What to Know About the Possible Complications of Cosmetic Surgery

The shape, proportion, or overall appearance of the face and body can be enhanced through cosmetic surgery. For some people, it can also increase comfort with a physical feature that has caused distress for years. However, every operation involves uncertainty. A careful decision about cosmetic surgery should include a clear understanding of its possible risks. A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. Complications may result from anesthetic medication, bleeding, infection, delayed healing, unexpected reactions, or an individual response to surgery. Certain complications are short-lived and can be treated without major intervention. More serious problems may call for medication, hospital treatment, revision surgery, or ongoing medical follow-up. 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. Most cosmetic procedures are optional, which means you can delay or decline surgery when its risks do not justify its likely 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 procedure being performed, technique used, body area treated, duration of surgery, anesthesia method, and patient health all influence risk. Minor side effects are expected after many procedures. Swelling, bruising, soreness, numbness, tightness, fatigue, and mild drainage may be normal during early healing. 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: Bleeding or a collection of blood called a hematoma An infection in the incision or deeper surgical tissues A collection of fluid called a seroma Clots that form in a leg vein or travel to the lungs Slow wound healing or separation of the incision Scars that become prominent, raised, wide, or uneven Damage to nerves, loss of feeling, or changes in sensation Skin, fat, or tissue loss caused by poor blood supply Reactions to anesthesia, medications, adhesives, or surgical materials Asymmetry, contour problems, or an unwanted appearance Functional changes affecting breathing, movement, or feeling 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 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. As recovery progresses, pain should generally become less intense and easier to control. Prompt medical advice is needed if pain suddenly worsens, begins spreading, or appears with fever, redness, breathing difficulty, or unexpected swelling. Postoperative Swelling and Bruising 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. 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 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. Nerve recovery often improves sensation over time, but normal feeling may not return completely. There is a possibility that altered feeling will not fully resolve. Short-Term Activity Restrictions Patients may need help with transportation, meals, child care, pet care, household work, and personal tasks. Driving, exercise, heavy lifting, swimming, and returning to work may be restricted. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored. Medical and Surgical Risks Postoperative Bleeding and Hematoma A small amount of bleeding may occur around an incision. More significant bleeding can form a hematoma, which is a collection of blood beneath the skin or inside the surgical area. Increasing tenderness, firmness, swelling, discolouration, or an abrupt difference between two sides may indicate a hematoma. 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. Surgical Infection Infection may affect the skin, surgical cut, deeper tissue, or the area surrounding an implant. Possible signs include increasing redness, warmth, swelling, pus-like drainage, worsening pain, fever, chills, or an unpleasant smell. Treatment may involve antibiotics, wound care, drainage, or another operation. Removal can be required when infection develops around a breast implant or surgical device. Infection risk and treatment difficulty may increase with smoking, poorly controlled diabetes, inadequate nutrition, or reduced circulation. Seroma A seroma is a pocket of clear fluid that collects under the skin. It is more common after procedures that create a large space beneath the tissue, such as tummy tuck surgery, body lift surgery, breast surgery, or extensive liposuction. The body may gradually absorb a small seroma without further treatment. Larger ones may need to be drained, sometimes more than once. Untreated fluid can place pressure on the incision, affect healing, or become infected. Blood Clots and Pulmonary Embolism A blood clot that forms in a deep vein, commonly within the leg, is called deep vein thrombosis, or DVT. A pulmonary embolism can occur if a piece of the clot breaks away and reaches the lungs. This is a medical emergency. Long procedures, inactivity, earlier blood clots, some drugs, nicotine use, excess body weight, health conditions, and combined operations can increase the chance of DVT or pulmonary embolism. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable. Poor Wound Healing Slow healing or separation of the incision can occur after cosmetic surgery. Factors such as reduced blood flow, infection, wound tension, nicotine use, medications, and illness may prevent normal healing. Incision problems may need wound care, antibiotics, surgical cleaning, or further corrective surgery. 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. Loss of Tissue From Poor Blood Supply Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and die. Operations that move, tighten, or lift broad areas of tissue can carry a risk of necrosis. 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. It may involve wound care, removal of damaged tissue, skin grafting, reconstructive surgery, or a delayed revision. Risks Related to 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. Potential complications connected with anesthesia include: Postoperative nausea or vomiting Dizziness, mental confusion, or drowsiness that lasts longer than expected Throat discomfort or headache Unexpected reactions to anesthetic or other medications Changes in blood pressure or heart rhythm Breathing difficulties Aspiration of stomach contents into the lungs Dental, lip, or airway damage Serious heart, lung, or neurological complications 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. Leaving out information can make anesthesia and surgery less safe. 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. They may soften and fade over 12 months or longer. The final appearance depends on genetics, skin type, incision tension, infection, sun exposure, wound care, location, and the type of operation. Raised Scars and Keloid Formation A scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. 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. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return. Changes in Skin Colour and Texture 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 A technically successful operation does not always produce the appearance a patient expected. Individual anatomy, skin flexibility, age, past procedures, scarring, and natural asymmetry all affect healing. Possible aesthetic 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 A changing contour as postoperative swelling decreases Movement or poor positioning of an implant Noticeable scars or scars in an unfavourable location Gradual recurrence of skin or tissue laxity Patient dissatisfaction even when the result is medically acceptable Before-and-after images, photographs, and computer simulations may help explain possibilities, but they do not promise a matching result. 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. However, another operation brings new risks. A second operation may be technically harder because previous surgery can leave scar tissue, stiffness, and diminished blood flow. Before proceeding, patients should understand exactly what is included in the surgeon's or clinic's revision policy. 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 surgical risks apply to many operations, but each procedure also has unique concerns. 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. Smoking, vaping, and other nicotine exposure can significantly raise the chance of skin loss and delayed healing. Rhinoplasty Risks 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. A revision nose operation is often more challenging because the first surgery changes the cartilage and creates internal scarring. Possible Complications of Eyelid Surgery Blepharoplasty risks include dry or irritated eyes, temporary blurred vision, difficulty closing the eyelids, eyelid malposition, asymmetry, scarring, bleeding behind the eye, and changes in vision. Severe eye pain or a sudden change in vision requires urgent medical assessment. Risks of Cosmetic Breast Surgery Procedures such as breast augmentation, mastopexy, and breast reduction can change nipple feeling, breast balance, scarring, and future breastfeeding ability. 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. Breast implants are not designed to last for an entire lifetime. Health Canada publishes safety guidance concerning rare illnesses associated with some breast implants, including breast implant-associated anaplastic large cell lymphoma. 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. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated. Risks of Abdominoplasty and Body Lift Surgery 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. Patients may need several weeks of movement restrictions. Fat Grafting Risks Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. The body naturally absorbs some transferred fat, potentially reducing volume or creating asymmetry. Fat grafting may also cause fat necrosis, cyst formation, calcium deposits, infection, oily fluid collections, or unintended injection into circulation. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area. Who May Face Greater Cosmetic Surgery Risks? A patient's health status and daily habits may make complications more likely. A patient may need medical testing, treatment changes, weight management, nicotine cessation, or clearance from another health professional before surgery. The likelihood of complications may increase with: Smoking, vaping, or using nicotine products Poorly controlled diabetes Disease affecting the heart, lungs, kidneys, liver, or circulation 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 Nutritional deficiencies or a low red blood cell count Scar tissue or circulation changes from prior operations or radiation Drugs, vitamins, or supplements that interfere with clotting or tissue repair Expectations that cannot be achieved or unaddressed psychological concerns affecting consent A higher-risk medical history does not necessarily make an operation unsuitable. 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 careful cosmetic surgery consultation should examine why the patient wants the procedure. Possible warning signs include outside pressure, ongoing dissatisfaction despite multiple operations, severe concern about a minor feature, and unrealistic beliefs about total life transformation. Body dysmorphic disorder causes significant distress and preoccupation with appearance flaws that may seem minor or unnoticeable to others. Changing the physical feature does not necessarily treat the underlying mental health condition. A psychological evaluation or professional support may be recommended before surgery when concerns are identified. Ways to Lower Cosmetic Surgery Risks 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. Discuss the surgical location, its safety procedures, infection-control practices, and ability to handle emergencies. 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. Arrange a responsible adult to drive you home and assist during early recovery when required. Do not schedule travel, work duties, exercise, or major events until you understand how long recovery may take. Go to every scheduled postoperative visit and quickly contact the surgical team about unexpected symptoms. Do not compare your healing speed with edited images or another patient's recovery. Wait until healing is mature before deciding whether revision surgery is needed. Choosing a Cosmetic Surgeon in Canada Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. The public directory of the appropriate college plastic surgery in my area of physicians and surgeons can be used to check licensing, specialty registration, and listed practice details. Patients may also ask whether a surgeon is certified in plastic surgery by the Royal College of Physicians and Surgeons of Canada. While certification matters, patients should also assess procedure-specific experience, communication, the quality of the facility, aftercare, and the surgeon's approach to complications. During the consultation, patients may wish to ask: What training and certification do you have? How often do you perform this procedure? 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? Who will provide anesthesia? What happens if I have a complication after business 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? What costs could arise if I need treatment or revision surgery? Understanding Informed Consent Signing paperwork alone does not create true informed consent. It is an ongoing discussion that should give the patient enough information to make a voluntary decision. 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. A patient should never feel rushed to sign. Ask for clarification when a term or complication is unclear. Patients may benefit from writing down information, attending with someone they trust, and reading the documents again at home. 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: Chest pain, shortness of breath, coughing blood, or fainting One-sided leg swelling, tenderness, warmth, or discolouration Heavy bleeding or rapidly increasing swelling Intense pain that does not improve after taking the recommended medicine Fever, chills, redness moving away from the incision, or drainage resembling pus Disorientation, marked weakness, or excessive drowsiness Skin that becomes very pale, dark, blistered, or cold to the touch Loss of sight, intense eye pain, or an abrupt disturbance in vision Ongoing vomiting or difficulty drinking without becoming sick A symptom listed as urgent in the postoperative instructions 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 Procedures performed only to change appearance are generally not covered by provincial or territorial health insurance. 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. Health coverage for complications varies based on medical necessity, treatment setting, and the applicable provincial or territorial insurance plan. Extra costs may arise from transportation, hotels, private nursing, lost income, family care, and corrective procedures. Anyone travelling outside Canada for cosmetic surgery should arrange appropriate postoperative care before coming home. A lower initial price may not include management of infection, wound problems, blood clots, implant complications, or revision surgery. Weighing Cosmetic Surgery Benefits Against Risks Patients should consider surgery only when their goals are achievable, their health is suitable, and they understand the risks and recovery. 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. Recommending against surgery can be a sign of careful and ethical medical practice. How to Make an Informed Cosmetic Surgery Decision Being aware of possible complications is not the same as believing they are certain to happen. 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. A complete understanding of the likely improvements, procedure limitations, available options, and associated risks helps patients determine whether cosmetic surgery is appropriate for them.
