The shape, proportion, or overall appearance of the face and body can be improved through cosmetic surgery. A person may also feel more at ease with a long-standing appearance concern after cosmetic surgery. Even so, all operations involve some uncertainty. A careful decision about cosmetic surgery should include a clear understanding of its possible risks.
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.
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. Most cosmetic procedures are optional, which means you can delay or decline surgery when its risks do not justify its likely benefits.
Understanding the Risks of Cosmetic Surgery
The risks of cosmetic surgery include unwanted outcomes that affect health, physical function, or appearance. The procedure being performed, technique used, body area treated, duration of surgery, anesthesia method, and patient health all influence risk.
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.
Possible complications of plastic surgery include:
- Bleeding or a collection of blood called a hematoma
- An infection in the incision or deeper surgical tissues
- Seroma formation, which involves fluid collecting beneath the tissue
- Blood clots in the legs or lungs
- An incision that heals poorly, slowly, or begins to open
- Scars that become prominent, raised, wide, or uneven
- 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
- Unevenness, contour irregularities, or an unsatisfactory appearance
- Changes in function, such as breathing, movement, or sensation
- The need for additional treatment or revision 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.
Common Short-Term Effects After Cosmetic Surgery
Some discomfort and physical change are part of normal healing. Patients who understand expected recovery are better able to separate routine symptoms from possible complications.
Postoperative Pain and Tenderness
Pain levels vary by procedure and patient. The surgical site can feel tender, tight, sore, or mildly burning during recovery. 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.
Postoperative Swelling and Bruising
Swelling develops when inflammation allows fluid to collect in and around the treated area. 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 should not judge the final result too early. Remaining swelling may temporarily affect shape, balance, and the texture of the skin.
Numbness and Changes in Sensation
Small sensory nerves may be stretched, moved, or cut during surgery. Some procedures commonly cause short-term numbness, tingling, increased sensitivity, or a decrease in feeling. Feeling frequently returns as the nerves heal, although full recovery is not certain. There is a possibility that altered feeling will not fully resolve.
Temporary Limits on Activity
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. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Surgical and Medical Complications
Bleeding or Blood Collection
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. Possible signs of a hematoma include worsening pain, hard swelling, colour changes, or sudden asymmetry.
Depending on its size and symptoms, a hematoma may be watched or medically drained. A return to the operating room may be necessary in more serious cases.
Surgical 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.
Treatment may involve antibiotics, wound care, drainage, or another operation. If a breast implant or another implanted device becomes infected, removal may be necessary. Infection risk and treatment difficulty may increase with smoking, poorly controlled diabetes, inadequate nutrition, or reduced circulation.
Postoperative Seroma
Clear fluid that gathers beneath the skin is known as a seroma. 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.
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
Deep vein thrombosis, known as DVT, develops when a clot forms in one of the body's deep veins, usually in a leg. If part of the clot travels to the lungs, it can cause a pulmonary embolism. This is a medical emergency.
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. 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. Healing may be impaired by poor circulation, infection, pressure on the incision, nicotine, some medicines, or underlying health conditions.
Treatment for a wound complication can include specialized dressings, antibiotic medication, removal of unhealthy tissue, or another operation. When a wound is left to close slowly from its deeper layers toward the surface, the process is called healing by secondary intention. This process can take longer and may leave a more visible scar.
Skin or Tissue Necrosis
Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to die. Operations that move, tighten, or lift broad areas of tissue can carry a risk of necrosis. Smoking and nicotine use are major preventable risk factors because nicotine narrows blood vessels and reduces oxygen delivery.
Treatment depends on the amount of tissue affected. It may involve wound care, removal of damaged tissue, skin grafting, reconstructive surgery, or a delayed revision.
Risks Related to Anesthesia
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
- Dizziness, confusion, or prolonged drowsiness
- Headache or sore throat
- Allergic or medication reactions
- Abnormal blood pressure or irregular heart rhythm
- Respiratory difficulty
- Aspiration of stomach contents into 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.
Changes in Scarring, Colour, and Skin Texture
Any procedure that cuts the skin creates a scar. A surgeon may try to conceal incisions in folds, hair-bearing areas, or covered locations, but complete scar elimination is not possible.
During the first stages of healing, scars may look red, thick, firm, elevated, or darker than nearby skin. They may soften and fade over 12 months or longer. 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
A scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. Keloid tissue spreads past the edges of the initial incision. People with a personal or family history of abnormal scarring should tell their surgeon before surgery.
Treatment options can include silicone sheets or gels, pressure treatment, corticocopyright injections, laser therapy, and 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. Alterations in colour or texture may improve, but they can also remain long term. The risk can differ by skin tone and by the type of procedure performed.
Cosmetic Outcome Risks and Patient Dissatisfaction
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.
Possible aesthetic concerns include:
- Unevenness that remains after healing
- Irregular or uneven body contours
- Under-correction or over-correction
- A result that appears unnatural or excessively tight
- Changes in shape as swelling settles
- Movement or poor positioning of an implant
- Scarring that is prominent or difficult to conceal
- A return of looseness or sagging with age and time
- Dissatisfaction despite an acceptable medical result
Visual examples and digital imaging can guide consultation discussions, although no patient can be guaranteed the same outcome. Each patient has different anatomy and heals in a different way.
The Possibility of Revision Surgery
A corrective operation may be discussed if a complication develops or if the original result could be refined. A second procedure introduces another set of surgical risks. Because scarred tissues may be less flexible and have reduced circulation, revision procedures can be more difficult.
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.
Complications by Type of Cosmetic Surgery
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Risks of Facelift and Neck Lift Surgery
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. Nicotine use can greatly increase the risk of skin-healing problems.
Possible Rhinoplasty Complications
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. Scar formation and altered cartilage can make secondary rhinoplasty more complex.
Eyelid Surgery Risks
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. A patient should seek urgent care if severe eye pain or an abrupt change in vision occurs.
Possible Breast Procedure Complications
Breast augmentation, breast lift, and breast reduction may affect nipple sensation, breast symmetry, scar appearance, and the ability to breastfeed. 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. 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.
Liposuction Risks
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. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated.
Risks of Abdominoplasty and Body Lift Surgery
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
Fat transfer involves removing fat from one area and injecting it into another. 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. The location where fat is injected, such as the face, breasts, or buttocks, affects the type and seriousness of potential complications.
Who Has a Higher Risk of Complications?
Some health and lifestyle factors can raise the chance of complications. A patient may need medical testing, treatment changes, weight management, nicotine cessation, or clearance from another health professional before surgery.
Factors associated with higher surgical risk include:
- Cigarette smoking, vaping, or any form of nicotine use
- Diabetes that is not well controlled
- Cardiac, respiratory, renal, liver, or vascular conditions
- A bleeding disorder or history of blood clots
- Obesity or major weight changes
- Sleep apnea
- Conditions affecting the immune system
- Poor nutrition or significant anemia
- 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
A higher-risk medical history does not necessarily make an operation unsuitable. Instead, the surgeon must assess whether surgery is reasonably safe and determine what preparation is required.
Emotional and Mental Health Considerations
Cosmetic surgery can affect emotional health as well as physical health. During recovery, patients can become anxious or discouraged because they look swollen, feel tired, and cannot resume normal activities. This temporary low mood is sometimes called postoperative blues.
Significant dissatisfaction is more likely when the expected transformation is not medically achievable. A cosmetic procedure can modify the body, but it does not guarantee emotional confidence, relationship improvement, career advancement, or solutions to unrelated personal concerns.
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 is a mental health condition involving intense distress about perceived appearance flaws. An operation may fail to resolve the deeper psychological distress. 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.
- Choose a properly qualified physician with training and experience relevant to 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.
- Provide a complete medical history, including medications, supplements, nicotine, cannabis, alcohol, allergies, and prior operations.
- Follow instructions about fasting, medication changes, testing, and stopping nicotine.
- Plan for a trusted adult to take you home and help with daily needs after surgery.
- 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.
- Your recovery should not be compared with social media images, promotional content, or another person's timeline.
- Allow swelling and scar tissue to settle fully before considering corrective surgery.
Choosing a Cosmetic Surgeon in Canada
Medical regulation in Canada is handled at the provincial and territorial level. 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. 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.
Questions to ask during a cosmetic surgery consultation include:
- What are your surgical qualifications and specialty credentials?
- How many times have you carried out this operation?
- Based on my health, goals, and anatomy, is this procedure suitable for me?
- What are the most common complications in your practice?
- Which uncommon but severe complications need to be considered?
- Which medical professional will administer and monitor my anesthesia?
- 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?
- Which additional expenses would I be responsible for if a complication or revision occurs?
Understanding Informed Consent
Informed consent is more than signing a form. It is an ongoing discussion that should give the patient enough information to make a voluntary decision.
Patients should be informed about how the operation works, its likely benefits, material risks, alternatives, healing process, limits, and the possible consequences of no surgery. Risks that are especially relevant to the patient's health, job, lifestyle, or personal priorities should also be discussed.
A patient should never feel rushed to sign. 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. Unexpected or worsening symptoms that fall outside the recovery instructions should be reported without delay.
Symptoms that may require urgent care include:
- Pain in the chest, difficulty breathing, coughing up blood, or loss of consciousness
- Sudden swelling, pain, redness, or warmth in one leg
- Significant bleeding or swelling that expands quickly
- 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
- 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
- Persistent vomiting that prevents normal hydration
- Any problem your surgeon specifically described as requiring emergency care
When a symptom could represent a life-threatening emergency, call 911 or go to an emergency department. 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 Considerations for Cosmetic Surgery in Canada
Procedures performed only to change appearance are generally not covered by provincial or territorial health insurance. The patient is normally responsible for surgeon fees, anesthetic services, facility charges, implants, compression garments, medication, tests, and associated costs.
Before an operation, patients should ask who pays for treatment if a complication develops. 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. 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. Realistic patients seek meaningful improvement while accepting that no procedure can deliver a flawless result.
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
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 top cosmetic plastic surgery 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. When the benefits, limits, alternatives, and possible complications are understood, patients are better prepared to decide whether cosmetic surgery fits their needs.
