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. 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. Before deciding whether a procedure is suitable, it is essential to understand the risks of cosmetic surgery. A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. 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. 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. Understanding the Risks of Cosmetic Surgery The risks of cosmetic surgery include unwanted outcomes that affect health, physical function, or appearance. 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. It is a problem that goes beyond the expected recovery process and may require medical treatment. Plastic surgery complications may include the following: A hematoma, which is a collection of blood, or other excessive bleeding Incision-site or deep-tissue infection A collection of fluid called a seroma Blood clots in the legs or lungs Delayed wound healing or wound separation Scars that become prominent, raised, wide, or uneven Nerve injury, numbness, or altered sensation Tissue damage or loss resulting from inadequate blood flow Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products Unevenness, contour irregularities, or an unsatisfactory appearance Problems with normal function, including breathing, motion, or sensation The need for additional treatment or revision surgery Although serious complications are rare, they must still be reviewed before surgery. Uncommon but severe risks can include serious infection, substantial bleeding, damage to an organ, cardiac complications, stroke, pulmonary embolism, lasting disability, or death. Expected Short-Term Effects of Cosmetic Surgery Normal recovery often includes temporary discomfort and changes in appearance or sensation. 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. The surgical site can feel tender, tight, sore, or mildly burning during recovery. 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 Swelling is caused by inflammation and fluid moving into the treated tissues. 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. 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. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different. Numbness and Changes in Sensation Small sensory nerves may be stretched, moved, or cut during surgery. Temporary changes such as tingling, numbness, tenderness, or reduced sensation may occur after surgery. Feeling frequently returns as the nerves heal, although full recovery is not certain. There is a possibility that altered feeling will not fully resolve. Temporary Limits on Activity 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. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored. Surgical and Medical Complications Bleeding or Blood Collection 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 After Cosmetic Surgery An infection can develop in the skin, incision, tissue, or around 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. An infected breast implant or other medical device may need to be removed. Patients who smoke or have uncontrolled diabetes, nutritional problems, or poor blood flow may face a higher infection risk and slower recovery. Postoperative Seroma Clear fluid that gathers beneath the skin is known as a seroma. 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. 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 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 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. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate. Poor 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. 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. Smoking, vaping, and other nicotine use can greatly increase risk by narrowing blood vessels and reducing tissue oxygen. 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 Depending on the operation, cosmetic surgery can involve local anesthetic, sedating medication, general anesthesia, or multiple methods together. 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 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 Severe cardiac, respiratory, or neurological problems Patients must provide complete information about prescriptions, non-prescription drugs, vitamins, supplements, cannabis, alcohol, nicotine, allergies, earlier anesthesia problems, and medical conditions before surgery. The safety of the operation can be reduced when important health information is omitted. 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. 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. The final appearance depends on genetics, skin type, incision tension, infection, sun exposure, wound care, location, and the type of operation. Hypertrophic Scars and Keloids Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. Keloid tissue spreads past the edges of the initial incision. People with a personal or family history of abnormal scarring should tell their surgeon before surgery. Possible treatments include silicone products, pressure therapy, copyright injections, laser treatment, or scar revision. Although treatment can make a scar less noticeable, recurrence of abnormal tissue remains possible. Changes in Skin Colour and Texture Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. Some of these changes resolve over time, while others can last permanently. The chance of pigment or texture problems varies according to skin characteristics and surgical technique. Cosmetic Outcome Risks and Patient Dissatisfaction A procedure can be medically and technically successful while still producing a result the patient did not anticipate. 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: Persistent asymmetry Visible dents, bulges, or contour differences Under-correction or over-correction A result that appears unnatural or excessively tight Changes in shape as swelling settles An implant that shifts, rotates, or sits incorrectly Scarring that is prominent or difficult to conceal A return of looseness or sagging with age and time Disappointment with an outcome that falls within an acceptable surgical range 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 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. The first surgical fee may not cover a revision surgeon, facility charges, anesthesia, new implants, prescriptions, travel, or lost work time. Risks Associated With Specific Cosmetic Procedures General risks are present across cosmetic surgery, while individual procedures introduce additional concerns. Risks of Facelift and Neck Lift Surgery Hematoma, facial nerve injury, hairline alteration, hair loss around incisions, skin necrosis, contour problems, earlobe changes, loss of feeling, facial weakness, and visible scarring are among the risks of facelift and neck lift surgery. Nicotine use can greatly increase the risk of skin-healing problems. 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. The final shape may take a year or longer to become clear. Scar formation and altered cartilage can make secondary rhinoplasty more complex. Blepharoplasty Risks 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. A patient should seek urgent care if severe eye pain or an abrupt change in vision occurs. Possible Breast Procedure Complications Procedures such as breast augmentation, mastopexy, and breast reduction can change nipple feeling, breast balance, scarring, and future breastfeeding ability. 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. These include capsular contracture, implant rupture, deflation, rippling, movement, rotation, pain, and the need for future monitoring or surgery. 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 Possible problems after liposuction include uneven contours, indentations, rippled or loose skin, changes in fluid balance, reduced feeling, seroma, infection, internal damage, fat embolism, and toxicity from lidocaine. High-volume liposuction and treatment of several regions can place greater stress on the body and make recovery more demanding. Possible Tummy Tuck and Body Lift Complications Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. Risks include seroma, blood clots, infection, skin loss, wound separation, numbness, prominent scarring, and changes to the position or shape of the belly button. Activity and lifting restrictions can remain in place for a number of weeks. Risks of Fat Transfer Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. 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 location where fat is injected, such as the face, breasts, or buttocks, affects the type and seriousness of potential complications. Who May Face Greater Cosmetic Surgery Risks? Certain medical conditions and lifestyle habits increase surgical risk. Preoperative preparation may include laboratory testing, medication changes, weight management, stopping nicotine, or obtaining medical clearance. The likelihood of complications may increase with: Cigarette smoking, vaping, or any form of nicotine use Poorly controlled diabetes Cardiac, respiratory, renal, liver, or vascular conditions Past DVT, pulmonary embolism, or a diagnosed bleeding disorder A high body mass index or significant changes in weight Obstructive 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 Unrealistic expectations or untreated mental health concerns that affect decision-making Having a risk factor does not always mean surgery is impossible. Instead, the surgeon must assess whether surgery is reasonably safe and determine what preparation is required. Psychological Effects of Cosmetic Surgery An operation performed for appearance can influence a patient's mental and emotional state in addition to the body. During recovery, patients can become anxious or discouraged because they look swollen, feel tired, and cannot resume normal activities. The term postoperative blues is sometimes used to describe this temporary decline in mood. 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 careful cosmetic surgery consultation should examine why the patient wants the procedure. 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 personalized plastic surgery 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. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation. Reducing the Chance of Surgical Complications Risk cannot be removed completely, but careful planning can make cosmetic surgery safer. Choose a properly qualified physician with training and experience relevant to the procedure. Verify the physician's registration and standing through the medical regulatory authority in your province or territory. Find out which facility will be used and whether it has suitable emergency plans, safety standards, and infection prevention measures. Provide a complete medical history, including medications, supplements, nicotine, cannabis, alcohol, allergies, and prior operations. Follow instructions about fasting, medication changes, testing, and stopping nicotine. When needed, organize transportation and early postoperative support from a responsible adult. Understand the recovery timeline before booking work, travel, exercise, or major events. 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. Do not make an early decision about revision, because the tissues may require many months to heal and stabilize. Finding a Qualified Canadian Cosmetic Surgeon Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. Patients may verify a physician's licence and registered specialty through the online register maintained by their provincial or territorial regulator. 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. Questions to ask during a cosmetic surgery consultation include: What professional education and certifications have you completed? How many times have you carried out this operation? Based on my health, goals, and anatomy, is this procedure suitable for me? What are the most common complications in your practice? What rare but serious risks should I understand? Which medical professional will administer and monitor my anesthesia? How can I obtain care if a problem develops at night or on a weekend? Where would I receive emergency care if needed? What follow-up visits are included? Which additional expenses would I be responsible for if a complication or revision occurs? Understanding Informed Consent Informed consent involves more than placing a signature on a document. It should be a continuing conversation that allows the patient to decide freely after receiving adequate information. A proper consent discussion includes the procedure itself, expected improvement, significant complications, alternative options, recovery requirements, limitations, and the choice to decline treatment. The surgeon should also explain risks that may have particular importance because of the patient's occupation, health, daily activities, or individual goals. Patients should have enough time to review consent information without being pressured. Ask for clarification when a term or complication is unclear. Taking notes, involving a support person, and reviewing written material outside the clinic can support an informed decision. Postoperative Warning Signs 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. Urgent warning signs may include: Breathing problems, chest discomfort, bloody coughing, or fainting Unexpected pain, swelling, redness, or heat affecting one leg Uncontrolled bleeding or a sudden increase in swelling Severe pain that is not controlled by prescribed medication High fever, chills, spreading redness, or pus-like drainage Mental confusion, severe weakness, or unusual inability to remain alert A pale, dark, blistered, or unusually cold area of skin 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. Severe breathing difficulty, chest pain, unconsciousness, heavy bleeding, and other emergency symptoms should not wait until normal clinic hours. Financial Risks and Health Coverage 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. The financial responsibility for postoperative problems should be clarified in advance. 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. 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. Balancing the Benefits and Risks of Cosmetic Surgery A sound decision about cosmetic surgery requires realistic expectations, appropriate health, informed consent, and knowledge of the healing process. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection. Patients should carefully weigh likely improvements against health risks, emotional effects, recovery demands, and financial costs. Think about your ability to obey postoperative instructions, live with scars, take enough time off, and emotionally manage an outcome that is not ideal. A responsible surgeon may decline surgery if the patient's risk level is unacceptable, the likely improvement is minimal, or the desired result is unrealistic. A decision not to operate is sometimes the safest and most responsible form of patient care. Making an Informed Decision Understanding the risks of cosmetic surgery does not mean assuming that complications will occur. It means making a thoughtful decision based on accurate information rather than advertising, social media trends, or price alone. 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.
