What to Know About the Possible Complications of Cosmetic Surgery

Through cosmetic surgery, patients may change the shape, proportions, or appearance of their face or body. A person may also feel more at ease with a long-standing appearance concern after cosmetic surgery. However, every operation involves uncertainty. Before deciding whether a procedure is suitable, it is essential to understand the risks of cosmetic surgery. 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. Others may require medication, hospital care, revision surgery, or long-term follow-up. In Canada, patients should be clearly informed about expected benefits, important risks, treatment alternatives, recovery needs, and what may happen if they decline surgery. A thorough consultation should provide enough time to review the information and make a decision without pressure. Most cosmetic procedures are optional, which means you can delay or decline surgery when its risks do not justify its likely benefits. Understanding 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. It is normal for patients to experience some minor effects after many operations. Swelling, bruising, soreness, numbness, tightness, fatigue, and mild drainage may be normal during early healing. A complication is different. It is an unexpected problem that exceeds routine healing and can require treatment. Potential problems associated with plastic surgery include: Bleeding or the development of a blood collection known as a hematoma Infection at the incision or within deeper tissue Seroma formation, which involves fluid collecting beneath the tissue Blood clots affecting the legs or lungs An incision that heals poorly, slowly, or begins to open Scars that become prominent, raised, wide, or uneven Nerve-related problems, including numbness or unusual sensation Tissue damage or loss resulting from inadequate blood flow Reactions to anesthesia, medications, adhesives, or surgical materials Unevenness, contour irregularities, or an unsatisfactory appearance Problems with normal function, including breathing, motion, or sensation A need for further care or corrective surgery Although serious complications are rare, they must still be reviewed before surgery. Rare risks may include severe infection, major blood loss, organ injury, heart problems, stroke, pulmonary embolism, permanent disability, or death. Common Early Effects During Cosmetic Surgery Recovery A degree of discomfort and physical change is expected while the body heals. Patients who understand expected recovery are better able to separate routine symptoms from possible complications. Postoperative Pain and Tenderness The amount of pain experienced depends on both the procedure and the individual. Patients may notice aching, tightness, burning, or tenderness around the treated area. Discomfort is normally expected to improve gradually during healing. Patients should quickly report severe or spreading pain, especially when it is accompanied by fever, redness, shortness of breath, or unusual swelling. Postoperative Swelling and Bruising Swelling is caused by inflammation and fluid moving into the treated tissues. 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 should not judge the final result too early. Residual swelling can change shape, symmetry, and skin texture during recovery. Changes in Feeling After Surgery 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. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. Permanent sensory changes are possible. Activity Limitations During Recovery 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. Medical and Surgical Risks Postoperative Bleeding and Hematoma A limited amount of bleeding around the incision may be expected. Heavier bleeding may create a hematoma, a pocket of blood beneath the skin or within the treated area. Possible signs of a hematoma include worsening pain, hard swelling, colour changes, or sudden asymmetry. A small hematoma may only need monitoring, but a larger one may require drainage. A return to the operating room may be necessary in more serious cases. Infection 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. 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. Patients who smoke or have uncontrolled diabetes, nutritional problems, or poor blood flow may face a higher infection risk and slower recovery. Fluid Buildup or Seroma A seroma is a pocket of clear fluid that collects under the skin. 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. A minor fluid collection can sometimes disappear as the body reabsorbs it. A larger seroma may require drainage on one or several occasions. Untreated fluid can place pressure on the incision, affect healing, or become infected. 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. When part of a deep vein clot moves into the lungs, it may block blood flow and cause a pulmonary embolism. This complication can be life-threatening and must be treated urgently. Risk may increase with long operations, limited movement, previous blood clots, certain medications, nicotine use, obesity, some medical conditions, and combining multiple procedures. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable. Delayed or Difficult Wound Healing An incision may heal slowly or begin to separate. Reduced blood supply, infection, tension on the wound, nicotine exposure, certain medications, and medical conditions can interfere with healing. Wound problems may require dressings, antibiotics, removal of damaged tissue, or additional 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. Tissue Necrosis Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to 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. 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. Choosing an anesthesia method requires consideration of the operation, medical background, expected surgical time, and facility. Potential complications connected with anesthesia include: Feeling sick or vomiting after anesthesia Dizziness, confusion, or prolonged drowsiness A headache or irritation of the throat Unexpected reactions to anesthetic or other medications Abnormal blood pressure or irregular heart rhythm Respiratory difficulty Aspiration, which occurs when material from the stomach reaches the lungs Damage to teeth, lips, or the airway Major complications involving the heart, lungs, or nervous system A preoperative health history should include every medication, vitamin, supplement, cannabis product, alcohol or nicotine habit, allergy, previous anesthetic reaction, and relevant diagnosis. Withholding medical or lifestyle information may increase the risks of anesthesia and surgery. Cosmetic Surgery Scars and Skin Changes 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. Scars may require a year or more to flatten, soften, and become less noticeable. The final appearance depends on genetics, skin type, incision tension, infection, sun exposure, wound care, location, and the type of operation. 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. Patients should inform their surgeon if they or close family members have developed raised or unusual scars. Treatment options can include silicone sheets or gels, pressure treatment, corticocopyright injections, laser therapy, and scar revision. Scar treatment may improve texture and appearance, but it cannot ensure that a hypertrophic scar or keloid will never come back. Pigment and Texture Irregularities Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin texture. These effects may be temporary or permanent. A patient's skin tone and the procedure being performed can influence the likelihood of these changes. Aesthetic Risks and Unsatisfactory Results 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. Appearance-related problems may include: Unevenness that remains after healing Irregular or uneven body contours Under-correction or over-correction A result that appears unnatural or excessively tight Changes in shape as swelling settles Movement or poor positioning of an implant Visible or poorly placed scars Recurrence of sagging or tissue laxity over time Patient dissatisfaction even when the result is medically acceptable 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. The Possibility of Revision 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. Patients should ask what the clinic's revision policy covers. 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 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. Because nicotine restricts circulation, its use can greatly increase wound and skin-healing complications. Rhinoplasty Risks 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. Blepharoplasty 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 Breast augmentation, breast lift, and breast reduction may affect nipple sensation, breast symmetry, scar appearance, and the ability to breastfeed. Additional complications can include bleeding beneath the tissue, infection, fat tissue death, slow wound healing, and changes to the nipple or areola location. Patients with breast implants face additional concerns that can develop over time. 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. Health Canada publishes safety guidance concerning rare illnesses associated with some breast implants, including breast implant-associated anaplastic large cell lymphoma. Liposuction Risks Liposuction may lead to dents, surface irregularities, skin looseness, fluid problems, numbness, fluid collection, infection, organ injury, fat embolism, or lidocaine toxicity when local anesthesia is involved. Removing larger volumes of fat or treating several body areas may increase medical stress and recovery demands. Possible Tummy Tuck and Body Lift Complications Tummy tuck and body lift procedures require long incisions and repositioning of broad tissue areas. Risks include seroma, blood clots, infection, skin loss, wound separation, numbness, prominent scarring, and changes to the position or shape of the belly button. Recovery may involve several weeks of limited movement and physical activity. Possible Fat Grafting Complications Fat transfer involves removing fat from one area and injecting it into another. The body naturally absorbs some transferred fat, potentially reducing volume or creating asymmetry. Other risks include fat necrosis, cysts, calcification, infection, oil cysts, and accidental injection into a blood vessel. The location where fat is injected, such as the face, breasts, or buttocks, affects the type and seriousness of potential complications. Factors That Increase the Risk of Complications Certain medical conditions and lifestyle habits increase surgical risk. 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: Smoking, vaping, or using nicotine products Poorly controlled diabetes Cardiac, respiratory, renal, liver, or vascular conditions A clotting or bleeding condition, or previous blood clots A high body mass index or significant changes in weight Sleep apnea Conditions affecting the immune system Poor nutrition or significant anemia Previous radiation or surgery in the treatment area 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. Instead, the surgeon must assess whether surgery is reasonably safe and determine what preparation is required. Psychological Effects of Cosmetic Surgery 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. When a patient's expectations exceed the realistic limits of surgery, deeper or longer-lasting disappointment may follow. 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. 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. In suitable cases, the surgeon may delay treatment and advise the patient to seek mental health assessment or counselling first. How to Reduce the Risks of Cosmetic Surgery Although no operation can be made completely risk-free, thorough preparation can improve safety. Choose a properly qualified physician with training and experience relevant to 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. 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. Review the expected healing schedule before arranging employment, trips, strenuous activity, or important occasions. Follow-up care should not be skipped, and abnormal changes should be reported without delay. Avoid judging your recovery against filtered photographs or the healing experience of someone else. Allow swelling and scar tissue to settle fully before considering corrective surgery. How to Select a Cosmetic Surgeon in Canada Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. Patients can search the public register of the applicable college of physicians and surgeons to confirm a doctor's licence, registered specialty, and available practice information. Patients may also ask whether a surgeon is certified in plastic surgery by the Royal College of Physicians and Surgeons of Canada. Royal College certification is valuable, but it should be considered alongside relevant experience, patient communication, emergency planning, surgical surgical aesthetic procedures 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? Based on my health, goals, and anatomy, is this procedure suitable for me? Which problems do your patients experience most often after this operation? What low-frequency, high-impact risks should I know about? Which medical professional will administer and monitor my anesthesia? What happens if I have a complication after business hours? Where would I receive emergency care if needed? 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? What Informed Consent Should Include Informed consent is more than signing a form. The process requires clear communication so that the patient can make a knowledgeable and voluntary choice. The consent process should cover the nature of the procedure, expected benefits, important risks, reasonable alternatives, recovery, limitations, and what could happen without 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. Patients may benefit from writing down information, attending with someone they trust, and reading the documents again at home. When to Seek Help 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: Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness Sudden swelling, pain, redness, or warmth in one leg Significant bleeding or swelling that expands quickly Pain that remains severe despite the prescribed treatment plan A significant fever, shaking chills, expanding redness, or thick discharge Confusion, extreme weakness, or difficulty staying awake A pale, dark, blistered, or unusually cold area of skin Loss of sight, intense eye pain, or an abrupt disturbance in vision 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. Patients should seek immediate care rather than waiting for the surgeon's office when serious bleeding, breathing problems, chest pain, fainting, or another critical symptom occurs. Cosmetic Surgery Costs and Canadian Health Coverage 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. The financial responsibility for postoperative problems should be clarified in advance. 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. Lower upfront fees may become more expensive if postoperative infection, wound breakdown, clotting, implant complications, or revision treatment is required. Evaluating the Advantages 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, emotional, practical, and financial risks. Consider whether you can follow the recovery plan, accept visible scars, manage time away from work, and cope with the possibility of an imperfect result. A responsible surgeon may decline surgery if the patient's risk level is unacceptable, the likely improvement is minimal, or the desired result is unrealistic. A decision not to operate is sometimes the safest and most responsible form of patient care. Deciding Whether Cosmetic Surgery Is Right for You 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. A complete understanding of the likely improvements, procedure limitations, available options, and associated risks helps patients determine whether cosmetic surgery is appropriate for them.
