What to Know About the Possible Complications of Cosmetic Surgery

The shape, proportion, or overall appearance of the face and body can be enhanced through cosmetic surgery. It may also help a person feel more comfortable with a feature that has bothered them for years. Cosmetic surgery may offer benefits, but no operation is entirely predictable. A careful decision about cosmetic surgery should include a clear understanding of its possible risks. Although most patients heal without serious problems, no surgeon can guarantee perfection or eliminate every surgical risk. Problems can occur because of anesthesia, bleeding, infection, poor healing, an unexpected reaction, or the way the body responds to surgery. Some complications are temporary and easy to treat. Others may require medication, hospital care, revision surgery, or long-term follow-up. Canadian patients should receive understandable information about benefits, material risks, available alternatives, recovery demands, and the possible effects of choosing no treatment. A careful consultation gives you time to consider this information without pressure. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits. What Are the Risks of Cosmetic Surgery? The risks of cosmetic surgery include unwanted outcomes that affect health, physical function, or appearance. The procedure being performed, technique used, body area treated, duration of surgery, anesthesia method, and patient health all influence risk. Many cosmetic procedures are followed by mild expected side effects. 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. Possible complications of plastic surgery include: Bleeding or the development of a blood collection known as a hematoma Incision-site or deep-tissue infection Fluid buildup, known as a seroma Clots that form in a leg vein or travel to the lungs An incision that heals poorly, slowly, or begins to open Visible scarring that may be thick, widened, raised, or irregular 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 Asymmetry, contour problems, or an unwanted appearance Problems with normal function, including breathing, motion, or sensation The need for additional treatment or revision surgery Major complications do not happen often, but patients should understand that they remain possible. Uncommon but severe risks can include serious infection, substantial bleeding, damage to an organ, cardiac complications, stroke, pulmonary embolism, lasting disability, or death. Common Early Effects During Cosmetic Surgery Recovery A degree of discomfort and physical change is expected while the body heals. Patients should understand what is expected so they can tell the difference between routine recovery and a warning sign. 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. As recovery progresses, pain should generally become less intense and easier to control. Pain that suddenly becomes severe, spreads, or occurs with fever, redness, shortness of breath, or unusual swelling should be reported promptly. Swelling and Bruising Inflammation and the movement of fluid into surgical tissues cause swelling. It may hide the initial surgical result for weeks or months. Small blood vessels can release blood under the skin, creating bruising. 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. Remaining swelling may temporarily affect shape, balance, and the texture of the skin. Numbness and Changes in Sensation Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. Some procedures commonly cause short-term numbness, tingling, increased sensitivity, or a decrease in feeling. Nerve recovery often improves sensation over time, but normal feeling may not return completely. There is a possibility that altered feeling will not fully resolve. Short-Term Activity Restrictions 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. Failing to follow activity restrictions may raise the risk of bleeding, swelling, wound breakdown, and other problems. Potential Surgical Complications Postoperative Bleeding and Hematoma 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. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body. 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 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. 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. Postoperative Seroma Clear fluid that gathers beneath the skin is known as a seroma. Seromas occur more often after operations that leave a broad space under the tissue, including tummy tuck surgery, body lifts, breast procedures, and extensive liposuction. A minor fluid collection can sometimes disappear as the body reabsorbs it. 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. Deep Vein Thrombosis and Pulmonary Embolism 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. Long procedures, inactivity, earlier blood clots, some drugs, nicotine use, excess body weight, health conditions, and combined operations can increase the chance of DVT or pulmonary embolism. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable. 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. Incision problems may need wound care, antibiotics, surgical cleaning, or further corrective surgery. Healing by secondary intention means allowing an open area to close gradually from the inside outward. This process can take longer and may leave a more visible scar. Tissue Necrosis Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to 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. Management of necrosis varies according to the size and depth of the affected area. Possible treatment includes wound management, removal of dead tissue, a skin graft, reconstructive surgery, or revision at a later date. Potential Complications of Anesthesia Depending on the operation, cosmetic surgery can involve local anesthetic, sedating medication, general anesthesia, or multiple methods together. Choosing an anesthesia method requires consideration of the operation, medical background, expected surgical time, and facility. Anesthesia may be associated with the following risks: Nausea and vomiting Dizziness, confusion, or prolonged drowsiness Throat discomfort or headache Allergic or medication reactions Fluctuations in blood pressure or disturbances in heartbeat Problems with breathing Aspiration of stomach contents into the lungs Injury to the teeth, lips, mouth, or airway Serious heart, lung, or neurological complications A preoperative health history should include every medication, vitamin, supplement, cannabis product, alcohol or nicotine habit, allergy, previous anesthetic reaction, and relevant diagnosis. Withholding medical or lifestyle information may increase the risks of anesthesia and surgery. Cosmetic Surgery Scars and Skin Changes A surgical procedure that breaks the skin will always leave some degree of scarring. Incisions are often positioned in natural creases, along hairlines, or beneath clothing, although no scar can be removed entirely. During the first stages of healing, scars may look red, thick, firm, elevated, or darker than nearby skin. Over 12 months or longer, scar tissue can gradually fade and soften. The final appearance depends on genetics, skin type, incision tension, infection, sun exposure, wound care, location, and the type of operation. Hypertrophic Scars and Keloids Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the Cosmetic North wound. Patients should inform their surgeon if they or close family members have developed raised or unusual scars. Possible treatments include silicone products, pressure therapy, copyright injections, laser treatment, or scar revision. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return. Pigment and Texture Irregularities Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin texture. These effects may be temporary or permanent. 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. 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: Unevenness that remains after healing Visible dents, bulges, or contour differences Under-correction or over-correction An unnatural or overly tight appearance Alterations in shape while swelling resolves Movement or poor positioning of an implant Scarring that is prominent or difficult to conceal Recurrence of sagging or tissue laxity over time Disappointment with an outcome that falls within an acceptable surgical range Before-and-after images, photographs, and computer simulations may help explain possibilities, but they do not promise a matching result. Anatomy and healing responses vary from one person to another. Revision Cosmetic Surgery Revision surgery may be considered when a complication occurs or when the result can be improved. However, another operation brings new risks. A second operation may be technically harder because previous surgery can leave scar tissue, stiffness, and diminished blood flow. 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. Possible Facelift and Neck Lift Complications Hematoma, facial nerve injury, hairline alteration, hair loss around incisions, skin necrosis, contour problems, earlobe changes, loss of feeling, facial weakness, and visible scarring are among the risks of facelift and neck lift surgery. 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. A rhinoplasty result may not fully settle for 12 months or more. Scar formation and altered cartilage can make secondary rhinoplasty more complex. Eyelid Surgery Risks 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. Immediate medical evaluation is needed for intense eye pain or a sudden visual disturbance. Breast Surgery Risks Breast augmentation, breast lift, and breast reduction may affect nipple sensation, breast symmetry, scar appearance, and the ability to breastfeed. Other risks include hematoma, infection, fat necrosis, delayed healing, and changes in nipple or areola position. Breast implants bring added long-term considerations. These include capsular contracture, implant rupture, deflation, rippling, movement, rotation, pain, and the need for future monitoring or surgery. 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 Liposuction complications may include contour irregularities, dents, rippling, loose skin, fluid imbalance, numbness, seroma, infection, internal injury, fat embolism, and lidocaine toxicity when local anesthetic is used. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated. Tummy Tuck and Body Lift Risks 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. Fat Grafting Risks Fat transfer involves removing fat from one area and injecting it into another. Some of the transferred fat will be absorbed, which can affect volume and symmetry. 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. Factors That Increase the Risk of Complications Some health and lifestyle factors can raise the chance of complications. A patient may need medical testing, treatment changes, weight management, nicotine cessation, or clearance from another health professional before surgery. Factors associated with higher surgical risk include: Exposure to nicotine through smoking, vaping, gum, patches, or other products Diabetes with unstable or elevated blood sugar Heart, lung, kidney, liver, or blood vessel disease A clotting or bleeding condition, or previous blood clots A high body mass index or significant changes in weight Sleep apnea Immune system disorders Nutritional deficiencies or a low red blood cell count Scar tissue or circulation changes from prior operations or radiation Drugs, vitamins, or supplements that interfere with clotting or tissue repair Mental health concerns or unrealistic goals that interfere with informed decision-making The presence of one or more risk factors does not automatically prevent cosmetic surgery. The surgeon needs to evaluate the level of risk and decide whether health or lifestyle changes are necessary before treatment. 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. 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. A cosmetic procedure can modify the body, but it does not guarantee emotional confidence, relationship improvement, career advancement, or solutions to unrelated personal concerns. A careful cosmetic surgery consultation should examine why the patient wants the procedure. 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 Cosmetic surgery always carries some risk, yet careful planning can reduce the likelihood of complications. Select a qualified doctor who has appropriate education and substantial experience performing the procedure. Confirm through your province or territory's college of physicians and surgeons that the doctor is licensed and in good standing. 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. Complete required testing and obey instructions about fasting, medicines, supplements, smoking, vaping, and other nicotine products. When needed, organize transportation and early postoperative support from a responsible adult. Do not schedule travel, work duties, exercise, or major events until you understand how long recovery may take. Attend all follow-up appointments and report unusual symptoms promptly. Avoid judging your recovery against filtered photographs or the healing experience of someone else. 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 In Canada, physicians are licensed and regulated by provincial and territorial authorities. Patients may verify a physician's licence and registered specialty through the online register maintained by their provincial or territorial regulator. Canadian patients can ask if their surgeon has been certified in plastic surgery by the Royal College of Physicians and Surgeons of Canada. While certification matters, patients should also assess procedure-specific experience, communication, the quality of the facility, aftercare, and the surgeon's approach to complications. Questions to ask during a cosmetic surgery consultation include: What professional education and certifications have you completed? How frequently is this specific procedure performed in your practice? Am I a suitable candidate based on my health and anatomy? Which problems do your patients experience most often after this operation? What low-frequency, high-impact risks should I know about? Who is responsible for anesthesia care during the operation? 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? What costs could arise if I need treatment or revision surgery? What Informed Consent Should Include Informed consent involves more than placing a signature on a document. The process requires clear communication so that the patient can make a knowledgeable and voluntary choice. Patients should be informed about how the operation works, its likely benefits, material risks, alternatives, healing process, limits, and the possible consequences of no surgery. Risks that are especially relevant to the patient's health, job, lifestyle, or personal priorities should also be discussed. A patient should never feel rushed to sign. Questions should be asked whenever risks, terminology, or instructions are not fully understood. Taking notes, involving a support person, and reviewing written material outside the clinic can support an informed decision. Warning Signs After Cosmetic Surgery The surgeon's office should explain which symptoms require attention and copyright the appropriate provider. Unexpected or worsening symptoms that fall outside the recovery instructions should be reported without delay. Potential emergency signs after cosmetic surgery include: Breathing problems, chest discomfort, bloody coughing, or fainting Sudden swelling, pain, redness, or warmth in 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 Confusion, extreme weakness, or difficulty staying awake Skin that becomes very pale, dark, blistered, or cold to the touch An emergency eye symptom such as severe pain, sudden visual change, or vision loss Persistent vomiting that prevents normal hydration 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 When a procedure is intended only to improve appearance, public health insurance in Canada will usually not cover it. The patient is normally responsible for surgeon fees, anesthetic services, facility charges, implants, compression garments, medication, tests, and associated costs. Before an operation, patients should ask who pays for treatment if a complication develops. Coverage may depend on the medical service required, the location where treatment is provided, and the patient's provincial or territorial plan. Patients should budget for possible travel, lodging, caregiving, time away from employment, child care, and future revision surgery. Patients considering medical tourism should think about who will provide follow-up care after returning to Canada. An inexpensive overseas package may exclude the cost of treating infection, poor healing, DVT, implant problems, and corrective operations. Weighing Cosmetic Surgery Benefits Against Risks 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. 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. Making an Informed Decision Learning about cosmetic surgery risks does not mean expecting that something will go wrong. The goal is to make a careful choice based on medical information, not promotional claims, social media influence, or the lowest price. Before surgery, research the operation, assess your health risks, verify medical credentials, ask thorough questions, and prepare for the complete healing period. A complete understanding of the likely improvements, procedure limitations, available options, and associated risks helps patients determine whether cosmetic surgery is appropriate for them.
