographs or the healing experience of someone else.
- Wait until healing is mature before deciding whether revision surgery is needed.
Finding a Qualified Canadian Cosmetic Surgeon
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.
Patients may also ask whether a surgeon is certified in plastic surgery by the Royal College of Physicians and Surgeons of Canada. Royal College certification is valuable, but it should be considered alongside relevant experience, patient communication, emergency planning, surgical environment, and postoperative support.
Questions to ask during a cosmetic surgery consultation include:
- What training and certification do you have?
- How many times have you carried out this operation?
- Based on my health, goals, and anatomy, is this procedure suitable for me?
- What complications are seen most frequently with this procedure in your practice?
- What low-frequency, high-impact risks should I know about?
- Who is responsible for anesthesia care during the operation?
- How can I obtain care if a problem develops at night or on a weekend?
- Where would I receive emergency care if needed?
- What follow-up visits are included?
- Which additional expenses would I be responsible for if a complication or revision occurs?
Informed Consent for Cosmetic Surgery
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.
A proper consent discussion includes the procedure itself, expected improvement, significant complications, alternative options, recovery requirements, limitations, and the choice to decline treatment. Risks that are especially relevant to the patient's health, job, lifestyle, or personal priorities should also be discussed.
No one should be pushed into signing a surgical consent form quickly. Questions should be asked whenever risks, terminology, or instructions are not fully understood. It can be helpful to take notes, bring a trusted person to the consultation, and review written instructions at home.
Postoperative Warning Signs
The surgeon's office should explain which symptoms require attention and copyright the appropriate provider. Contact the clinic promptly when symptoms are unexpected, worsening, or different from the recovery plan.
Symptoms that may require urgent care include:
- Chest pain, shortness of breath, coughing blood, or fainting
- One-sided leg swelling, tenderness, warmth, or discolouration
- Significant bleeding or swelling that expands quickly
- Severe pain that is not controlled by prescribed medication
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Confusion, extreme weakness, or difficulty staying awake
- Skin that becomes very pale, dark, blistered, or cold to the touch
- Sudden vision loss, severe eye pain, or major visual changes
- Persistent vomiting that prevents normal hydration
- Any problem your surgeon specifically described as requiring emergency care
Emergency medical services should be contacted immediately for potentially life-threatening complications. Severe breathing difficulty, chest pain, unconsciousness, heavy bleeding, and other emergency symptoms should not wait until normal clinic hours.
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. The patient is normally responsible for surgeon fees, anesthetic services, facility charges, implants, compression garments, medication, tests, and associated costs.
Complication-related costs should be discussed before surgery. Coverage may depend on the medical service required, the location where treatment is provided, and the patient's provincial or territorial plan. Patients should budget for possible travel, lodging, caregiving, time away from employment, child care, and future revision surgery.
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.
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. 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. 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. This is an important part of responsible care.
Making an Informed Decision
Learning about cosmetic surgery risks does not mean expecting that something will go wrong. 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. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
