The shape, proportion, or overall appearance of the face and body can be enhanced through cosmetic surgery. For some people, it can also reduce concern about a physical feature that has caused distress for years. Even so, all operations involve some uncertainty. Understanding the risks of cosmetic surgery is an essential part of deciding whether a procedure is right for you.
Although most patients heal without serious problems, no surgeon can guarantee perfection or eliminate every surgical risk. Complications may result from anesthetic medication, bleeding, infection, delayed healing, unexpected reactions, or an individual response to surgery. Certain complications are short-lived and can be treated without major intervention. In other cases, a complication can require drugs, hospital care, another operation, or extended monitoring.
In Canada, patients should be clearly informed about expected benefits, important risks, treatment alternatives, recovery needs, and what may happen if they decline surgery. 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.
What Risks Can Cosmetic Surgery Involve?
The risks of cosmetic surgery include unwanted outcomes that affect health, physical function, or appearance. The procedure being performed, technique used, body area treated, duration of surgery, anesthesia method, and patient health all influence risk.
Many cosmetic procedures are followed by mild expected side effects. Swelling, bruising, soreness, numbness, tightness, fatigue, and mild drainage may be normal during early healing. 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:
- Bleeding or a collection of blood called a hematoma
- Infection at the incision or within deeper tissue
- Fluid buildup, known as a seroma
- Blood clots in the legs or lungs
- Slow wound healing or separation of the incision
- Scars that become prominent, raised, wide, or uneven
- Nerve-related problems, including numbness or unusual sensation
- Tissue damage or loss resulting from inadequate blood flow
- Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials
- Unevenness, contour irregularities, or an unsatisfactory appearance
- Changes in function, such as breathing, movement, or sensation
- The need for additional treatment or revision surgery
Major complications do not happen often, but patients should understand that they remain possible. Uncommon but severe risks can include serious infection, substantial bleeding, damage to an organ, cardiac complications, stroke, pulmonary embolism, lasting disability, or death.
Expected Short-Term Effects of Cosmetic Surgery
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.
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. 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.
Swelling and Bruising
Inflammation and the movement of fluid into surgical tissues cause swelling. For several weeks or even months, swelling may conceal the true result of surgery. Bruises form when tiny blood vessels are damaged and blood collects beneath the skin. Patients undergoing face surgery, breast surgery, liposuction, or body contouring may experience noticeable bruising and swelling.
The outcome of surgery should not be assessed before healing has progressed. Residual swelling can change shape, symmetry, and skin texture during recovery.
Changes in Feeling After Surgery
During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Temporary numbness, tingling, sensitivity, or reduced feeling is common after some operations. Feeling frequently returns as the nerves heal, although full recovery is not certain. 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. Restrictions may apply to driving, physical activity, lifting, swimming, and work. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored.
Potential Surgical Complications
Postoperative Bleeding and Hematoma
Minor bleeding near a surgical incision can occur during early recovery. More significant bleeding can form a hematoma, which is a collection of blood beneath the skin or inside the surgical area. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
Some hematomas can be observed, while others must be drained. Some hematomas require another operation to control the bleeding and remove collected blood.
Infection After Cosmetic Surgery
The incision, nearby skin, deeper surgical tissues, or an implant pocket can become infected. An infection may cause increasing warmth, redness, swelling, pain, discharge resembling pus, fever, chills, or a bad smell.
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. Smoking, uncontrolled diabetes, poor nutrition, and problems with blood circulation can raise the risk of infection or make it harder to treat.
Postoperative Seroma
Clear fluid that gathers beneath the skin is known as a seroma. 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.
The body may gradually absorb a small seroma without further treatment. Larger ones may need to be drained, sometimes more than once. If fluid is not treated, it may strain the incision, delay healing, or lead to infection.
Deep Vein Thrombosis and Pulmonary Embolism
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. 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. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable.
Delayed or Difficult Wound Healing
Slow healing or separation of the incision can occur after cosmetic surgery. Reduced blood supply, infection, tension on the wound, nicotine exposure, certain medications, and medical conditions can interfere with healing.
Wound problems may require dressings, antibiotics, removal of damaged tissue, or additional surgery. When a wound is left to close slowly from its deeper layers toward the surface, the process is called healing by secondary intention. The recovery period may be extended, and the final scar may be more prominent.
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 and nicotine use are major preventable risk factors because nicotine narrows blood vessels and reduces oxygen delivery.
Management of necrosis varies according to the cosmetic surgeons near me 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.
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.
Anesthesia may be associated with the following risks:
- Postoperative nausea or vomiting
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- Throat discomfort or headache
- An allergic response or adverse drug reaction
- Fluctuations in blood pressure or disturbances in heartbeat
- Breathing difficulties
- Aspiration of stomach contents into the lungs
- Dental, lip, or airway damage
- Serious heart, lung, or neurological complications
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. Withholding medical or lifestyle information may increase the risks of anesthesia and surgery.
Changes in Scarring, Colour, and Skin Texture
A surgical procedure that breaks the skin will always leave some degree of scarring. Incisions are often positioned in natural creases, along hairlines, or beneath clothing, although no scar can be removed entirely.
During the first stages of healing, scars may look red, thick, firm, elevated, or darker than nearby skin. They may soften and fade over 12 months or longer. 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. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. A history of hypertrophic scars or keloids, whether personal or familial, should be discussed before an operation.
Raised or visible scars may be treated with silicone, compression, copyright injections, laser procedures, or surgical 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
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. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
Aesthetic Risks and Unsatisfactory Results
A procedure can be medically and technically successful while still producing a result the patient did not anticipate. 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:
- Persistent asymmetry
- Visible dents, bulges, or contour differences
- A result that is under-treated or over-treated
- An unnatural or overly tight appearance
- Alterations in shape while swelling resolves
- Movement or poor positioning of an implant
- Visible or poorly placed scars
- A return of looseness or sagging with age and time
- Patient dissatisfaction even when the result is medically acceptable
Before-and-after images, photographs, and computer simulations may help explain possibilities, but they do not promise a matching result. Anatomy and healing responses vary from one person to another.
Corrective and Revision 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.
Patients should ask what the clinic's revision policy covers. Additional costs for the surgeon, operating room, anesthetic, implants, medicine, transportation, accommodation, and missed employment may fall outside the initial price.
Complications by Type of Cosmetic Surgery
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Possible Facelift and Neck Lift Complications
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. Smoking, vaping, and other nicotine exposure can significantly raise the chance of skin loss and delayed healing.
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. It can take at least a year for swelling to resolve enough for the final nasal shape to be assessed. Scar formation and altered cartilage can make secondary rhinoplasty more complex.
Eyelid Surgery Risks
Blepharoplasty risks include dry or irritated eyes, temporary blurred vision, difficulty closing the eyelids, eyelid malposition, asymmetry, scarring, bleeding behind the eye, and changes in vision. Severe eye pain or a sudden change in vision requires urgent medical assessment.
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. Other risks include hematoma, infection, fat necrosis, delayed healing, and changes in nipple or areola position.
Patients with breast implants face additional concerns that can develop over time. 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 also provides safety information about uncommon conditions linked with certain breast implants, including breast implant-associated anaplastic large cell lymphoma.
Risks of Liposuction
Liposuction may lead to dents, surface irregularities, skin looseness, fluid problems, numbness, fluid collection, infection, organ injury, fat embolism, or lidocaine toxicity when local anesthesia is involved. High-volume liposuction and treatment of several regions can place greater stress on the body and make recovery more demanding.
Possible Tummy Tuck and Body Lift Complications
Large sections of skin and underlying tissue are moved during abdominoplasty and body lift surgery. Risks include seroma, blood clots, infection, skin loss, wound separation, numbness, prominent scarring, and changes to the position or shape of the belly button. Activity and lifting restrictions can remain in place for a number of weeks.
Possible Fat Grafting Complications
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. Fat grafting may also cause fat necrosis, cyst formation, calcium deposits, infection, oily fluid collections, or unintended injection into circulation. Fat transfer risks vary according to whether the treatment area is the face, breast, buttocks, or another body region.
Who Has a Higher Risk of Complications?
Some health and lifestyle factors can raise the chance of complications. A patient may need medical testing, treatment changes, weight management, nicotine cessation, or clearance from another health professional before surgery.
Factors associated with higher surgical risk include:
- Cigarette smoking, vaping, or any form of nicotine use
- Poorly controlled diabetes
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A clotting or bleeding condition, or previous blood clots
- Obesity or major weight changes
- A diagnosed or suspected sleep-related breathing disorder
- Conditions affecting the immune system
- Poor nutrition or significant anemia
- Scar tissue or circulation changes from prior operations or radiation
- Drugs, vitamins, or supplements that interfere with clotting or tissue repair
- Unrealistic expectations or untreated mental health concerns that affect decision-making
The presence of one or more risk factors does not automatically prevent cosmetic surgery. Instead, the surgeon must assess whether surgery is reasonably safe and determine what preparation is required.
Psychological and Emotional Risks
The effects of cosmetic surgery may be psychological and emotional, not only physical. Swelling, bruising, fatigue, and temporary lifestyle restrictions may leave some patients feeling worried, frustrated, or low. 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.
The patient's motivation for considering surgery should be discussed during an appropriate assessment. 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 causes significant distress and preoccupation with appearance flaws that may seem minor or unnoticeable to others. Surgery may not relieve the underlying concern. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation.
Ways to Lower Cosmetic Surgery Risks
Although no operation can be made completely risk-free, thorough preparation can improve safety.
- Work with a properly trained physician whose practice includes the cosmetic operation you are considering.
- 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.
- Disclose your entire health history, including previous surgery, allergies, medications, supplements, alcohol, cannabis, and nicotine use.
- Carefully follow all directions related to eating, drinking, preoperative tests, medication adjustments, and nicotine cessation.
- Arrange a responsible adult to drive you home and assist during early recovery when required.
- 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.
- Wait until healing is mature before deciding whether revision surgery is needed.
Choosing a Cosmetic Surgeon in Canada
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.
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.
During the consultation, patients may wish to ask:
- What are your surgical qualifications and specialty credentials?
- How often do you perform this procedure?
- Does my medical history and physical anatomy make me an appropriate candidate?
- What complications are seen most frequently with this procedure 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?
- What emergency plan is in place if I need urgent medical treatment?
- Which follow-up visits and services are included in the fee?
- What costs could arise if I need treatment or revision surgery?
What Informed Consent Should Include
Informed consent involves more than placing a signature on a document. It is an ongoing discussion that should give the patient enough information to make a voluntary decision.
The consent process should cover the nature of the procedure, expected benefits, important risks, reasonable alternatives, recovery, limitations, and what could happen without treatment. Any complication that could significantly affect the patient's medical condition, employment, lifestyle, or priorities should receive special attention.
No one should be pushed into signing a surgical consent form quickly. 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. The surgical team should be contacted quickly if symptoms become worse, appear unusual, or do not match the expected healing process.
Potential emergency signs after cosmetic surgery include:
- Chest pain, shortness of breath, coughing blood, or fainting
- Sudden swelling, pain, redness, or warmth in one leg
- Significant bleeding or swelling that expands quickly
- Severe pain that is not controlled by prescribed medication
- High fever, chills, spreading redness, or pus-like drainage
- Confusion, extreme weakness, or difficulty staying awake
- Skin that becomes very pale, dark, blistered, or cold to the touch
- Sudden vision loss, severe eye pain, or major visual changes
- Persistent vomiting that prevents normal hydration
- A symptom listed as urgent in the postoperative instructions
When a symptom could represent a life-threatening emergency, call 911 or go to an emergency department. Severe breathing difficulty, chest pain, unconsciousness, heavy bleeding, and other emergency symptoms should not wait until normal clinic hours.
Financial Risks and Health Coverage in Canada
Canadian provincial and territorial health plans generally do not pay for operations performed solely for cosmetic reasons. 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.
Anyone travelling outside Canada for cosmetic surgery should arrange appropriate postoperative care before coming home. Lower upfront fees may become more expensive if postoperative infection, wound breakdown, clotting, implant complications, or revision treatment is required.
Evaluating the Advantages 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. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection.
Patients should carefully weigh likely improvements against health risks, emotional effects, recovery demands, and financial costs. Think about your ability to obey postoperative instructions, live with scars, take enough time off, and emotionally manage an outcome that is not ideal.
A qualified surgeon may advise against a procedure when the risk is too high, the expected benefit is limited, or the patient's goals cannot be achieved safely. A decision not to operate is sometimes the safest and most responsible form of patient care.
Deciding Whether Cosmetic Surgery Is Right for You
Learning about cosmetic surgery risks does not mean expecting that something will go wrong. Instead, risk awareness allows patients to decide using reliable facts rather than marketing, online trends, or cost as the only factor.
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.
