Cosmetic surgery can enhance the shape, proportion, or appearance of the face and body. It may also help a person feel more comfortable with a feature that has bothered them for years. Cosmetic surgery may offer benefits, but no operation is entirely predictable. 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. Problems can occur because of anesthesia, bleeding, infection, poor healing, an unexpected reaction, or the way the body responds to surgery. Certain complications are short-lived 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. 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 Are the Risks of Cosmetic Surgery?
Cosmetic surgery risks include any unwanted medical, functional, or aesthetic outcome linked to an operation. 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. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. A complication is different. It is an unexpected problem that exceeds routine healing and can require treatment.
Plastic surgery complications may include the following:
- A hematoma, which is a collection of blood, or other excessive bleeding
- Infection at the incision or within deeper tissue
- Fluid buildup, known as a seroma
- Blood clots affecting the legs or lungs
- Delayed wound healing or wound separation
- Visible scarring that may be thick, widened, raised, or irregular
- Nerve-related problems, including numbness or unusual sensation
- Skin, fat, or tissue loss caused by poor blood supply
- Reactions to anesthesia, medications, adhesives, or surgical materials
- Aesthetic concerns such as asymmetry, poor contours, or an unwanted result
- Problems with normal function, including breathing, motion, 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
A degree of discomfort and physical change is expected while the body heals. Patients who understand expected recovery are better able to separate routine symptoms from possible complications.
Pain and Tenderness
The amount of pain experienced depends on both the procedure and the individual. Patients may notice aching, tightness, burning, or tenderness around the treated 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
Inflammation and the movement of fluid into surgical tissues cause swelling. It may hide the initial surgical result for weeks or months. Bruising occurs when small blood vessels leak beneath the skin. Visible bruising and swelling may follow facial surgery, liposuction, breast procedures, or body contouring.
Patients should not judge the final result too early. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Changes in Feeling After Surgery
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. Nerve recovery often improves sensation over time, but normal feeling may not return completely. Permanent sensory changes are possible.
Short-Term Activity Restrictions
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. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored.
Surgical and Medical Complications
Postoperative Bleeding and Hematoma
Minor bleeding near a surgical incision can occur during early recovery. When bleeding is more substantial, blood may collect under the skin or in the surgical site and form a hematoma. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
Some hematomas can be observed, while others must be drained. Some hematomas require another operation to control the bleeding and remove collected blood.
Surgical Infection
Infection may affect the skin, surgical cut, deeper tissue, or the area surrounding an implant. Possible signs include increasing redness, warmth, swelling, pus-like drainage, worsening pain, fever, chills, or an unpleasant 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. Infection risk and treatment difficulty may increase with smoking, poorly controlled diabetes, inadequate nutrition, or reduced circulation.
Seroma
A seroma develops when a pocket of clear fluid forms under the surgical tissues. 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. Larger ones may need to be drained, sometimes more than once. 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 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. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable.
Problems With Incision Healing
A surgical wound may take longer than expected to close or may start to open. 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. Secondary intention healing allows an open wound to fill and close naturally from the bottom upward. Healing in this way often takes more time and can result in a more noticeable scar.
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. This complication can occur after procedures that lift, tighten, or reposition large sections of tissue. Smoking, vaping, and other nicotine use can greatly increase risk by narrowing blood vessels and reducing tissue oxygen.
The extent of tissue damage determines which treatment is required. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery.
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:
- Feeling sick or vomiting after anesthesia
- Light-headedness, confusion, or extended sleepiness
- Throat discomfort or headache
- Allergic or medication reactions
- Abnormal blood pressure or irregular heart rhythm
- Respiratory difficulty
- Stomach contents entering the lungs, known as aspiration
- Dental, lip, or airway damage
- Serious heart, lung, or neurological complications
Patients must provide complete information about prescriptions, non-prescription drugs, vitamins, supplements, cannabis, alcohol, nicotine, allergies, earlier anesthesia problems, and medical conditions before surgery. The safety of the operation can be reduced when important health information is omitted.
Scarring and Changes to the Skin
Any procedure that cuts the skin creates a scar. 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 and Keloid Scarring
A hypertrophic scar becomes thick or raised but stays within the original wound. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. A history of hypertrophic scars or keloids, whether personal or familial, should be discussed before an operation.
Treatment options can include silicone sheets or gels, pressure treatment, corticocopyright injections, laser therapy, and scar revision. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return.
Skin Colour and Texture Changes
The treated skin may develop colour changes, redness, noticeable blood vessels, dimpling, firmness, or textural differences. These effects may be temporary or permanent. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
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.
Possible aesthetic concerns include:
- Persistent asymmetry
- Visible dents, bulges, or contour differences
- Under-correction or over-correction
- A result that appears unnatural or excessively tight
- 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
- Dissatisfaction despite an acceptable medical result
Before-and-after images, photographs, and computer simulations may help explain possibilities, but they do not promise a matching result. 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. However, another operation brings new risks. A second operation may be technically harder because previous surgery can leave scar tissue, stiffness, and diminished blood flow.
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.
Risks Associated With Specific Cosmetic Procedures
Although many operations share common complications, every cosmetic procedure has its own specific risks.
Facelift and Neck Lift Risks
Possible problems after a facelift or neck lift include cosmetic plastic surgeons near me 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. Because nicotine restricts circulation, its use can greatly increase wound and skin-healing complications.
Risks of Nose Surgery
Rhinoplasty may cause ongoing swelling, nosebleeds, infection, asymmetry, changes in smell, visible contour irregularities, septal perforation, nasal collapse, or difficulty breathing through the nose. The final shape may take a year or longer to become clear. A revision nose operation is often more challenging because the first surgery changes the cartilage and creates internal scarring.
Blepharoplasty 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. A patient should seek urgent care if severe eye pain or an abrupt change in vision occurs.
Breast Surgery Risks
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.
Breast implants bring added long-term considerations. 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.
Possible Liposuction Complications
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. Removing larger volumes of fat or treating several body areas may increase medical stress and recovery demands.
Possible Tummy Tuck and Body Lift Complications
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. Possible complications include fluid buildup, DVT, infection, tissue loss, incision opening, reduced sensation, visible scars, and changes in navel shape or placement. Patients may need several weeks of movement restrictions.
Possible Fat Grafting Complications
During fat grafting, fat is taken from one body area and placed into a different location. Because a portion of the injected fat may not survive, the final fullness and balance can change. 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.
Who May Face Greater Cosmetic Surgery Risks?
Some health and lifestyle factors can raise the chance of complications. Before proceeding, some patients require tests, adjustments to treatment, weight changes, nicotine cessation, or approval from another medical professional.
Factors associated with higher surgical risk include:
- Exposure to nicotine through smoking, vaping, gum, patches, or other products
- Diabetes with unstable or elevated blood sugar
- Cardiac, respiratory, renal, liver, or vascular conditions
- A clotting or bleeding condition, or previous blood clots
- Obesity, unstable weight, or recent major weight loss or gain
- A diagnosed or suspected sleep-related breathing disorder
- Immune disorders or reduced immune function
- Nutritional deficiencies or a low red blood cell count
- Previous radiation or surgery in the treatment area
- Prescription products, non-prescription medicines, or supplements that alter bleeding and healing
- Expectations that cannot be achieved or unaddressed psychological concerns affecting consent
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.
Psychological Effects of Cosmetic Surgery
The effects of cosmetic surgery may be psychological and emotional, not only physical. 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.
When a patient's expectations exceed the realistic limits of surgery, deeper or longer-lasting disappointment may follow. Although surgery can alter appearance, it cannot promise self-confidence, fix relationships, ensure professional success, or resolve wider life difficulties.
The patient's motivation for considering surgery should be discussed during an appropriate assessment. 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. 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.
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.
- 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.
- Provide a complete medical history, including medications, supplements, nicotine, cannabis, alcohol, allergies, and prior operations.
- 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.
- Do not schedule travel, work duties, exercise, or major events until you understand how long recovery may take.
- 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.
Choosing a Cosmetic Surgeon in Canada
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.
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 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 low-frequency, high-impact risks should I know about?
- Which medical professional will administer and monitor my anesthesia?
- What happens if I have a complication after business hours?
- Which hospital or emergency facility would treat me if a serious problem occurred?
- 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. 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. Any complication that could significantly affect the patient's medical condition, employment, lifestyle, or priorities should receive special attention.
Patients should have enough time to review consent information without being pressured. 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.
Warning Signs After Cosmetic Surgery
The surgeon's office should explain which symptoms require attention and copyright the appropriate provider. Unexpected or worsening symptoms that fall outside the recovery instructions should be reported without delay.
Potential emergency signs after cosmetic surgery include:
- Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness
- Unexpected pain, swelling, redness, or heat affecting one leg
- Significant bleeding or swelling that expands quickly
- Pain that remains severe despite the prescribed treatment plan
- High fever, chills, spreading redness, or pus-like drainage
- Mental confusion, severe weakness, or unusual inability to remain alert
- 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
- Any symptom the surgical team identified as an emergency
Call 911 or seek emergency care when symptoms may be life-threatening. Do not wait for an office to reopen when there is severe breathing trouble, chest pain, loss of consciousness, major bleeding, or another urgent concern.
Financial Considerations for Cosmetic Surgery in Canada
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.
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.
Patients considering medical tourism should think about who will provide follow-up care after returning to Canada. 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. 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.
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. This is an important part of responsible care.
Making an Informed Decision
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.
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.
