Through cosmetic surgery, patients may change the shape, proportions, or appearance of their face or 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.
A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. Anesthesia, bleeding, infection, healing difficulties, unexpected reactions, and the body's response to an operation can all cause problems. Some complications are temporary and easy to treat. In other cases, a complication can require drugs, hospital care, another operation, or extended monitoring.
In Canada, patients should be clearly informed about expected benefits, important risks, treatment alternatives, recovery needs, and what may happen if they decline surgery. During a careful consultation, patients should be able to consider the facts without being rushed. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits.
What Are the Risks of Cosmetic Surgery?
Any undesirable medical, functional, or cosmetic result connected with an operation may be considered a cosmetic surgery risk. The type and level of risk depend on the procedure, the surgical technique, the area being treated, the length of the operation, the form of anesthesia, and the patient's overall health.
Many cosmetic procedures are followed by mild expected side effects. 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 an unexpected problem that exceeds routine healing and can require treatment.
Potential problems associated with plastic surgery include:
- A hematoma, which is a collection of blood, or other excessive bleeding
- Incision-site or deep-tissue infection
- 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
- Noticeable, raised, widened, or uneven scars
- Nerve injury, numbness, or altered sensation
- Skin, fat, or tissue loss caused by poor blood supply
- Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products
- Unevenness, contour irregularities, or an unsatisfactory 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. Possible rare complications include severe infection, major hemorrhage, organ damage, heart problems, stroke, a blood clot in the lungs, permanent impairment, and death.
Common Early Effects During Cosmetic Surgery Recovery
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.
Soreness After Cosmetic Surgery
Pain levels vary by procedure and patient. Tightness, aching, burning, or tenderness may occur near the surgical area. Pain should usually become easier to manage as healing continues. 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
Swelling develops when inflammation allows fluid to collect in and around the treated area. It may hide the initial surgical result for weeks or months. Small blood vessels can release blood under the skin, creating bruising. Facial procedures, liposuction, breast surgery, and body contouring can all cause visible swelling and bruising.
Patients should not judge the final result too early. 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. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. 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. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Potential Surgical Complications
Bleeding and Hematoma
Minor bleeding near a surgical incision can occur during early recovery. 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.
A small hematoma may only need monitoring, but a larger one may require drainage. In certain cases, the patient may need to return to the operating room.
Infection After Cosmetic Surgery
Infection may affect the skin, surgical cut, deeper tissue, or the area surrounding an implant. Warning signs can include spreading redness, heat, swelling, worsening pain, pus-like fluid, fever, chills, or an unusual odour.
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.
Fluid Buildup or Seroma
A seroma develops when a pocket of clear fluid forms under the surgical tissues. 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.
Small seromas may resolve as the body absorbs the fluid. 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 Clots and Pulmonary Embolism
Deep vein thrombosis, or DVT, occurs when a blood clot forms in a deep vein, often in the leg. If part of the clot travels to the lungs, it can cause a pulmonary embolism. 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. Depending on the patient, preventive steps may involve getting up early, using compression equipment or garments, staying hydrated, or taking prescribed blood thinners.
Delayed or Difficult 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.
Treatment for a wound complication can include specialized dressings, antibiotic medication, removal of unhealthy tissue, or another operation. 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 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 and nicotine use are major preventable risk factors because nicotine narrows blood vessels and reduces oxygen delivery.
The extent of tissue damage determines which treatment is required. Possible treatment includes wound management, removal of dead tissue, a skin graft, reconstructive surgery, or revision at a later date.
Anesthesia Risks in Cosmetic Surgery
Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. Choosing an anesthesia method requires consideration of the operation, medical background, expected surgical time, and facility.
Possible anesthesia-related problems include:
- Nausea and vomiting
- Light-headedness, confusion, or extended sleepiness
- Throat discomfort or headache
- Allergic or medication reactions
- Abnormal blood pressure or irregular heart rhythm
- Breathing difficulties
- Aspiration, which occurs when material from the stomach reaches the lungs
- Injury to the teeth, lips, mouth, or airway
- Severe cardiac, respiratory, or neurological problems
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.
Cosmetic Surgery Scars and Skin Changes
Whenever an incision is made through the skin, a scar will form. 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. They may soften and fade over 12 months or longer. Genetic factors, skin characteristics, pressure on the incision, infection, sunlight, wound care, surgical location, and procedure type all influence the finished scar.
Hypertrophic Scars and Keloids
A hypertrophic scar becomes thick or raised but stays within the original wound. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. 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. Scar treatment may improve texture and appearance, but it cannot ensure that a hypertrophic scar or keloid will never come back.
Pigment and Texture Irregularities
Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. Alterations in colour or texture may improve, but they can also remain long term. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
Cosmetic Outcome Risks and Patient Dissatisfaction
Even when surgery is performed correctly, the final appearance may not match the patient's expectations. Individual anatomy, skin flexibility, age, past procedures, scarring, and natural asymmetry all affect healing.
Appearance-related problems may include:
- Ongoing asymmetry
- Uneven contours or visible irregularities
- Too little or too much correction
- An artificial-looking or over-tightened outcome
- Alterations in shape while swelling resolves
- Movement or poor positioning of an implant
- Scarring that is prominent or difficult to conceal
- 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. Anatomy and healing responses vary from one person to another.
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.
It is important to ask how the practice handles revisions and which expenses are covered. Additional costs for the surgeon, operating room, anesthetic, implants, medicine, transportation, accommodation, and missed employment may fall outside the initial price.
Risks Associated With Specific Cosmetic Procedures
General surgical risks apply to many operations, but each procedure also has unique concerns.
Facelift and Neck Lift Risks
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. Because nicotine restricts circulation, its use can greatly increase wound and skin-healing complications.
Rhinoplasty Risks
After nose surgery, patients may experience persistent swelling, nosebleeds, infection, asymmetry, smell changes, irregular contours, septal perforation, collapse of nasal support, or obstructed breathing. A rhinoplasty result may not fully settle for 12 months or more. A revision nose operation is often more challenging because the first surgery changes the cartilage and creates internal scarring.
Possible Complications of Eyelid Surgery
After blepharoplasty, patients may develop dry eyes, irritation, blurred vision, trouble shutting the eyelids, lid malposition, asymmetry, scarring, orbital bleeding, or changes in eyesight. Immediate medical evaluation is needed for intense eye pain or a sudden visual disturbance.
Breast Surgery Risks
Nipple sensation, symmetry, scars, and the ability to breastfeed may be affected by breast augmentation, breast lift surgery, or breast reduction. Hematoma, infection, fat necrosis, poor healing, and altered nipple or areola position are also possible.
Implant-based breast surgery involves long-term risks beyond the normal surgical recovery period. 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.
Risks of Liposuction
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.
Possible Tummy Tuck and Body Lift Complications
Tummy tuck and body lift procedures require long incisions and repositioning of broad tissue areas. Seroma, blood clots, infection, necrosis, delayed wound healing, numbness, noticeable scars, and altered belly button position may occur. Recovery may involve several weeks of limited movement and physical activity.
Risks of Fat Transfer
During fat grafting, fat is taken from one body area and placed into a different location. Because a portion of the injected fat may not survive, the final fullness and balance can change. 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 Has a Higher Risk of Complications?
Some health and lifestyle factors can raise the chance of complications. Before proceeding, some patients require tests, adjustments to treatment, weight changes, nicotine cessation, or approval from another medical professional.
Factors associated with higher surgical risk include:
- Exposure to nicotine through smoking, vaping, gum, patches, or other products
- Poorly controlled diabetes
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- Past DVT, pulmonary embolism, or a diagnosed bleeding disorder
- Obesity, unstable weight, or recent major weight loss or gain
- Obstructive sleep apnea
- Immune system disorders
- Inadequate nutrition or serious anemia
- 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
Having a risk factor does not always mean surgery is impossible. Instead, the surgeon must assess whether surgery is reasonably safe and determine cosmetic surgery options 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.
The patient's motivation for considering surgery should be discussed during an appropriate assessment. 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 is a mental health condition involving intense distress about perceived appearance flaws. 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
Risk cannot be removed completely, but careful planning can make cosmetic surgery safer.
- Work with a properly trained physician whose practice includes the cosmetic operation you are considering.
- 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.
- Disclose your entire health history, including previous surgery, allergies, medications, supplements, alcohol, cannabis, and nicotine use.
- 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.
- 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.
- Wait until healing is mature before deciding whether revision surgery is needed.
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.
Canadian patients can ask if their surgeon has been certified in plastic surgery by the Royal College of Physicians and Surgeons of Canada. Certification is one useful qualification to review, but patients should also consider experience with the specific procedure, complication management, communication, surgical setting, and follow-up care.
During the consultation, patients may wish to ask:
- What are your surgical qualifications and specialty credentials?
- How many times have you carried out this operation?
- Does my medical history and physical anatomy make me an appropriate candidate?
- What complications are seen most frequently with this procedure in your practice?
- What low-frequency, high-impact risks should I know about?
- Who is responsible for anesthesia care during the operation?
- Who should I contact if I experience a complication outside normal clinic hours?
- Where would I receive emergency care if needed?
- How many postoperative appointments are provided as part of the surgical plan?
- What costs could arise if I need treatment or revision surgery?
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.
A proper consent discussion includes the procedure itself, expected improvement, significant complications, alternative options, recovery requirements, limitations, and the choice to decline treatment. Any complication that could significantly affect the patient's medical condition, employment, lifestyle, or priorities should receive special attention.
No one should be pushed into signing a surgical consent form quickly. Questions should be asked whenever risks, terminology, or instructions are not fully understood. Taking notes, involving a support person, and reviewing written material outside the clinic can support an informed decision.
Postoperative Warning Signs
Patients should receive clear directions about warning signs, emergency care, and after-hours communication. 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
- Heavy bleeding or rapidly increasing swelling
- Intense pain that does not improve after taking the recommended medicine
- High fever, chills, spreading redness, or pus-like drainage
- Confusion, extreme weakness, or difficulty staying awake
- Possible tissue damage shown by abnormal colour, blistering, or low skin temperature
- An emergency eye symptom such as severe pain, sudden visual change, or vision loss
- Repeated vomiting or an inability to keep fluids down
- A symptom listed as urgent in the postoperative instructions
Call 911 or seek emergency care when symptoms may be life-threatening. 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.
Cosmetic Surgery Costs and Canadian Health Coverage
Procedures performed only to change appearance are generally not covered by provincial or territorial health insurance. Out-of-pocket expenses may include the surgeon, anesthesia provider, operating room, medical devices, recovery clothing, prescriptions, laboratory work, and follow-up items.
Complication-related costs should be discussed before surgery. Whether care is publicly covered can depend on the treatment needed, where it is delivered, and the rules of the patient's province or territory. 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
Patients should consider surgery only when their goals are achievable, their health is suitable, and they understand the risks and recovery. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection.
Take time to compare the expected benefit with the medical, emotional, practical, and financial risks. The decision should account for recovery restrictions, permanent scarring, employment absence, and the possibility that the final result may fall short of expectations.
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.
Deciding Whether Cosmetic Surgery Is Right for You
Being aware of possible complications is not the same as believing they are certain to happen. The goal is to make a careful choice based on medical information, not promotional claims, social media influence, or the lowest price.
Before surgery, research the operation, assess your health risks, verify medical credentials, ask thorough questions, and prepare for the complete healing period. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
