Through cosmetic surgery, patients may change the shape, proportions, or appearance of their face or body. 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. Before deciding whether a procedure is suitable, it is essential to understand the risks of cosmetic surgery.
A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. Complications may result from anesthesia, bleeding, infection, delayed healing, unexpected reactions, or an individual response to surgery. Some complications are temporary and easy to treat. 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 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.
What Are the Risks of Cosmetic Surgery?
The risks of cosmetic surgery include unwanted outcomes that affect health, physical function, or appearance. 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. Swelling, bruising, soreness, numbness, tightness, fatigue, and mild drainage may be normal during early healing. A complication is different. A complication extends beyond normal recovery and may need medical care.
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
- A collection of fluid called 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 injury, numbness, or altered sensation
- Loss of skin, fat, or other tissue because of reduced circulation
- Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials
- Unevenness, contour irregularities, or an unsatisfactory appearance
- 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. 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
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
Pain levels vary by procedure and patient. The surgical site can feel tender, tight, sore, or mildly burning during recovery. As recovery progresses, pain should generally become less intense and easier to control. Patients should quickly report severe or spreading pain, especially when it is accompanied by fever, redness, shortness of breath, or unusual swelling.
Swelling and Bruising
Swelling develops when inflammation allows fluid to collect in and around the treated area. The early result can remain difficult to assess until swelling subsides over the following weeks or months. 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. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Changes in Feeling After Surgery
During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Some procedures commonly cause short-term numbness, tingling, increased sensitivity, or a decrease in feeling. Feeling frequently returns as the nerves heal, although full recovery is not certain. Permanent sensory changes are possible.
Activity Limitations During Recovery
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. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Medical and Surgical Risks
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. Possible signs of a hematoma include worsening pain, hard swelling, colour changes, or sudden asymmetry.
A small hematoma may only need monitoring, but a larger one may require drainage. A return to the operating room may be necessary in more serious cases.
Infection After Cosmetic Surgery
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.
Antibiotics, specialized wound care, drainage, or further surgery may be needed to treat an infection. Removal can be required when infection develops around a breast implant or surgical device. Patients who smoke or have uncontrolled diabetes, nutritional problems, or poor blood flow may face a higher infection risk and slower recovery.
Seroma
Clear fluid that gathers beneath the skin is known as a seroma. Procedures such as abdominoplasty, body lift surgery, breast surgery, and large-area liposuction may have a greater seroma risk because they create space beneath the tissue.
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
Deep vein thrombosis, known as DVT, develops when a clot forms in one of the body's deep veins, usually in a leg. If part of the clot travels to the lungs, it can cause a pulmonary embolism. This is a medical emergency.
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. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable.
Problems With Incision Healing
Slow healing or separation of the incision can occur after cosmetic surgery. Healing may be impaired by poor circulation, infection, pressure on the incision, nicotine, some medicines, or underlying health conditions.
Wound problems may require dressings, antibiotics, removal of damaged tissue, or additional surgery. Healing by secondary intention means allowing an open area to close gradually from the inside outward. This process can take longer and may leave a more visible scar.
Skin or Tissue Necrosis
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.
Treatment depends on the amount of tissue affected. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery.
Anesthesia Risks in Cosmetic Surgery
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.
Potential complications connected with anesthesia include:
- Postoperative nausea or vomiting
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- A headache or irritation of the throat
- An allergic response or adverse drug reaction
- 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
- Serious heart, lung, or neurological complications
Patients must provide cosmetic surgery nearby 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.
Cosmetic Surgery Scars and Skin Changes
Whenever an incision is made through the skin, a scar will form. A surgeon may try to conceal incisions in folds, hair-bearing areas, or covered locations, but complete scar elimination is not possible.
During the first stages of healing, scars may look red, thick, firm, elevated, or darker than nearby skin. Over 12 months or longer, scar tissue can gradually fade and soften. How a scar eventually looks is affected by heredity, skin type, wound tension, infection, ultraviolet exposure, aftercare, incision placement, and the operation performed.
Hypertrophic Scars and Keloids
Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. 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.
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.
Changes in Skin Colour and Texture
The treated skin may develop colour changes, redness, noticeable blood vessels, dimpling, firmness, or textural differences. These effects may be temporary or permanent. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
The Risk of an Unwanted Cosmetic Result
A procedure can be medically and technically successful while still producing a result the patient did not anticipate. The body's response is shaped by age, anatomy, skin quality, earlier surgery, scar development, and normal side-to-side differences.
Possible aesthetic concerns include:
- Persistent asymmetry
- Uneven contours or visible irregularities
- A result that is under-treated or over-treated
- A result that appears unnatural or excessively tight
- Alterations in shape while swelling resolves
- Movement or poor positioning of an implant
- Scarring that is prominent or difficult to conceal
- Gradual recurrence of skin or tissue laxity
- Patient dissatisfaction even when the result is medically acceptable
Visual examples and digital imaging can guide consultation discussions, although no patient can be guaranteed the same outcome. Anatomy and healing responses vary from one person to another.
Corrective and 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. Scar tissue can make the procedure more complex, and the tissues may have less blood supply or flexibility than they did before the first surgery.
Before proceeding, patients should understand exactly what is included in the surgeon's or clinic's revision policy. Surgeon fees, facility costs, anesthesia, implants, medications, travel, and time away from work may not all be included in the original price.
Risks Associated With Specific Cosmetic Procedures
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Risks of Facelift and Neck Lift Surgery
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. Nicotine use can greatly increase the risk of skin-healing problems.
Risks of Nose Surgery
After nose surgery, patients may experience persistent swelling, nosebleeds, infection, asymmetry, smell changes, irregular contours, septal perforation, collapse of nasal support, or obstructed breathing. A rhinoplasty result may not fully settle for 12 months or more. Revision rhinoplasty can be more difficult because of scar tissue and changes to the cartilage.
Possible Complications of Eyelid Surgery
Blepharoplasty risks include dry or irritated eyes, temporary blurred vision, difficulty closing the eyelids, eyelid malposition, asymmetry, scarring, bleeding behind the eye, and changes in vision. Severe eye pain or a sudden change in vision requires urgent medical assessment.
Risks of Cosmetic Breast Surgery
Procedures such as breast augmentation, mastopexy, and breast reduction can change nipple feeling, breast balance, scarring, and future breastfeeding ability. Additional complications can include bleeding beneath the tissue, infection, fat tissue death, slow wound healing, and changes to the nipple or areola location.
Implant-based breast surgery involves long-term risks beyond the normal surgical recovery period. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. Breast implants are not designed to last for an entire lifetime. Health Canada also provides safety information about uncommon conditions linked with certain breast implants, including breast implant-associated anaplastic large cell lymphoma.
Risks of Liposuction
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. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated.
Risks of Abdominoplasty and Body Lift Surgery
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. Seroma, blood clots, infection, necrosis, delayed wound healing, numbness, noticeable scars, and altered belly button position may occur. Recovery may involve several weeks of limited movement and physical activity.
Fat Grafting Risks
During fat grafting, fat is taken from one body area and placed into a different location. The body naturally absorbs some transferred fat, potentially reducing volume or creating asymmetry. Other risks include fat necrosis, cysts, calcification, infection, oil cysts, and accidental injection into a blood vessel. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area.
Who May Face Greater Cosmetic Surgery Risks?
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.
Factors associated with higher surgical risk 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 clotting or bleeding condition, or previous blood clots
- Obesity or major weight changes
- Sleep apnea
- Conditions affecting the immune system
- Poor nutrition or significant anemia
- Earlier surgery or radiation therapy involving the same area
- Prescription products, non-prescription medicines, or supplements that alter bleeding and healing
- Unrealistic expectations or untreated mental health concerns that affect 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.
Psychological Effects of Cosmetic Surgery
Cosmetic surgery can affect emotional health as well as physical health. Swelling, bruising, fatigue, and temporary lifestyle restrictions may leave some patients feeling worried, frustrated, or low. 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. An operation may fail to resolve the deeper psychological distress. In suitable cases, the surgeon may delay treatment and advise the patient to seek mental health assessment or counselling first.
How to Reduce the Risks of Cosmetic Surgery
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.
- Find out which facility will be used and whether it has suitable emergency plans, safety standards, and infection prevention measures.
- Give the surgical team accurate information about diagnoses, operations, prescriptions, supplements, substances, and allergies.
- 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.
- Understand the recovery timeline before booking work, travel, exercise, or major events.
- Follow-up care should not be skipped, and abnormal changes should be reported without delay.
- 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.
Finding a Qualified Canadian Cosmetic Surgeon
Medical regulation in Canada is handled at the provincial and territorial level. 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. While certification matters, patients should also assess procedure-specific experience, communication, the quality of the facility, aftercare, and the surgeon's approach to complications.
Useful questions for a cosmetic surgery consultation include:
- What professional education and certifications have you completed?
- How frequently is this specific procedure performed in your practice?
- Based on my health, goals, and anatomy, is this procedure suitable for me?
- 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?
- How can I obtain care if a problem develops at night or on a weekend?
- Where would I receive emergency care if needed?
- What follow-up visits are included?
- Which additional expenses would I be responsible for if a complication or revision occurs?
Informed Consent for Cosmetic Surgery
Informed consent is more than signing a form. 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. Taking notes, involving a support person, and reviewing written material outside the clinic can support an informed decision.
Warning Signs After Cosmetic Surgery
Patients should receive clear directions about warning signs, emergency care, and after-hours communication. 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
- Heavy bleeding or rapidly increasing swelling
- Pain that remains severe despite the prescribed treatment plan
- A significant fever, shaking chills, expanding redness, or thick discharge
- Confusion, extreme weakness, or difficulty staying awake
- A pale, dark, blistered, or unusually cold area of skin
- 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. 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.
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. Out-of-pocket expenses may include the surgeon, anesthesia provider, operating room, medical devices, recovery clothing, prescriptions, laboratory work, and follow-up items.
The financial responsibility for postoperative problems should be clarified in advance. 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.
Medical tourists need to determine which Canadian provider, if any, will manage recovery and complications after their return. A lower initial price may not include management of infection, wound problems, blood clots, implant complications, or revision surgery.
Balancing the Benefits 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. Realistic patients seek meaningful improvement while accepting that no procedure can deliver a flawless result.
Before deciding, compare what the operation may achieve with its physical, psychological, practical, and economic consequences. The decision should account for recovery restrictions, permanent scarring, employment absence, and the possibility that the final result may fall short of expectations.
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.
Learn about the procedure, review your personal risk factors, confirm the surgeon's qualifications, ask detailed questions, and plan for a full recovery. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
