Through cosmetic surgery, patients may change the shape, proportions, or appearance of their face or body. It may also help a person feel more comfortable with a feature that has bothered them for years. However, every operation involves some degree of uncertainty. Understanding the risks of cosmetic surgery is an important 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. 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 thorough consultation should provide enough time to review the information and make a decision 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.
Understanding the Risks of Cosmetic Surgery
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.
Minor side effects are expected after many procedures. During early recovery, swelling, bruising, tenderness, numbness, tightness, tiredness, and light drainage may be normal. Expected healing effects and surgical complications are different. A complication extends beyond normal recovery and may need medical care.
Possible complications of plastic surgery include:
- A hematoma, which is a collection of blood, or other excessive bleeding
- Infection at the incision or within deeper tissue
- A collection of fluid called a seroma
- Blood clots affecting the legs or lungs
- An incision that heals poorly, slowly, or begins to open
- Scars that become prominent, raised, wide, or uneven
- Nerve injury, numbness, or altered sensation
- Loss of skin, fat, or other tissue because of reduced circulation
- Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products
- Asymmetry, contour problems, or an unwanted appearance
- Functional changes affecting breathing, movement, or feeling
- A need for further care or corrective surgery
Although serious complications are rare, they must still be reviewed before surgery. Uncommon but severe risks can include serious infection, substantial bleeding, damage to an organ, cardiac complications, stroke, pulmonary embolism, lasting disability, or death.
Common Early Effects During Cosmetic Surgery Recovery
Some discomfort and physical change are part of normal healing. Patients who understand expected recovery are better able to separate routine symptoms from possible complications.
Postoperative Pain and Tenderness
Pain levels vary by procedure and patient. Patients may notice aching, tightness, burning, or tenderness around the treated area. Discomfort is normally expected to improve gradually during healing. 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
Inflammation and the movement of fluid into surgical tissues cause swelling. The early result can remain difficult to assess until swelling subsides over the following 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 are advised to avoid making early judgments about their final appearance. Residual swelling can change shape, symmetry, and skin texture during recovery.
Changes in Feeling After Surgery
Small sensory nerves may be stretched, moved, or cut during surgery. Temporary numbness, tingling, sensitivity, or reduced feeling is common after some operations. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. There is a possibility that altered feeling will not fully resolve.
Activity Limitations During Recovery
During early recovery, patients may require support with transportation, meals, family duties, pets, household chores, and self-care. Restrictions may apply to driving, physical activity, lifting, swimming, and work. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Surgical and Medical Complications
Bleeding or Blood Collection
A limited amount of bleeding around the incision may be expected. Heavier bleeding may create a hematoma, a pocket of blood beneath the skin or within the treated area. Increasing tenderness, firmness, swelling, discolouration, or an abrupt difference between two sides may indicate a hematoma.
Some hematomas can be observed, while others must be drained. Some hematomas require another operation to control the bleeding and remove collected blood.
Infection
An infection can develop in the skin, incision, tissue, or around an implant. Warning signs can include spreading redness, heat, swelling, worsening pain, pus-like fluid, fever, chills, or an unusual odour.
Antibiotics, specialized wound care, drainage, or further surgery may be needed to treat an infection. Removal can be required when infection develops around a breast implant or surgical device. Infection risk and treatment difficulty may increase with smoking, poorly controlled diabetes, inadequate nutrition, or reduced circulation.
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.
A minor fluid collection can sometimes disappear as the body reabsorbs it. Repeated drainage may be necessary when a significant seroma develops. Untreated fluid can place pressure on the incision, affect healing, or become infected.
Deep Vein Thrombosis 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. If part of the clot travels to the lungs, it can cause a pulmonary embolism. A pulmonary embolism requires emergency medical care.
Long procedures, inactivity, earlier blood clots, some drugs, nicotine use, excess body weight, health conditions, and combined operations can increase the chance of DVT or pulmonary embolism. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate.
Delayed or Difficult Wound Healing
A surgical wound may take longer than expected to close or may start to open. Reduced blood supply, infection, tension on the wound, nicotine exposure, certain medications, and medical conditions can interfere with healing.
Incision problems may need wound care, antibiotics, surgical cleaning, or further corrective surgery. 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.
Loss of Tissue From Poor Blood Supply
When skin, fat, or other tissue loses its blood supply and starts to die, the condition is called necrosis. Operations that move, tighten, or lift broad areas of tissue can carry a risk of necrosis. Smoking and nicotine use are major preventable risk factors because nicotine narrows blood vessels and reduces oxygen delivery.
Management of necrosis varies according to the size and depth of the affected area. It may involve wound care, removal of damaged tissue, skin grafting, reconstructive surgery, or a delayed revision.
Risks Related to Anesthesia
Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. 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:
- Nausea and vomiting
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- Headache or sore throat
- Allergic or medication reactions
- Fluctuations in blood pressure or disturbances in heartbeat
- Breathing difficulties
- Stomach contents entering the lungs, known as aspiration
- Dental, lip, or airway damage
- 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. 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. Over 12 months or longer, scar tissue can gradually fade and soften. Genetic factors, skin characteristics, pressure on the incision, infection, sunlight, wound care, surgical location, and procedure type all influence the finished scar.
Hypertrophic and Keloid Scarring
A hypertrophic scar becomes thick or raised but stays within the original wound. A keloid grows beyond the borders of the incision. People with a personal or family history of abnormal scarring should tell their surgeon before surgery.
Treatment options can include silicone sheets or gels, pressure treatment, corticocopyright injections, laser therapy, and 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
Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. Alterations in colour or texture may improve, but they can also remain long term. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
The Risk of an Unwanted Cosmetic Result
Even when surgery is performed correctly, the final appearance may not match the patient's expectations. 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
- Visible dents, bulges, or contour differences
- 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
- 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. Anatomy and healing responses vary from one person to another.
Revision Cosmetic Surgery
Revision surgery may be considered when a complication occurs or when the result can be improved. Revision surgery carries risks of its own. Because scarred tissues may be less flexible and have reduced circulation, revision procedures can be more difficult.
It is important to ask how the practice handles revisions and which expenses are covered. Additional costs for the surgeon, operating room, anesthetic, implants, medicine, transportation, accommodation, and missed employment may fall outside the initial price.
Complications by Type of Cosmetic Surgery
General surgical risks apply to many operations, but each procedure also has unique concerns.
Possible Facelift and Neck Lift Complications
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.
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. A revision nose operation is often more challenging because the first surgery changes the cartilage and creates internal scarring.
Possible Complications of Eyelid Surgery
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.
Possible Breast Procedure Complications
Breast augmentation, breast lift, and breast reduction may affect nipple sensation, breast symmetry, scar appearance, and the ability to breastfeed. Hematoma, infection, fat necrosis, poor healing, and altered nipple or areola position are also possible.
Breast implants bring added long-term considerations. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. Patients should not assume that breast implants will remain in place permanently without further care. Health Canada publishes safety guidance concerning rare illnesses associated with some breast implants, including breast implant-associated anaplastic large cell lymphoma.
Liposuction Risks
Possible problems after liposuction include uneven contours, indentations, rippled or loose skin, changes in fluid balance, reduced feeling, seroma, infection, internal damage, fat embolism, and toxicity from lidocaine. Removing larger volumes of fat or treating several body areas may increase medical stress and recovery demands.
Risks of Abdominoplasty and Body Lift Surgery
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. 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.
Fat Grafting Risks
Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. Some of the transferred fat will be absorbed, which can affect volume and symmetry. 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 May Face Greater Cosmetic Surgery Risks?
Some health and lifestyle factors can raise the chance of complications. Before proceeding, some patients require tests, adjustments to treatment, weight changes, nicotine cessation, or approval from another medical professional.
Risk factors may include:
- Cigarette smoking, vaping, or any form of nicotine use
- Poorly controlled diabetes
- Heart, lung, kidney, liver, or blood vessel disease
- 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 disorders or reduced immune function
- Nutritional deficiencies or a low red blood cell count
- 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
The presence of one or more risk factors does not automatically prevent cosmetic surgery. 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
An operation performed for appearance can influence a patient's mental and emotional state in addition to the body. 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.
Significant dissatisfaction is more likely when the expected transformation is not medically achievable. Cosmetic surgery may change a physical feature, but it cannot guarantee confidence, repair a relationship, create career success, or solve broader personal problems.
A responsible assessment should explore the patient's reasons for seeking surgery. 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. Changing the physical feature does not necessarily treat the underlying mental health condition. A psychological evaluation or professional support may be recommended before surgery when concerns are identified.
How to Reduce the Risks of Cosmetic Surgery
Although no operation can be made completely risk-free, thorough preparation can improve safety.
- Select a qualified doctor who has appropriate education and substantial experience performing 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.
- Do not schedule travel, work duties, exercise, or major events until you understand how long recovery may take.
- 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.
- Wait until healing is mature before deciding whether revision surgery is needed.
How to Select a Cosmetic Surgeon in Canada
Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. Patients 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. 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.
During the consultation, patients may wish to ask:
- What professional education and certifications have you completed?
- How often do you perform this procedure?
- Am I a suitable candidate based on my health and anatomy?
- Which problems do your patients experience most often after this operation?
- Which uncommon but severe complications need to be considered?
- Who is responsible for anesthesia care during the operation?
- Who should I contact if I experience a complication outside normal clinic hours?
- Which hospital or emergency facility would treat me if a serious problem occurred?
- What follow-up visits are included?
- Which additional expenses would I be responsible for if a complication or revision occurs?
What Informed Consent Should Include
Informed consent involves more than placing a signature on a document. The process requires clear communication so that the patient can make a knowledgeable and voluntary choice.
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 plastic surgery near me priorities should receive special attention.
A patient should never feel rushed to sign. When medical language or a possible complication is confusing, the patient should request a clearer explanation. 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
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.
Potential emergency signs after cosmetic surgery include:
- Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness
- Unexpected pain, swelling, redness, or heat affecting one leg
- Heavy bleeding or rapidly increasing swelling
- Severe pain that is not controlled by prescribed medication
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Confusion, extreme weakness, or difficulty staying awake
- 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
- Any problem your surgeon specifically described as requiring emergency care
Call 911 or seek emergency care when symptoms may be life-threatening. 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. Out-of-pocket expenses may include the surgeon, anesthesia provider, operating room, medical devices, recovery clothing, prescriptions, laboratory work, and follow-up items.
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.
Patients considering medical tourism should think about who will provide follow-up care after returning to Canada. An inexpensive overseas package may exclude the cost of treating infection, poor healing, DVT, implant problems, and corrective operations.
Weighing Cosmetic Surgery Benefits Against Risks
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.
Take time to compare the expected benefit with the medical, emotional, practical, and financial risks. Consider whether you can follow the recovery plan, accept visible scars, manage time away from work, and cope with the possibility of an imperfect result.
A responsible surgeon may decline surgery if the patient's risk level is unacceptable, the likely improvement is minimal, or the desired result is unrealistic. 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. It means making a thoughtful decision based on accurate information rather than advertising, social media trends, or price alone.
Before surgery, research the operation, assess your health risks, verify medical credentials, ask thorough questions, and prepare for the complete healing period. When the benefits, limits, alternatives, and possible complications are understood, patients are better prepared to decide whether cosmetic surgery fits their needs.
