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. However, every operation involves some degree of uncertainty. 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. The procedure being performed, technique used, body area treated, duration of surgery, anesthesia method, and patient health all influence risk.
It is normal for patients to experience some minor effects after many operations. During early recovery, swelling, bruising, tenderness, numbness, tightness, tiredness, and light drainage may be normal. Expected healing effects and surgical complications are different. It is a problem that goes beyond the expected recovery process and may require medical treatment.
Possible complications of plastic surgery include:
- Bleeding or the development of a blood collection known as a hematoma
- Infection at the incision or within deeper tissue
- 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
- Visible scarring that may be thick, widened, raised, or irregular
- Damage to nerves, loss of feeling, or changes in sensation
- Skin, fat, or tissue loss caused by poor blood supply
- Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials
- Asymmetry, contour problems, or an unwanted appearance
- Problems with normal function, including breathing, motion, or sensation
- The need for additional treatment or revision surgery
Serious complications are uncommon, but they are still important to discuss. Rare risks may include severe infection, major blood loss, organ injury, heart problems, stroke, pulmonary embolism, permanent disability, or death.
Common Short-Term Effects After 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.
Postoperative 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. Pain should usually become easier to manage as healing continues. 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. 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. Temporary changes such as tingling, numbness, tenderness, or reduced sensation may occur after surgery. 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
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. Failing to follow activity restrictions may raise the risk of bleeding, swelling, wound breakdown, and other problems.
Medical and Surgical Risks
Bleeding or Blood Collection
Minor bleeding near a surgical incision can occur during early recovery. Heavier bleeding may create a hematoma, a pocket of blood beneath the skin or within the treated area. Increasing tenderness, firmness, swelling, discolouration, or an abrupt difference between two sides may indicate a hematoma.
Some hematomas can be observed, while others must be drained. A return to the operating room may be necessary in more serious cases.
Infection
The incision, nearby skin, deeper surgical tissues, or an implant pocket can become infected. Warning signs can include spreading redness, heat, swelling, worsening pain, pus-like fluid, fever, chills, or an unusual odour.
Antibiotics, specialized wound care, drainage, or further surgery may be needed to treat an infection. 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.
Postoperative 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.
Small seromas may resolve as the body absorbs the fluid. Larger ones may need to be drained, sometimes more than once. Untreated fluid can place pressure on the incision, affect healing, or become infected.
Blood Clot Complications
A blood clot that forms in a deep vein, commonly within the leg, is called deep vein thrombosis, or DVT. If part of the clot travels to the lungs, it can cause a pulmonary embolism. 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. Reduced blood supply, infection, tension on the wound, nicotine exposure, certain medications, and medical conditions can interfere with healing.
Incision problems may need wound care, antibiotics, surgical cleaning, or further corrective surgery. Healing by secondary intention means allowing an open area to close gradually from the inside outward. The recovery period may be extended, and the final scar may be more prominent.
Skin or Tissue Necrosis
Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to die. Tissue loss may occur after procedures involving extensive lifting, tightening, or repositioning. 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. Possible treatment includes wound management, removal of dead tissue, a skin graft, reconstructive surgery, or revision at a later date.
Risks Related to Anesthesia
Local anesthesia, sedation, general anesthesia, or a combination may be used during cosmetic surgery. The safest choice depends on the operation, the patient's medical history, the expected length of surgery, and the surgical setting.
Anesthesia may be associated with the following risks:
- Feeling sick or vomiting after anesthesia
- Light-headedness, confusion, or extended sleepiness
- Throat discomfort or headache
- Allergic or medication reactions
- Changes in blood pressure or heart rhythm
- Problems with breathing
- Aspiration, which occurs when material from the stomach reaches the lungs
- Damage to teeth, lips, or the airway
- Major complications involving the heart, lungs, or nervous system
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.
Scarring and Changes to the Skin
Whenever an incision is made through the skin, a scar will form. Incisions are often positioned in natural creases, along hairlines, or beneath clothing, although no scar can be removed entirely.
Scars often appear red, raised, firm, or darker during early healing. Scars may require a year or more to flatten, soften, and become less noticeable. 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 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. Scar treatment may improve texture and appearance, but it cannot ensure that a hypertrophic scar or keloid will never come back.
Skin Colour and Texture Changes
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. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
Aesthetic Risks and Unsatisfactory Results
A technically successful operation does not always produce the appearance a patient expected. Healing is affected by anatomy, skin elasticity, age, previous surgery, scar formation, and natural differences between the two sides of the body.
Possible aesthetic concerns include:
- Ongoing asymmetry
- Irregular or uneven body contours
- Under-correction or over-correction
- An artificial-looking or over-tightened outcome
- Alterations in shape while swelling resolves
- Implant position problems
- Scarring that is prominent or difficult to conceal
- 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. However, another operation brings new 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.
It is important to ask how the practice handles revisions and which expenses are covered. Additional costs for the surgeon, operating room, anesthetic, implants, medicine, transportation, accommodation, and missed employment may fall outside the initial price.
Risks Associated With Specific Cosmetic Procedures
Although many operations share common complications, every cosmetic procedure has its own specific risks.
Risks of Facelift and Neck Lift Surgery
Facelift and neck lift complications may include hematoma, facial nerve injury, hairline changes, hair loss near incisions, skin loss, contour irregularities, earlobe distortion, numbness, facial weakness, and visible scarring. Smoking, vaping, and other nicotine exposure can significantly raise the chance of skin loss and delayed healing.
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. The final shape may take a year or longer to become clear. Scar formation and altered cartilage can make secondary rhinoplasty more complex.
Blepharoplasty 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. Immediate medical evaluation is needed for intense eye pain or a sudden visual disturbance.
Breast Surgery Risks
Breast augmentation, breast lift, and breast reduction may affect nipple sensation, breast symmetry, scar appearance, and the ability to breastfeed. Hematoma, infection, fat necrosis, poor healing, and altered nipple or areola position are also possible.
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. Implants are not lifetime devices. Patients in Canada can review Health Canada information about uncommon implant-related conditions, such as 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
Tummy tuck and body lift procedures require long incisions and repositioning of broad tissue areas. Risks include seroma, blood clots, infection, skin loss, wound separation, numbness, prominent scarring, and changes to the position or shape of the belly button. Patients may need several weeks of movement restrictions.
Risks of Fat Transfer
Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. Because a portion of the injected fat may not survive, the final fullness and balance can change. Additional complications include dead fat tissue, cysts, calcification, infection, oil cysts, and fat entering a blood vessel. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area.
Who Has a Higher Risk of Complications?
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.
Risk factors may include:
- Smoking, vaping, or using nicotine products
- Diabetes with unstable or elevated blood sugar
- Heart, lung, kidney, liver, or blood vessel disease
- A clotting or bleeding condition, or previous blood clots
- A high body mass index or significant changes in weight
- A diagnosed or suspected sleep-related breathing disorder
- Immune system disorders
- Poor nutrition or significant anemia
- Previous radiation or surgery in the treatment area
- Medications or supplements that affect bleeding or healing
- Expectations that cannot be achieved or unaddressed psychological concerns affecting consent
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 Effects of Cosmetic Surgery
Cosmetic surgery can affect emotional health as well as physical health. During recovery, patients can become anxious or discouraged because they look swollen, feel tired, and cannot resume normal activities. 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.
A responsible assessment should explore the patient's reasons for seeking surgery. Possible warning signs include outside pressure, ongoing dissatisfaction despite multiple operations, severe concern about a minor feature, and unrealistic beliefs about total life transformation.
Body dysmorphic disorder is a mental health condition involving intense distress about perceived appearance flaws. 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.
- Verify the physician's registration and standing through the medical regulatory authority in your province or territory.
- Discuss the surgical location, its safety procedures, infection-control practices, and ability to handle emergencies.
- Give the surgical team accurate information about diagnoses, operations, prescriptions, supplements, substances, and allergies.
- Carefully follow all directions related to eating, drinking, preoperative tests, medication adjustments, and nicotine cessation.
- 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.
- Do not compare your healing speed with edited images or another patient's recovery.
- Wait until healing is mature before deciding whether revision surgery is needed.
How to Select a Cosmetic Surgeon in Canada
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.
Canadian patients can ask if their surgeon has been 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.
Questions to ask during a cosmetic surgery consultation include:
- 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?
- 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?
- Which follow-up visits and services are included in the fee?
- Which additional expenses would I be responsible for if a complication or revision occurs?
Informed Consent for Cosmetic Surgery
Informed consent is more than signing a form. 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. Any complication that could significantly affect the patient's medical condition, employment, lifestyle, or priorities should receive special attention.
A patient should never feel rushed to sign. When medical language or a possible complication is confusing, the patient should request a clearer explanation. Taking notes, involving a support person, and reviewing written material outside the clinic can support an informed decision.
When to Seek Help After Cosmetic Surgery
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.
Potential emergency signs after cosmetic surgery include:
- Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness
- Sudden swelling, pain, redness, or warmth in one leg
- Uncontrolled bleeding or a sudden increase in swelling
- Pain that remains severe despite the prescribed treatment plan
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Disorientation, marked weakness, or excessive drowsiness
- Possible tissue damage shown by abnormal colour, blistering, or low skin temperature
- An emergency eye symptom such as severe pain, sudden visual change, or vision loss
- Repeated vomiting or an inability to keep fluids down
- Any problem your surgeon specifically described as requiring emergency care
Emergency medical services should be contacted immediately for potentially life-threatening complications. 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.
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. Extra costs may arise from transportation, hotels, private nursing, lost income, family care, and corrective procedures.
Patients considering medical tourism should think about who will provide follow-up care after returning to Canada. An inexpensive overseas package may exclude the cost of treating elective cosmetic plastic surgery infection, poor healing, DVT, implant problems, and corrective operations.
Weighing Cosmetic Surgery Benefits Against Risks
A sound decision about cosmetic surgery requires realistic expectations, appropriate health, informed consent, and knowledge of the healing process. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection.
Take time to compare the expected benefit with the medical, emotional, practical, and financial risks. 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.
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.
Before surgery, research the operation, assess your health risks, verify medical credentials, ask thorough questions, and prepare for the complete healing period. When the benefits, limits, alternatives, and possible complications are understood, patients are better prepared to decide whether cosmetic surgery fits their needs.
