The shape, proportion, or overall appearance of the face and body can be improved through cosmetic surgery. For some people, it can also increase comfort with a physical feature that has caused distress for years. However, every operation involves some degree of 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. Some problems resolve with simple treatment and do not cause lasting harm. More serious problems may call for medication, hospital treatment, revision surgery, or ongoing medical 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 Risks Can Cosmetic Surgery Involve?
Cosmetic surgery risks include any unwanted medical, functional, or aesthetic outcome linked to an operation. 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.
Minor side effects are expected after many procedures. Swelling, bruising, soreness, numbness, tightness, fatigue, and mild drainage may be normal during early healing. A complication is different. A complication extends beyond normal recovery and may need medical care.
Plastic surgery complications may include the following:
- A hematoma, which is a collection of blood, or other excessive bleeding
- Incision-site or deep-tissue infection
- A collection of fluid called a seroma
- Blood clots affecting the legs or lungs
- An incision that heals poorly, slowly, or begins to open
- Noticeable, raised, widened, or uneven scars
- Nerve-related problems, including numbness or unusual sensation
- Tissue damage or loss resulting from inadequate blood flow
- Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products
- Unevenness, contour irregularities, or an unsatisfactory appearance
- Functional changes affecting breathing, movement, or feeling
- Additional medical treatment or a revision operation
Although serious complications are rare, they must still be reviewed before surgery. 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
A degree of discomfort and physical change is expected while the body heals. Patients who understand expected recovery are better able to separate routine symptoms from possible complications.
Postoperative Pain and Tenderness
The amount of pain experienced depends on both the procedure and the individual. Tightness, aching, burning, or tenderness may occur near the surgical area. As recovery progresses, pain should generally become less intense and easier to control. Patients should quickly report severe or spreading pain, especially when it is accompanied by fever, redness, shortness of breath, or unusual swelling.
Postoperative Swelling and Bruising
Swelling develops when inflammation allows fluid to collect in and around the treated area. 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.
Patients are advised to avoid making early judgments about their final appearance. Residual swelling can change shape, symmetry, and skin texture during recovery.
Numbness and Changes in Sensation
During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Some procedures commonly cause short-term numbness, tingling, increased sensitivity, or a decrease in feeling. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. In some cases, changes in sensation may be permanent.
Temporary Limits on Activity
During early recovery, patients may require support with transportation, meals, family duties, pets, household chores, and self-care. 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.
Potential Surgical Complications
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. Possible signs of a hematoma include worsening pain, hard swelling, colour changes, or sudden asymmetry.
A small hematoma may only need monitoring, but a larger one may require drainage. Some hematomas require another operation to control the bleeding and remove collected blood.
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.
Treatment may involve antibiotics, wound care, drainage, or another operation. 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.
Seroma
A seroma is a pocket of clear fluid that collects under the skin. It is more common after procedures that create a large space beneath the tissue, such as tummy tuck surgery, body lift surgery, breast surgery, or extensive liposuction.
Small seromas may resolve as the body absorbs the fluid. Larger ones may need to be drained, sometimes more than once. Untreated fluid can place pressure on the incision, affect healing, or become infected.
Blood Clot Complications
A blood clot that forms in a deep vein, commonly within the leg, is called deep vein thrombosis, or DVT. A pulmonary embolism can occur if a piece of the clot breaks away and reaches the lungs. This complication can be life-threatening and must be treated urgently.
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.
Poor Wound 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. 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. Nicotine exposure is an important avoidable risk because it constricts blood vessels and limits oxygen reaching the tissues.
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.
Anesthesia Risks in Cosmetic Surgery
Local anesthesia, sedation, general anesthesia, or a combination may be used during cosmetic surgery. The most suitable anesthesia plan is based on the type of surgery, patient health history, procedure duration, and location where surgery takes place.
Potential complications connected with anesthesia include:
- Feeling sick or vomiting after anesthesia
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- A headache or irritation of the throat
- An allergic response or adverse drug reaction
- Abnormal blood pressure or irregular heart rhythm
- Problems with breathing
- Stomach contents entering the lungs, known as aspiration
- Damage to teeth, lips, or the airway
- Severe cardiac, respiratory, or neurological problems
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.
Scarring and Changes to the Skin
A surgical procedure that breaks the skin will always leave some degree of scarring. A surgeon may try to conceal incisions in folds, hair-bearing areas, or covered locations, but complete scar elimination is not possible.
Early scars can be firm, raised, reddish, or more deeply coloured before they mature. Scars may require a year or more to flatten, soften, and become less noticeable. The final appearance depends on genetics, skin type, incision tension, infection, sun exposure, wound care, location, and the type of operation.
Raised Scars and Keloid Formation
Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. Keloid tissue spreads past the edges of the initial incision. 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. Although treatment can make a scar less noticeable, recurrence of abnormal tissue remains possible.
Skin Colour and Texture Changes
Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin texture. Some of these changes resolve over time, while others can last permanently. The risk can differ by skin tone and by the type of procedure performed.
The Risk of an Unwanted Cosmetic Result
A technically successful operation does not always produce the appearance a patient expected. Individual anatomy, skin flexibility, age, past procedures, scarring, and natural asymmetry all affect healing.
Potential cosmetic outcome concerns include:
- Unevenness that remains after healing
- Uneven contours or visible irregularities
- Under-correction or over-correction
- An artificial-looking or over-tightened outcome
- Changes in shape as swelling settles
- Implant position problems
- Scarring that is prominent or difficult to conceal
- Gradual recurrence of skin or tissue laxity
- Dissatisfaction despite an acceptable medical result
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
A corrective operation may be discussed if a complication develops or if the original result could be refined. A second procedure introduces another set of surgical risks. Scar tissue can make the procedure more complex, and the tissues may have less blood supply or flexibility than they did before the first surgery.
Before proceeding, patients should understand exactly what is included in the surgeon's or clinic's revision policy. Surgeon fees, facility costs, anesthesia, implants, medications, travel, and time away from work may not all be included in the original price.
Risks Associated With Specific Cosmetic Procedures
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. Because nicotine restricts circulation, its use can greatly increase wound and skin-healing complications.
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
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
Breast augmentation, breast lift, and breast reduction may affect nipple sensation, breast symmetry, scar appearance, and the ability to breastfeed. Additional complications can include bleeding beneath the tissue, infection, fat tissue death, slow wound healing, and changes to the nipple or areola location.
Patients with breast implants face additional concerns that can develop over time. Capsular contracture, rupture, deflation, rippling, displacement, rotation, pain, ongoing imaging, and future surgery may occur with breast implants. Breast implants are not designed to last for an entire lifetime. Health Canada publishes safety guidance concerning rare illnesses associated with some breast implants, including breast implant-associated anaplastic large cell lymphoma.
Possible Liposuction Complications
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. 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
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. 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. Because a portion of the injected fat may not survive, the final fullness and balance can change. Additional complications include dead fat tissue, cysts, calcification, infection, oil cysts, and fat entering 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
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.
Risk factors may include:
- Cigarette smoking, vaping, or any form of nicotine use
- Diabetes with unstable or elevated blood sugar
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A bleeding disorder or history of blood clots
- Obesity, unstable weight, or recent major weight loss or gain
- A diagnosed or suspected sleep-related breathing disorder
- Conditions affecting the immune system
- Inadequate nutrition or serious 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. The surgeon needs to evaluate the level of risk and decide whether health or lifestyle changes are necessary before treatment.
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. This temporary low mood is sometimes called postoperative blues.
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.
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.
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. 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.
- 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.
- Arrange a responsible adult to drive you home and assist during early recovery when required.
- Do not schedule travel, work duties, exercise, or major events until you understand how long recovery may take.
- Go to every scheduled postoperative visit and quickly contact the surgical team about unexpected symptoms.
- Your recovery should not be compared with social media images, promotional content, or another person's timeline.
- 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. 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.
During the consultation, patients may wish to ask:
- What professional education and certifications have you completed?
- How often do you perform this procedure?
- Does my medical history and physical anatomy make me an appropriate candidate?
- What complications are seen most frequently with this procedure in your practice?
- What rare but serious risks should I understand?
- Who will provide anesthesia?
- How can I obtain care if a problem develops at night or on a weekend?
- What emergency plan is in place if I need urgent medical treatment?
- What follow-up visits are included?
- What costs could arise if I need treatment or revision surgery?
Understanding Informed Consent
Informed consent is more than signing a form. The process requires clear communication so that the patient can make a knowledgeable and voluntary choice.
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.
A patient should never feel rushed to sign. When medical language or a possible complication is confusing, the patient should request a clearer explanation. Taking notes, involving a support person, and reviewing written material outside elective cosmetic surgery the clinic can support an informed decision.
When to Seek Help After Cosmetic Surgery
Your surgical team should provide specific instructions about when and how to seek help. The surgical team should be contacted quickly if symptoms become worse, appear unusual, or do not match the expected healing process.
Symptoms that may require urgent care 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
- Intense pain that does not improve after taking the recommended medicine
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Disorientation, marked weakness, or excessive drowsiness
- Possible tissue damage shown by abnormal colour, blistering, or low skin temperature
- Sudden vision loss, severe eye pain, or major visual changes
- Ongoing vomiting or difficulty drinking without becoming sick
- Any problem your surgeon specifically described as requiring emergency care
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 Considerations for Cosmetic Surgery in Canada
Procedures performed only to change appearance are generally not covered by provincial or territorial health insurance. Patients usually pay for the surgeon, anesthesia, operating facility, implants, garments, prescriptions, testing, and other related expenses.
The financial responsibility for postoperative problems should be clarified in advance. Whether care is publicly covered can depend on the treatment needed, where it is delivered, and the rules of the patient's province or territory. Patients should budget for possible travel, lodging, caregiving, time away from employment, child care, and future revision surgery.
Medical tourists need to determine which Canadian provider, if any, will manage recovery and complications after their return. Lower upfront fees may become more expensive if postoperative infection, wound breakdown, clotting, implant complications, or revision treatment is required.
Weighing Cosmetic Surgery Benefits Against Risks
Patients should consider surgery only when their goals are achievable, their health is suitable, and they understand the risks and recovery. A suitable patient recognizes that improvement is possible, but perfection is not.
Before deciding, compare what the operation may achieve with its physical, psychological, practical, and economic consequences. 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.
Making an Informed Decision
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.
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.
