What to Know About the Possible Complications of Cosmetic Surgery

Cosmetic surgery can enhance the shape, proportion, or appearance of the face and body. 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. Most patients recover without a major complication, but no surgeon can promise a perfect result or a risk-free operation. 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. In other cases, a complication can require drugs, hospital care, another operation, or extended monitoring. 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. Cosmetic surgery is usually elective, so you should feel comfortable delaying or declining it when the risks outweigh the likely benefits. Understanding the Risks of Cosmetic Surgery Any undesirable medical, functional, or cosmetic result connected with an operation may be considered a cosmetic surgery risk. Risk levels vary according to the procedure, surgical method, treatment area, operation length, anesthesia type, and the patient's general health. Minor side effects are expected after many procedures. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. A true complication is not the same as an expected side effect. It is an unexpected problem that exceeds routine healing and can require treatment. Plastic surgery complications may include the following: A hematoma, which is a collection of blood, or other excessive bleeding Infection at the incision or within deeper tissue Fluid buildup, known as a seroma Clots that form in a leg vein or travel to the lungs An incision that heals poorly, slowly, or begins to open Visible scarring that may be thick, widened, raised, or irregular Damage to nerves, loss of feeling, or changes in sensation Loss of skin, fat, or other tissue because of reduced circulation Reactions to anesthesia, medications, adhesives, or surgical materials Aesthetic concerns such as asymmetry, poor contours, or an unwanted result Changes in function, such as breathing, movement, or sensation Additional medical treatment or a revision operation Serious complications are uncommon, but they are still important to discuss. Possible rare complications include severe infection, major hemorrhage, organ damage, heart problems, stroke, a blood clot in the lungs, permanent impairment, and death. Common Short-Term Effects After Cosmetic Surgery Some discomfort and physical change are part of normal healing. 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. 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 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. Patients undergoing face surgery, breast surgery, liposuction, or body contouring may experience noticeable bruising and swelling. The outcome of surgery should not be assessed before healing has progressed. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different. Altered Sensation and Numbness Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. Some procedures commonly cause short-term numbness, tingling, increased sensitivity, or a decrease in feeling. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. In some cases, changes in sensation may be permanent. 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. Failing to follow activity restrictions may raise the risk of bleeding, swelling, wound breakdown, and other problems. Potential Surgical Complications Bleeding and Hematoma A small amount of bleeding may occur around an incision. Heavier bleeding may create a hematoma, a pocket of blood beneath the skin or within the treated area. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body. 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 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. 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. Fluid Buildup or Seroma Clear fluid that gathers beneath the skin is known as a seroma. 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. Small seromas may resolve as the body absorbs the fluid. 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, known as DVT, develops when a clot forms in one of the body's deep veins, usually in a leg. A pulmonary embolism can occur if a piece of the clot breaks away and reaches the lungs. This is a medical emergency. 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. Incision problems may need wound care, antibiotics, surgical cleaning, or further corrective surgery. When a wound is left to close slowly from its deeper layers toward the surface, the process is called healing by secondary intention. Healing in this way often takes more time and can result in a more noticeable scar. Skin or Tissue Necrosis Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to die. Tissue loss may occur after procedures involving extensive lifting, tightening, or repositioning. 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. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery. Risks Related to Anesthesia Local anesthesia, sedation, general anesthesia, or a combination may be used during cosmetic surgery. The most suitable anesthesia plan is based on the type of surgery, patient health history, procedure duration, and location where surgery takes place. Potential complications connected with anesthesia include: Postoperative nausea or vomiting Light-headedness, confusion, or extended sleepiness Throat discomfort or headache Unexpected reactions to anesthetic or other medications Changes in blood pressure or heart rhythm Problems with breathing Aspiration, which occurs when material from the stomach reaches the lungs Injury to the teeth, lips, mouth, or airway Serious heart, lung, or neurological complications 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. Changes in Scarring, Colour, and Skin Texture Whenever an incision is made through the skin, a scar will form. Incisions are often positioned in natural creases, along hairlines, or beneath clothing, although no scar can be removed entirely. 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 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. Raised or visible scars may be treated with silicone, compression, copyright injections, laser procedures, or surgical revision. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return. Skin Colour and Texture Changes Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. These effects may be temporary or permanent. A patient's skin tone and the procedure being performed can influence the likelihood of these changes. Aesthetic Risks and Unsatisfactory Results A Cosmetic North 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: Ongoing asymmetry Irregular or uneven body contours A result that is under-treated or over-treated An artificial-looking or over-tightened outcome Alterations in shape while swelling resolves An implant that shifts, rotates, or sits incorrectly Visible or poorly placed scars Gradual recurrence of skin or tissue laxity Disappointment with an outcome that falls within an acceptable surgical range Visual examples and digital imaging can guide consultation discussions, although no patient can be guaranteed the same 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. A second procedure introduces another set of surgical risks. 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. 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. Risks Associated With Specific Cosmetic Procedures Although many operations share common complications, every cosmetic procedure has its own specific risks. Risks of Facelift and Neck Lift Surgery 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. Nicotine use can greatly increase the risk of skin-healing problems. Possible Rhinoplasty Complications 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. Revision rhinoplasty can be more difficult because of scar tissue and changes to the cartilage. Possible Complications of Eyelid Surgery Possible eyelid surgery complications include eye dryness, irritation, short-term blurred vision, incomplete eyelid closure, abnormal lid position, unevenness, scars, bleeding behind the eye, and visual changes. Immediate medical evaluation is needed for intense eye pain or a sudden visual disturbance. Breast Surgery Risks Procedures such as breast augmentation, mastopexy, and breast reduction can change nipple feeling, breast balance, scarring, and future breastfeeding ability. Other risks include hematoma, infection, fat necrosis, delayed healing, and changes in nipple or areola position. Implant-based breast surgery involves long-term risks beyond the normal surgical recovery period. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. 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. Possible Liposuction Complications Liposuction complications may include contour irregularities, dents, rippling, loose skin, fluid imbalance, numbness, seroma, infection, internal injury, fat embolism, and lidocaine toxicity when local anesthetic is used. High-volume liposuction and treatment of several regions can place greater stress on the body and make recovery more demanding. Tummy Tuck and Body Lift Risks 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. Recovery may involve several weeks of limited movement and physical activity. Possible Fat Grafting Complications 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. 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 Has a Higher Risk of Complications? 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. Risk factors may include: Smoking, vaping, or using nicotine products Poorly controlled diabetes Heart, lung, kidney, liver, or blood vessel disease A clotting or bleeding condition, or previous blood clots Obesity, unstable weight, or recent major weight loss or gain Sleep apnea Immune disorders or reduced immune function Nutritional deficiencies or a low red blood cell count Earlier surgery or radiation therapy involving the same area Medications or supplements that affect bleeding or healing Mental health concerns or unrealistic goals that interfere with informed 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 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. Significant dissatisfaction is more likely when the expected transformation is not medically achievable. Although surgery can alter appearance, it cannot promise self-confidence, fix relationships, ensure professional success, or resolve wider life difficulties. 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. An operation may fail to resolve the deeper psychological distress. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation. 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. 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. Follow instructions about fasting, medication changes, testing, and stopping nicotine. 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. 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 In Canada, physicians are licensed and regulated by provincial and territorial authorities. The public directory of the appropriate college 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. Royal College certification is valuable, but it should be considered alongside relevant experience, patient communication, emergency planning, surgical environment, and postoperative support. During the consultation, patients may wish to ask: What professional education and certifications have you completed? How frequently is this specific procedure performed in your practice? 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 rare but serious risks should I understand? Who is responsible for anesthesia care during the operation? 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? Could I face extra surgeon, facility, anesthesia, medication, or revision fees? What Informed Consent Should Include 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. Patients should be informed about how the operation works, its likely benefits, material risks, alternatives, healing process, limits, and the possible consequences of no surgery. Risks that are especially relevant to the patient's health, job, lifestyle, or personal priorities should also be discussed. No one should be pushed into signing a surgical consent form quickly. 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. Warning Signs After Cosmetic Surgery The surgeon's office should explain which symptoms require attention and copyright the appropriate provider. Unexpected or worsening symptoms that fall outside the recovery instructions should be reported without delay. Symptoms that may require urgent care include: Chest pain, shortness of breath, coughing blood, or fainting One-sided leg swelling, tenderness, warmth, or discolouration 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 Disorientation, marked weakness, or excessive drowsiness 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 symptom the surgical team identified as an emergency Emergency medical services should be contacted immediately for potentially life-threatening complications. Severe breathing difficulty, chest pain, unconsciousness, heavy bleeding, and other emergency symptoms should not wait until normal clinic hours. Cosmetic Surgery Costs and Canadian Health Coverage Canadian provincial and territorial health plans generally do not pay for operations performed solely for cosmetic reasons. Out-of-pocket expenses may include the surgeon, anesthesia provider, operating room, medical devices, recovery clothing, prescriptions, laboratory work, and follow-up items. The financial responsibility for postoperative problems should be clarified in advance. 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. Travel, accommodation, nursing assistance, missed work, child care, and revision surgery can create additional expenses. Anyone travelling outside Canada for cosmetic surgery should arrange appropriate postoperative care before coming home. Lower upfront fees may become more expensive if postoperative infection, wound breakdown, clotting, implant complications, or revision treatment is required. Weighing Cosmetic Surgery Benefits Against Risks A sound decision about cosmetic surgery requires realistic expectations, appropriate health, informed consent, and knowledge of the healing process. A suitable patient recognizes that improvement is possible, but perfection is not. Patients should carefully weigh likely improvements against health risks, emotional effects, recovery demands, and financial costs. 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. 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. Before surgery, research the operation, assess your health risks, verify medical credentials, ask thorough questions, and prepare for the complete healing period. A complete understanding of the likely improvements, procedure limitations, available options, and associated risks helps patients determine whether cosmetic surgery is appropriate for them.
