What to Know About the Risks of Cosmetic Surgery

The shape, proportion, or overall appearance of the face and body can be enhanced through cosmetic surgery. A person may also feel more at ease with a long-standing appearance concern after cosmetic surgery. Cosmetic surgery may offer benefits, but no operation is entirely predictable. Before deciding whether a procedure is suitable, it is essential to understand the risks of cosmetic surgery. Although most patients heal without serious problems, no surgeon can guarantee perfection or eliminate every surgical risk. Problems can occur because of anesthesia, bleeding, infection, poor healing, an unexpected reaction, or the way the body responds to surgery. Certain complications are short-lived and can be treated without major intervention. 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. A careful consultation gives you time to consider this information without pressure. 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 Are the Risks of Cosmetic Surgery? Cosmetic surgery risks include any unwanted medical, functional, or aesthetic outcome linked to an operation. The procedure being performed, technique used, body area treated, duration of surgery, anesthesia method, and patient health all influence risk. Many cosmetic procedures are followed by minor expected side effects. Swelling, bruising, soreness, numbness, tightness, fatigue, and mild drainage may be normal during early healing. A true complication is not the same as an expected side effect. It is a problem that goes beyond the expected recovery process and may require medical treatment. Possible complications of plastic surgery include: A hematoma, which is a collection of blood, or other excessive bleeding Infection at the incision or within deeper tissue Seroma formation, which involves fluid collecting beneath the tissue Blood clots in the legs or lungs Delayed wound healing or wound separation Scars that become prominent, raised, wide, or uneven Nerve-related problems, including numbness or unusual 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 Problems with normal function, including breathing, motion, or sensation A need for further care or corrective surgery 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 Some discomfort and physical change are part of normal healing. Knowing what normal healing looks like helps patients recognize when a symptom may be a warning sign. Postoperative Pain and Tenderness Each patient experiences pain differently, and some operations cause more discomfort than others. 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. Swelling and Bruising Swelling is caused by inflammation and fluid moving into the treated tissues. The early result can remain difficult to assess until swelling subsides over the following weeks or months. Small blood vessels can release blood under the skin, creating bruising. Patients undergoing face surgery, breast surgery, liposuction, or body contouring may experience noticeable bruising and swelling. Patients are advised to avoid making early judgments about their final appearance. Residual swelling can change shape, symmetry, and skin texture during recovery. Changes in Feeling After Surgery During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Temporary numbness, tingling, sensitivity, or reduced feeling is common after some operations. Nerve recovery often improves sensation over time, but normal feeling may not return completely. Permanent sensory changes are possible. Temporary Limits on Activity Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. Patients may be temporarily unable to drive, exercise, lift heavy objects, swim, or resume their jobs. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored. Medical and Surgical Risks Bleeding and Hematoma A limited amount of bleeding around the incision may be expected. When bleeding is more substantial, blood may collect under the skin or in the surgical site and form a hematoma. Increasing tenderness, firmness, swelling, discolouration, or an abrupt difference between two sides may indicate a hematoma. Some hematomas can be observed, while others must be drained. A return to the operating room may be necessary in more serious cases. Infection An infection can develop in the skin, incision, tissue, or around an implant. Possible signs include increasing redness, warmth, swelling, pus-like drainage, worsening pain, fever, chills, or an unpleasant smell. Antibiotics, specialized wound care, drainage, or further surgery may be needed to treat an infection. If a breast implant or another implanted device becomes infected, removal may be necessary. Smoking, uncontrolled diabetes, poor nutrition, and problems with blood circulation can raise the risk of infection or make it harder to treat. Seroma A seroma develops when a pocket of clear fluid forms under the surgical tissues. Procedures such as abdominoplasty, body lift surgery, breast surgery, and large-area liposuction may have a greater seroma risk because they create space beneath the tissue. A minor fluid collection can sometimes disappear as the body reabsorbs it. Larger ones may need to be drained, sometimes more than once. If fluid is not treated, it may strain the incision, delay healing, or lead to infection. Blood Clot Complications A blood clot that forms in a deep vein, commonly plastic and cosmetic surgery 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. A pulmonary embolism requires emergency medical care. Risk may increase with long operations, limited movement, previous blood clots, certain medications, nicotine use, obesity, some medical conditions, and combining multiple procedures. Depending on the patient, preventive steps may involve getting up early, using compression equipment or garments, staying hydrated, or taking prescribed blood thinners. Poor Wound Healing A surgical wound may take longer than expected to close or may start to open. Healing may be impaired by poor circulation, infection, pressure on the incision, nicotine, some medicines, or underlying health conditions. 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. Healing in this way often takes more time and can result in a more noticeable scar. 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. 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. The extent of tissue damage determines which treatment is required. 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. The most suitable anesthesia plan is based on the type of surgery, patient health history, procedure duration, and location where surgery takes place. Possible anesthesia-related problems include: Postoperative nausea or vomiting Dizziness, mental confusion, or drowsiness that lasts longer than expected Headache or sore throat Allergic or medication reactions Changes in blood pressure or heart rhythm Breathing difficulties Stomach contents entering the lungs, known as aspiration Injury to the teeth, lips, mouth, or airway 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. Surgeons usually place incisions where they can be hidden within natural folds, hairlines, or clothing, but a scar cannot be erased completely. Scars often appear red, raised, firm, or darker during early healing. Scars may require a year or more to flatten, soften, and become less noticeable. The final appearance depends on genetics, skin type, incision tension, infection, sun exposure, wound care, location, and the type of operation. Raised Scars and Keloid Formation 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. A history of hypertrophic scars or keloids, whether personal or familial, should be discussed before an operation. 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 Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin texture. These effects may be temporary or permanent. A patient's skin tone and the procedure being performed can influence the likelihood of these changes. The Risk of an Unwanted Cosmetic Result 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: Ongoing asymmetry Uneven contours or visible irregularities Under-correction or over-correction A result that appears unnatural or excessively tight A changing contour as postoperative swelling decreases Implant position problems Noticeable scars or scars in an unfavourable location Recurrence of sagging or tissue laxity over time 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. Revision Cosmetic Surgery Revision surgery may be considered when a complication occurs or when the result can be improved. Revision surgery carries risks of its own. A second operation may be technically harder because previous surgery can leave scar tissue, stiffness, and diminished blood flow. Patients should ask what the clinic's revision policy covers. The first surgical fee may not cover a revision surgeon, facility charges, anesthesia, new implants, prescriptions, travel, or lost work time. Procedure-Specific Cosmetic Surgery Risks Although many operations share common complications, every cosmetic procedure has its own specific risks. 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. Smoking, vaping, and other nicotine exposure can significantly raise the chance of skin loss and delayed healing. Risks of Nose Surgery 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. Eyelid Surgery 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. 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. 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. These include capsular contracture, implant rupture, deflation, rippling, movement, rotation, pain, and the need for future monitoring or surgery. 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 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. Risks of Abdominoplasty and Body Lift Surgery Tummy tuck and body lift procedures require long incisions and repositioning of broad tissue areas. Possible complications include fluid buildup, DVT, infection, tissue loss, incision opening, reduced sensation, visible scars, and changes in navel shape or placement. 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. Some of the transferred fat will be absorbed, which can affect volume and symmetry. Fat grafting may also cause fat necrosis, cyst formation, calcium deposits, infection, oily fluid collections, or unintended injection into circulation. Fat transfer risks vary according to whether the treatment area is the face, breast, buttocks, or another body region. 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. Factors associated with higher surgical risk include: Smoking, vaping, or using nicotine products Poorly controlled diabetes Cardiac, respiratory, renal, liver, or vascular conditions A clotting or bleeding condition, or previous blood clots Obesity, unstable weight, or recent major weight loss or gain Obstructive sleep apnea Immune disorders or reduced immune function 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 Mental health concerns or unrealistic goals that interfere with informed decision-making The presence of one or more risk factors does not automatically prevent cosmetic surgery. It means the surgeon must decide whether the procedure can be performed safely and whether changes are needed before proceeding. Psychological Effects of Cosmetic Surgery The effects of cosmetic surgery may be psychological and emotional, not only physical. 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. 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 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. Surgery may not relieve the underlying concern. 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. Ask where the procedure will be performed and what safety, emergency, and infection-control systems are available. Give the surgical team accurate information about diagnoses, operations, prescriptions, supplements, substances, and allergies. Carefully follow all directions related to eating, drinking, preoperative tests, medication adjustments, and nicotine cessation. 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. 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. Choosing a Cosmetic Surgeon in Canada Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. Patients can search the public register of the applicable college of physicians and surgeons to confirm a doctor's licence, registered specialty, and available practice information. Patients may also ask whether a surgeon is certified in plastic surgery by the Royal College of Physicians and Surgeons of Canada. Royal College certification is valuable, but it should be considered alongside relevant experience, patient communication, emergency planning, surgical environment, and postoperative support. Useful questions for a cosmetic surgery consultation include: What training and certification do you have? How many times have you carried out this operation? Does my medical history and physical anatomy make me an appropriate candidate? What are the most common complications in your practice? What low-frequency, high-impact risks should I know about? Who will provide anesthesia? What happens if I have a complication after business hours? Which hospital or emergency facility would treat me if a serious problem occurred? What follow-up visits are included? Could I face extra surgeon, facility, anesthesia, medication, or revision fees? 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. 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. When medical language or a possible complication is confusing, the patient should request a clearer explanation. 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. Potential emergency signs after cosmetic surgery include: Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness Unexpected pain, swelling, redness, or heat affecting one leg Uncontrolled bleeding or a sudden increase in swelling Pain that remains severe despite the prescribed treatment plan High fever, chills, spreading redness, or pus-like drainage Disorientation, marked weakness, or excessive drowsiness Skin that becomes very pale, dark, blistered, or cold to the touch An emergency eye symptom such as severe pain, sudden visual change, or vision loss Repeated vomiting or an inability to keep fluids down Any problem your surgeon specifically described as requiring emergency care Emergency medical services should be contacted immediately for potentially life-threatening complications. Patients should seek immediate care rather than waiting for the surgeon's office when serious bleeding, breathing problems, chest pain, fainting, or another critical symptom occurs. Cosmetic Surgery Costs and Canadian Health Coverage Canadian provincial and territorial health plans generally do not pay for operations performed solely for cosmetic reasons. 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. Coverage may depend on the medical service required, the location where treatment is provided, and the patient's provincial or territorial plan. Patients should budget for possible travel, lodging, caregiving, time away from employment, child care, and future revision surgery. Medical tourists need to determine which Canadian provider, if any, will manage recovery and complications after their return. 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. Before deciding, compare what the operation may achieve with its physical, psychological, practical, and economic consequences. 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. Deciding Whether Cosmetic Surgery Is Right for You 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. 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.
