The shape, proportion, or overall appearance of the face and body can be enhanced through cosmetic surgery. For some people, it can also increase comfort with a physical feature that has caused distress for years. 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.
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 complications are temporary and easy to treat. Others may require medication, hospital care, revision surgery, or long-term follow-up.
Patients in Canada should receive clear information about the expected benefits, material risks, alternatives, recovery requirements, and possible consequences of not having treatment. A careful consultation gives you time to consider this information without pressure. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits.
What Are the Risks of Cosmetic Surgery?
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.
Minor side effects are expected after many procedures. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. Expected healing effects and surgical complications are different. It is a problem that goes beyond the expected recovery process and may require medical treatment.
Plastic surgery complications may include the following:
- Bleeding or a collection of blood called a hematoma
- An infection in the incision or deeper surgical tissues
- A collection of fluid called a seroma
- Clots that form in a leg vein or travel to the lungs
- Slow wound healing or separation of the incision
- Noticeable, raised, widened, or uneven scars
- Damage to nerves, loss of feeling, or changes in sensation
- Tissue damage or loss resulting from inadequate blood flow
- Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials
- Aesthetic concerns such as asymmetry, poor contours, or an unwanted result
- Problems with normal function, including breathing, motion, or sensation
- A need for further care or corrective 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.
Expected Short-Term Effects of 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.
Soreness After Cosmetic Surgery
The amount of pain experienced depends on both the procedure and the individual. Tightness, aching, burning, or tenderness may occur near the surgical 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.
Swelling and Bruising
Swelling is caused by inflammation and fluid moving into the treated tissues. The early result can remain difficult to assess until swelling subsides over the following weeks or months. Bruising occurs when small blood vessels leak beneath the skin. Patients undergoing face surgery, breast surgery, liposuction, or body contouring may experience noticeable bruising and swelling.
The outcome of surgery should minimally invasive plastic surgery not be assessed before healing has progressed. Remaining swelling may temporarily affect shape, balance, and the texture of the skin.
Changes in Feeling After Surgery
Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. Some procedures commonly cause short-term numbness, tingling, increased sensitivity, or a decrease in feeling. Feeling frequently returns as the nerves heal, although full recovery is not certain. There is a possibility that altered feeling will not fully resolve.
Temporary Limits on Activity
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. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Medical and Surgical Risks
Postoperative Bleeding and Hematoma
A small amount of bleeding may occur around an incision. More significant bleeding can form a hematoma, which is a collection of blood beneath the skin or inside the surgical area. Increasing tenderness, firmness, swelling, discolouration, or an abrupt difference between two sides may indicate a hematoma.
Depending on its size and symptoms, a hematoma may be watched or medically drained. Some hematomas require another operation to control the bleeding and remove collected blood.
Surgical Infection
An infection can develop in the skin, incision, tissue, or around an implant. Possible signs include increasing redness, warmth, swelling, pus-like drainage, worsening pain, fever, chills, or an unpleasant smell.
Treatment may involve antibiotics, wound care, drainage, or another operation. Removal can be required when infection develops around a breast implant or surgical device. 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. 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. A larger seroma may require drainage on one or several occasions. Untreated fluid can place pressure on the incision, affect healing, or become infected.
Blood Clots and Pulmonary Embolism
Deep vein thrombosis, known as DVT, develops when a clot forms in one of the body's deep veins, usually in a leg. When part of a deep vein clot moves into the lungs, it may block blood flow and cause a pulmonary embolism. This is a medical emergency.
Risk may increase with long operations, limited movement, previous blood clots, certain medications, nicotine use, obesity, some medical conditions, and combining multiple procedures. Depending on the patient, preventive steps may involve getting up early, using compression equipment or garments, staying hydrated, or taking prescribed blood thinners.
Problems With Incision Healing
A surgical wound may take longer than expected to close or may start to open. Factors such as reduced blood flow, infection, wound tension, nicotine use, medications, and illness may prevent normal healing.
Incision problems may need wound care, antibiotics, surgical cleaning, or further corrective surgery. Secondary intention healing allows an open wound to fill and close naturally from the bottom upward. This process can take longer and may leave a more visible scar.
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.
Treatment depends on the amount of tissue affected. It may involve wound care, removal of damaged tissue, skin grafting, reconstructive surgery, or a delayed revision.
Anesthesia Risks in Cosmetic Surgery
Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. Choosing an anesthesia method requires consideration of the operation, medical background, expected surgical time, and facility.
Possible anesthesia-related problems include:
- Postoperative nausea or vomiting
- Dizziness, confusion, or prolonged drowsiness
- Throat discomfort or headache
- An allergic response or adverse drug reaction
- Fluctuations in blood pressure or disturbances in heartbeat
- Respiratory difficulty
- Aspiration of stomach contents into the lungs
- Dental, lip, or airway damage
- Major complications involving the heart, lungs, or nervous system
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. The safety of the operation can be reduced when important health information is omitted.
Changes in Scarring, Colour, and Skin Texture
A surgical procedure that breaks the skin will always leave some degree of scarring. A surgeon may try to conceal incisions in folds, hair-bearing areas, or covered locations, but complete scar elimination is not possible.
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. 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
A hypertrophic scar becomes thick or raised but stays within the original wound. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. 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
Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin texture. Alterations in colour or texture may improve, but they can also remain long term. 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. Healing is affected by anatomy, skin elasticity, age, previous surgery, scar formation, and natural differences between the two sides of the body.
Appearance-related problems may include:
- Persistent asymmetry
- Irregular or uneven body contours
- 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
- Visible or poorly placed scars
- Recurrence of sagging or tissue laxity over time
- Dissatisfaction despite an acceptable medical result
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.
Revision Cosmetic Surgery
A corrective operation may be discussed if a complication develops or if the original result could be refined. A second procedure introduces another set of surgical 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.
Facelift and Neck Lift Risks
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. Nicotine use can greatly increase the risk of skin-healing problems.
Rhinoplasty Risks
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. Revision rhinoplasty can be more difficult because of scar tissue and changes to the cartilage.
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. Severe eye pain or a sudden change in vision requires urgent medical assessment.
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.
Implant-based breast surgery involves long-term risks beyond the normal surgical recovery period. 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. Patients in Canada can review Health Canada information about uncommon implant-related conditions, such as breast implant-associated anaplastic large cell lymphoma.
Liposuction Risks
Liposuction complications may include contour irregularities, dents, rippling, loose skin, fluid imbalance, numbness, seroma, infection, internal injury, fat embolism, and lidocaine toxicity when local anesthetic is used. 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
Tummy tuck and body lift procedures require long incisions and repositioning of broad tissue areas. 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
Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. 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 location where fat is injected, such as the face, breasts, or buttocks, affects the type and seriousness of potential complications.
Who May Face Greater Cosmetic Surgery Risks?
Certain medical conditions and lifestyle habits increase surgical risk. 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:
- Cigarette smoking, vaping, or any form of nicotine use
- Diabetes with unstable or elevated blood sugar
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- Past DVT, pulmonary embolism, or a diagnosed bleeding disorder
- Obesity, unstable weight, or recent major weight loss or gain
- A diagnosed or suspected sleep-related breathing disorder
- Immune system disorders
- Inadequate nutrition or serious anemia
- Earlier surgery or radiation therapy involving the same area
- Prescription products, non-prescription medicines, or supplements that alter bleeding and healing
- 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.
Psychological and Emotional Risks
An operation performed for appearance can influence a patient's mental and emotional state in addition to the body. 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.
More serious dissatisfaction can occur when expectations do not match what surgery can realistically achieve. 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. Warning signs may include pressure from another person, repeated procedures without satisfaction, extreme focus on a minor feature, or the belief that one operation will completely transform a person's 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
Cosmetic surgery always carries some risk, yet careful planning can reduce the likelihood of complications.
- 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.
- 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.
- Complete required testing and obey instructions about fasting, medicines, supplements, smoking, vaping, and other nicotine products.
- When needed, organize transportation and early postoperative support from a responsible adult.
- Review the expected healing schedule before arranging employment, trips, strenuous activity, or important occasions.
- Go to every scheduled postoperative visit and quickly contact the surgical team about unexpected symptoms.
- 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
Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. 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.
Useful questions for a cosmetic surgery consultation include:
- What professional education and certifications have you completed?
- How often do you perform this procedure?
- Does my medical history and physical anatomy make me an appropriate candidate?
- What are the most common complications in your practice?
- Which uncommon but severe complications need to be considered?
- Who will provide anesthesia?
- 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?
- 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
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.
The consent process should cover the nature of the procedure, expected benefits, important risks, reasonable alternatives, recovery, limitations, and what could happen without 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. Ask for clarification when a term or complication is unclear. Patients may benefit from writing down information, attending with someone they trust, and reading the documents again at home.
When to Seek Help After Cosmetic Surgery
The surgeon's office should explain which symptoms require attention and copyright the appropriate provider. Unexpected or worsening symptoms that fall outside the recovery instructions should be reported without delay.
Urgent warning signs may include:
- Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness
- One-sided leg swelling, tenderness, warmth, or discolouration
- 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
- Sudden vision loss, severe eye pain, or major visual changes
- Ongoing vomiting or difficulty drinking without becoming sick
- A symptom listed as urgent in the postoperative instructions
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.
Financial Risks and Health Coverage in Canada
Procedures performed only to change appearance are generally not covered by provincial or territorial health insurance. 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. Extra costs may arise from transportation, hotels, private nursing, lost income, family care, and corrective procedures.
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.
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. 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. A decision not to operate is sometimes the safest and most responsible form of patient care.
How to Make an Informed Cosmetic Surgery Decision
Being aware of possible complications is not the same as believing they are certain to happen. Instead, risk awareness allows patients to decide using reliable facts rather than marketing, online trends, or cost as the only factor.
Learn about the procedure, review your personal risk factors, confirm the surgeon's qualifications, ask detailed questions, and plan for a full recovery. When the benefits, limits, alternatives, and possible complications are understood, patients are better prepared to decide whether cosmetic surgery fits their needs.
