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. For some people, it can also increase comfort with a physical feature that has caused distress 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 problems resolve with simple treatment and do not cause lasting harm. 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? Any undesirable medical, functional, or cosmetic result connected with an operation may be considered a cosmetic surgery risk. 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. Potential problems associated with plastic surgery include: A hematoma, which is a collection of blood, or other excessive bleeding An infection in the incision or deeper surgical tissues Seroma formation, which involves fluid collecting beneath the tissue 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 injury, numbness, or altered sensation Tissue damage or loss resulting from inadequate blood flow Reactions to anesthesia, medications, adhesives, or surgical materials Asymmetry, contour problems, or an unwanted appearance Functional changes affecting breathing, movement, or feeling The need for additional treatment or revision surgery Serious complications are uncommon, but they are still important to discuss. 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 Some discomfort and physical change are part of normal healing. Knowing what normal healing looks like helps patients recognize when a symptom may be 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. 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. Postoperative 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. Bruises form when tiny blood vessels are damaged and blood collects beneath the skin. Patients undergoing face surgery, breast surgery, liposuction, or body contouring may experience noticeable bruising and swelling. The outcome of surgery should not be assessed before healing has progressed. Residual swelling can change shape, symmetry, and skin texture during recovery. Altered Sensation and Numbness 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. Permanent sensory changes are possible. Temporary Limits on Activity Patients may need help with transportation, meals, child care, pet care, household work, and personal tasks. Patients may be temporarily unable to drive, exercise, lift heavy objects, swim, or resume their jobs. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored. Medical and Surgical Risks Bleeding or Blood Collection A limited amount of bleeding around the incision may be expected. 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. Some hematomas require another operation to control the bleeding and remove collected blood. Surgical Infection 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. An infection can require medication, incision care, removal of fluid, or an additional procedure. Removal can be required when infection develops around a breast implant or surgical device. Smoking, uncontrolled diabetes, poor nutrition, and problems with blood circulation can raise the risk of infection or make it harder to treat. 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. Repeated drainage may be necessary when a significant seroma develops. A persistent seroma can create pressure, interfere with wound healing, and increase the chance of infection. 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. If part of the clot travels to the lungs, it can cause a pulmonary embolism. A pulmonary embolism requires emergency medical care. 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. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate. 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. 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. The recovery period may be extended, and the final scar may be more prominent. Skin or 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. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery. Risks Related to Anesthesia 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. Anesthesia may be associated with the following risks: Postoperative nausea or vomiting Dizziness, mental confusion, or drowsiness that lasts longer than expected Throat discomfort or headache An allergic response or adverse drug reaction Abnormal blood pressure or irregular heart rhythm Problems with breathing Stomach contents entering the lungs, known as aspiration Damage to teeth, lips, or the airway Serious heart, lung, or neurological complications Patients must provide complete information about prescriptions, non-prescription drugs, vitamins, supplements, cannabis, alcohol, nicotine, allergies, earlier anesthesia problems, and medical conditions before surgery. Leaving out information can make anesthesia and surgery less safe. Scarring and Changes to the Skin 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. Early scars can be firm, raised, reddish, or more deeply coloured before they mature. Over 12 months or longer, scar tissue can gradually fade and soften. How a scar eventually looks is affected by heredity, skin type, wound tension, infection, ultraviolet exposure, aftercare, incision placement, and the operation performed. 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. 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. Pigment and Texture Irregularities Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven 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. Cosmetic Outcome Risks and Patient Dissatisfaction A procedure can be medically and technically successful while still producing a result the patient did not anticipate. The body's response is shaped by age, anatomy, skin quality, earlier surgery, scar development, and normal side-to-side differences. Possible aesthetic concerns include: Unevenness that remains after healing Uneven contours or visible irregularities Too little or too much correction An artificial-looking or over-tightened outcome A changing contour as postoperative swelling decreases An implant that shifts, rotates, or sits incorrectly Scarring that is prominent or difficult to conceal Recurrence of sagging or tissue laxity over time Dissatisfaction despite an acceptable medical result Photos, digital simulations, and before-and-after galleries can support discussion, but they cannot guarantee an identical outcome. Each patient has different anatomy and heals in a different way. The Possibility of Revision 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. Because scarred tissues may be less flexible and have reduced circulation, revision procedures can be more difficult. 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. 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. Nicotine use can greatly increase the risk of skin-healing problems. 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. Revision rhinoplasty can be more difficult because of scar tissue and changes to the cartilage. Eyelid Surgery Risks After blepharoplasty, patients may develop dry eyes, irritation, blurred vision, trouble shutting the eyelids, lid malposition, asymmetry, scarring, orbital bleeding, or changes in eyesight. 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. Other risks include hematoma, infection, fat necrosis, delayed healing, and changes in nipple or areola position. Implant-based breast surgery involves long-term risks beyond the normal surgical recovery period. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. Implants are not lifetime devices. 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 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 Tummy tuck and body lift procedures require long incisions and repositioning of broad tissue areas. 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 During fat grafting, fat is taken from one body area and placed into a different location. Because a portion of the injected fat may not survive, the final fullness and balance can change. Other risks include fat necrosis, cysts, calcification, infection, oil cysts, and accidental injection into a blood vessel. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area. Factors That Increase the Risk of Complications 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. Risk factors may include: Smoking, vaping, or using nicotine 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 Obesity or major weight changes 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 Prescription products, non-prescription medicines, or supplements that alter bleeding and healing Mental health concerns or unrealistic goals that interfere with informed decision-making A higher-risk medical history does not necessarily make an operation unsuitable. The surgeon needs to evaluate the level of risk and decide whether health or lifestyle changes are necessary before treatment. Emotional and Mental Health Considerations Cosmetic surgery can affect emotional health as well as physical health. 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. A responsible assessment should explore the patient's reasons for seeking surgery. 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. Intense and persistent concern about perceived physical defects may be a sign of body dysmorphic disorder, a recognized mental health condition. Changing the physical feature does not necessarily treat the underlying mental health condition. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation. Ways to Lower Cosmetic Surgery Risks 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. 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. Carefully follow all directions related to eating, drinking, preoperative tests, medication adjustments, and nicotine cessation. 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. 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. Do not make an early decision about revision, because the tissues may require many months to heal and stabilize. How to Select a Cosmetic Surgeon in Canada Medical regulation in Canada is handled at the provincial and territorial level. 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. 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. Questions to ask during a cosmetic surgery consultation include: What training and certification do you have? How many times have you carried out this operation? Am I a suitable candidate based on my health and anatomy? What complications are seen most frequently with this procedure in your practice? Which uncommon but severe complications need to be considered? Who is responsible for anesthesia care during the operation? How can I obtain care if a problem develops at night or on a weekend? What emergency plan is in place if I need urgent medical treatment? Which follow-up visits and services are included in the fee? Which additional expenses would I be responsible for if a complication or revision occurs? Understanding Informed Consent 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. 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. No one should be pushed into signing a surgical consent form quickly. Questions should be asked whenever risks, terminology, or instructions are not fully understood. It can be helpful to take notes, bring a trusted person to the consultation, and review written instructions at home. Warning Signs After Cosmetic Surgery Your surgical team should provide specific instructions about when and how to seek help. The surgical team should be contacted quickly if symptoms become worse, appear unusual, or do not match the expected healing process. Potential emergency signs after cosmetic surgery include: Breathing problems, chest discomfort, bloody coughing, or fainting Sudden swelling, pain, redness, or warmth in one leg Uncontrolled bleeding or a sudden increase in swelling Intense pain that does not improve after taking the recommended medicine A significant fever, shaking chills, expanding redness, or thick discharge Mental confusion, severe weakness, or unusual inability to remain alert Possible tissue damage shown by abnormal colour, blistering, or low skin temperature Loss of sight, intense eye pain, or an abrupt disturbance in vision Repeated vomiting or an inability to keep fluids down Any problem your surgeon specifically described as requiring emergency care 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 Canadian provincial and territorial health plans generally do not pay for operations performed solely for cosmetic reasons. 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. 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. 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. Realistic patients seek meaningful improvement while accepting that no procedure can deliver a flawless result. Take time to compare the expected benefit with the medical, cosmetic plastic surgery nearby emotional, practical, and financial risks. Think about your ability to obey postoperative instructions, live with scars, take enough time off, and emotionally manage an outcome that is not ideal. When complications are too likely, benefits are small, or expectations cannot be met safely, an experienced surgeon may recommend against operating. Recommending against surgery can be a sign of careful and ethical medical practice. How to Make an Informed Cosmetic Surgery Decision Learning about cosmetic surgery risks does not mean expecting that something will go wrong. Instead, risk awareness allows patients to decide using reliable facts rather than marketing, online trends, or cost as the only factor. Learn about the procedure, review your personal risk factors, confirm the surgeon's qualifications, ask detailed questions, and plan for a full recovery. When the benefits, limits, alternatives, and possible complications are understood, patients are better prepared to decide whether cosmetic surgery fits their needs.
