Through cosmetic surgery, patients may refine the shape, proportions, or appearance of their face or body. For some people, it can also increase comfort with a physical feature that has caused distress for years. However, every operation involves some degree of uncertainty. A careful decision about cosmetic surgery should include a clear understanding of its possible risks.
A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. Anesthesia, bleeding, infection, healing difficulties, unexpected reactions, and the body's response to an operation can all cause problems. Some problems resolve with simple treatment and do not cause lasting harm. Others may require medication, hospital care, revision surgery, or long-term 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. 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 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. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. A complication is different. It is a problem that goes beyond the expected recovery process and may require medical treatment.
Potential problems associated with plastic surgery include:
- A hematoma, which is a collection of blood, or other excessive bleeding
- Infection at the incision or within deeper tissue
- 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
- Nerve injury, numbness, or altered sensation
- Tissue damage or loss resulting from inadequate blood flow
- Allergic or adverse reactions involving anesthesia, medication, adhesives, or surgical materials
- Unevenness, contour irregularities, or an unsatisfactory appearance
- Changes in function, such as breathing, movement, or sensation
- The need for additional treatment or revision 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.
Expected Short-Term Effects of Cosmetic Surgery
Some discomfort and physical change are part of normal healing. 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. As recovery progresses, pain should generally become less intense and easier to control. Pain that suddenly becomes severe, spreads, or occurs with fever, redness, shortness of breath, or unusual swelling should be reported promptly.
Postoperative Swelling and Bruising
Swelling develops when inflammation allows fluid to collect in and around the treated area. The early result can remain difficult to assess until swelling subsides over the following weeks or months. Small blood vessels can release blood under the skin, creating bruising. Patients undergoing face surgery, breast surgery, liposuction, or body contouring may experience noticeable bruising and swelling.
Patients should not judge the final result too early. Remaining swelling may temporarily affect shape, balance, and the texture of the skin.
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. Sensation often improves as nerves recover, but complete recovery cannot be guaranteed. There is a possibility that altered feeling will not fully resolve.
Activity Limitations During Recovery
Assistance may be needed for travel, food preparation, child care, pet care, housework, and daily personal needs. Patients may be temporarily unable to drive, exercise, lift heavy objects, swim, or resume their jobs. 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. When bleeding is more substantial, blood may collect under the skin or in the surgical site and form a hematoma. Increasing tenderness, firmness, swelling, discolouration, or an abrupt difference between two sides may indicate a hematoma.
A small hematoma may only need monitoring, but a larger one may require drainage. In certain cases, the patient may need to return to the operating room.
Surgical Infection
Infection may affect the skin, surgical cut, deeper tissue, or the area surrounding 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. 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.
A minor fluid collection can sometimes disappear as the body reabsorbs it. Larger ones may need to be drained, sometimes more than once. A persistent seroma can create pressure, interfere with wound healing, and increase the chance of infection.
Deep Vein Thrombosis and Pulmonary Embolism
Deep vein thrombosis, known as DVT, develops when a clot forms in one of the body's deep veins, usually in a leg. When part of a deep vein clot moves into the lungs, it may block blood flow and cause a pulmonary embolism. This is a medical emergency.
Risk may increase with long operations, limited movement, previous blood clots, certain medications, nicotine use, obesity, some medical conditions, and combining multiple procedures. Depending on the patient, preventive steps may involve getting up early, using compression equipment or garments, staying hydrated, or taking prescribed blood thinners.
Problems With Incision 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.
Incision problems may need wound care, antibiotics, surgical cleaning, or further corrective 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.
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. Nicotine exposure is an important avoidable risk because it constricts blood vessels and limits oxygen reaching the tissues.
Treatment depends on the amount of tissue affected. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery.
Anesthesia Risks in Cosmetic Surgery
Cosmetic procedures may be performed with local anesthesia, sedation, general anesthesia, or a combination of these methods. The safest choice depends on the operation, the patient's medical history, the expected length of surgery, and the surgical setting.
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
- Allergic or medication reactions
- Abnormal blood pressure or irregular heart rhythm
- Problems with breathing
- Aspiration, which occurs when material from the stomach reaches the lungs
- 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. The safety of the operation can be reduced when important health information is omitted.
Scarring and Changes to the Skin
A surgical procedure that breaks the skin will always leave some degree of scarring. 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. Genetic factors, skin characteristics, pressure on the incision, infection, sunlight, wound care, surgical location, and procedure type all influence the finished scar.
Hypertrophic Scars and Keloids
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. 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
Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. Alterations in colour or texture may improve, but they can also remain long term. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
Cosmetic Outcome Risks and Patient Dissatisfaction
A procedure can be medically and technically successful while still producing a result the patient did not anticipate. Individual anatomy, skin flexibility, age, past procedures, scarring, and natural asymmetry all affect healing.
Possible aesthetic concerns include:
- Ongoing asymmetry
- Irregular or uneven body contours
- Too little or too much correction
- An artificial-looking or over-tightened outcome
- A changing contour as postoperative swelling decreases
- An implant that shifts, rotates, or sits incorrectly
- Noticeable scars or scars in an unfavourable location
- Gradual recurrence of skin or tissue laxity
- Patient dissatisfaction even when the result is medically acceptable
Visual examples and digital imaging can guide consultation discussions, although no patient can be guaranteed the same outcome. Anatomy and healing responses vary from one person to another.
The Possibility of Revision Surgery
When problems occur or the outcome may benefit from improvement, revision cosmetic surgery can be considered. Revision surgery carries risks of its own. Because scarred tissues may be less flexible and have reduced circulation, revision procedures can be more difficult.
Before proceeding, patients should understand exactly what is included in the surgeon's or clinic's revision policy. 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
Although many operations share common complications, every cosmetic procedure has its own specific risks.
Risks of Facelift and Neck Lift Surgery
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. Smoking, vaping, and other nicotine exposure can significantly raise the chance of skin loss and delayed healing.
Rhinoplasty Risks
After nose surgery, patients may experience persistent swelling, nosebleeds, infection, asymmetry, smell changes, irregular contours, septal perforation, collapse of nasal support, or obstructed breathing. 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.
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.
Breast Surgery Risks
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.
Patients with breast implants face additional concerns that can develop over time. These include capsular contracture, implant rupture, deflation, rippling, movement, rotation, pain, and the need for future monitoring or surgery. Implants are not lifetime devices. Patients in Canada can review Health Canada information about uncommon implant-related conditions, such as breast implant-associated anaplastic large cell lymphoma.
Liposuction Risks
Liposuction complications may include contour irregularities, dents, rippling, loose skin, fluid imbalance, numbness, seroma, infection, internal injury, fat embolism, and lidocaine toxicity when local anesthetic is used. Removing larger volumes of fat or treating several body areas may increase medical stress and recovery demands.
Risks of Abdominoplasty and Body Lift Surgery
Tummy tuck and body lift procedures require long incisions and repositioning of broad tissue areas. Possible complications include fluid buildup, DVT, infection, tissue loss, incision opening, reduced sensation, visible scars, and changes in navel shape or placement. Recovery may involve several weeks of limited movement and physical activity.
Risks of Fat Transfer
During fat grafting, fat is taken from one body area and placed into a different location. The body naturally absorbs some transferred fat, potentially reducing volume or creating asymmetry. Other risks include fat necrosis, cysts, calcification, infection, oil cysts, and accidental injection into a blood vessel. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area.
Who May Face Greater Cosmetic Surgery Risks?
Some health and lifestyle factors can raise the chance of complications. Before proceeding, some patients require tests, adjustments to treatment, weight changes, nicotine cessation, or approval from another medical professional.
The likelihood of complications may increase with:
- Exposure to nicotine through smoking, vaping, gum, patches, or other products
- Diabetes with unstable or elevated blood sugar
- Heart, lung, kidney, liver, or blood vessel disease
- A bleeding disorder or history of blood clots
- Obesity or major weight changes
- Obstructive sleep apnea
- Immune system disorders
- Poor nutrition or significant anemia
- Earlier surgery or radiation therapy involving the same area
- Drugs, vitamins, or supplements that interfere with clotting or tissue repair
- Unrealistic expectations or untreated mental health concerns that affect decision-making
The presence of one or more risk factors does not automatically prevent cosmetic surgery. 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.
When a patient's expectations exceed the realistic limits of surgery, deeper or longer-lasting disappointment may follow. 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. An operation may fail to resolve the deeper psychological distress. 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.
- Work with a properly trained physician whose practice includes the cosmetic operation you are considering.
- Confirm through your province or territory's college of physicians and surgeons that the doctor is licensed and in good standing.
- 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.
- When needed, organize transportation and early postoperative support from a responsible adult.
- Review the expected healing schedule before arranging employment, trips, strenuous activity, or important occasions.
- Go to every scheduled postoperative visit and quickly contact the surgical team about unexpected symptoms.
- Avoid judging your recovery against filtered photographs or the healing experience of someone else.
- Do not make an early decision about revision, because the tissues may require many months to heal and stabilize.
Choosing a Cosmetic Surgeon in Canada
In Canada, physicians are licensed and regulated by provincial and territorial authorities. 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. Certification is one useful qualification to review, but patients should also consider experience with the specific procedure, complication management, communication, surgical setting, and follow-up care.
During the consultation, patients may wish to ask:
- 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?
- Which problems do your patients experience most often after this operation?
- What low-frequency, high-impact risks should I know about?
- Who will provide anesthesia?
- What happens if I have a complication after business hours?
- Which hospital or emergency facility would treat me if a serious problem occurred?
- What follow-up visits are included?
- Could I face extra surgeon, facility, anesthesia, medication, or revision fees?
Informed Consent for Cosmetic Surgery
Informed consent is more than signing a form. The process requires clear communication so that the patient can make a knowledgeable and voluntary choice.
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.
No one should be pushed into signing a surgical consent form quickly. Ask for clarification when a term or complication is unclear. Taking notes, involving a support person, and reviewing written material outside the clinic can support an informed decision.
Warning Signs After Cosmetic Surgery
Your surgical team should provide specific instructions about when and how to seek help. The surgical team should be contacted quickly if symptoms become worse, appear unusual, or do not match the expected healing process.
Urgent warning signs may include:
- Chest pain, shortness of breath, coughing blood, or fainting
- One-sided leg swelling, tenderness, warmth, or discolouration
- Significant bleeding or swelling that expands quickly
- Severe pain that is not controlled by prescribed medication
- 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
- Sudden vision loss, severe eye pain, or major visual changes
- Ongoing vomiting or difficulty drinking without becoming sick
- Any symptom the surgical team identified as an emergency
When a symptom could represent a life-threatening emergency, call 911 or go to an emergency department. Severe breathing difficulty, chest pain, unconsciousness, heavy bleeding, and other emergency symptoms should not wait until normal clinic hours.
Financial Considerations for Cosmetic Surgery in Canada
When a procedure is intended only to improve appearance, public health insurance in Canada will usually not cover it. Patients usually pay for the surgeon, anesthesia, operating facility, implants, garments, prescriptions, testing, and other related expenses.
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.
Medical tourists need to determine professional cosmetic plastic surgery 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
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. Think about your ability to obey postoperative instructions, live with scars, take enough time off, and emotionally manage an outcome that is not ideal.
When complications are too likely, benefits are small, or expectations cannot be met safely, an experienced surgeon may recommend against operating. A decision not to operate is sometimes the safest and most responsible form of patient care.
Deciding Whether Cosmetic Surgery Is Right for You
Understanding the risks of cosmetic surgery does not mean assuming that complications will occur. It means making a thoughtful decision based on accurate information rather than advertising, social media trends, or price alone.
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.
