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. Cosmetic surgery may offer benefits, cosmetic plastic surgery near me but no operation is entirely predictable. Understanding the risks of cosmetic surgery is an essential 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. Complications may result from anesthetic medication, bleeding, infection, delayed healing, unexpected reactions, or an individual response to surgery. Some complications are temporary and easy to treat. 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. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits.
Understanding the Risks of Cosmetic Surgery
The risks of cosmetic surgery include unwanted outcomes that affect health, physical function, or appearance. Risk levels vary according to the procedure, surgical method, treatment area, operation length, anesthesia type, and the patient's general 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. A complication extends beyond normal recovery and may need medical care.
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
- Blood clots affecting the legs or lungs
- An incision that heals poorly, slowly, or begins to open
- Visible scarring that may be thick, widened, raised, or irregular
- Nerve-related problems, including numbness or unusual sensation
- Loss of skin, fat, or other tissue because of reduced circulation
- Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials
- Aesthetic concerns such as asymmetry, poor contours, or an unwanted result
- Problems with normal function, including breathing, motion, or sensation
- A need for further care or corrective surgery
Although serious complications are rare, they must still be reviewed before surgery. 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
A degree of discomfort and physical change is expected while the body heals. Patients should understand what is expected so they can tell the difference between routine recovery and a warning sign.
Pain and Tenderness
The amount of pain experienced depends on both the procedure and the individual. 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
Inflammation and the movement of fluid into surgical tissues cause swelling. 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.
Patients are advised to avoid making early judgments about their final appearance. 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. Temporary changes such as tingling, numbness, tenderness, or reduced sensation may occur after surgery. Feeling frequently returns as the nerves heal, although full recovery is not certain. In some cases, changes in sensation may be permanent.
Short-Term Activity Restrictions
Patients may need help with transportation, meals, child care, pet care, household work, and personal tasks. Restrictions may apply to driving, physical activity, lifting, swimming, and work. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored.
Medical and Surgical Risks
Bleeding and Hematoma
A small amount of bleeding may occur around an incision. More significant bleeding can form a hematoma, which is a collection of blood beneath the skin or inside the surgical area. 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. Some hematomas require another operation to control the bleeding and remove collected blood.
Surgical Infection
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.
Treatment may involve antibiotics, wound care, drainage, or another operation. An infected breast implant or other medical device may need to be removed. Patients who smoke or have uncontrolled diabetes, nutritional problems, or poor blood flow may face a higher infection risk and slower recovery.
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.
A minor fluid collection can sometimes disappear as the body reabsorbs it. 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.
Deep Vein Thrombosis and Pulmonary Embolism
A blood clot that forms in a deep vein, commonly within the leg, is called deep vein thrombosis, or DVT. A pulmonary embolism can occur if a piece of the clot breaks away and reaches the lungs. This complication can be life-threatening and must be treated urgently.
Factors that may raise blood clot risk include lengthy surgery, reduced mobility, a history of clots, particular medications, nicotine exposure, obesity, certain illnesses, and multiple procedures performed together. Risk-reduction measures can include early movement, compression devices, supportive garments, adequate fluids, and anticoagulant medication when medically suitable.
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.
Incision problems may need wound care, antibiotics, surgical cleaning, or further corrective surgery. Healing by secondary intention means allowing an open area to close gradually from the inside outward. The recovery period may be extended, and the final scar may be more prominent.
Tissue Necrosis
Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and die. This complication can occur after procedures that lift, tighten, or reposition large sections of tissue. Smoking, vaping, and other nicotine use can greatly increase risk by narrowing blood vessels and reducing tissue oxygen.
Management of necrosis varies according to the size and depth of the affected area. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery.
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:
- Feeling sick or vomiting after anesthesia
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- Headache or sore throat
- An allergic response or adverse drug reaction
- Abnormal blood pressure or irregular heart rhythm
- Breathing difficulties
- Stomach contents entering the lungs, known as aspiration
- Dental, lip, or airway damage
- Serious heart, lung, or neurological complications
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.
Early scars can be firm, raised, reddish, or more deeply coloured before they mature. Over 12 months or longer, scar tissue can gradually fade and soften. How a scar eventually looks is affected by heredity, skin type, wound tension, infection, ultraviolet exposure, aftercare, incision placement, and the operation performed.
Hypertrophic and Keloid Scarring
A hypertrophic scar becomes thick or raised but stays within the original wound. A keloid grows beyond the borders of the incision. A history of hypertrophic scars or keloids, whether personal or familial, should be discussed before an operation.
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
The treated skin may develop colour changes, redness, noticeable blood vessels, dimpling, firmness, or textural differences. 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.
Aesthetic Risks and Unsatisfactory Results
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:
- Ongoing asymmetry
- Visible dents, bulges, or contour differences
- Under-correction or over-correction
- A result that appears unnatural or excessively tight
- A changing contour as postoperative swelling decreases
- An implant that shifts, rotates, or sits incorrectly
- Noticeable scars or scars in an unfavourable location
- A return of looseness or sagging with age and time
- Dissatisfaction despite an acceptable medical result
Before-and-after images, photographs, and computer simulations may help explain possibilities, but they do not promise a matching result. Every patient's tissues, proportions, and recovery process are unique.
Corrective and Revision Surgery
When problems occur or the outcome may benefit from improvement, revision cosmetic surgery can be considered. 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.
Facelift and Neck Lift Risks
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
Potential rhinoplasty complications include long-lasting swelling, bleeding, infection, unevenness, altered smell, contour problems, a hole in the septum, structural collapse, and nasal breathing difficulty. 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. Severe eye pain or a sudden change in vision requires urgent medical assessment.
Possible Breast Procedure Complications
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.
Breast implants bring added long-term considerations. These include capsular contracture, implant rupture, deflation, rippling, movement, rotation, pain, and the need for future monitoring or surgery. Implants are not lifetime devices. Health Canada also provides safety information about uncommon conditions linked with certain breast implants, including breast implant-associated anaplastic large cell lymphoma.
Risks of Liposuction
Possible problems after liposuction include uneven contours, indentations, rippled or loose skin, changes in fluid balance, reduced feeling, seroma, infection, internal damage, fat embolism, and toxicity from lidocaine. High-volume liposuction and treatment of several regions can place greater stress on the body and make recovery more demanding.
Tummy Tuck and Body Lift Risks
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. 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.
Fat Grafting Risks
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. Additional complications include dead fat tissue, cysts, calcification, infection, oil cysts, and fat entering a blood vessel. Fat transfer risks vary according to whether the treatment area is the face, breast, buttocks, or another body region.
Factors That Increase the Risk of Complications
Certain medical conditions and lifestyle habits increase surgical risk. Preoperative preparation may include laboratory testing, medication changes, weight management, stopping nicotine, or obtaining medical clearance.
The likelihood of complications may increase with:
- Exposure to nicotine through smoking, vaping, gum, patches, or other products
- Diabetes with unstable or elevated blood sugar
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A bleeding disorder or history of blood clots
- Obesity, unstable weight, or recent major weight loss or gain
- Sleep apnea
- Immune disorders or reduced immune function
- Inadequate nutrition or serious anemia
- Scar tissue or circulation changes from prior operations or radiation
- Prescription products, non-prescription medicines, or supplements that alter bleeding and healing
- Mental health concerns or unrealistic goals that interfere with informed decision-making
Having a risk factor does not always mean surgery is impossible. The surgeon needs to evaluate the level of risk and decide whether health or lifestyle changes are necessary before treatment.
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. 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. Cosmetic surgery may change a physical feature, but it cannot guarantee confidence, repair a relationship, create career success, or solve broader personal problems.
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.
Intense and persistent concern about perceived physical defects may be a sign of body dysmorphic disorder, a recognized mental health condition. Surgery may not relieve the underlying concern. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation.
Reducing the Chance of Surgical Complications
Although no operation can be made completely risk-free, thorough preparation can improve safety.
- 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.
- 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.
- Attend all follow-up appointments and report unusual symptoms promptly.
- 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.
How to Select a Cosmetic Surgeon in Canada
Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. Patients may verify a physician's licence and registered specialty through the online register maintained by their provincial or territorial regulator.
Another useful question is whether the doctor holds plastic surgery certification from 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 frequently is this specific procedure performed in your practice?
- Am I a suitable candidate based on my health and anatomy?
- What are the most common complications 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?
- What emergency plan is in place if I need urgent medical treatment?
- What follow-up visits are included?
- What costs could arise if I need treatment or revision surgery?
What Informed Consent Should Include
Informed consent involves more than placing a signature on a document. 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. The surgeon should also explain risks that may have particular importance because of the patient's occupation, health, daily activities, or individual goals.
Patients should have enough time to review consent information without being pressured. Ask for clarification when a term or complication is unclear. Patients may benefit from writing down information, attending with someone they trust, and reading the documents again at home.
Postoperative Warning Signs
The surgeon's office should explain which symptoms require attention and copyright the appropriate provider. Contact the clinic promptly when symptoms are unexpected, worsening, or different from the recovery plan.
Urgent warning signs may 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
- Pain that remains severe despite the prescribed treatment plan
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Disorientation, marked weakness, or excessive drowsiness
- A pale, dark, blistered, or unusually cold area of skin
- Loss of sight, intense eye pain, or an abrupt disturbance in vision
- Repeated vomiting or an inability to keep fluids down
- Any symptom the surgical team identified as an emergency
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.
Financial Risks and Health Coverage in Canada
Canadian provincial and territorial health plans generally do not pay for operations performed solely for cosmetic reasons. Patients usually pay for the surgeon, anesthesia, operating facility, implants, garments, prescriptions, testing, and other related expenses.
Complication-related costs should be discussed before surgery. Coverage may depend on the medical service required, the location where treatment is provided, and the patient's provincial or territorial plan. Extra costs may arise from transportation, hotels, private nursing, lost income, family care, and corrective procedures.
Anyone travelling outside Canada for cosmetic surgery should arrange appropriate postoperative care before coming home. A lower initial price may not include management of infection, wound problems, blood clots, implant complications, or revision surgery.
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. A suitable patient recognizes that improvement is possible, but perfection is not.
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 qualified surgeon may advise against a procedure when the risk is too high, the expected benefit is limited, or the patient's goals cannot be achieved safely. Recommending against surgery can be a sign of careful and ethical medical practice.
How to Make an Informed Cosmetic Surgery Decision
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.
A safer decision involves understanding the procedure, identifying individual risk factors, checking the surgeon's qualifications, discussing concerns, and organizing postoperative care. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
