What to Know About the Possible Complications of Cosmetic Surgery

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. Even so, all operations involve some uncertainty. A careful decision about cosmetic surgery should include a clear understanding of its possible risks. 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. 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. Risk levels vary according to the procedure, surgical method, treatment area, operation length, anesthesia type, and the patient's general health. It is normal for patients to experience some minor effects after many operations. 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. A complication extends beyond normal recovery and may need medical care. 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 Fluid buildup, known as a seroma Clots that form in a leg vein or travel to the lungs Delayed wound healing or wound separation Noticeable, raised, widened, or uneven scars Nerve injury, numbness, or altered sensation Loss of skin, fat, or other tissue because of reduced circulation Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials Unevenness, contour irregularities, or an unsatisfactory appearance Changes in function, such as breathing, movement, or sensation A need for further care or corrective 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 should understand what is expected so they can tell the difference between routine recovery and a warning sign. Pain and Tenderness Pain levels vary by procedure and patient. Tightness, aching, burning, or tenderness may occur near the surgical area. Pain should usually become easier to manage as healing continues. 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. 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. 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. Altered Sensation and Numbness During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Temporary changes such as tingling, numbness, tenderness, or reduced sensation may occur after surgery. 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 Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. Patients may be temporarily unable to drive, exercise, lift heavy objects, swim, or resume their jobs. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications. Potential Surgical Complications Bleeding or Blood Collection A small amount of bleeding may occur around an incision. When bleeding is more substantial, blood may collect under the skin or in the surgical site and form a hematoma. Possible signs of a hematoma include worsening pain, hard swelling, colour changes, or sudden asymmetry. Some hematomas can be observed, while others must be drained. In certain cases, the patient may need to return to the operating room. Infection After Cosmetic Surgery An infection can develop in the skin, incision, tissue, or around an implant. 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. 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. 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. A larger seroma may require drainage on one or several occasions. Untreated fluid can place pressure on the incision, affect healing, or become infected. 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. Factors that may raise blood clot risk include lengthy surgery, reduced mobility, a history of clots, particular medications, nicotine exposure, obesity, certain illnesses, and multiple procedures performed together. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable. Delayed or Difficult Wound Healing Slow healing or separation of the incision can occur after cosmetic surgery. 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. When a wound is left to close slowly from its deeper layers toward the surface, the process is called healing by secondary intention. Healing in this way often takes more time and can result in a more noticeable scar. Loss of Tissue From Poor Blood Supply Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and die. Operations that move, tighten, or lift broad areas of tissue can carry a risk of necrosis. Smoking, vaping, and other nicotine use can greatly increase risk by narrowing blood vessels and reducing tissue oxygen. 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: Nausea and vomiting Dizziness, mental confusion, or drowsiness that lasts longer than expected Throat discomfort or headache An allergic response or adverse drug reaction Fluctuations in blood pressure or disturbances in heartbeat Respiratory difficulty Aspiration, which occurs when material from the stomach reaches the lungs Injury to the teeth, lips, mouth, or airway Severe cardiac, respiratory, or neurological problems A preoperative health history should include every medication, vitamin, supplement, cannabis product, alcohol or nicotine habit, allergy, previous anesthetic reaction, and relevant diagnosis. The safety of the operation can be reduced when important health information is omitted. Changes in Scarring, Colour, and Skin Texture 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. 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. 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. A keloid grows beyond the borders of the 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. 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 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. 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 procedure can be medically and technically successful while still producing a result the patient did not anticipate. Healing is affected by anatomy, skin elasticity, age, previous surgery, scar formation, and natural differences between the two sides of the body. Appearance-related problems may include: Persistent asymmetry Uneven contours or visible irregularities Under-correction or over-correction An artificial-looking or over-tightened outcome A changing contour as postoperative swelling decreases 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. Each patient has different anatomy and heals in a different way. Revision Cosmetic Surgery Revision surgery may be considered when a complication occurs or when the result can be improved. A second procedure introduces another set of surgical risks. A second operation may be technically harder because previous surgery can leave scar tissue, stiffness, and diminished blood flow. Patients should ask what the clinic's revision policy covers. Additional costs for the surgeon, operating room, anesthetic, implants, medicine, transportation, accommodation, and missed employment may fall outside the initial price. Risks Associated With Specific Cosmetic Procedures General surgical risks apply to many operations, but each procedure also has unique concerns. Risks of Facelift and Neck Lift Surgery Facelift and neck lift complications may include hematoma, facial nerve injury, hairline changes, hair loss near incisions, skin loss, contour irregularities, earlobe distortion, numbness, facial weakness, and visible scarring. Smoking, vaping, and other nicotine exposure can significantly raise the chance cosmetic plastic surgery of skin loss and delayed healing. Rhinoplasty Risks 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. 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. Immediate medical evaluation is needed for intense eye pain or a sudden visual disturbance. 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. Patients in Canada can review Health Canada information about uncommon implant-related conditions, such as 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. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated. Risks of Abdominoplasty and Body Lift Surgery Tummy tuck and body lift procedures require long incisions and repositioning of broad tissue areas. Seroma, blood clots, infection, necrosis, delayed wound healing, numbness, noticeable scars, and altered belly button position may occur. Activity and lifting restrictions can remain in place for a number of weeks. 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. 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? 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. 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 or major weight changes A diagnosed or suspected sleep-related breathing disorder Conditions affecting the immune system Nutritional deficiencies or a low red blood cell count Previous radiation or surgery in the treatment area Prescription products, non-prescription medicines, or supplements that alter bleeding and healing Mental health concerns or unrealistic goals that interfere with informed decision-making Having a risk factor does not always mean surgery is impossible. It means the surgeon must decide whether the procedure can be performed safely and whether changes are needed before proceeding. Emotional and Mental Health Considerations An operation performed for appearance can influence a patient's mental and emotional state in addition to the body. Some patients feel anxious, impatient, or discouraged while swollen, bruised, tired, and unable to follow their normal routine. This temporary low mood is sometimes called postoperative blues. More serious dissatisfaction can occur when expectations do not match what surgery can realistically achieve. 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. Concerns may arise when someone is being pressured, remains unhappy after repeated procedures, is intensely focused on a small flaw, or expects surgery to change every part of life. Body dysmorphic disorder is a mental health condition involving intense distress about perceived appearance flaws. 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. Ways to Lower Cosmetic Surgery Risks Risk cannot be removed completely, but careful planning can make cosmetic surgery safer. 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. 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. 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. Understand the recovery timeline before booking work, travel, exercise, or major events. Attend all follow-up appointments and report unusual symptoms promptly. Your recovery should not be compared with social media images, promotional content, or another person's timeline. Do not make an early decision about revision, because the tissues may require many months to heal and stabilize. Finding a Qualified Canadian Cosmetic Surgeon Medical regulation in Canada is handled at the provincial and territorial level. The public directory of the appropriate college of physicians and surgeons can be used to check licensing, specialty registration, and listed practice details. Canadian patients can ask if their surgeon has been 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? Does my medical history and physical anatomy make me an appropriate candidate? What complications are seen most frequently with this procedure in your practice? Which uncommon but severe complications need to be considered? Which medical professional will administer and monitor my 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? What follow-up visits are included? Could I face extra surgeon, facility, anesthesia, medication, or revision fees? What Informed Consent Should Include Signing paperwork alone does not create true informed consent. 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. 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. 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. Warning Signs After Cosmetic Surgery Your surgical team should provide specific instructions about when and how to seek help. Unexpected or worsening symptoms that fall outside the recovery instructions should be reported without delay. Symptoms that may require urgent care include: Chest pain, shortness of breath, coughing blood, or fainting Unexpected pain, swelling, redness, or heat affecting one leg Significant bleeding or swelling that expands quickly Severe pain that is not controlled by prescribed medication High fever, chills, spreading redness, or pus-like drainage 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 symptom the surgical team identified as an emergency 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. Financial Considerations for Cosmetic Surgery in Canada When a procedure is intended only to improve appearance, public health insurance in Canada will usually not cover it. Patients usually pay for the surgeon, anesthesia, operating facility, implants, garments, prescriptions, testing, and other related expenses. Before an operation, patients should ask who pays for treatment if a complication develops. 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. Patients considering medical tourism should think about who will provide follow-up care after returning to Canada. 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 A sound decision about cosmetic surgery requires realistic expectations, appropriate health, informed consent, and knowledge of the healing process. Realistic patients seek meaningful improvement while accepting that no procedure can deliver a flawless result. Before deciding, compare what the operation may achieve with its physical, psychological, practical, and economic consequences. The decision should account for recovery restrictions, permanent scarring, employment absence, and the possibility that the final result may fall short of expectations. When complications are too likely, benefits are small, or expectations cannot be met safely, an experienced surgeon may recommend against operating. A decision not to operate is sometimes the safest and most responsible form of patient care. Making an Informed Decision Being aware of possible complications is not the same as believing they are certain to happen. It means making a thoughtful decision based on accurate information rather than advertising, social media trends, or price alone. A safer decision involves understanding the procedure, identifying individual risk factors, checking the surgeon's qualifications, discussing concerns, and organizing postoperative care. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
