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. A careful decision about cosmetic surgery should include a clear understanding of its possible risks.
Most patients recover without a major complication, but no surgeon can promise a perfect result or a risk-free operation. 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. 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. 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.
Understanding 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.
It is normal for patients to experience some minor effects after many operations. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. A complication is different. A complication extends beyond normal recovery and may need medical care.
Plastic surgery complications may include the following:
- Bleeding or the development of a blood collection known as a hematoma
- Incision-site or deep-tissue infection
- Fluid buildup, known as a seroma
- Blood clots in the legs or lungs
- Slow wound healing or separation of the incision
- Visible scarring that may be thick, widened, raised, or irregular
- Nerve-related problems, including numbness or unusual sensation
- Loss of skin, fat, or other tissue because of reduced circulation
- 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
- The need for additional treatment or revision surgery
Major complications do not happen often, but patients should understand that they remain possible. Possible rare complications include severe infection, major hemorrhage, organ damage, heart problems, stroke, a blood clot in the lungs, permanent impairment, and death.
Expected Short-Term Effects of Cosmetic Surgery
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.
Soreness After Cosmetic Surgery
Each patient experiences pain differently, and some operations cause more discomfort than others. Tightness, aching, burning, or tenderness may occur near the surgical area. Discomfort is normally expected to improve gradually during healing. Patients should quickly report severe or spreading pain, especially when it is accompanied by fever, redness, shortness of breath, or unusual swelling.
Postoperative 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. Small blood vessels can release blood under the skin, creating bruising. Patients undergoing face surgery, breast surgery, liposuction, or body contouring may experience noticeable bruising and swelling.
Patients should not judge the final result too early. Residual swelling can change shape, symmetry, and skin texture during recovery.
Altered Sensation and Numbness
Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. 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.
Temporary Limits on Activity
Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. 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.
Surgical and Medical Complications
Bleeding and Hematoma
Minor bleeding near a surgical incision can occur during early recovery. More significant bleeding can form a hematoma, which is a collection of blood beneath the skin or inside the surgical area. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a 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
The incision, nearby skin, deeper surgical tissues, or an implant pocket can become infected. An infection may cause increasing warmth, redness, swelling, pain, discharge resembling pus, fever, chills, or a bad smell.
Treatment may involve antibiotics, wound care, drainage, or another operation. An infected breast implant or other medical device may need to be removed. Patients who smoke or have uncontrolled diabetes, nutritional problems, or poor blood flow may face a higher infection risk and slower recovery.
Seroma
A seroma develops when a pocket of clear fluid forms under the surgical tissues. It is more common after procedures that create a large space beneath the tissue, such as tummy tuck surgery, body lift surgery, breast surgery, or extensive liposuction.
A minor fluid collection can sometimes disappear as the body reabsorbs it. 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.
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. If part of the clot travels to the lungs, it can cause a pulmonary embolism. This is a medical emergency.
Factors that may raise blood clot risk include lengthy surgery, reduced mobility, a history of clots, particular medications, nicotine exposure, obesity, certain illnesses, and multiple procedures performed together. Depending on the patient, preventive steps may involve getting up early, using compression equipment or garments, staying hydrated, or taking prescribed blood thinners.
Poor Wound Healing
An incision may heal slowly or begin to separate. Healing may be impaired by poor circulation, infection, pressure on the incision, nicotine, some medicines, or underlying health conditions.
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.
Skin or Tissue Necrosis
Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and die. Operations that move, tighten, or lift broad areas of tissue can carry a risk of necrosis. Smoking, vaping, and other nicotine use can greatly increase risk by narrowing blood vessels and reducing tissue oxygen.
Management of necrosis varies according to the size and depth of the affected area. 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
Depending on the operation, cosmetic surgery can involve local anesthetic, sedating medication, general anesthesia, or multiple methods together. The most suitable anesthesia plan is based on the type of surgery, patient health history, procedure duration, and location where surgery takes place.
Possible anesthesia-related problems include:
- Feeling sick or vomiting after anesthesia
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- Throat discomfort or headache
- An allergic response or adverse drug reaction
- Abnormal blood pressure or irregular heart rhythm
- Breathing difficulties
- Aspiration of stomach contents into the lungs
- 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.
Scarring and Changes to the Skin
A surgical procedure that breaks the skin will always leave some degree of scarring. 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. They may soften and fade over 12 months or longer. The final appearance depends on genetics, skin type, incision tension, infection, sun exposure, wound care, location, and the type of operation.
Hypertrophic Scars and Keloids
A scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. 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. Scar treatment may improve texture and appearance, but it cannot ensure that a hypertrophic scar or keloid will never come back.
Pigment and Texture Irregularities
Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. These effects may be temporary or permanent. The risk can differ by skin tone and by the type of procedure performed.
Aesthetic Risks and Unsatisfactory Results
A technically successful operation does not always produce the appearance a patient expected. The body's response is shaped by age, anatomy, skin quality, earlier surgery, scar development, and normal side-to-side differences.
Potential cosmetic outcome concerns include:
- Persistent asymmetry
- Visible dents, bulges, or contour differences
- A result that is under-treated or over-treated
- An artificial-looking or over-tightened outcome
- A changing contour as postoperative swelling decreases
- Implant position problems
- Visible or poorly placed scars
- Recurrence of sagging or tissue laxity over time
- Disappointment with an outcome that falls within an acceptable surgical range
Photos, digital simulations, and before-and-after galleries can support discussion, but they cannot guarantee an identical outcome. Every patient's tissues, proportions, and recovery process are unique.
Corrective and Revision Surgery
When problems occur or the outcome may benefit from improvement, revision cosmetic surgery can be considered. Revision surgery carries risks of its own. Because scarred tissues may be less flexible and have reduced circulation, revision procedures can be more difficult.
It is important to ask how the practice handles revisions and which expenses are covered. 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
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Possible Facelift and Neck Lift Complications
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. Because nicotine restricts circulation, its use can greatly increase wound and skin-healing complications.
Possible Rhinoplasty Complications
Rhinoplasty may cause ongoing swelling, nosebleeds, infection, asymmetry, changes in smell, visible contour irregularities, septal perforation, nasal collapse, or difficulty breathing through the nose. A rhinoplasty result may not fully settle for 12 months or more. Scar formation and altered cartilage can make secondary rhinoplasty more complex.
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. 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.
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. Implants are not lifetime devices. Health Canada also provides safety information about uncommon conditions linked with certain breast implants, including breast implant-associated anaplastic large cell lymphoma.
Liposuction Risks
Liposuction may lead to dents, surface irregularities, skin looseness, fluid problems, numbness, fluid collection, infection, organ injury, fat embolism, or lidocaine toxicity when local anesthesia is involved. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated.
Possible Tummy Tuck and Body Lift Complications
Large sections of skin and underlying tissue are moved during abdominoplasty and body lift surgery. Possible complications include fluid buildup, DVT, infection, tissue loss, incision opening, reduced sensation, visible scars, and changes in navel shape or placement. Recovery may involve several weeks of limited movement and physical activity.
Fat Grafting Risks
Fat transfer involves removing fat from one area and injecting it into another. 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. Fat transfer risks vary according to whether the treatment area is the face, breast, buttocks, or another body region.
Factors That Increase the Risk of Complications
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
- Poorly controlled diabetes
- Cardiac, respiratory, renal, liver, or vascular conditions
- Past DVT, pulmonary embolism, or a diagnosed bleeding disorder
- A high body mass index or significant changes in weight
- Sleep apnea
- Immune disorders or reduced immune function
- Nutritional deficiencies or a low red blood cell count
- Scar tissue or circulation changes from prior operations or radiation
- Drugs, vitamins, or supplements that interfere with clotting or tissue repair
- Mental health concerns or unrealistic goals that interfere with informed decision-making
Having a risk factor does not always mean surgery is impossible. It means the surgeon must decide whether the procedure can be performed safely and whether changes are needed before proceeding.
Emotional and Mental Health Considerations
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. A short period of sadness or emotional difficulty after surgery is sometimes known as postoperative blues.
More serious dissatisfaction can occur when expectations do not match what surgery can realistically achieve. A cosmetic procedure can modify the body, but it does not guarantee emotional confidence, relationship improvement, career advancement, or solutions to unrelated personal concerns.
A responsible assessment should explore the patient's reasons for seeking surgery. Concerns may arise when someone is being pressured, remains unhappy after repeated procedures, is intensely focused on a small flaw, or expects surgery to change every part of life.
Body dysmorphic disorder is a mental health condition involving intense distress about perceived appearance flaws. Surgery may not relieve the underlying concern. A psychological evaluation or professional support may be recommended before surgery when concerns are identified.
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.
- Follow instructions about fasting, medication changes, testing, and stopping nicotine.
- 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.
- Attend all follow-up appointments and report unusual symptoms promptly.
- Your recovery should not be compared with social media images, promotional content, or another person's timeline.
- Do not make an early decision about revision, because the tissues may require many months to heal and stabilize.
Choosing a Cosmetic Surgeon in Canada
Medical regulation in Canada is handled at the provincial and territorial level. The public directory of the appropriate college of physicians and surgeons can be used to check licensing, specialty registration, and listed practice details.
Another useful question is whether the doctor holds plastic surgery certification from the Royal College of Physicians and Surgeons of Canada. Certification is one useful qualification to review, but patients should also consider experience with the specific procedure, complication management, communication, surgical setting, and follow-up care.
During the consultation, patients may wish to ask:
- What are your surgical qualifications and specialty credentials?
- How frequently is this specific procedure performed in your practice?
- Am I a suitable candidate based on my health and anatomy?
- Which problems do your patients experience most often after this operation?
- What low-frequency, high-impact risks should I know about?
- Who will provide anesthesia?
- What happens if I have a complication after business hours?
- Where would I receive emergency care if needed?
- How many postoperative appointments are provided as part of the surgical plan?
- What costs could arise if I need treatment or revision surgery?
What Informed Consent Should Include
Signing paperwork alone does not create true informed consent. It should be a continuing conversation that allows the patient to decide freely after receiving adequate information.
A proper consent discussion includes the procedure itself, expected improvement, significant complications, alternative options, recovery requirements, limitations, and the choice to decline treatment. 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. Questions should be asked whenever risks, terminology, or instructions are not fully understood. Taking notes, involving a support person, and reviewing written material outside the clinic can support an informed decision.
Warning Signs After Cosmetic Surgery
Your surgical team should provide specific instructions about when and how to seek help. Contact the clinic promptly when symptoms are unexpected, worsening, or different from the recovery plan.
Urgent warning signs may 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
- Severe pain that is not controlled by prescribed medication
- A significant fever, shaking chills, expanding redness, or thick discharge
- Mental confusion, severe weakness, or unusual inability to remain alert
- 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 symptom the surgical team identified as an emergency
When a symptom could represent a life-threatening emergency, call 911 or go to an emergency department. 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.
Financial Risks and Health Coverage 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.
The financial responsibility for postoperative problems should be clarified in advance. Health coverage for complications varies based on medical necessity, treatment setting, and the applicable provincial or territorial insurance plan. Travel, accommodation, nursing assistance, missed work, child care, and revision surgery can create additional expenses.
Medical tourists need to determine which Canadian provider, if any, will manage recovery and complications after their return. Lower upfront fees may become more expensive if postoperative infection, wound breakdown, clotting, implant complications, or revision treatment is required.
Evaluating the Advantages and Risks of Cosmetic Surgery
Patients should consider surgery only when their goals are achievable, their health is suitable, and they understand the risks and recovery. Realistic patients seek meaningful improvement while accepting that no procedure can deliver a flawless result.
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. Recommending against surgery can be a sign of careful and ethical medical practice.
How to Make an Informed Cosmetic Surgery 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.
Before surgery, research the operation, assess your health risks, verify medical credentials, ask thorough questions, and prepare for the complete healing period. A complete understanding of minimally invasive plastic surgery the likely improvements, procedure limitations, available options, and associated risks helps patients determine whether cosmetic surgery is appropriate for them.
