The shape, proportion, or overall appearance of the face and body can be improved through cosmetic surgery. It may also help a person feel more comfortable with a feature that has bothered them for years. Even so, all operations involve some uncertainty. A careful decision about cosmetic surgery should include a clear understanding of its possible risks.
A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. 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.
Canadian patients should receive understandable information about benefits, material risks, available alternatives, recovery demands, and the possible effects of choosing no treatment. A thorough consultation should provide enough time to review the information and make a decision without pressure. 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
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.
Many cosmetic procedures are followed by minor expected side effects. During early recovery, swelling, bruising, tenderness, numbness, tightness, tiredness, and light drainage may be normal. 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
- A collection of fluid called a seroma
- 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
- Nerve injury, numbness, or altered sensation
- Skin, fat, or tissue loss caused by poor blood supply
- Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products
- Aesthetic concerns such as asymmetry, poor contours, or an unwanted result
- Functional changes affecting breathing, movement, or feeling
- The need for additional treatment or revision surgery
Major complications do not happen often, but patients should understand that they remain possible. Rare risks may include severe infection, major blood loss, organ injury, heart problems, stroke, pulmonary embolism, permanent disability, or death.
Common Short-Term Effects After Cosmetic Surgery
Normal recovery often includes temporary discomfort and changes in appearance or sensation. 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. Pain that suddenly becomes severe, spreads, or occurs with fever, redness, shortness of breath, or unusual swelling should be reported promptly.
Bruising and Tissue Swelling
Inflammation and the movement of fluid into surgical tissues cause swelling. It may hide the initial surgical result for weeks or months. Bruising occurs when small blood vessels leak beneath the skin. Facial procedures, liposuction, breast surgery, and body contouring can all cause visible swelling and bruising.
The outcome of surgery should not be assessed before healing has progressed. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Numbness and Changes in Sensation
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. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. In some cases, changes in sensation may be permanent.
Short-Term Activity Restrictions
Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. Restrictions may apply to driving, physical activity, lifting, swimming, and work. Failing to follow activity restrictions may raise the risk of bleeding, swelling, wound breakdown, and other problems.
Potential Surgical Complications
Bleeding or Blood Collection
A limited amount of bleeding around the incision may be expected. More significant bleeding can form a hematoma, which is a collection of blood beneath the skin or inside the surgical area. Possible signs of a hematoma include worsening pain, hard swelling, colour changes, or sudden asymmetry.
Depending on its size and symptoms, a hematoma may be watched or medically drained. In certain cases, the patient may need to return to the operating room.
Surgical Infection
An infection can develop in the skin, incision, tissue, or around an implant. Warning signs can include spreading redness, heat, swelling, worsening pain, pus-like fluid, fever, chills, or an unusual odour.
An infection can require medication, incision care, removal of fluid, or an additional procedure. An infected breast implant or other medical device may need to be removed. Infection risk and treatment difficulty may increase with smoking, poorly controlled diabetes, inadequate nutrition, or reduced circulation.
Fluid Buildup or Seroma
A seroma is a pocket of clear fluid that collects under the skin. 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.
A minor fluid collection can sometimes disappear as the body reabsorbs it. Repeated drainage may be necessary when a significant seroma develops. If fluid is not treated, it may strain the incision, delay healing, or lead to 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. 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.
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. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable.
Delayed or Difficult Wound Healing
Slow healing or separation of the incision can occur after cosmetic surgery. Factors such as reduced blood flow, infection, wound tension, nicotine use, medications, and illness may prevent normal healing.
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. Healing in this way often takes more time and can result in a more noticeable scar.
Skin or Tissue Necrosis
When skin, fat, or other tissue loses its blood supply and starts to die, the condition is called necrosis. 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.
Management of necrosis varies according to the size and depth of the affected area. It may involve wound care, removal of damaged tissue, skin grafting, reconstructive surgery, or a delayed revision.
Risks Related to Anesthesia
Depending on the operation, cosmetic surgery can involve local anesthetic, sedating medication, general anesthesia, or multiple methods together. 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:
- Postoperative nausea or vomiting
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- Headache or sore throat
- Unexpected reactions to anesthetic or other medications
- Changes in blood pressure or heart rhythm
- Respiratory difficulty
- Aspiration, which occurs when material from the stomach reaches the lungs
- Damage to teeth, lips, or the airway
- Serious heart, lung, or neurological complications
A preoperative health history should include every medication, vitamin, supplement, cannabis product, alcohol or nicotine habit, allergy, previous anesthetic reaction, and relevant diagnosis. Withholding medical or lifestyle information may increase the risks of anesthesia and surgery.
Cosmetic Surgery Scars and Skin Changes
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. They may soften and fade over 12 months or longer. Genetic factors, skin characteristics, pressure on the incision, infection, sunlight, wound care, surgical location, and procedure type all influence the finished scar.
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. Patients should inform their surgeon if they or close family members have developed raised or unusual scars.
Raised or visible scars may be treated with silicone, compression, copyright injections, laser procedures, or surgical 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. Some of these changes resolve over time, while others can last permanently. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
Cosmetic Outcome Risks and Patient Dissatisfaction
A technically successful operation does not always produce the appearance a patient expected. Individual anatomy, skin flexibility, age, past procedures, scarring, and natural asymmetry all affect healing.
Possible aesthetic concerns include:
- Unevenness that remains after healing
- Uneven contours or visible irregularities
- Too little or too much correction
- An artificial-looking or over-tightened outcome
- Alterations in shape while swelling resolves
- Movement or poor positioning of an implant
- Noticeable scars or scars in an unfavourable location
- A return of looseness or sagging with age and time
- Disappointment with an outcome that falls within an acceptable surgical range
Visual examples and digital imaging can guide consultation discussions, although no patient can be guaranteed the same outcome. Each patient has different anatomy and heals in a different way.
Revision Cosmetic Surgery
Revision surgery may be considered when a complication occurs or when the result can be improved. A second procedure introduces another set of surgical 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. Additional costs for the surgeon, operating room, anesthetic, implants, medicine, transportation, accommodation, and missed employment may fall outside the initial price.
Risks Associated With Specific Cosmetic Procedures
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Facelift and Neck Lift Risks
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. Nicotine use can greatly increase the risk of skin-healing problems.
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. It can take at least a year for swelling to resolve enough for the final nasal shape to be assessed. A revision nose operation is often more challenging because the first surgery changes the cartilage and creates internal scarring.
Eyelid Surgery Risks
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. Severe eye pain or a sudden change in vision requires urgent medical assessment.
Breast Surgery Risks
Procedures such as breast augmentation, mastopexy, and breast reduction can change nipple feeling, breast balance, scarring, and future breastfeeding ability. Hematoma, infection, fat necrosis, poor healing, and altered nipple or areola position are also possible.
Breast implants bring added long-term considerations. Capsular contracture, rupture, deflation, rippling, displacement, rotation, pain, ongoing imaging, and future surgery may occur with breast implants. 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 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. Patients may need several weeks of movement restrictions.
Risks of Fat Transfer
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. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area.
Who Has a Higher Risk of Complications?
Certain medical conditions and lifestyle habits increase surgical risk. Preoperative preparation may include laboratory testing, medication changes, weight management, stopping nicotine, or obtaining medical clearance.
Risk factors may include:
- Cigarette smoking, vaping, or any form of nicotine use
- Diabetes that is not well controlled
- Heart, lung, kidney, liver, or blood vessel disease
- A bleeding disorder or history of blood clots
- Obesity or major weight changes
- A diagnosed or suspected sleep-related breathing disorder
- Conditions affecting the immune system
- Inadequate nutrition or serious anemia
- Scar tissue or circulation changes from prior operations or radiation
- Drugs, vitamins, or supplements that interfere with clotting or tissue repair
- Unrealistic expectations or untreated mental health concerns that affect decision-making
A higher-risk medical history does not necessarily make an operation unsuitable. It means the surgeon must decide whether the procedure can be performed safely and whether changes are needed before proceeding.
Psychological and Emotional Risks
The effects of cosmetic surgery may be psychological and emotional, not only physical. Swelling, bruising, fatigue, and temporary lifestyle restrictions may leave some patients feeling worried, frustrated, or low. The term postoperative blues is sometimes used to describe this temporary decline in mood.
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 careful cosmetic surgery consultation should examine why the patient wants the procedure. Possible warning signs include outside pressure, ongoing dissatisfaction despite multiple operations, severe concern about a minor feature, and unrealistic beliefs about total life transformation.
Intense and persistent concern about perceived physical defects may be a sign of body dysmorphic disorder, a recognized mental health condition. 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.
Ways to Lower Cosmetic Surgery Risks
Cosmetic surgery always carries some risk, yet careful planning can reduce the likelihood of complications.
- Select a qualified doctor who has appropriate education and substantial experience performing the procedure.
- Verify the physician's registration and standing through the medical regulatory authority in your province or territory.
- Ask where the procedure will be performed and what safety, emergency, and infection-control systems are available.
- Give the surgical team accurate information about diagnoses, operations, prescriptions, supplements, substances, and allergies.
- Complete required testing and obey instructions about fasting, medicines, supplements, smoking, vaping, and other nicotine products.
- Arrange a responsible adult to drive you home and assist during early recovery when required.
- Understand the recovery timeline before booking work, travel, exercise, or major events.
- Attend all follow-up appointments and report unusual symptoms promptly.
- Avoid judging your recovery against filtered photographs or the healing experience of someone else.
- Allow swelling and scar tissue to settle fully before considering corrective surgery.
Choosing a Cosmetic Surgeon in Canada
In Canada, physicians are licensed and regulated by provincial and territorial authorities. Patients may verify a physician's licence and registered specialty through the online register maintained by their provincial or territorial regulator.
Patients may also ask whether a surgeon is certified in plastic surgery by 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.
Useful questions for facial rejuvenation plastic surgery a cosmetic surgery consultation include:
- What are your surgical qualifications and specialty credentials?
- How many times have you carried out this operation?
- Am I a suitable candidate based on my health and anatomy?
- Which problems do your patients experience most often after this operation?
- Which uncommon but severe complications need to be considered?
- Who is responsible for anesthesia care during the operation?
- How can I obtain care if a problem develops at night or on a weekend?
- What emergency plan is in place if I need urgent medical treatment?
- What follow-up visits are included?
- Which additional expenses would I be responsible for if a complication or revision occurs?
What Informed Consent Should Include
Signing paperwork alone does not create true informed consent. It is an ongoing discussion that should give the patient enough information to make a voluntary decision.
Patients should be informed about how the operation works, its likely benefits, material risks, alternatives, healing process, limits, and the possible consequences of no surgery. The surgeon should also explain risks that may have particular importance because of the patient's occupation, health, daily activities, or individual goals.
A patient should never feel rushed to sign. 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
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
- Unexpected pain, swelling, redness, or heat affecting one leg
- Significant bleeding or swelling that expands quickly
- Intense pain that does not improve after taking the recommended medicine
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- 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
- Repeated vomiting or an inability to keep fluids down
- Any problem your surgeon specifically described as requiring emergency care
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.
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.
Before an operation, patients should ask who pays for treatment if a complication develops. Health coverage for complications varies based on medical necessity, treatment setting, and the applicable provincial or territorial insurance plan. Patients should budget for possible travel, lodging, caregiving, time away from employment, child care, and future revision surgery.
Patients considering medical tourism should think about who will provide follow-up care after returning to Canada. Lower upfront fees may become more expensive if postoperative infection, wound breakdown, clotting, implant complications, or revision treatment is required.
Weighing Cosmetic Surgery Benefits Against Risks
Patients should consider surgery only when their goals are achievable, their health is suitable, and they understand the risks and recovery. A suitable patient recognizes that improvement is possible, but perfection is not.
Patients should carefully weigh likely improvements against health risks, emotional effects, recovery demands, and financial costs. Consider whether you can follow the recovery plan, accept visible scars, manage time away from work, and cope with the possibility of an imperfect result.
A qualified surgeon may advise against a procedure when the risk is too high, the expected benefit is limited, or the patient's goals cannot be achieved safely. A decision not to operate is sometimes the safest and most responsible form of patient care.
Deciding Whether Cosmetic Surgery Is Right for You
Learning about cosmetic surgery risks does not mean expecting that something will go wrong. Instead, risk awareness allows patients to decide using reliable facts rather than marketing, online trends, or cost as the only factor.
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.
