What to Know About the Risks of Cosmetic Surgery

Cosmetic surgery can improve the shape, proportion, or appearance of the face and body. A person may also feel more at ease with a long-standing appearance concern after cosmetic surgery. Even so, all operations involve some uncertainty. Understanding the risks of cosmetic surgery is an important 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. 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. During a careful consultation, patients should be able to consider the facts without being rushed. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits. What Are the Risks of Cosmetic Surgery? Any undesirable medical, functional, or cosmetic result connected with an operation may be considered a cosmetic surgery risk. 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. During early recovery, swelling, bruising, tenderness, numbness, tightness, tiredness, and light drainage may be normal. A complication is different. It is a problem that goes beyond the expected recovery process and may require medical treatment. Potential problems associated with plastic surgery include: A hematoma, which is a collection of blood, or other excessive bleeding Incision-site or deep-tissue infection Seroma formation, which involves fluid collecting beneath the tissue Blood clots affecting the legs or lungs Delayed wound healing or wound separation Scars that become prominent, raised, wide, or uneven Nerve injury, numbness, or altered sensation Skin, fat, or tissue loss caused by poor blood supply Reactions to anesthesia, medications, adhesives, or surgical materials Aesthetic concerns such as asymmetry, poor contours, or an unwanted result Changes in function, such as breathing, movement, or sensation A need for further care or corrective surgery Major complications do not happen often, but patients should understand that they remain possible. 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 Some discomfort and physical change are part of normal healing. Patients who understand expected recovery are better able to separate routine symptoms from possible complications. Postoperative Pain and Tenderness Each patient experiences pain differently, and some operations cause more discomfort than others. The surgical site can feel tender, tight, sore, or mildly burning during recovery. Pain should usually become easier to manage as healing continues. Prompt medical advice is needed if pain suddenly worsens, begins spreading, or appears with fever, redness, breathing difficulty, or unexpected swelling. Swelling and Bruising Swelling is caused by inflammation and fluid moving into the treated tissues. 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. Patients undergoing face surgery, breast surgery, liposuction, or body contouring may experience noticeable bruising and swelling. The outcome of surgery should not be assessed before healing has progressed. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different. Numbness and Changes in Sensation Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. Temporary changes such as tingling, numbness, tenderness, or reduced sensation may occur after surgery. Nerve recovery often improves sensation over time, but normal feeling may not return completely. Permanent sensory changes are possible. Short-Term Activity Restrictions Patients may need help with transportation, meals, child care, pet care, household work, and personal tasks. 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. Medical and Surgical Risks 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. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body. Depending on its size and symptoms, a hematoma may be watched or medically drained. A return to the operating room may be necessary in more serious cases. Infection The incision, nearby skin, deeper surgical tissues, or an implant pocket can become infected. Warning signs can include spreading redness, heat, swelling, worsening pain, pus-like fluid, fever, chills, or an unusual odour. An infection can require medication, incision care, removal of fluid, or an additional procedure. An infected breast implant or other medical device may need to be removed. Smoking, uncontrolled diabetes, poor nutrition, and problems with blood circulation can raise the risk of infection or make it harder to treat. Fluid Buildup or Seroma Clear fluid that gathers beneath the skin is known as a seroma. Procedures such as abdominoplasty, body lift surgery, breast surgery, and large-area liposuction may have a greater seroma risk because they create space beneath the tissue. Small seromas may resolve as the body absorbs the fluid. 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 Deep vein thrombosis, known as DVT, develops when a clot forms in one of the body's deep veins, usually in a leg. 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. 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 A surgical wound may take longer than expected to close or may start to open. Healing may be impaired by poor circulation, infection, pressure on the incision, nicotine, some medicines, or underlying health conditions. 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. Tissue Necrosis Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to die. 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. The extent of tissue damage determines which treatment is required. It may involve wound care, removal of damaged tissue, skin grafting, reconstructive surgery, or a delayed revision. Risks Related to Anesthesia Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. 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: Nausea and vomiting Light-headedness, confusion, or extended sleepiness Throat discomfort or headache Unexpected reactions to anesthetic or other medications Fluctuations in blood pressure or disturbances in heartbeat Respiratory difficulty Aspiration of stomach contents into the lungs Dental, lip, or airway damage 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. 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. Scars often appear red, raised, firm, or darker during early healing. 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 and Keloid Scarring A scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. Keloid tissue spreads past the edges of the initial incision. People with a personal or family history of abnormal scarring should tell their surgeon before surgery. 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 The treated skin may develop colour changes, redness, noticeable blood vessels, dimpling, firmness, or textural differences. Some of these changes resolve over time, while others can last permanently. A patient's skin tone and the procedure being performed can influence the likelihood of these changes. The Risk of an Unwanted Cosmetic Result A procedure can be medically and technically successful while still producing a result the patient did not anticipate. Individual anatomy, skin flexibility, age, past procedures, scarring, and natural asymmetry all affect healing. Appearance-related problems may include: Persistent asymmetry Visible dents, bulges, or contour differences 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 Gradual recurrence of skin or tissue laxity Disappointment with an outcome that falls within an acceptable surgical range Visual examples and digital imaging can guide consultation discussions, although no patient can be guaranteed the same outcome. Anatomy and healing responses vary from one person to another. Revision Cosmetic Surgery A corrective operation may be discussed if a complication develops or if the original result could be refined. Revision surgery carries risks of its own. Because scarred tissues may be less flexible and have reduced circulation, revision procedures can be more difficult. 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. Complications by Type of Cosmetic Surgery 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. Because nicotine restricts circulation, its use can greatly increase wound and skin-healing complications. Possible Rhinoplasty Complications Potential rhinoplasty complications include long-lasting swelling, bleeding, infection, unevenness, altered smell, contour problems, a hole in the septum, structural collapse, and nasal breathing difficulty. The final shape may take a year or longer to become clear. Revision rhinoplasty can be more difficult because of scar tissue and changes to the cartilage. 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. Immediate medical evaluation is needed for intense eye pain or a sudden visual disturbance. 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. 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. Patients should not assume that breast implants will remain in place permanently without further care. 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. 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. Possible complications include fluid buildup, DVT, infection, tissue loss, incision opening, reduced sensation, visible scars, and changes in navel shape or placement. Recovery may involve several weeks of limited movement and physical activity. Fat Grafting Risks Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. Some of the transferred fat will be absorbed, which can affect volume and symmetry. Fat grafting may also cause fat necrosis, cyst formation, calcium deposits, infection, oily fluid collections, or unintended injection into circulation. 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. Before proceeding, some patients require tests, adjustments to treatment, weight changes, nicotine cessation, or approval from another medical professional. 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 clotting or bleeding condition, or previous blood clots Obesity, unstable weight, or recent major weight loss or gain Sleep apnea 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 Expectations that cannot be achieved or unaddressed psychological concerns affecting consent 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. Psychological Effects of Cosmetic Surgery The effects of cosmetic surgery may be psychological and emotional, not only physical. During recovery, patients can become anxious or discouraged because they look swollen, feel tired, and cannot resume normal activities. 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. Although surgery can alter appearance, it cannot promise self-confidence, fix relationships, ensure professional success, or resolve wider life difficulties. 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. Intense and persistent concern about perceived physical defects may be a sign of body dysmorphic disorder, a recognized mental health condition. An operation may fail to resolve the deeper psychological distress. A psychological evaluation or professional support may be recommended before surgery when concerns are identified. How to Reduce the Risks of Cosmetic Surgery Risk cannot be removed completely, but careful planning can make cosmetic surgery safer. Choose a properly qualified physician with training and experience relevant to the procedure. Verify the physician's registration and standing through the medical regulatory authority in your province or territory. Find out which facility will be used and whether it has suitable emergency plans, safety standards, and infection prevention measures. Provide a complete medical history, including medications, supplements, nicotine, cannabis, alcohol, allergies, and prior operations. Complete required testing and obey instructions about fasting, medicines, supplements, smoking, vaping, and other nicotine products. 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. Do not compare your healing speed with edited images or another patient's recovery. Do not make an early decision about revision, because the tissues may require many months to heal and stabilize. Choosing a Cosmetic Surgeon in Canada 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. Another useful question is whether the doctor holds plastic surgery certification from 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 plastic surgery nearby environment, and postoperative support. Useful questions for a cosmetic surgery consultation include: What are your surgical qualifications and specialty credentials? How many times have you carried out this operation? Am I a suitable candidate based on my health and anatomy? Which problems do your patients experience most often after this operation? Which uncommon but severe complications need to be considered? 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? What follow-up visits are included? Which additional expenses would I be responsible for if a complication or revision occurs? Informed Consent for Cosmetic Surgery Informed consent is more than signing a form. It should be a continuing conversation that allows the patient to decide freely after receiving adequate information. A proper consent discussion includes the procedure itself, expected improvement, significant complications, alternative options, recovery requirements, limitations, and the choice to decline treatment. The surgeon should also explain risks that may have particular importance because of the patient's occupation, health, daily activities, or individual goals. Patients should have enough time to review consent information without being pressured. When medical language or a possible complication is confusing, the patient should request a clearer explanation. It can be helpful to take notes, bring a trusted person to the consultation, and review written instructions 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. Urgent warning signs may 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 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 An emergency eye symptom such as severe pain, sudden visual change, or vision loss Ongoing vomiting or difficulty drinking without becoming sick Any symptom the surgical team identified as an emergency When a symptom could represent a life-threatening emergency, call 911 or go to an emergency department. 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 Canadian provincial and territorial health plans generally do not pay for operations performed solely for cosmetic reasons. Patients usually pay for the surgeon, anesthesia, operating facility, implants, garments, prescriptions, testing, and other related expenses. Complication-related costs should be discussed before surgery. Coverage may depend on the medical service required, the location where treatment is provided, and the patient's provincial or territorial plan. Travel, accommodation, nursing assistance, missed work, child care, and revision surgery can create additional expenses. 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. Balancing the Benefits and Risks of Cosmetic Surgery A sound decision about cosmetic surgery requires realistic expectations, appropriate health, informed consent, and knowledge of the healing process. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection. Patients should carefully weigh likely improvements against health risks, emotional effects, recovery demands, and financial costs. Think about your ability to obey postoperative instructions, live with scars, take enough time off, and emotionally manage an outcome that is not ideal. 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. Deciding Whether Cosmetic Surgery Is Right for You Understanding the risks of cosmetic surgery does not mean assuming that complications will occur. It means making a thoughtful decision based on accurate information rather than advertising, social media trends, or price alone. Learn about the procedure, review your personal risk factors, confirm the surgeon's qualifications, ask detailed questions, and plan for a full recovery. A complete understanding of the likely improvements, procedure limitations, available options, and associated risks helps patients determine whether cosmetic surgery is appropriate for them.
