Through cosmetic surgery, patients may change the shape, proportions, or appearance of their face or body. It may also help a person feel more comfortable with a feature that has bothered them for years. 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.
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 problems resolve with simple treatment and do not cause lasting harm. More serious problems may call for medication, hospital treatment, revision surgery, or ongoing medical follow-up.
Patients in Canada should receive clear information about the expected benefits, material risks, alternatives, recovery requirements, and possible consequences of not having treatment. During a careful consultation, patients should be able to consider the facts without being rushed. 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?
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.
Minor side effects are expected after many procedures. During early recovery, swelling, bruising, tenderness, numbness, tightness, tiredness, and light drainage may be normal. Expected healing effects and surgical complications are different. A complication extends beyond normal recovery and may need medical care.
Plastic surgery complications may include the following:
- A hematoma, which is a collection of blood, or other excessive bleeding
- Infection at the incision or within deeper tissue
- A collection of fluid called a seroma
- 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
- Skin, fat, or tissue loss caused by poor blood supply
- Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials
- Asymmetry, contour problems, or an unwanted appearance
- Problems with normal function, including breathing, motion, or sensation
- Additional medical treatment or a revision operation
Although serious complications are rare, they must still be reviewed before surgery. Rare risks may include severe infection, major blood loss, organ injury, heart problems, stroke, pulmonary embolism, permanent disability, or 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.
Postoperative Pain and Tenderness
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. As recovery progresses, pain should generally become less intense and easier to control. 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 develops when inflammation allows fluid to collect in and around the treated area. 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.
Patients are advised to avoid making early judgments about their final appearance. Remaining swelling may temporarily affect shape, balance, and the texture of the skin.
Altered Sensation and Numbness
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. Nerve recovery often improves sensation over time, but normal feeling may not return completely. There is a possibility that altered feeling will not fully resolve.
Temporary Limits on Activity
Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. Driving, exercise, heavy lifting, swimming, and returning to work may be restricted. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Potential Surgical Complications
Postoperative Bleeding and Hematoma
A limited amount of bleeding around the incision may be expected. More significant bleeding can form a hematoma, which is a collection of blood beneath the skin or inside the surgical area. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
Some hematomas can be observed, while others must be drained. 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.
Antibiotics, specialized wound care, drainage, or further surgery may be needed to treat an infection. Removal can be required when infection develops around a breast implant or surgical device. Smoking, uncontrolled diabetes, poor nutrition, and problems with blood circulation can raise the risk of infection or make it harder to treat.
Seroma
A seroma is a pocket of clear fluid that collects under the skin. It is more common after procedures that create a large space beneath the tissue, such as tummy tuck surgery, body lift surgery, breast surgery, or extensive liposuction.
Small seromas may resolve as the body absorbs the fluid. Larger ones may need to be drained, sometimes more than once. Untreated fluid can place pressure on the incision, affect healing, or become infected.
Blood Clot Complications
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. A pulmonary embolism requires emergency medical care.
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.
Problems With Incision Healing
A surgical wound may take longer than expected to close or may start to open. 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. Secondary intention healing allows an open wound to fill and close naturally from the bottom upward. Healing in this way often takes more time and can result in a more noticeable scar.
Skin or 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. Possible treatment includes wound management, removal of dead tissue, a skin graft, reconstructive surgery, or revision at a later date.
Risks Related to Anesthesia
Depending on the operation, cosmetic surgery can involve local anesthetic, sedating medication, general anesthesia, or multiple methods together. The most suitable anesthesia plan is based on the type of surgery, patient health history, procedure duration, and location where surgery takes place.
Anesthesia may be associated with the following risks:
- Postoperative nausea or vomiting
- Light-headedness, confusion, or extended sleepiness
- 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
- Injury to the teeth, lips, mouth, or 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. Withholding medical or lifestyle information may increase the risks of anesthesia and surgery.
Scarring and Changes to the Skin
Whenever an incision is made through the skin, a scar will form. Surgeons usually place incisions aesthetic transformation 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
Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. Keloid tissue spreads past the edges of the initial incision. A history of hypertrophic scars or keloids, whether personal or familial, should be discussed before an operation.
Possible treatments include silicone products, pressure therapy, copyright injections, laser treatment, or scar 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
Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin texture. These effects may be temporary or permanent. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
The Risk of an Unwanted Cosmetic Result
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
- 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
- Gradual recurrence of skin or tissue laxity
- Dissatisfaction despite an acceptable medical result
Photos, digital simulations, and before-and-after galleries can support discussion, but they cannot guarantee an identical outcome. Every patient's tissues, proportions, and recovery process are unique.
Revision Cosmetic Surgery
When problems occur or the outcome may benefit from improvement, revision cosmetic surgery can be considered. Revision surgery carries risks of its own. 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. The first surgical fee may not cover a revision surgeon, facility charges, anesthesia, new implants, prescriptions, travel, or lost work time.
Procedure-Specific Cosmetic Surgery Risks
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. Nicotine use can greatly increase the risk of skin-healing problems.
Risks of Nose Surgery
After nose surgery, patients may experience persistent swelling, nosebleeds, infection, asymmetry, smell changes, irregular contours, septal perforation, collapse of nasal support, or obstructed breathing. The final shape may take a year or longer to become clear. Scar formation and altered cartilage can make secondary rhinoplasty more complex.
Blepharoplasty 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.
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. Hematoma, infection, fat necrosis, poor healing, and altered nipple or areola position are also possible.
Patients with breast implants face additional concerns that can develop over time. Capsular contracture, rupture, deflation, rippling, displacement, rotation, pain, ongoing imaging, and future surgery may occur with breast implants. Breast implants are not designed to last for an entire lifetime. Health Canada publishes safety guidance concerning rare illnesses associated with some 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. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated.
Tummy Tuck and Body Lift Risks
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. Patients may need several weeks of movement restrictions.
Risks of Fat Transfer
Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. Because a portion of the injected fat may not survive, the final fullness and balance can change. Other risks include fat necrosis, cysts, calcification, infection, oil cysts, and accidental injection into a blood vessel. The location where fat is injected, such as the face, breasts, or buttocks, affects the type and seriousness of potential complications.
Who May Face Greater Cosmetic Surgery Risks?
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:
- 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 clotting or bleeding condition, or previous blood clots
- A high body mass index or significant changes in weight
- Obstructive sleep apnea
- Conditions affecting the immune system
- 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. It means the surgeon must decide whether the procedure can be performed safely and whether changes are needed before proceeding.
Psychological Effects of Cosmetic Surgery
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. 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. A cosmetic procedure can modify the body, but it does not guarantee emotional confidence, relationship improvement, career advancement, or solutions to unrelated personal concerns.
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. 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
Cosmetic surgery always carries some risk, yet careful planning can reduce the likelihood of complications.
- 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.
- Ask where the procedure will be performed and what safety, emergency, and infection-control systems are available.
- Disclose your entire health history, including previous surgery, allergies, medications, supplements, alcohol, cannabis, and nicotine use.
- 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.
- Follow-up care should not be skipped, and abnormal changes should be reported without delay.
- Do not compare your healing speed with edited images or another patient's recovery.
- Allow swelling and scar tissue to settle fully before considering corrective surgery.
Choosing a Cosmetic Surgeon in Canada
Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. Patients can search the public register of the applicable college of physicians and surgeons to confirm a doctor's licence, registered specialty, and available practice information.
Another useful question is whether the doctor holds plastic surgery certification from the Royal College of Physicians and Surgeons of Canada. While certification matters, patients should also assess procedure-specific experience, communication, the quality of the facility, aftercare, and the surgeon's approach to complications.
Questions to ask during a cosmetic surgery consultation include:
- What training and certification do you have?
- 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?
- Which medical professional will administer and monitor my anesthesia?
- What happens if I have a complication after business hours?
- Where would I receive emergency care if needed?
- Which follow-up visits and services are included in the fee?
- Which additional expenses would I be responsible for if a complication or revision occurs?
What Informed Consent Should Include
Informed consent involves more than placing a signature on a document. It should be a continuing conversation that allows the patient to decide freely after receiving adequate information.
A proper consent discussion includes the procedure itself, expected improvement, significant complications, alternative options, recovery requirements, limitations, and the choice to decline 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. Patients may benefit from writing down information, attending with someone they trust, and reading the documents again at home.
Postoperative Warning Signs
Patients should receive clear directions about warning signs, emergency care, and after-hours communication. Unexpected or worsening symptoms that fall outside the recovery instructions should be reported without delay.
Potential emergency signs after cosmetic surgery include:
- Chest pain, shortness of breath, coughing blood, or fainting
- Sudden swelling, pain, redness, or warmth in one leg
- Significant bleeding or swelling that expands quickly
- Severe pain that is not controlled by prescribed medication
- High fever, chills, spreading redness, or pus-like drainage
- Disorientation, marked weakness, or excessive drowsiness
- A pale, dark, blistered, or unusually cold area of skin
- An emergency eye symptom such as severe pain, sudden visual change, or vision loss
- Repeated vomiting or an inability to keep fluids down
- Any symptom the surgical team identified as an emergency
Emergency medical services should be contacted immediately for potentially life-threatening complications. Patients should seek immediate care rather than waiting for the surgeon's office when serious bleeding, breathing problems, chest pain, fainting, or another critical symptom occurs.
Financial Considerations for Cosmetic Surgery in Canada
Canadian provincial and territorial health plans generally do not pay for operations performed solely for cosmetic reasons. Patients usually pay for the surgeon, anesthesia, operating facility, implants, garments, prescriptions, testing, and other related expenses.
The financial responsibility for postoperative problems should be clarified in advance. Coverage may depend on the medical service required, the location where treatment is provided, and the patient's provincial or territorial plan. 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.
Balancing the Benefits 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.
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. A decision not to operate is sometimes the safest and most responsible form of patient care.
How to Make an Informed Cosmetic Surgery 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.
Before surgery, research the operation, assess your health risks, verify medical credentials, ask thorough questions, and prepare for the complete healing period. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
