The shape, proportion, or overall appearance of the face and body can be improved through cosmetic surgery. It may also help a person feel more comfortable with a feature that has bothered them for years. However, every operation involves uncertainty. Understanding the risks of cosmetic surgery is an important part of deciding whether a procedure is right for you.
Most patients recover without a major complication, but no surgeon can promise a perfect result or a risk-free operation. Problems can occur because of anesthesia, bleeding, infection, poor healing, an unexpected reaction, or the way the body responds to surgery. Some problems resolve with simple treatment and do not cause lasting harm. 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. During a careful consultation, patients should be able to consider the facts without being rushed. 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?
The risks of cosmetic surgery include unwanted outcomes that affect health, physical function, or appearance. 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.
Many cosmetic procedures are followed by mild expected side effects. 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.
Potential problems associated with plastic surgery include:
- A hematoma, which is a collection of blood, or other excessive bleeding
- Infection at the incision or within deeper tissue
- Seroma formation, which involves fluid collecting beneath the tissue
- Blood clots affecting the legs or lungs
- An incision that heals poorly, slowly, or begins to open
- Noticeable, raised, widened, or uneven scars
- Nerve injury, numbness, or altered 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
- Functional changes affecting breathing, movement, or feeling
- The need for additional treatment or revision surgery
Serious complications are uncommon, but they are still important to discuss. Possible rare complications include severe infection, major hemorrhage, organ damage, heart problems, stroke, a blood clot in the lungs, permanent impairment, and death.
Common Short-Term Effects After 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.
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. Patients should quickly report severe or spreading pain, especially when it is accompanied by fever, redness, shortness of breath, or unusual swelling.
Bruising and Tissue Swelling
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. 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 not be assessed before healing has progressed. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Numbness and Changes in Sensation
Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. Temporary changes such as tingling, numbness, tenderness, or reduced sensation may occur after surgery. Nerve recovery often improves sensation over time, but normal feeling may not return completely. Permanent sensory changes are possible.
Activity Limitations During Recovery
Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. Driving, exercise, heavy lifting, swimming, and returning to work may be restricted. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored.
Medical and Surgical Risks
Bleeding or Blood Collection
Minor bleeding near a surgical incision can occur during early recovery. 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.
Surgical Infection
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.
Fluid Buildup or Seroma
A seroma develops when a pocket of clear fluid forms under the surgical tissues. Procedures such as abdominoplasty, body lift surgery, breast surgery, and large-area liposuction may have a greater seroma risk because they create space beneath the tissue.
The body may gradually absorb a small seroma without further treatment. A larger seroma may require drainage on one or several occasions. A persistent seroma can create pressure, interfere with wound healing, and increase the chance of infection.
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. A pulmonary embolism requires emergency medical care.
Risk may increase with long operations, limited movement, previous blood clots, certain medications, nicotine use, obesity, some medical conditions, and combining multiple procedures. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate.
Problems With Incision Healing
Slow healing or separation of the incision can occur after cosmetic surgery. 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. Healing by secondary intention means allowing an open area to close gradually from the inside outward. Healing in this way often takes more time and can result in a more noticeable scar.
Skin or Tissue Necrosis
Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and die. Tissue loss may occur after procedures involving extensive lifting, tightening, or repositioning. Nicotine exposure is an important avoidable risk because it constricts blood vessels and limits oxygen reaching the tissues.
The extent of tissue damage determines which treatment is required. It may involve wound care, removal of damaged tissue, skin grafting, reconstructive surgery, or a delayed revision.
Risks Related to Anesthesia
Local anesthesia, sedation, general anesthesia, or a combination may be used during cosmetic surgery. Choosing an anesthesia method requires consideration of the operation, medical background, expected surgical time, and facility.
Potential complications connected with anesthesia include:
- Postoperative nausea or vomiting
- Dizziness, confusion, or prolonged drowsiness
- Headache or sore throat
- Allergic or medication reactions
- Fluctuations in blood pressure or disturbances in heartbeat
- Breathing difficulties
- Aspiration, which occurs when material from the stomach reaches the lungs
- 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. The safety of the operation can be reduced when important health information is omitted.
Scarring and Changes to the Skin
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.
Early scars can be firm, raised, reddish, or more deeply coloured before they mature. They may soften and fade over 12 months or longer. The final appearance depends on genetics, skin type, incision tension, infection, sun exposure, wound care, location, and the type of operation.
Hypertrophic and Keloid Scarring
Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. A keloid grows beyond the borders of the incision. Patients should inform their surgeon if they or close family members have developed raised or unusual scars.
Treatment options can include silicone sheets or gels, pressure treatment, corticocopyright injections, laser therapy, and scar revision. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return.
Pigment and Texture Irregularities
The treated skin may develop colour changes, redness, noticeable blood vessels, dimpling, firmness, or textural differences. Some of these changes resolve over time, while others can last permanently. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
The Risk of an Unwanted Cosmetic Result
A technically successful operation does not always produce the appearance a patient expected. The body's response is shaped by age, anatomy, skin quality, earlier surgery, scar development, and normal side-to-side differences.
Appearance-related problems may include:
- Persistent asymmetry
- Irregular or uneven body contours
- 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
- Noticeable scars or scars in an unfavourable location
- 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. Every patient's tissues, proportions, and recovery process are unique.
Revision Cosmetic Surgery
When problems occur or the outcome may benefit from improvement, revision cosmetic surgery can be considered. 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.
Before proceeding, patients should understand exactly what is included in the surgeon's or clinic's revision policy. The first surgical fee may not cover a revision surgeon, facility charges, anesthesia, new implants, prescriptions, travel, or lost work time.
Procedure-Specific Cosmetic Surgery Risks
Although many operations share common complications, every cosmetic procedure has its own specific risks.
Facelift and Neck Lift Risks
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. Smoking, vaping, and other nicotine exposure can significantly raise the chance of skin loss and delayed healing.
Risks of Nose Surgery
Potential rhinoplasty complications include long-lasting swelling, bleeding, infection, unevenness, altered smell, contour problems, a hole in the septum, structural collapse, and nasal breathing difficulty. 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.
Eyelid Surgery Risks
After blepharoplasty, patients may develop dry eyes, irritation, blurred vision, trouble shutting the eyelids, lid malposition, asymmetry, scarring, orbital bleeding, or changes in eyesight. Severe eye pain or a sudden change in vision requires urgent medical assessment.
Possible Breast Procedure Complications
Nipple sensation, symmetry, scars, and the ability to breastfeed may be affected by breast augmentation, breast lift surgery, or breast reduction. Additional complications can include bleeding beneath the tissue, infection, fat tissue death, slow wound healing, and changes to the nipple or areola location.
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. Breast implants are not designed to last for an entire lifetime. Health Canada also provides safety information about uncommon conditions linked with certain breast implants, including breast implant-associated anaplastic large cell lymphoma.
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. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated.
Possible Tummy Tuck and Body Lift Complications
Tummy tuck and body lift procedures require long incisions and repositioning of broad tissue areas. Possible complications include fluid buildup, DVT, infection, tissue loss, incision opening, reduced sensation, visible scars, and changes in navel shape or placement. 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. Some of the transferred fat will be absorbed, which can affect volume and symmetry. 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.
Factors That Increase the Risk of Complications
Some health and lifestyle factors can raise the chance of complications. Preoperative preparation may include laboratory testing, medication changes, weight management, stopping nicotine, or obtaining medical clearance.
Factors associated with higher surgical risk include:
- Smoking, vaping, or using nicotine products
- Diabetes with unstable or elevated blood sugar
- 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
- Sleep apnea
- Conditions affecting the immune system
- Poor nutrition or significant anemia
- Earlier surgery or radiation therapy involving the same area
- Medications or supplements that affect bleeding or healing
- Expectations that cannot be achieved or unaddressed psychological concerns affecting consent
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 and Emotional Risks
Cosmetic surgery can affect emotional health as well as physical health. Swelling, bruising, fatigue, and temporary lifestyle restrictions may leave some patients feeling worried, frustrated, or low. 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.
The patient's motivation for considering surgery should be discussed during an appropriate assessment. Possible warning signs include outside pressure, ongoing dissatisfaction despite multiple operations, severe concern about a minor feature, and unrealistic beliefs about total life transformation.
Intense and persistent concern about perceived physical defects may be a sign of body dysmorphic disorder, a recognized mental health condition. 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.
- 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.
- Ask where the procedure will be performed and what safety, emergency, and infection-control systems are available.
- Give the surgical team accurate information about diagnoses, operations, prescriptions, supplements, substances, and allergies.
- Carefully follow all directions related to eating, drinking, preoperative tests, medication adjustments, and nicotine cessation.
- Plan for a trusted adult to take you home and help with daily needs after surgery.
- Review the expected healing schedule before arranging employment, trips, strenuous activity, or important occasions.
- 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
Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. Patients can search the public register of the applicable college of physicians and surgeons to confirm a doctor's licence, registered specialty, and available practice information.
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 training and certification do you have?
- 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?
- What rare but serious risks should I understand?
- Who will provide anesthesia?
- Who should I contact if I experience a complication outside normal clinic hours?
- 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?
Understanding Informed Consent
Informed consent is more than signing a form. It is an ongoing discussion that should give the patient enough information to make a voluntary decision.
A proper consent discussion includes the procedure itself, expected improvement, significant complications, alternative options, recovery requirements, limitations, and the choice to decline treatment. 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. 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.
Symptoms that may require urgent care include:
- Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness
- Unexpected pain, swelling, redness, or heat affecting one leg
- Uncontrolled bleeding or a sudden increase in swelling
- Pain that remains severe despite the prescribed treatment plan
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Mental confusion, severe weakness, or unusual inability to remain alert
- Possible tissue damage shown by abnormal colour, blistering, or low skin temperature
- Loss of sight, intense eye pain, or an abrupt disturbance in vision
- Persistent vomiting that prevents normal hydration
- Any problem your surgeon specifically described as requiring emergency care
Call 911 or seek emergency care when symptoms may be life-threatening. 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.
Cosmetic Surgery Costs and Canadian Health Coverage
Procedures performed only to change appearance are generally not covered by provincial or territorial health insurance. The patient is normally responsible for surgeon fees, anesthetic services, facility charges, implants, compression garments, medication, tests, and associated costs.
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.
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 modern cosmetic surgery 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. This is an important part of responsible care.
How to Make an Informed Cosmetic Surgery Decision
Understanding the risks of cosmetic surgery does not mean assuming that complications will occur. Instead, risk awareness allows patients to decide using reliable facts rather than marketing, online trends, or cost as the only factor.
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.
