Through cosmetic surgery, patients may refine 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. Even so, every surgical procedure involve some uncertainty. Understanding the risks of cosmetic surgery is an important part of deciding whether a procedure is right for you.
A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. Anesthesia, bleeding, infection, healing difficulties, unexpected reactions, and the body's response to an operation can all cause problems. Some problems resolve with simple treatment and do not cause lasting harm. In other cases, a complication can require drugs, hospital care, another operation, or extended monitoring.
Patients in Canada should receive clear information about the expected benefits, material risks, alternatives, recovery requirements, and possible consequences of not having treatment. A careful consultation gives you time to consider this information without pressure. Most cosmetic procedures are optional, which means you can delay or decline surgery when its risks do not justify its likely benefits.
What Are the Risks of Cosmetic Surgery?
Cosmetic surgery risks include any unwanted medical, functional, or aesthetic outcome linked to an operation. 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. Swelling, bruising, soreness, numbness, tightness, fatigue, and mild drainage may be normal during early healing. A complication is different. It is an unexpected problem that exceeds routine healing and can require treatment.
Potential problems associated with plastic surgery include:
- Bleeding or the development of a blood collection known as a hematoma
- An infection in the incision or deeper surgical tissues
- A collection of fluid called a seroma
- Blood clots in the legs or lungs
- An incision that heals poorly, slowly, or begins to open
- 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
- Reactions to anesthesia, medications, adhesives, or surgical materials
- Aesthetic concerns such as asymmetry, poor contours, or an unwanted result
- 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. Possible rare complications include severe infection, major hemorrhage, organ damage, heart problems, stroke, a blood clot in the lungs, permanent impairment, and death.
Common Early Effects During Cosmetic Surgery Recovery
Some discomfort and physical change are part of normal healing. Patients should understand what is expected so they can tell the difference between routine recovery and a warning sign.
Soreness After Cosmetic Surgery
The amount of pain experienced depends on both the procedure and the individual. Patients may notice aching, tightness, burning, or tenderness around the treated area. Discomfort is normally expected to improve gradually during healing. Prompt medical advice is needed if pain suddenly worsens, begins spreading, or appears with fever, redness, breathing difficulty, or unexpected swelling.
Postoperative 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. Small blood vessels can release blood under the skin, creating bruising. Visible bruising and swelling may follow facial surgery, liposuction, breast procedures, or body contouring.
Patients should not judge the final result too early. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
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. Nerve recovery often improves sensation over time, but normal feeling may not return completely. Permanent sensory changes are possible.
Short-Term Activity Restrictions
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. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored.
Surgical and Medical Complications
Bleeding and Hematoma
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. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
A small hematoma may only need monitoring, but a larger one may require drainage. A return to the operating room may be necessary in more serious cases.
Infection After Cosmetic Surgery
Infection may affect the skin, surgical cut, deeper tissue, or the area surrounding an implant. 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. If a breast implant or another implanted device becomes infected, removal may be necessary. Infection risk and treatment difficulty may increase with smoking, poorly controlled diabetes, inadequate nutrition, or reduced circulation.
Fluid Buildup or 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. A persistent seroma can create pressure, interfere with wound healing, and increase the chance of infection.
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.
Risk may increase with long operations, limited movement, previous blood clots, certain medications, nicotine use, obesity, some medical conditions, and combining multiple procedures. Depending on the patient, preventive steps may involve getting up early, using compression equipment or garments, staying hydrated, or taking prescribed blood thinners.
Problems With Incision Healing
Slow healing or separation of the incision can occur after cosmetic surgery. Healing may be impaired by poor circulation, infection, pressure on the incision, nicotine, some medicines, or underlying health conditions.
Incision problems may need wound care, antibiotics, surgical cleaning, or further corrective surgery. Secondary intention healing allows an open wound to fill and close naturally from the bottom upward. This process can take longer and may leave a more visible scar.
Loss of Tissue From Poor Blood Supply
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.
Treatment depends on the amount of tissue affected. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery.
Anesthesia Risks in Cosmetic Surgery
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.
Possible anesthesia-related problems include:
- Feeling sick or vomiting after anesthesia
- Dizziness, confusion, or prolonged drowsiness
- A headache or irritation of the throat
- Allergic or medication reactions
- Changes in blood pressure or heart rhythm
- Problems with breathing
- Stomach contents entering the lungs, known as aspiration
- Injury to the teeth, lips, mouth, or airway
- Major complications involving the heart, lungs, or nervous system
A preoperative health history should include every medication, vitamin, supplement, cannabis product, alcohol or nicotine habit, allergy, previous anesthetic reaction, and relevant diagnosis. Leaving out information can make anesthesia and surgery less safe.
Changes in Scarring, Colour, and Skin Texture
Whenever an incision is made through the skin, a scar will form. Surgeons usually place incisions where they can be hidden within natural folds, hairlines, or clothing, but a scar cannot be erased completely.
During the first stages of healing, scars may look red, thick, firm, elevated, or darker than nearby skin. Scars may require a year or more to flatten, soften, and become less noticeable. How a scar eventually looks is affected by heredity, skin type, wound tension, infection, ultraviolet exposure, aftercare, incision placement, and the operation performed.
Hypertrophic Scars and Keloids
A scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. 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.
Pigment and Texture Irregularities
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.
Cosmetic Outcome Risks and Patient Dissatisfaction
A technically successful operation does not always produce the appearance a patient expected. Healing is affected by anatomy, skin elasticity, age, previous surgery, scar formation, and natural differences between the two sides of the body.
Potential cosmetic outcome concerns include:
- Ongoing asymmetry
- Uneven contours or visible irregularities
- Too little or too much correction
- A result that appears unnatural or excessively tight
- Changes in shape as swelling settles
- An implant that shifts, rotates, or sits incorrectly
- 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. Each patient has different anatomy and heals in a different way.
Revision Cosmetic Surgery
When problems occur or the outcome may benefit from improvement, revision cosmetic surgery can be considered. A second procedure introduces another set of surgical risks. 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. 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
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
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
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.
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. Capsular contracture, rupture, deflation, rippling, displacement, rotation, pain, ongoing imaging, and future surgery may occur with breast implants. Implants are not lifetime devices. Health Canada publishes safety guidance concerning rare illnesses associated with some breast implants, including breast implant-associated anaplastic large cell lymphoma.
Risks of Liposuction
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.
Risks of Abdominoplasty and Body Lift Surgery
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. Seroma, blood clots, infection, necrosis, delayed wound healing, numbness, noticeable scars, and altered belly button position may occur. Recovery may involve several weeks of limited movement and physical activity.
Risks of Fat Transfer
During fat grafting, fat is taken from one body area and placed into a different location. 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. The location where fat is injected, such as the face, breasts, or buttocks, affects the type and seriousness of potential complications.
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.
The likelihood of complications may increase with:
- Exposure to nicotine through smoking, vaping, gum, patches, or other products
- Diabetes with unstable or elevated blood sugar
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A bleeding disorder or history of blood clots
- A high body mass index or significant changes in weight
- A diagnosed or suspected sleep-related breathing disorder
- Immune system disorders
- Poor nutrition or significant anemia
- Earlier surgery or radiation therapy involving the same area
- Medications or supplements that affect bleeding or healing
- Unrealistic expectations or untreated mental health concerns that affect decision-making
Having a risk factor does not always mean surgery is impossible. Instead, the surgeon must assess whether surgery is reasonably safe and determine what preparation is required.
Psychological Effects of Cosmetic Surgery
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. A short period of sadness or emotional difficulty after surgery is sometimes known as 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.
A responsible assessment should explore the patient's reasons for seeking surgery. 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. An operation may fail to resolve the deeper psychological distress. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation.
How to Reduce the Risks of Cosmetic Surgery
Risk cannot be removed completely, but careful planning can make cosmetic surgery safer.
- Work with a properly trained physician whose practice includes the cosmetic operation you are considering.
- Verify the physician's registration and standing through the medical regulatory authority in your province or territory.
- Discuss the surgical location, its safety procedures, infection-control practices, and ability to handle emergencies.
- Disclose your entire health history, including previous surgery, allergies, medications, supplements, alcohol, cannabis, and nicotine use.
- Follow instructions about fasting, medication changes, testing, and stopping nicotine.
- Plan for a trusted adult to take you home and help with daily needs after surgery.
- 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.
- 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.
How to Select a Cosmetic Surgeon in Canada
In Canada, physicians are licensed and regulated by provincial and territorial authorities. Patients cosmetic surgeons near me 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.
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.
Useful questions for a cosmetic surgery consultation include:
- What training and certification do you have?
- How often do you perform this procedure?
- Based on my health, goals, and anatomy, is this procedure suitable for me?
- 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?
- 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 is more than signing a form. It is an ongoing discussion that should give the patient enough information to make a voluntary decision.
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. Risks that are especially relevant to the patient's health, job, lifestyle, or personal priorities should also be discussed.
Patients should have enough time to review consent information without being pressured. Questions should be asked whenever risks, terminology, or instructions are not fully understood. Patients may benefit from writing down information, attending with someone they trust, and reading the documents again at home.
Postoperative Warning Signs
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
- One-sided leg swelling, tenderness, warmth, or discolouration
- Significant bleeding or swelling that expands quickly
- Severe pain that is not controlled by prescribed medication
- A significant fever, shaking chills, expanding redness, or thick discharge
- Disorientation, marked weakness, or excessive drowsiness
- Skin that becomes very pale, dark, blistered, or cold to the touch
- Sudden vision loss, severe eye pain, or major visual changes
- Ongoing vomiting or difficulty drinking without becoming sick
- A symptom listed as urgent in the postoperative instructions
Emergency medical services should be contacted immediately for potentially life-threatening complications. Do not wait for an office to reopen when there is severe breathing trouble, chest pain, loss of consciousness, major bleeding, or another urgent concern.
Cosmetic Surgery Costs and Canadian Health Coverage
When a procedure is intended only to improve appearance, public health insurance in Canada will usually not cover it. Out-of-pocket expenses may include the surgeon, anesthesia provider, operating room, medical devices, recovery clothing, prescriptions, laboratory work, and follow-up items.
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. 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. An inexpensive overseas package may exclude the cost of treating infection, poor healing, DVT, implant problems, and corrective operations.
Balancing the Benefits and Risks of Cosmetic Surgery
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.
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 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. 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.
