Cosmetic surgery can improve 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. Even so, every surgical procedure involve some uncertainty. Understanding the risks of cosmetic surgery is an important part of deciding whether a procedure is right for you.
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 complications are temporary and easy to treat. 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. 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 type and level of risk depend on the procedure, the surgical technique, the area being treated, the length of the operation, the form of anesthesia, and the patient's overall health.
It is normal for patients to experience some minor effects after many operations. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. A complication is different. It is a problem that goes beyond the expected recovery process and may require medical treatment.
Potential problems associated with plastic surgery include:
- A hematoma, which is a collection of blood, or other excessive bleeding
- An infection in the incision or deeper surgical tissues
- Fluid buildup, known as a seroma
- Blood clots in the legs or 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
- Loss of skin, fat, or other tissue because of reduced circulation
- 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
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 Early Effects During Cosmetic Surgery Recovery
Some discomfort and physical change are part of normal healing. Knowing what normal healing looks like helps patients recognize when a symptom may be a warning sign.
Postoperative Pain and Tenderness
Each patient experiences pain differently, and some operations cause more discomfort than others. The surgical site can feel tender, tight, sore, or mildly burning during recovery. 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
Swelling is caused by inflammation and fluid moving into the treated tissues. It may hide the initial surgical result for weeks or months. Bruises form when tiny blood vessels are damaged and blood collects beneath the skin. Visible bruising and swelling may follow facial surgery, liposuction, breast procedures, or body contouring.
Patients should not judge the final result too early. Remaining swelling may temporarily affect shape, balance, and the texture of the skin.
Numbness and Changes in Sensation
Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. Temporary numbness, tingling, sensitivity, or reduced feeling is common after some operations. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. Permanent sensory changes are possible.
Activity Limitations During Recovery
Patients may need help with transportation, meals, child care, pet care, household work, and personal tasks. Driving, exercise, heavy lifting, swimming, and returning to work may be restricted. Failing to follow activity restrictions may raise the risk of bleeding, swelling, wound breakdown, and other problems.
Potential Surgical Complications
Postoperative Bleeding and Hematoma
A small amount of bleeding may occur around an incision. 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.
A small hematoma may only need monitoring, but a larger one may require drainage. In certain cases, the patient may need to return to the operating room.
Infection
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.
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.
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.
Small seromas may resolve as the body absorbs the fluid. 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.
Blood Clots and Pulmonary Embolism
A blood clot that non-surgical cosmetic surgery forms in a deep vein, commonly within the leg, is called deep vein thrombosis, or DVT. When part of a deep vein clot moves into the lungs, it may block blood flow and cause a pulmonary embolism. A pulmonary embolism requires emergency medical care.
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. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate.
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.
Wound problems may require dressings, antibiotics, removal of damaged tissue, or additional 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.
Loss of Tissue From Poor Blood Supply
Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and die. Operations that move, tighten, or lift broad areas of tissue can carry a risk of necrosis. Smoking, vaping, and other nicotine use can greatly increase risk by narrowing blood vessels and reducing tissue oxygen.
The extent of tissue damage determines which treatment is required. Possible treatment includes wound management, removal of dead tissue, a skin graft, reconstructive surgery, or revision at a later date.
Anesthesia Risks in Cosmetic Surgery
Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. The most suitable anesthesia plan is based on the type of surgery, patient health history, procedure duration, and location where surgery takes place.
Anesthesia may be associated with the following risks:
- Postoperative nausea or vomiting
- Dizziness, confusion, or prolonged drowsiness
- Headache or sore throat
- Allergic or medication reactions
- Abnormal blood pressure or irregular heart rhythm
- Respiratory difficulty
- Aspiration, which occurs when material from the stomach reaches the lungs
- Injury to the teeth, lips, mouth, or airway
- Major complications involving the heart, lungs, or nervous system
Patients must provide 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
Any procedure that cuts the skin creates a scar. 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.
Raised Scars and Keloid Formation
A hypertrophic scar becomes thick or raised but stays within the original wound. A keloid grows beyond the borders of the incision. A history of hypertrophic scars or keloids, whether personal or familial, should be discussed before an operation.
Possible treatments include silicone products, pressure therapy, copyright injections, laser treatment, or scar revision. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return.
Changes in Skin Colour and Texture
Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. These effects may be temporary or permanent. The risk can differ by skin tone and by the type of procedure performed.
The Risk of an Unwanted Cosmetic Result
Even when surgery is performed correctly, the final appearance may not match the patient's expectations. 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
- Visible dents, bulges, or contour differences
- 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
- A return of looseness or sagging with age and time
- Disappointment with an outcome that falls within an acceptable surgical range
Photos, digital simulations, and before-and-after galleries can support discussion, but they cannot guarantee an identical outcome. Each patient has different anatomy and heals in a different way.
The Possibility of Revision Surgery
A corrective operation may be discussed if a complication develops or if the original result could be refined. Revision surgery carries risks of its own. 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.
Patients should ask what the clinic's revision policy covers. 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
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.
Risks of Nose Surgery
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
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.
Possible Breast Procedure Complications
Procedures such as breast augmentation, mastopexy, and breast reduction can change nipple feeling, breast balance, scarring, and future breastfeeding ability. Other risks include hematoma, infection, fat necrosis, delayed healing, and changes in nipple or areola position.
Breast implants bring added long-term considerations. These include capsular contracture, implant rupture, deflation, rippling, movement, rotation, pain, and the need for future monitoring or surgery. Implants are not lifetime devices. Health Canada publishes safety guidance concerning rare illnesses associated with some breast implants, including breast implant-associated anaplastic large cell lymphoma.
Liposuction Risks
Liposuction may lead to dents, surface irregularities, skin looseness, fluid problems, numbness, fluid collection, infection, organ injury, fat embolism, or lidocaine toxicity when local anesthesia is involved. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated.
Tummy Tuck and Body Lift Risks
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. Patients may need several weeks of movement restrictions.
Possible Fat Grafting Complications
Fat transfer involves removing fat from one area and injecting it into another. The body naturally absorbs some transferred fat, potentially reducing volume or creating asymmetry. 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?
A patient's health status and daily habits may make complications more likely. Before proceeding, some patients require tests, adjustments to treatment, weight changes, nicotine cessation, or approval from another medical professional.
Factors associated with higher surgical risk include:
- Smoking, vaping, or using nicotine products
- Poorly controlled diabetes
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A bleeding disorder or history of blood clots
- Obesity or major weight changes
- A diagnosed or suspected sleep-related breathing disorder
- Immune disorders or reduced immune function
- 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
- Mental health concerns or unrealistic goals that interfere with informed decision-making
A higher-risk medical history does not necessarily make an operation unsuitable. Instead, the surgeon must assess whether surgery is reasonably safe and determine what preparation is required.
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. The term postoperative blues is sometimes used to describe this temporary decline in mood.
More serious dissatisfaction can occur when expectations do not match what surgery can realistically achieve. A cosmetic procedure can modify the body, but it does not guarantee emotional confidence, relationship improvement, career advancement, or solutions to unrelated personal concerns.
A responsible assessment should explore the patient's reasons for seeking surgery. Concerns may arise when someone is being pressured, remains unhappy after repeated procedures, is intensely focused on a small flaw, or expects surgery to change every part of life.
Intense and persistent concern about perceived physical defects may be a sign of body dysmorphic disorder, a recognized mental health condition. An operation may fail to resolve the deeper psychological distress. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation.
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.
- Check the doctor's licence, registration, and professional standing with the applicable provincial or territorial medical regulator.
- 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.
- When needed, organize transportation and early postoperative support from a responsible adult.
- Do not schedule travel, work duties, exercise, or major events until you understand how long recovery may take.
- Attend all follow-up appointments and report unusual symptoms promptly.
- Do not compare your healing speed with edited images or another patient's recovery.
- 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. Royal College certification is valuable, but it should be considered alongside relevant experience, patient communication, emergency planning, surgical environment, and postoperative support.
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?
- Does my medical history and physical anatomy make me an appropriate candidate?
- What are the most common complications in your practice?
- What rare but serious risks should I understand?
- Which medical professional will administer and monitor my anesthesia?
- What happens if I have a complication after business hours?
- Where would I receive emergency care if needed?
- What follow-up visits are included?
- What costs could arise if I need treatment or revision surgery?
Informed Consent for Cosmetic Surgery
Informed consent involves more than placing a signature on a document. 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. The surgeon should also explain risks that may have particular importance because of the patient's occupation, health, daily activities, or individual goals.
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
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
- A significant fever, shaking chills, expanding redness, or thick discharge
- Disorientation, marked weakness, or excessive drowsiness
- Skin that becomes very pale, dark, blistered, or cold to the touch
- Loss of sight, intense eye pain, or an abrupt disturbance in vision
- Repeated vomiting or an inability to keep fluids down
- A symptom listed as urgent in the postoperative instructions
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.
Financial Considerations for Cosmetic Surgery in Canada
When a procedure is intended only to improve appearance, public health insurance in Canada will usually not cover it. Patients usually pay for the surgeon, anesthesia, operating facility, implants, garments, prescriptions, testing, and other related expenses.
Complication-related costs should be discussed before surgery. Health coverage for complications varies based on medical necessity, treatment setting, and the applicable provincial or territorial insurance plan. Travel, accommodation, nursing assistance, missed work, child care, and revision surgery can create additional expenses.
Medical tourists need to determine which Canadian provider, if any, will manage recovery and complications after their return. An inexpensive overseas package may exclude the cost of treating infection, poor healing, DVT, implant problems, and corrective operations.
Balancing the Benefits and Risks of Cosmetic Surgery
A sound decision about cosmetic surgery requires realistic expectations, appropriate health, informed consent, and knowledge of the healing process. A suitable patient recognizes that improvement is possible, but perfection is not.
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.
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. The goal is to make a careful choice based on medical information, not promotional claims, social media influence, or the lowest price.
A safer decision involves understanding the procedure, identifying individual risk factors, checking the surgeon's qualifications, discussing concerns, and organizing postoperative care. When the benefits, limits, alternatives, and possible complications are understood, patients are better prepared to decide whether cosmetic surgery fits their needs.
