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. Even so, all operations involve some uncertainty. Understanding the risks of cosmetic surgery is an essential part of deciding whether a procedure is right for you.
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 complications are temporary and easy to treat. More serious problems may call for medication, hospital treatment, revision surgery, or ongoing medical 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 careful consultation gives you time to consider this information without pressure. Most cosmetic procedures are optional, which means you can delay or decline surgery when its risks do not justify its likely benefits.
What Risks Can Cosmetic Surgery Involve?
Cosmetic surgery risks include any unwanted medical, functional, or aesthetic outcome linked to an operation. Risk levels vary according to the procedure, surgical method, treatment area, operation length, anesthesia type, and the patient's general health.
It is normal for patients to experience some minor effects after many operations. During early recovery, swelling, bruising, tenderness, numbness, tightness, tiredness, and light drainage may be normal. A complication is different. A complication extends beyond normal recovery and may need medical care.
Possible complications of plastic surgery include:
- Bleeding or a collection of blood called a hematoma
- Infection at the incision or within deeper tissue
- Seroma formation, which involves fluid collecting beneath the tissue
- Clots that form in a leg vein or travel to the lungs
- Slow wound healing or separation of the incision
- Noticeable, raised, widened, or uneven scars
- Damage to nerves, loss of feeling, or changes in sensation
- Loss of skin, fat, or other tissue because of reduced circulation
- Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products
- Aesthetic concerns such as asymmetry, poor contours, or an unwanted result
- Changes in function, such as breathing, movement, or sensation
- Additional medical treatment or a revision operation
Although serious complications are rare, they must still be reviewed before surgery. Possible rare complications include severe infection, major hemorrhage, organ damage, heart problems, stroke, a blood clot in the lungs, permanent impairment, and death.
Common Early Effects During Cosmetic Surgery Recovery
Some discomfort and physical change are part of normal healing. Knowing what normal healing looks like helps patients recognize when a symptom may be a warning sign.
Pain and Tenderness
Each patient experiences pain differently, and some operations cause more discomfort than others. Patients may notice aching, tightness, burning, or tenderness around the treated 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.
Postoperative Swelling and Bruising
Swelling is caused by inflammation and fluid moving into the treated tissues. 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. Facial procedures, liposuction, breast surgery, and body contouring can all cause visible swelling and bruising.
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
Surgery can affect tiny sensory nerves by moving, stretching, or cutting them. Some procedures commonly cause short-term numbness, tingling, increased sensitivity, or a decrease in feeling. Feeling frequently returns as the nerves heal, although full recovery is not certain. In some cases, changes in sensation may be permanent.
Short-Term Activity Restrictions
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.
Surgical and Medical Complications
Bleeding and Hematoma
A small amount of bleeding may occur around an incision. 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. Some hematomas require another operation to control the bleeding and remove collected blood.
Surgical Infection
Infection may affect the skin, surgical cut, deeper tissue, or the area surrounding an implant. Possible signs include increasing redness, warmth, swelling, pus-like drainage, worsening pain, fever, chills, or an unpleasant smell.
Antibiotics, specialized wound care, drainage, or further surgery may be needed to treat an infection. 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.
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. 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
A blood clot that forms in a deep vein, commonly within the leg, is called deep vein thrombosis, or DVT. If part of the clot travels to the lungs, it can cause a pulmonary embolism. A pulmonary embolism requires emergency medical care.
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. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate.
Problems With Incision Healing
Slow healing or separation of the incision can occur after cosmetic surgery. Reduced blood supply, infection, tension on the wound, nicotine exposure, certain medications, and medical conditions can interfere with healing.
Wound problems may require dressings, antibiotics, removal of damaged tissue, or additional surgery. When a wound is left to close slowly from its deeper layers toward the surface, the process is called healing by secondary intention. The recovery period may be extended, and the final scar may be more prominent.
Skin or Tissue Necrosis
When skin, fat, or other tissue loses its blood supply and starts to die, the condition is called necrosis. 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.
Anesthesia Risks in Cosmetic Surgery
Local anesthesia, sedation, general anesthesia, or a combination may be used during cosmetic surgery. Choosing an anesthesia method requires consideration of the operation, medical background, expected surgical time, and facility.
Anesthesia may be associated with the following risks:
- Postoperative nausea or vomiting
- Dizziness, confusion, or prolonged drowsiness
- Headache or sore throat
- Allergic or medication reactions
- Fluctuations in blood pressure or disturbances in heartbeat
- Problems with breathing
- Aspiration, which occurs when material from the stomach reaches the lungs
- Damage to teeth, lips, or the airway
- Major complications involving the heart, lungs, or nervous system
A preoperative health history should include every medication, vitamin, supplement, cannabis product, alcohol or nicotine habit, allergy, previous anesthetic reaction, and relevant diagnosis. Leaving out information can make anesthesia and surgery less safe.
Changes in Scarring, Colour, and Skin Texture
Any procedure that cuts the skin creates a scar. Surgeons usually place incisions where they can be hidden within natural folds, hairlines, or clothing, but a scar cannot be erased completely.
Scars often appear red, raised, firm, or darker during early healing. Over 12 months or longer, scar tissue can gradually fade and soften. 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
Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. Unlike a hypertrophic scar, a keloid extends outside the original boundaries of the wound. People with a personal or family history of abnormal scarring should tell their surgeon before surgery.
Possible treatments include silicone products, pressure therapy, copyright injections, laser treatment, or scar revision. Although treatment can make a scar less noticeable, recurrence of abnormal tissue remains possible.
Skin Colour and Texture Changes
Possible skin changes after surgery include darker or lighter pigment, redness, visible vessels, dents, hardness, and uneven texture. These effects may be temporary or permanent. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
The Risk of an Unwanted Cosmetic Result
A technically successful operation does not always produce the appearance a patient expected. Individual anatomy, skin flexibility, age, past procedures, scarring, and natural asymmetry all affect healing.
Potential cosmetic outcome concerns include:
- Unevenness that remains after healing
- Irregular or uneven body contours
- Too little or too much correction
- An unnatural or overly tight appearance
- Changes in shape as swelling settles
- Movement or poor positioning of an implant
- Visible or poorly placed scars
- A return of looseness or sagging with age and time
- Dissatisfaction despite an acceptable medical result
Visual examples and digital imaging can guide consultation discussions, although no patient can be guaranteed the same outcome. Every patient's tissues, proportions, and recovery process are unique.
The Possibility of Revision Surgery
Revision surgery may be considered when a complication occurs or when the result can be improved. A second procedure introduces another set of surgical risks. 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. 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.
Possible Rhinoplasty Complications
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. Scar formation and altered cartilage can make secondary rhinoplasty more complex.
Blepharoplasty Risks
Possible eyelid surgery complications include eye dryness, irritation, short-term blurred vision, incomplete eyelid closure, abnormal lid position, unevenness, scars, bleeding behind the eye, and visual changes. Severe eye pain or a sudden change in vision requires non-surgical plastic surgery urgent medical assessment.
Risks of Cosmetic Breast Surgery
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 position are also possible.
Breast implants bring added long-term considerations. These include capsular contracture, implant rupture, deflation, rippling, movement, rotation, pain, and the need for future monitoring or surgery. Implants are not lifetime devices. Health Canada publishes safety guidance concerning rare illnesses associated with some breast implants, including breast implant-associated anaplastic large cell lymphoma.
Risks of Liposuction
Liposuction may lead to dents, surface irregularities, skin looseness, fluid problems, numbness, fluid collection, infection, organ injury, fat embolism, or lidocaine toxicity when local anesthesia is involved. Removing larger volumes of fat or treating several body areas may increase medical stress and recovery demands.
Risks of Abdominoplasty and Body Lift Surgery
Large sections of skin and underlying tissue are moved during abdominoplasty and body lift surgery. Possible complications include fluid buildup, DVT, infection, tissue loss, incision opening, reduced sensation, visible scars, and changes in navel shape or placement. Patients may need several weeks of movement restrictions.
Fat Grafting Risks
Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. Some of the transferred fat will be absorbed, which can affect volume and symmetry. Fat grafting may also cause fat necrosis, cyst formation, calcium deposits, infection, oily fluid collections, or unintended injection into circulation. The safety concerns differ depending on whether fat is placed in the face, breasts, buttocks, or another area.
Factors That Increase the Risk of Complications
A patient's health status and daily habits may make complications more likely. Preoperative preparation may include laboratory testing, medication changes, weight management, stopping nicotine, or obtaining medical clearance.
The likelihood of complications may increase with:
- Cigarette smoking, vaping, or any form of nicotine use
- 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
- Obesity, unstable weight, or recent major weight loss or gain
- Obstructive 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
- 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. The surgeon needs to evaluate the level of risk and decide whether health or lifestyle changes are necessary before treatment.
Psychological Effects of Cosmetic Surgery
The effects of cosmetic surgery may be psychological and emotional, not only physical. Swelling, bruising, fatigue, and temporary lifestyle restrictions may leave some patients feeling worried, frustrated, or low. 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. Warning signs may include pressure from another person, repeated procedures without satisfaction, extreme focus on a minor feature, or the belief that one operation will completely transform a person's life.
Body dysmorphic disorder causes significant distress and preoccupation with appearance flaws that may seem minor or unnoticeable to others. 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.
Reducing the Chance of Surgical Complications
Cosmetic surgery always carries some risk, yet careful planning can reduce the likelihood of complications.
- Work with a properly trained physician whose practice includes the cosmetic operation you are considering.
- Check the doctor's licence, registration, and professional standing with the applicable provincial or territorial medical regulator.
- Discuss the surgical location, its safety procedures, infection-control practices, and ability to handle emergencies.
- Disclose your entire health history, including previous surgery, allergies, medications, supplements, alcohol, cannabis, and nicotine use.
- Complete required testing and obey instructions about fasting, medicines, supplements, smoking, vaping, and other nicotine products.
- 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.
- 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.
- Allow swelling and scar tissue to settle fully before considering corrective surgery.
How to Select a Cosmetic Surgeon in Canada
Medical regulation in Canada is handled at the provincial and territorial level. Patients may verify a physician's licence and registered specialty through the online register maintained by their provincial or territorial regulator.
Patients may also ask whether a surgeon is certified in plastic surgery by the Royal College of Physicians and Surgeons of Canada. Royal College certification is valuable, but it should be considered alongside relevant experience, patient communication, emergency planning, surgical environment, and postoperative support.
Useful questions for a cosmetic surgery consultation include:
- What are your surgical qualifications and specialty credentials?
- 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?
- Which uncommon but severe complications need to be considered?
- Who will provide anesthesia?
- How can I obtain care if a problem develops at night or on a weekend?
- Which hospital or emergency facility would treat me if a serious problem occurred?
- 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?
Informed Consent for Cosmetic Surgery
Signing paperwork alone does not create true informed consent. It should be a continuing conversation that allows the patient to decide freely after receiving adequate information.
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. Any complication that could significantly affect the patient's medical condition, employment, lifestyle, or priorities should receive special attention.
No one should be pushed into signing a surgical consent form quickly. Ask for clarification when a term or complication is unclear. It can be helpful to take notes, bring a trusted person to the consultation, and review written instructions at home.
When to Seek Help After Cosmetic Surgery
The surgeon's office should explain which symptoms require attention and copyright the appropriate provider. The surgical team should be contacted quickly if symptoms become worse, appear unusual, or do not match the expected healing process.
Potential emergency signs after cosmetic surgery include:
- Breathing problems, chest discomfort, bloody coughing, or fainting
- Unexpected pain, swelling, redness, or heat affecting one leg
- Significant bleeding or swelling that expands quickly
- Intense pain that does not improve after taking the recommended medicine
- High fever, chills, spreading redness, or pus-like drainage
- Mental confusion, severe weakness, or unusual inability to remain alert
- 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. 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. 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. 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.
Anyone travelling outside Canada for cosmetic surgery should arrange appropriate postoperative care before coming home. A lower initial price may not include management of infection, wound problems, blood clots, implant complications, or revision surgery.
Weighing Cosmetic Surgery Benefits Against Risks
Patients should consider surgery only when their goals are achievable, their health is suitable, and they understand the risks and recovery. An appropriate candidate understands that cosmetic surgery may create improvement without producing perfection.
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. Recommending against surgery can be a sign of careful and ethical medical practice.
How to Make an Informed Cosmetic Surgery 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.
Before surgery, research the operation, assess your health risks, verify medical credentials, ask thorough questions, and prepare for the complete healing period. A complete understanding of the likely improvements, procedure limitations, available options, and associated risks helps patients determine whether cosmetic surgery is appropriate for them.
