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, but no operation is entirely predictable. 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. 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. Others may require medication, hospital care, revision surgery, or long-term follow-up.
Canadian patients should receive understandable information about benefits, material risks, available alternatives, recovery demands, and the possible effects of choosing no 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 Risks Can Cosmetic Surgery Involve?
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. Swelling, bruising, soreness, cosmetic surgeons near me numbness, tightness, fatigue, and mild drainage may be normal during early healing. A complication is different. A complication extends beyond normal recovery and may need medical care.
Potential problems associated with plastic surgery include:
- Bleeding or a collection of blood called a hematoma
- Incision-site or deep-tissue infection
- A collection of fluid called a seroma
- Blood clots affecting the legs or lungs
- Slow wound healing or separation of the incision
- Noticeable, raised, widened, or uneven scars
- Nerve-related problems, including numbness or unusual sensation
- Skin, fat, or tissue loss caused by poor blood supply
- 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
- Additional medical treatment or a revision operation
Major complications do not happen often, but patients should understand that they remain possible. 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
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.
Soreness After Cosmetic Surgery
The amount of pain experienced depends on both the procedure and the individual. Patients may notice aching, tightness, burning, or tenderness around the treated area. Discomfort is normally expected to improve gradually during healing. Prompt medical advice is needed if pain suddenly worsens, begins spreading, or appears with fever, redness, breathing difficulty, or unexpected swelling.
Postoperative Swelling and Bruising
Swelling develops when inflammation allows fluid to collect in and around the treated area. The early result can remain difficult to assess until swelling subsides over the following 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.
The outcome of surgery should not be assessed before healing has progressed. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Changes in Feeling After Surgery
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. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. 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. Driving, exercise, heavy lifting, swimming, and returning to work may be restricted. Failing to follow activity restrictions may raise the risk of bleeding, swelling, wound breakdown, and other problems.
Potential Surgical Complications
Postoperative Bleeding and Hematoma
A limited amount of bleeding around the incision may be expected. When bleeding is more substantial, blood may collect under the skin or in the surgical site and form a hematoma. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
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.
Infection
An infection can develop in the skin, incision, tissue, or around an implant. An infection may cause increasing warmth, redness, swelling, pain, discharge resembling pus, fever, chills, or a bad smell.
An infection can require medication, incision care, removal of fluid, or an additional procedure. 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.
Postoperative Seroma
A seroma develops when a pocket of clear fluid forms under the surgical tissues. Seromas occur more often after operations that leave a broad space under the tissue, including tummy tuck surgery, body lifts, breast procedures, and extensive liposuction.
Small seromas may resolve as the body absorbs the fluid. A larger seroma may require drainage on one or several occasions. Untreated fluid can place pressure on the incision, affect healing, or become infected.
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. 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.
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.
Wound problems may require dressings, antibiotics, removal of damaged tissue, or additional surgery. 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.
Skin or Tissue Necrosis
Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to die. This complication can occur after procedures that lift, tighten, or reposition large sections of tissue. Smoking and nicotine use are major preventable risk factors because nicotine narrows blood vessels and reduces oxygen delivery.
The extent of tissue damage determines which treatment is required. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery.
Risks Related to Anesthesia
Depending on the operation, cosmetic surgery can involve local anesthetic, sedating medication, general anesthesia, or multiple methods together. The safest choice depends on the operation, the patient's medical history, the expected length of surgery, and the surgical setting.
Potential complications connected with anesthesia include:
- Postoperative nausea or vomiting
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- A headache or irritation of the throat
- Allergic or medication reactions
- Changes in blood pressure or heart rhythm
- Problems with breathing
- Stomach contents entering the lungs, known as aspiration
- Damage to teeth, lips, or the airway
- Serious heart, lung, or neurological complications
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.
Scarring and Changes to the Skin
Any procedure that cuts the skin creates a scar. Incisions are often positioned in natural creases, along hairlines, or beneath clothing, although no scar can be removed entirely.
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 Scars and Keloids
A hypertrophic scar becomes thick or raised but stays within the original wound. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. Patients should inform their surgeon if they or close family members have developed raised or unusual scars.
Raised or visible scars may be treated with silicone, compression, copyright injections, laser procedures, or surgical revision. Scar treatment may improve texture and appearance, but it cannot ensure that a hypertrophic scar or keloid will never come back.
Changes in Skin Colour and Texture
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. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
Aesthetic Risks and Unsatisfactory Results
A technically successful operation does not always produce the appearance a patient expected. Healing is affected by anatomy, skin elasticity, age, previous surgery, scar formation, and natural differences between the two sides of the body.
Appearance-related problems may include:
- Ongoing asymmetry
- Irregular or uneven body contours
- Under-correction or over-correction
- An unnatural or overly tight appearance
- Alterations in shape while swelling resolves
- Implant position problems
- Scarring that is prominent or difficult to conceal
- Recurrence of sagging or tissue laxity over 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
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. 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
Although many operations share common complications, every cosmetic procedure has its own specific risks.
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
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. A revision nose operation is often more challenging because the first surgery changes the cartilage and creates internal scarring.
Eyelid Surgery Risks
After blepharoplasty, patients may develop dry eyes, irritation, blurred vision, trouble shutting the eyelids, lid malposition, asymmetry, scarring, orbital bleeding, or changes in eyesight. Immediate medical evaluation is needed for intense eye pain or a sudden visual disturbance.
Breast Surgery Risks
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. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. Patients should not assume that breast implants will remain in place permanently without further care. Health Canada also provides safety information about uncommon conditions linked with certain breast implants, including breast implant-associated anaplastic large cell lymphoma.
Possible Liposuction Complications
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.
Possible Tummy Tuck and Body Lift Complications
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. Seroma, blood clots, infection, necrosis, delayed wound healing, numbness, noticeable scars, and altered belly button position may occur. Activity and lifting restrictions can remain in place for a number of weeks.
Possible Fat Grafting Complications
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. 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.
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.
Risk factors may include:
- Cigarette smoking, vaping, or any form of nicotine use
- Diabetes that is not well controlled
- Cardiac, respiratory, renal, liver, or vascular conditions
- A clotting or bleeding condition, or previous blood clots
- A high body mass index or significant changes in weight
- Sleep apnea
- Conditions affecting the immune system
- Inadequate nutrition or serious 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
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.
Psychological and Emotional Risks
Cosmetic surgery can affect emotional health as well as physical health. Swelling, bruising, fatigue, and temporary lifestyle restrictions may leave some patients feeling worried, frustrated, or low. The term postoperative blues is sometimes used to describe this temporary decline in mood.
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.
A careful cosmetic surgery consultation should examine why the patient wants the procedure. 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. Changing the physical feature does not necessarily treat the underlying mental health condition. In suitable cases, the surgeon may delay treatment and advise the patient to seek mental health assessment or counselling first.
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.
- Carefully follow all directions related to eating, drinking, preoperative tests, medication adjustments, and nicotine cessation.
- 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.
- Follow-up care should not be skipped, and abnormal changes should be reported without delay.
- Avoid judging your recovery against filtered photographs or the healing experience of someone else.
- Allow swelling and scar tissue to settle fully before considering corrective surgery.
Finding a Qualified Canadian Cosmetic Surgeon
In Canada, physicians are licensed and regulated by provincial and territorial authorities. The public directory of the appropriate college of physicians and surgeons can be used to check licensing, specialty registration, and listed practice details.
Canadian patients can ask if their surgeon has been certified in plastic surgery by the Royal College of Physicians and Surgeons of Canada. While certification matters, patients should also assess procedure-specific experience, communication, the quality of the facility, aftercare, and the surgeon's approach to complications.
Useful questions for a cosmetic surgery consultation include:
- What professional education and certifications have you completed?
- How many times have you carried out this operation?
- Does my medical history and physical anatomy make me an appropriate candidate?
- What are the most common complications 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?
- What emergency plan is in place if I need urgent medical treatment?
- What follow-up visits are included?
- Which additional expenses would I be responsible for if a complication or revision occurs?
Informed Consent for Cosmetic Surgery
Informed consent involves more than placing a signature on a document. The process requires clear communication so that the patient can make a knowledgeable and voluntary choice.
The consent process should cover the nature of the procedure, expected benefits, important risks, reasonable alternatives, recovery, limitations, and what could happen without treatment. Any complication that could significantly affect the patient's medical condition, employment, lifestyle, or priorities should receive special attention.
Patients should have enough time to review consent information without being pressured. Questions should be asked whenever risks, terminology, or instructions are not fully understood. It can be helpful to take notes, bring a trusted person to the consultation, and review written instructions at home.
Warning Signs After Cosmetic Surgery
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:
- Breathing problems, chest discomfort, bloody coughing, or fainting
- Sudden swelling, pain, redness, or warmth in one leg
- Uncontrolled bleeding or a sudden increase in swelling
- Intense pain that does not improve after taking the recommended medicine
- High fever, chills, spreading redness, or pus-like drainage
- Confusion, extreme weakness, or difficulty staying awake
- Skin that becomes very pale, dark, blistered, or cold to the touch
- An emergency eye symptom such as severe pain, sudden visual change, or vision loss
- Repeated vomiting or an inability to keep fluids down
- Any problem your surgeon specifically described as requiring emergency care
Emergency medical services should be contacted immediately for potentially life-threatening complications. 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.
The financial responsibility for postoperative problems should be clarified in advance. Health coverage for complications varies based on medical necessity, treatment setting, and the applicable provincial or territorial insurance plan. Patients should budget for possible travel, lodging, caregiving, time away from employment, child care, and future revision surgery.
Patients considering medical tourism should think about who will provide follow-up care after returning to Canada. Lower upfront fees may become more expensive if postoperative infection, wound breakdown, clotting, implant complications, or revision treatment is required.
Evaluating the Advantages and Risks of Cosmetic Surgery
The decision to have cosmetic surgery should be based on realistic goals, good health, informed consent, and a clear understanding of recovery. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection.
Before deciding, compare what the operation may achieve with its physical, psychological, practical, and economic consequences. 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. A decision not to operate is sometimes the safest and most responsible form of patient care.
Making an Informed Decision
Understanding the risks of cosmetic surgery does not mean assuming that complications will occur. 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. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
