What to Know About the Possible Complications of Cosmetic Surgery

The shape, proportion, or overall appearance of the face and body can be improved through cosmetic surgery. It may also help a person feel more comfortable with a feature that has bothered them for years. Even so, every surgical procedure involve some uncertainty. 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. Certain complications are temporary and can be treated without major intervention. More serious problems may call for medication, hospital treatment, revision surgery, or ongoing medical follow-up. Canadian patients should receive understandable information about benefits, material risks, available alternatives, recovery demands, and the possible effects of choosing no treatment. During a careful consultation, patients should be able to consider the facts without being rushed. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits. What Risks Can Cosmetic Surgery Involve? 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. Expected healing effects and surgical complications are different. A complication extends beyond normal recovery and may need medical care. Possible complications of plastic surgery include: A hematoma, which is a collection of blood, or other excessive bleeding An infection in the incision or deeper surgical tissues Fluid buildup, known as a seroma 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 Damage to nerves, loss of feeling, or changes in sensation Tissue damage or loss resulting from inadequate blood flow Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials Unevenness, contour irregularities, or an unsatisfactory appearance Problems with normal function, including breathing, motion, or sensation Additional medical treatment or a revision operation Serious complications are uncommon, but they are still important to discuss. Rare risks may include severe infection, major blood loss, organ injury, heart problems, stroke, pulmonary embolism, permanent disability, or death. Common Short-Term Effects After Cosmetic Surgery Normal recovery often includes temporary discomfort and changes in appearance or sensation. Patients should understand what is expected so they can tell the difference between routine recovery and a warning sign. Pain and Tenderness Pain levels vary by procedure and patient. Tightness, aching, burning, or tenderness may occur near the surgical area. Pain should usually become easier to manage as healing continues. Patients should quickly report severe or spreading pain, especially when it is accompanied by fever, redness, shortness of breath, or unusual swelling. Bruising and Tissue Swelling Inflammation and the movement of fluid into surgical tissues cause swelling. For several weeks or even months, swelling may conceal the true result of surgery. Small blood vessels can release blood under the skin, creating bruising. Facial procedures, liposuction, breast surgery, and body contouring can all cause visible swelling and bruising. 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 During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Some procedures commonly cause short-term numbness, tingling, increased sensitivity, or a decrease in feeling. Feeling frequently returns as the nerves heal, although full recovery is not certain. There is a possibility that altered feeling will not fully resolve. Activity Limitations During Recovery Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. Restrictions may apply to driving, physical activity, lifting, swimming, and work. Failing to follow activity restrictions may raise the risk of bleeding, swelling, wound breakdown, and other problems. Surgical and Medical Complications Postoperative Bleeding and Hematoma Minor bleeding near a surgical incision can occur during early recovery. 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. Depending on its size and symptoms, a hematoma may be watched or medically drained. In certain cases, the patient may need to return to the operating room. Infection After Cosmetic Surgery 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. If a breast implant or another implanted device becomes infected, removal may be necessary. Patients who smoke or have uncontrolled diabetes, nutritional problems, or poor blood flow may face a higher infection risk and slower recovery. Seroma A seroma is a pocket of clear fluid that collects under the skin. Seromas occur more often after operations that leave a broad space under the tissue, including tummy tuck surgery, body lifts, breast procedures, and extensive liposuction. The body may gradually absorb a small seroma without further treatment. A larger seroma may require drainage on one or several occasions. Untreated fluid can place pressure on the incision, affect healing, or become infected. Blood Clots and Pulmonary Embolism Deep vein thrombosis, or DVT, occurs when a blood clot forms in a deep vein, often in the 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. Factors that may raise blood clot risk include lengthy surgery, reduced mobility, a history of clots, particular medications, nicotine exposure, obesity, certain illnesses, and multiple procedures performed together. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable. Poor Wound Healing Slow healing or separation of the incision can occur after cosmetic surgery. Reduced blood supply, infection, tension on the wound, nicotine exposure, certain medications, and medical conditions can interfere with healing. Treatment for a wound complication can include specialized dressings, antibiotic medication, removal of unhealthy tissue, or another operation. When a wound is left to close slowly from its deeper layers toward the surface, the process is called healing by secondary intention. The recovery period may be extended, and the final scar may be more prominent. Skin or Tissue Necrosis Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and die. This complication can occur after procedures that lift, tighten, or reposition large sections of tissue. Nicotine exposure is an important avoidable risk because it constricts blood vessels and limits oxygen reaching the tissues. Treatment depends on the amount of tissue affected. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery. Potential Complications of Anesthesia Local anesthesia, sedation, general anesthesia, or a combination may be used during cosmetic surgery. 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, mental confusion, or drowsiness that lasts longer than expected A headache or irritation of the throat An allergic response or adverse drug reaction Fluctuations in blood pressure or disturbances in heartbeat Breathing difficulties 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 Before surgery, patients should disclose all prescription drugs, over-the-counter medications, vitamins, supplements, cannabis products, alcohol use, nicotine use, allergies, past anesthesia reactions, and relevant medical conditions. The safety of the operation can be reduced when important health information is omitted. Changes in Scarring, Colour, and Skin Texture A surgical procedure that breaks the skin will always leave some degree of scarring. Surgeons usually place incisions where they can be hidden within natural folds, hairlines, or clothing, but a scar cannot be erased completely. 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. How a scar eventually looks is affected by heredity, skin type, wound tension, infection, ultraviolet exposure, aftercare, incision placement, and the operation performed. Hypertrophic Scars and Keloids A hypertrophic scar becomes thick or raised but stays within the original wound. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. People with a personal or family history of abnormal scarring should tell their surgeon before surgery. 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. Skin Colour and Texture Changes The treated skin may develop colour changes, redness, noticeable blood vessels, dimpling, firmness, or textural differences. Alterations in colour or texture may improve, but they can also remain long term. The risk can differ by skin tone and by the type of procedure performed. Cosmetic Outcome Risks and Patient Dissatisfaction Even when surgery is performed correctly, the final appearance may not match the patient's expectations. The body's response is shaped by age, anatomy, skin quality, earlier surgery, scar development, and normal side-to-side differences. Potential cosmetic outcome concerns include: Unevenness that remains after healing Irregular or uneven body contours A result that is under-treated or over-treated A result that appears unnatural or excessively tight Changes in shape as swelling settles Implant position problems Scarring that is prominent or difficult to conceal Gradual recurrence of skin or tissue laxity Patient dissatisfaction even when the result is medically acceptable 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. Corrective and Revision Surgery When problems occur or the outcome may benefit from improvement, revision cosmetic surgery can be considered. Revision surgery carries risks of its own. Scar tissue can make the procedure more complex, and the tissues may have less blood supply or flexibility than they did before the first surgery. 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 General surgical risks apply to many operations, but each procedure also has unique concerns. Facelift and Neck Lift Risks 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. A revision nose operation is often more challenging because the first surgery changes the cartilage and creates internal scarring. Possible Complications of Eyelid Surgery 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. Breast Surgery Risks 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. 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. Patients should not assume that breast implants will remain in place permanently without further care. Health Canada also provides safety information about uncommon conditions linked with certain breast implants, including breast implant-associated anaplastic large cell lymphoma. Liposuction Risks 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 plastic surgery nearby 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. Risks of Fat Transfer 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. Who Has a Higher 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. Factors associated with higher surgical risk include: Smoking, vaping, or using nicotine 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 A diagnosed or suspected sleep-related breathing disorder Immune system disorders Poor nutrition or significant anemia Previous radiation or surgery in the treatment area Drugs, vitamins, or supplements that interfere with clotting or tissue repair Expectations that cannot be achieved or unaddressed psychological concerns affecting consent The presence of one or more risk factors does not automatically prevent cosmetic surgery. It means the surgeon must decide whether the procedure can be performed safely and whether changes are needed before proceeding. Emotional and Mental Health Considerations The effects of cosmetic surgery may be psychological and emotional, not only physical. Swelling, bruising, fatigue, and temporary lifestyle restrictions may leave some patients feeling worried, frustrated, or low. The term postoperative blues is sometimes used to describe this temporary decline in mood. 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. Warning signs may include pressure from another person, repeated procedures without satisfaction, extreme focus on a minor feature, or the belief that one operation will completely transform a person's life. Intense and persistent concern about perceived physical defects may be a sign of body dysmorphic disorder, a recognized mental health condition. 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. Reducing the Chance of Surgical Complications Risk cannot be removed completely, but careful planning can make cosmetic surgery safer. Select a qualified doctor who has appropriate education and substantial experience performing the procedure. Check the doctor's licence, registration, and professional standing with the applicable provincial or territorial medical regulator. Find out which facility will be used and whether it has suitable emergency plans, safety standards, and infection prevention measures. 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. Go to every scheduled postoperative visit and quickly contact the surgical team about unexpected symptoms. 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. Another useful question is whether the doctor holds plastic surgery certification from 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 training and certification do you have? How many times have you carried out this operation? Based on my health, goals, and anatomy, is this procedure suitable for me? What complications are seen most frequently with this procedure in your practice? What rare but serious risks should I understand? Who will provide anesthesia? Who should I contact if I experience a complication outside normal clinic hours? What emergency plan is in place if I need urgent medical treatment? How many postoperative appointments are provided as part of the surgical plan? 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. 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. Postoperative Warning Signs The surgeon's office should explain which symptoms require attention and copyright the appropriate provider. Contact the clinic promptly when symptoms are unexpected, worsening, or different from the recovery plan. Potential emergency signs after cosmetic surgery include: Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness One-sided leg swelling, tenderness, warmth, or discolouration Uncontrolled bleeding or a sudden increase in swelling Severe pain that is not controlled by prescribed medication A significant fever, shaking chills, expanding redness, or thick discharge Disorientation, marked weakness, or excessive drowsiness Possible tissue damage shown by abnormal colour, blistering, or low skin temperature Sudden vision loss, severe eye pain, or major visual changes Repeated vomiting or an inability to keep fluids down 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. 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. Financial Considerations for Cosmetic Surgery in Canada Procedures performed only to change appearance are generally not covered by provincial or territorial health insurance. Out-of-pocket expenses may include the surgeon, anesthesia provider, operating room, medical devices, recovery clothing, prescriptions, laboratory work, and follow-up items. Complication-related costs should be discussed before surgery. 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. Patients should budget for possible travel, lodging, caregiving, time away from employment, child care, and future revision surgery. Anyone travelling outside Canada for cosmetic surgery should arrange appropriate postoperative care before coming home. An inexpensive overseas package may exclude the cost of treating infection, poor healing, DVT, implant problems, and corrective operations. Evaluating the Advantages and Risks of Cosmetic Surgery Patients should consider surgery only when their goals are achievable, their health is suitable, and they understand the risks and recovery. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection. Take time to compare the expected benefit with the medical, emotional, practical, and financial risks. The decision should account for recovery restrictions, permanent scarring, employment absence, and the possibility that the final result may fall short of expectations. When complications are too likely, benefits are small, or expectations cannot be met safely, an experienced surgeon may recommend against operating. This is an important part of responsible care. 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. A safer decision involves understanding the procedure, identifying individual risk factors, checking the surgeon's qualifications, discussing concerns, and organizing postoperative care. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
