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. Understanding the risks of cosmetic surgery is an important part of deciding whether a procedure is right for you.
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. More serious problems may call for medication, hospital treatment, revision surgery, or ongoing medical follow-up.
Patients in Canada should receive clear information about the expected benefits, material risks, alternatives, recovery requirements, and possible consequences of not having treatment. A thorough consultation should provide enough time to review the information and make a decision without pressure. Cosmetic surgery is usually elective, so you should feel comfortable delaying or declining it when the risks outweigh the likely benefits.
What Are the Risks of Cosmetic Surgery?
Cosmetic surgery risks include any unwanted medical, functional, or aesthetic outcome linked to an operation. 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.
It is normal for patients to experience some minor effects after many operations. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. A complication is different. 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
- An infection in the incision or deeper surgical tissues
- A collection of fluid called a seroma
- Blood clots affecting the legs or lungs
- Delayed wound healing or wound separation
- Visible scarring that may be thick, widened, raised, or irregular
- 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
- Asymmetry, contour problems, or an unwanted appearance
- Functional changes affecting breathing, movement, or feeling
- A need for further care or corrective 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
A degree of discomfort and physical change is expected while the body heals. Patients who understand expected recovery are better able to separate routine symptoms from possible complications.
Soreness After Cosmetic Surgery
Each patient experiences pain differently, and some operations cause more discomfort than others. Tightness, aching, burning, or tenderness may occur near the surgical area. As recovery progresses, pain should generally become less intense and easier to control. 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
Inflammation and the movement of fluid into surgical tissues cause swelling. For several weeks or even months, swelling may conceal the true result of surgery. 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.
Patients are advised to avoid making early judgments about their final appearance. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Altered Sensation and Numbness
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. Feeling frequently returns as the nerves heal, although full recovery is not certain. There is a possibility that altered feeling will not fully resolve.
Activity Limitations During Recovery
Patients may need help with transportation, meals, child care, pet care, household work, and personal tasks. Driving, exercise, heavy lifting, swimming, and returning to work may be restricted. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Potential Surgical Complications
Postoperative 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. 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.
Surgical Infection
The incision, nearby skin, deeper surgical tissues, or an implant pocket can become infected. 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. 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. 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. If fluid is not treated, it may strain the incision, delay healing, or lead to infection.
Blood Clot Complications
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 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
A surgical wound may take longer than expected to close or may start to open. Reduced blood supply, infection, tension on the wound, nicotine exposure, certain medications, and medical conditions can interfere with healing.
Wound problems may require dressings, antibiotics, removal of damaged tissue, or additional surgery. Healing by secondary intention means allowing an open area to close gradually from the inside outward. This process can take longer and may leave a more visible scar.
Loss of Tissue From Poor Blood Supply
When skin, fat, or other tissue loses its blood supply and starts to die, the condition is called necrosis. Tissue loss may occur after procedures involving extensive lifting, tightening, or repositioning. Nicotine exposure is an important avoidable risk because it constricts blood vessels and limits oxygen reaching the tissues.
Management of necrosis varies according to the size and depth of the affected area. Possible treatment includes wound management, removal of dead tissue, a skin graft, reconstructive surgery, or revision at a later date.
Risks Related to Anesthesia
Depending on the operation, cosmetic surgery can involve local anesthetic, sedating medication, general anesthesia, or multiple methods together. The most suitable anesthesia plan is based on the type of surgery, patient health history, procedure duration, and location where surgery takes place.
Anesthesia may be associated with the following risks:
- Nausea and vomiting
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- A headache or irritation of the throat
- Allergic or medication reactions
- Fluctuations in blood pressure or disturbances in heartbeat
- Problems with breathing
- Aspiration, which occurs when material from the stomach reaches the lungs
- Injury to the teeth, lips, mouth, or airway
- Major complications involving the heart, lungs, or nervous system
Patients must provide complete information about prescriptions, non-prescription drugs, vitamins, supplements, cannabis, alcohol, nicotine, allergies, earlier anesthesia problems, and medical conditions before surgery. Withholding medical or lifestyle information may increase the risks of anesthesia and surgery.
Cosmetic Surgery Scars and Skin Changes
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.
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. The final appearance depends on genetics, skin type, incision tension, infection, sun exposure, wound care, location, and the type of operation.
Hypertrophic and Keloid Scarring
Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. A keloid grows beyond the borders of the incision. Patients should inform their surgeon if they or close family members have developed raised or unusual scars.
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.
Pigment and Texture Irregularities
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. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
The Risk of an Unwanted Cosmetic Result
Even when surgery is performed correctly, the final appearance may not match the patient's expectations. The body's response is shaped by age, anatomy, skin quality, earlier surgery, scar development, and normal side-to-side differences.
Appearance-related problems may include:
- Persistent asymmetry
- Visible dents, bulges, or contour differences
- Under-correction or over-correction
- An artificial-looking or over-tightened outcome
- A changing contour as postoperative swelling decreases
- 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
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.
Corrective and Revision Surgery
Revision surgery may be considered when a complication occurs or when the result can be improved. However, another operation brings new 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.
It is important to ask how the practice handles revisions and which expenses are covered. Surgeon fees, facility costs, anesthesia, implants, medications, travel, and time away from work may not all be included in the original price.
Procedure-Specific Cosmetic Surgery Risks
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Possible Facelift and Neck Lift Complications
Possible problems after a facelift or neck lift include bleeding beneath the skin, nerve damage, changes to the hairline, localized hair loss, tissue loss, uneven contours, altered earlobes, numbness, facial weakness, and noticeable scars. Nicotine use can greatly increase the risk of skin-healing problems.
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. Scar formation and altered cartilage can make secondary rhinoplasty more complex.
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
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. Patients should not assume that breast implants will remain in place permanently without further care. Patients in Canada can review Health Canada information about uncommon implant-related conditions, such as breast implant-associated anaplastic large cell lymphoma.
Risks of Liposuction
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. Removing larger volumes of fat or treating several body areas may increase medical stress and recovery demands.
Possible Tummy Tuck and Body Lift Complications
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. Patients may need several weeks of movement restrictions.
Risks of Fat Transfer
Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. Some of the transferred fat will be absorbed, which can affect volume and symmetry. Additional complications include dead fat tissue, cysts, calcification, infection, oil cysts, and fat entering a blood vessel. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area.
Factors That Increase the Risk of Complications
Certain medical conditions and lifestyle habits increase surgical risk. Before proceeding, some patients require tests, adjustments to treatment, weight changes, nicotine cessation, or approval from another medical professional.
Risk factors may include:
- Exposure to nicotine through smoking, vaping, gum, patches, or other products
- Poorly controlled diabetes
- Heart, lung, kidney, liver, or blood vessel disease
- Past DVT, pulmonary embolism, or a diagnosed bleeding disorder
- A high body mass index or significant changes in weight
- Sleep apnea
- Conditions affecting the immune system
- Inadequate nutrition or serious anemia
- Previous radiation or surgery in the treatment area
- Prescription products, non-prescription medicines, or supplements that alter bleeding and healing
- Expectations that cannot be achieved or unaddressed psychological concerns affecting consent
The presence of one or more risk factors does not automatically prevent cosmetic surgery. Instead, the surgeon must assess whether surgery is reasonably safe and determine what preparation is required.
Emotional and Mental Health Considerations
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. A short period of sadness or emotional difficulty after surgery is sometimes known as postoperative blues.
More serious dissatisfaction can occur when expectations do not match what surgery can realistically achieve. 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. Warning signs may include pressure from another person, repeated procedures without satisfaction, extreme focus on a minor feature, or the belief that one operation will completely transform a person's 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.
Ways to Lower Cosmetic Surgery Risks
Cosmetic surgery always carries some risk, yet careful planning can reduce the likelihood of complications.
- Select a qualified doctor who has appropriate education and substantial experience performing 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.
- Give the surgical team accurate information about diagnoses, operations, prescriptions, supplements, substances, and allergies.
- Follow instructions about fasting, medication changes, testing, and stopping nicotine.
- Arrange a responsible adult to drive you home and assist during early recovery when required.
- Review the expected healing schedule before arranging employment, trips, strenuous activity, or important occasions.
- Attend all follow-up appointments and report unusual symptoms promptly.
- Your recovery should not be compared with social media images, promotional content, or another person's timeline.
- Wait until healing is mature before deciding whether revision surgery is needed.
Choosing a Cosmetic Surgeon in Canada
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.
Another useful question is whether the doctor holds plastic surgery certification from the Royal College of Physicians and Surgeons of Canada. While certification matters, patients should also assess procedure-specific experience, communication, the quality of the facility, aftercare, and the surgeon's approach to complications.
During the consultation, patients may wish to ask:
- What training and certification do you have?
- How frequently is this specific procedure performed in your practice?
- Based on my health, goals, and anatomy, is this procedure suitable for me?
- 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?
- What happens if I have a complication after business hours?
- Where would I receive emergency care if needed?
- How many postoperative appointments are provided as part of the surgical plan?
- Which additional expenses would I be responsible for if a complication or revision occurs?
Informed Consent for Cosmetic Surgery
Signing paperwork alone does not create true informed consent. The process requires clear communication so that the patient can make a knowledgeable and voluntary choice.
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
Patients should receive clear directions about warning signs, emergency care, and after-hours communication. The surgical team should be contacted quickly if symptoms become worse, appear unusual, or do not match the expected healing process.
Symptoms that may require urgent care include:
- Chest pain, shortness of breath, coughing blood, or fainting
- Sudden swelling, pain, redness, or warmth in 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
- Mental confusion, severe weakness, or unusual inability to remain alert
- Skin that becomes very pale, dark, blistered, or cold to the touch
- Sudden vision loss, severe eye pain, or major visual changes
- Persistent vomiting that prevents normal hydration
- Any symptom the surgical team identified as an emergency
When a symptom could represent a life-threatening emergency, call 911 or go to an emergency department. 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.
Financial Considerations for Cosmetic Surgery in Canada
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. 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. 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. A suitable patient recognizes that improvement is possible, but perfection is not.
Before deciding, compare what the operation may achieve with its physical, psychological, practical, and economic consequences. 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. 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 cosmetic procedures 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.
