Through cosmetic surgery, patients may refine the shape, proportions, or appearance of their face or body. 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.
Although most patients heal without serious problems, no surgeon can guarantee perfection or eliminate every surgical risk. Problems can occur because of anesthesia, bleeding, infection, poor healing, an unexpected reaction, or the way the body responds to surgery. Some complications are temporary and easy to treat. More serious problems may call for medication, hospital treatment, revision surgery, or ongoing medical follow-up.
In Canada, patients should be clearly informed about expected benefits, important risks, treatment alternatives, recovery needs, and what may happen if they decline surgery. A thorough consultation should provide enough time to review the information and make a decision without pressure. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits.
What Are the Risks of Cosmetic Surgery?
Cosmetic surgery risks include any unwanted medical, functional, or aesthetic outcome linked to an operation. 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 true complication is not the same as an expected side effect. It is an unexpected problem that exceeds routine healing and can require treatment.
Possible complications of plastic surgery include:
- Bleeding or a collection of blood called a hematoma
- Infection at the incision or within deeper tissue
- A collection of fluid called a seroma
- Clots that form in a leg vein or travel to the lungs
- Slow wound healing or separation of the incision
- Noticeable, raised, widened, or uneven scars
- Nerve injury, numbness, or altered sensation
- Loss of skin, fat, or other tissue because of reduced circulation
- Reactions to anesthesia, medications, adhesives, or surgical materials
- Aesthetic concerns such as asymmetry, poor contours, or an unwanted result
- 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. Uncommon but severe risks can include serious infection, substantial bleeding, damage to an organ, cardiac complications, stroke, pulmonary embolism, lasting disability, or death.
Common Early Effects During Cosmetic Surgery Recovery
Normal recovery often includes temporary discomfort and changes in appearance or sensation. Patients who understand expected recovery are better able to separate routine symptoms from possible complications.
Pain and Tenderness
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.
Bruising and Tissue Swelling
Swelling is caused by inflammation and fluid moving into the treated tissues. It may hide the initial surgical result for weeks or months. Bruising occurs when small blood vessels leak beneath the skin. Visible bruising and swelling may follow facial surgery, liposuction, breast procedures, or body contouring.
The outcome of surgery should not be assessed before healing has progressed. Remaining swelling may temporarily affect shape, balance, and the texture of the skin.
Changes in Feeling After Surgery
During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. Temporary numbness, tingling, sensitivity, or reduced feeling is common after some operations. Nerve recovery often improves sensation over time, but normal feeling may not return completely. Permanent sensory changes are possible.
Temporary Limits on Activity
During early recovery, patients may require support with transportation, meals, family duties, pets, household chores, and self-care. Driving, exercise, heavy lifting, swimming, and returning to work may be restricted. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Surgical and Medical Complications
Bleeding and Hematoma
Minor bleeding near a surgical incision can occur during early recovery. 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.
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
The incision, nearby skin, deeper surgical tissues, or an implant pocket can become infected. 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
A seroma develops when a pocket of clear fluid forms under the surgical tissues. Procedures such as abdominoplasty, body lift surgery, breast surgery, and large-area liposuction may have a greater seroma risk because they create space beneath the tissue.
A minor fluid collection can sometimes disappear as the body reabsorbs it. Larger ones may need to be drained, sometimes more than once. Untreated fluid can place pressure on the incision, affect healing, or become infected.
Deep Vein Thrombosis and Pulmonary Embolism
Deep vein thrombosis, or DVT, occurs when a blood clot forms in a deep vein, often in the leg. When part of a deep vein clot moves into the lungs, it may block blood flow and cause a pulmonary embolism. 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. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate.
Poor Wound Healing
An incision may heal slowly or begin to separate. 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.
Tissue Necrosis
Necrosis occurs when inadequate circulation causes living tissue, such as skin or fat, to become damaged and die. Tissue loss may occur after procedures involving extensive lifting, tightening, or repositioning. Smoking, vaping, and other nicotine use can greatly increase risk by narrowing blood vessels and reducing tissue oxygen.
Treatment depends on the amount of tissue affected. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery.
Potential Complications of Anesthesia
Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. 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:
- Feeling sick or vomiting after anesthesia
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- A headache or irritation of the throat
- An allergic response or adverse drug reaction
- Changes in blood pressure or heart rhythm
- Respiratory difficulty
- Stomach contents entering the lungs, known as aspiration
- Dental, lip, or airway damage
- Major complications involving the heart, lungs, or nervous system
A preoperative health history should include every medication, vitamin, supplement, cannabis product, alcohol or nicotine habit, allergy, previous anesthetic reaction, and relevant diagnosis. Withholding medical or lifestyle information may increase the risks of anesthesia and surgery.
Changes in Scarring, Colour, and Skin Texture
Any procedure that cuts the skin creates a scar. Surgeons usually place incisions where they can be hidden within natural folds, hairlines, or clothing, but a scar cannot be erased completely.
Early scars can be firm, raised, reddish, or more deeply coloured before they mature. Scars may require a year or more to flatten, soften, and become less noticeable. 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 scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. A keloid grows beyond the borders of the incision. People with a personal or family history of abnormal scarring should tell their surgeon before surgery.
Possible treatments include silicone products, pressure therapy, copyright injections, laser treatment, or scar revision. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return.
Pigment and Texture Irregularities
The treated skin may develop colour changes, redness, noticeable blood vessels, dimpling, firmness, or textural differences. Some of these changes resolve over time, while others can last permanently. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
The Risk of an Unwanted Cosmetic Result
A procedure can be medically and technically successful while still producing a result the patient did not anticipate. Healing is affected by anatomy, skin elasticity, cosmetic plastic surgery treatments age, previous surgery, scar formation, and natural differences between the two sides of the body.
Possible aesthetic concerns include:
- Persistent asymmetry
- Visible dents, bulges, or contour differences
- Too little or too much correction
- A result that appears unnatural or excessively tight
- A changing contour as postoperative swelling decreases
- Movement or poor positioning of an implant
- Noticeable scars or scars in an unfavourable location
- Recurrence of sagging or tissue laxity over time
- Disappointment with an outcome that falls within an acceptable surgical range
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.
Revision Cosmetic Surgery
When problems occur or the outcome may benefit from improvement, revision cosmetic surgery can be considered. A second procedure introduces another set of surgical risks. 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.
Complications by Type of Cosmetic Surgery
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. Smoking, vaping, and other nicotine exposure can significantly raise the chance of skin loss and delayed healing.
Possible Rhinoplasty Complications
Rhinoplasty may cause ongoing swelling, nosebleeds, infection, asymmetry, changes in smell, visible contour irregularities, septal perforation, nasal collapse, or difficulty breathing through the nose. It can take at least a year for swelling to resolve enough for the final nasal shape to be assessed. Revision rhinoplasty can be more difficult because of scar tissue and changes to the cartilage.
Blepharoplasty 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. Severe eye pain or a sudden change in vision requires urgent medical assessment.
Risks of Cosmetic Breast Surgery
Procedures such as breast augmentation, mastopexy, and breast reduction can change nipple feeling, breast balance, scarring, and future breastfeeding ability. Other risks include hematoma, infection, fat necrosis, delayed healing, and changes in nipple or areola position.
Implant-based breast surgery involves long-term risks beyond the normal surgical recovery period. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. Implants are not lifetime devices. Health Canada publishes safety guidance concerning rare illnesses associated with some breast implants, including breast implant-associated anaplastic large cell lymphoma.
Liposuction Risks
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. High-volume liposuction and treatment of several regions can place greater stress on the body and make recovery more demanding.
Risks of Abdominoplasty and Body Lift Surgery
Large sections of skin and underlying tissue are moved during abdominoplasty and body lift surgery. Risks include seroma, blood clots, infection, skin loss, wound separation, numbness, prominent scarring, and changes to the position or shape of the belly button. Activity and lifting restrictions can remain in place for a number of weeks.
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. Other risks include fat necrosis, cysts, calcification, infection, oil cysts, and accidental injection into a blood vessel. 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?
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
- Diabetes that is not well controlled
- Cardiac, respiratory, renal, liver, or vascular conditions
- Past DVT, pulmonary embolism, or a diagnosed bleeding disorder
- Obesity or major weight changes
- A diagnosed or suspected sleep-related breathing disorder
- Immune system disorders
- Poor nutrition or significant anemia
- Earlier surgery or radiation therapy involving the same area
- Medications or supplements that affect bleeding or healing
- 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 what preparation is required.
Emotional and Mental Health Considerations
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. This temporary low mood is sometimes called 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.
The patient's motivation for considering surgery should be discussed during an appropriate assessment. 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. Surgery may not relieve the underlying concern. A psychological evaluation or professional support may be recommended before surgery when concerns are identified.
Ways to Lower Cosmetic Surgery Risks
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.
- Confirm through your province or territory's college of physicians and surgeons that the doctor is licensed and in good standing.
- Discuss the surgical location, its safety procedures, infection-control practices, and ability to handle emergencies.
- Give the surgical team accurate information about diagnoses, operations, prescriptions, supplements, substances, and allergies.
- Follow instructions about fasting, medication changes, testing, and stopping nicotine.
- When needed, organize transportation and early postoperative support from a responsible adult.
- Understand the recovery timeline before booking work, travel, exercise, or major events.
- Go to every scheduled postoperative visit and quickly contact the surgical team about unexpected symptoms.
- Your recovery should not be compared with social media images, promotional content, or another person's timeline.
- Do not make an early decision about revision, because the tissues may require many months to heal and stabilize.
Finding a Qualified Canadian Cosmetic Surgeon
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. Royal College certification is valuable, but it should be considered alongside relevant experience, patient communication, emergency planning, surgical environment, and postoperative support.
Questions to ask during a cosmetic surgery consultation include:
- What professional education and certifications have you completed?
- How often do you perform this procedure?
- 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 rare but serious risks should I understand?
- Which medical professional will administer and monitor my anesthesia?
- How can I obtain care if a problem develops at night or on a weekend?
- Which hospital or emergency facility would treat me if a serious problem occurred?
- How many postoperative appointments are provided as part of the surgical plan?
- What costs could arise if I need treatment or revision surgery?
Informed Consent for Cosmetic Surgery
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. The surgeon should also explain risks that may have particular importance because of the patient's occupation, health, daily activities, or individual goals.
A patient should never feel rushed to sign. When medical language or a possible complication is confusing, the patient should request a clearer explanation. Taking notes, involving a support person, and reviewing written material outside the clinic can support an informed decision.
Warning Signs After Cosmetic Surgery
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:
- Breathing problems, chest discomfort, bloody coughing, or fainting
- One-sided leg swelling, tenderness, warmth, or discolouration
- Uncontrolled bleeding or a sudden increase in swelling
- Intense pain that does not improve after taking the recommended medicine
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Confusion, extreme weakness, or difficulty staying awake
- Skin that becomes very pale, dark, blistered, or cold to the touch
- Loss of sight, intense eye pain, or an abrupt disturbance in vision
- Persistent vomiting that prevents normal hydration
- 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.
Financial Risks and Health Coverage 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.
Before an operation, patients should ask who pays for treatment if a complication develops. Health coverage for complications varies based on medical necessity, treatment setting, and the applicable provincial or territorial insurance plan. Travel, accommodation, nursing assistance, missed work, child care, and revision surgery can create additional expenses.
Patients considering medical tourism should think about who will provide follow-up care after returning to Canada. A lower initial price may not include management of infection, wound problems, blood clots, implant complications, or revision surgery.
Evaluating the Advantages and Risks of Cosmetic Surgery
Patients should consider surgery only when their goals are achievable, their health is suitable, and they understand the risks and recovery. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection.
Take time to compare the expected benefit with the medical, emotional, practical, and financial risks. Consider whether you can follow the recovery plan, accept visible scars, manage time away from work, and cope with the possibility of an imperfect result.
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.
Making an Informed Decision
Being aware of possible complications is not the same as believing they are certain to happen. Instead, risk awareness allows patients to decide using reliable facts rather than marketing, online trends, or cost as the only factor.
Learn about the procedure, review your personal risk factors, confirm the surgeon's qualifications, ask detailed questions, and plan for a full recovery. A complete understanding of the likely improvements, procedure limitations, available options, and associated risks helps patients determine whether cosmetic surgery is appropriate for them.
