Through cosmetic surgery, patients may refine 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. However, every operation involves some degree of uncertainty. Understanding the risks of cosmetic surgery is an important part of deciding whether a procedure is right for you.
Although most patients heal without serious problems, no surgeon can guarantee perfection or eliminate every surgical risk. Complications may result from anesthetic medication, bleeding, infection, delayed healing, unexpected reactions, or an individual response to surgery. Some complications are temporary and easy to treat. 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. During a careful consultation, patients should be able to consider the facts without being rushed. Because cosmetic surgery is generally elective, patients should be free to postpone or refuse it if the possible risks are greater than the expected benefits.
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.
Many cosmetic procedures are followed by minor expected side effects. Swelling, bruising, soreness, numbness, tightness, fatigue, and mild drainage may be normal during early healing. A complication is different. It is a problem that goes beyond the expected recovery process and may require medical treatment.
Possible complications of plastic surgery include:
- A hematoma, which is a collection of blood, or other excessive bleeding
- 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
- Slow wound healing or separation of the incision
- Scars that become prominent, raised, wide, or uneven
- Damage to nerves, loss of feeling, or changes in sensation
- Skin, fat, or tissue loss caused by poor blood supply
- Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials
- Unevenness, contour irregularities, or an unsatisfactory appearance
- Functional changes affecting breathing, movement, or feeling
- A need for further care or corrective surgery
Serious complications are uncommon, but they are still important to discuss. Rare risks may include severe infection, major blood loss, organ injury, heart problems, stroke, pulmonary embolism, permanent disability, or death.
Common Early Effects During Cosmetic Surgery Recovery
A degree of discomfort and physical change is expected while the body heals. Patients should understand what is expected so they can tell the difference between routine recovery and a warning sign.
Soreness After Cosmetic Surgery
Each patient experiences pain differently, and some operations cause more discomfort than others. 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. For several weeks or even months, swelling may conceal the true result of surgery. Bruises form when tiny blood vessels are damaged and blood collects 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. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Changes in Feeling After Surgery
Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. Temporary changes such as tingling, numbness, tenderness, or reduced sensation may occur after surgery. Feeling frequently returns as the nerves heal, although full recovery is not certain. There is a possibility that altered feeling will not fully resolve.
Short-Term Activity Restrictions
Patients may need help with transportation, meals, child care, pet care, household work, and personal tasks. Restrictions may apply to driving, physical activity, lifting, swimming, and work. Ignoring these limits can increase swelling, bleeding, wound problems, and other complications.
Potential Surgical Complications
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.
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
An infection can develop in the skin, incision, tissue, or around an implant. Warning signs can include spreading redness, heat, swelling, worsening pain, pus-like fluid, fever, chills, or an unusual odour.
An infection can require medication, incision care, removal of fluid, or an additional procedure. An infected breast implant or other medical device may need to be removed. 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. 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.
The body may gradually absorb a small seroma without further treatment. Repeated drainage may be necessary when a significant seroma develops. A persistent seroma can create pressure, interfere with wound healing, and increase the chance of infection.
Blood Clots 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.
Long procedures, inactivity, earlier blood clots, some drugs, nicotine use, excess body weight, health conditions, and combined operations can increase the chance of DVT or pulmonary embolism. Depending on the patient, preventive steps may involve getting up early, using compression equipment or garments, staying hydrated, or taking prescribed blood thinners.
Delayed or Difficult 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.
Wound problems may require dressings, antibiotics, removal of damaged tissue, or additional surgery. Healing by secondary intention means allowing an open area to close gradually from the inside outward. Healing in this way often takes more time and can result in a more noticeable scar.
Loss of Tissue From Poor Blood Supply
Necrosis means that skin, fat, or another tissue does not receive enough blood and begins to 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.
The extent of tissue damage determines which treatment is required. It may involve wound care, removal of damaged tissue, skin grafting, reconstructive surgery, or a delayed revision.
Potential Complications of 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.
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
- Respiratory difficulty
- Aspiration, which occurs when material from the stomach reaches the lungs
- Injury to the teeth, lips, mouth, or airway
- Major complications involving the heart, lungs, or nervous system
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.
Cosmetic Surgery Scars and Skin Changes
Any procedure that cuts the skin creates a scar. Surgeons usually place incisions where they can be hidden within natural folds, hairlines, or clothing, but a scar cannot be erased completely.
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 Scars and Keloids
A hypertrophic scar becomes thick or raised but stays within the original wound. A keloid grows beyond the borders of the incision. A history of hypertrophic scars or keloids, whether personal or familial, should be discussed before an operation.
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
Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin 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.
Aesthetic Risks and Unsatisfactory Results
A technically successful operation does not always produce the appearance a patient expected. The body's response is shaped by age, anatomy, skin quality, earlier surgery, scar development, and normal side-to-side differences.
Potential cosmetic outcome concerns include:
- Unevenness that remains after healing
- Uneven contours or visible irregularities
- A result that is under-treated or over-treated
- An artificial-looking or over-tightened outcome
- Changes in shape as swelling settles
- Movement or poor positioning of an implant
- Scarring that is prominent or difficult to conceal
- Recurrence of sagging or tissue laxity over time
- Patient dissatisfaction even when the result is medically acceptable
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. 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. 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
Although many operations share common complications, every cosmetic procedure has its own specific risks.
Possible Facelift and Neck Lift Complications
Facelift and neck lift complications may include hematoma, facial nerve injury, hairline changes, hair loss near incisions, skin loss, contour irregularities, earlobe distortion, numbness, facial weakness, and visible scarring. Nicotine use can greatly increase the risk of skin-healing problems.
Possible Rhinoplasty Complications
Potential rhinoplasty complications include long-lasting swelling, bleeding, infection, unevenness, altered smell, contour problems, a hole in the septum, structural collapse, and nasal breathing difficulty. The final shape may take a year or longer to become clear. Revision rhinoplasty can be more difficult because of scar tissue and changes to the cartilage.
Possible Complications of Eyelid Surgery
Blepharoplasty risks include dry or irritated eyes, temporary blurred vision, difficulty closing the eyelids, eyelid malposition, asymmetry, scarring, bleeding behind the eye, and changes in vision. 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 advanced plastic surgery position are also possible.
Breast implants bring added long-term considerations. Capsular contracture, rupture, deflation, rippling, displacement, rotation, pain, ongoing imaging, and future surgery may occur with breast implants. 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.
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.
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. Patients may need several weeks of movement restrictions.
Risks of Fat Transfer
During fat grafting, fat is taken from one body area and placed into a different location. Because a portion of the injected fat may not survive, the final fullness and balance can change. 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.
Factors That Increase the Risk of Complications
A patient's health status and daily habits may make complications more likely. Before proceeding, some patients require tests, adjustments to treatment, weight changes, nicotine cessation, or approval from another medical professional.
Factors associated with higher surgical risk include:
- Smoking, vaping, or using nicotine products
- Diabetes with unstable or elevated blood sugar
- Heart, lung, kidney, liver, or blood vessel disease
- A bleeding disorder or history of blood clots
- A high body mass index or significant changes in weight
- Obstructive sleep apnea
- Immune system disorders
- Nutritional deficiencies or a low red blood cell count
- Scar tissue or circulation changes from prior operations or radiation
- Medications or supplements that affect bleeding or healing
- 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.
Psychological Effects of Cosmetic Surgery
The effects of cosmetic surgery may be psychological and emotional, not only physical. Some patients feel anxious, impatient, or discouraged while swollen, bruised, tired, and unable to follow their normal routine. The term postoperative blues is sometimes used to describe this temporary decline in mood.
When a patient's expectations exceed the realistic limits of surgery, deeper or longer-lasting disappointment may follow. Cosmetic surgery may change a physical feature, but it cannot guarantee confidence, repair a relationship, create career success, or solve broader personal problems.
The patient's motivation for considering surgery should be discussed during an appropriate assessment. 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. When appropriate, a surgeon may recommend psychological assessment or support before considering an operation.
Reducing the Chance of Surgical Complications
Although no operation can be made completely risk-free, thorough preparation can improve safety.
- Choose a properly qualified physician with training and experience relevant to 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.
- 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.
- 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.
- Do not make an early decision about revision, because the tissues may require many months to heal and stabilize.
How to Select a Cosmetic Surgeon in Canada
Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. 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.
Questions to ask during a cosmetic surgery consultation include:
- What training and certification do you have?
- How many times have you carried out this operation?
- 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 low-frequency, high-impact risks should I know about?
- Who will provide anesthesia?
- Who should I contact if I experience a complication outside normal clinic hours?
- Where would I receive emergency care if needed?
- What follow-up visits are included?
- Which additional expenses would I be responsible for if a complication or revision occurs?
What Informed Consent Should Include
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.
The consent process should cover the nature of the procedure, expected benefits, important risks, reasonable alternatives, recovery, limitations, and what could happen without treatment. Risks that are especially relevant to the patient's health, job, lifestyle, or personal priorities should also be discussed.
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
Patients should receive clear directions about warning signs, emergency care, and after-hours communication. Contact the clinic promptly when symptoms are unexpected, worsening, or different from the recovery plan.
Symptoms that may require urgent care 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
- Pain that remains severe despite the prescribed treatment plan
- Fever, chills, redness moving away from the incision, or drainage resembling pus
- Disorientation, marked weakness, or excessive drowsiness
- 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
- Ongoing vomiting or difficulty drinking without becoming sick
- A symptom listed as urgent in the postoperative instructions
Call 911 or seek emergency care when symptoms may be life-threatening. 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.
Cosmetic Surgery Costs and Canadian Health Coverage
When a procedure is intended only to improve appearance, public health insurance in Canada will usually not cover it. Out-of-pocket expenses may include the surgeon, anesthesia provider, operating room, medical devices, recovery clothing, prescriptions, laboratory work, and follow-up items.
Complication-related costs should be discussed before surgery. 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. Patients should budget for possible travel, lodging, caregiving, time away from employment, child care, and future revision surgery.
Medical tourists need to determine which Canadian provider, if any, will manage recovery and complications after their return. An inexpensive overseas package may exclude the cost of treating infection, poor healing, DVT, implant problems, and corrective operations.
Balancing the Benefits and Risks of Cosmetic Surgery
A sound decision about cosmetic surgery requires realistic expectations, appropriate health, informed consent, and knowledge of the healing process. A suitable patient recognizes that improvement is possible, but perfection is not.
Take time to compare the expected benefit with the medical, emotional, practical, and financial risks. 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.
When complications are too likely, benefits are small, or expectations cannot be met safely, an experienced surgeon may recommend against operating. Recommending against surgery can be a sign of careful and ethical medical practice.
Deciding Whether Cosmetic Surgery Is Right for You
Being aware of possible complications is not the same as believing they are certain to happen. It means making a thoughtful decision based on accurate information rather than advertising, social media trends, or price alone.
A safer decision involves understanding the procedure, identifying individual risk factors, checking the surgeon's qualifications, discussing concerns, and organizing postoperative care. Patients can make a more informed choice when they clearly understand expected benefits, realistic limits, non-surgical or surgical alternatives, and potential complications.
