The shape, proportion, or overall appearance of the face and body can be improved through cosmetic surgery. 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. Before deciding whether a procedure is suitable, it is essential to understand the risks of cosmetic surgery.
A major complication does not occur in most patients, yet a perfect outcome and completely risk-free surgery can never be promised. 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. In other cases, a complication can require drugs, hospital care, another operation, or extended monitoring.
In Canada, patients should be clearly informed about expected benefits, important risks, treatment alternatives, recovery needs, and what may happen if they decline surgery. A careful consultation gives you time to consider this information without pressure. Cosmetic surgery is usually elective, so you should feel comfortable delaying or declining it when the risks outweigh the likely benefits.
What Risks Can Cosmetic Surgery Involve?
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. Normal early healing can involve bruising, swelling, soreness, fatigue, tightness, numbness, and a small amount of drainage. A complication is different. It is an unexpected problem that exceeds routine healing and can require treatment.
Plastic surgery complications may include the following:
- A hematoma, which is a collection of blood, or other excessive bleeding
- An infection in the incision or deeper surgical tissues
- A collection of fluid called a seroma
- Blood clots affecting the legs or lungs
- Delayed wound healing or wound separation
- Noticeable, raised, widened, or uneven scars
- Nerve injury, numbness, or altered sensation
- Tissue damage or loss resulting from inadequate blood flow
- Reactions to anesthesia, medications, adhesives, or surgical materials
- Unevenness, contour irregularities, or an unsatisfactory appearance
- Problems with normal function, including breathing, motion, or sensation
- Additional medical treatment or a revision operation
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
Normal recovery often includes temporary discomfort and changes in appearance or sensation. Knowing what normal healing looks like helps patients recognize when a symptom may be a warning sign.
Postoperative Pain and Tenderness
Pain levels vary by procedure and patient. The surgical site can feel tender, tight, sore, or mildly burning during recovery. As recovery progresses, pain should generally become less intense and easier to control. Patients should quickly report severe or spreading pain, especially when it is accompanied by fever, redness, shortness of breath, or unusual swelling.
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. 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. Residual swelling can change shape, symmetry, and skin texture during recovery.
Changes in Feeling After Surgery
During an operation, small nerves responsible for sensation may be stretched, repositioned, or divided. 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. 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 or Blood Collection
Minor bleeding near a surgical incision can occur during early recovery. When bleeding is more substantial, blood may collect under the skin or in the surgical site and form a hematoma. Possible signs of a hematoma include worsening pain, hard swelling, colour changes, or sudden asymmetry.
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.
Treatment may involve antibiotics, wound care, drainage, or another operation. An infected breast implant or other medical device may need to be removed. Smoking, uncontrolled diabetes, poor nutrition, and problems with blood circulation can raise the risk of infection or make it harder to treat.
Fluid Buildup or Seroma
A seroma develops when a pocket of clear fluid forms under the surgical tissues. 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.
The body may gradually absorb a small seroma without further treatment. 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. A pulmonary embolism can occur if a piece of the clot breaks away and reaches the lungs. 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. Prevention may include early walking, compression devices, support garments, hydration, or blood-thinning medication when appropriate.
Delayed or Difficult Wound Healing
An incision may heal slowly or begin to separate. 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. When a wound is left to close slowly from its deeper layers toward the surface, the process is called healing by secondary intention. Healing in this way often takes more time and can result in a more noticeable scar.
Loss of Tissue From Poor Blood Supply
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 and nicotine use are major preventable risk factors because nicotine narrows blood vessels and reduces oxygen delivery.
The extent of tissue damage determines which treatment is required. Care may require dressings, surgical removal of damaged tissue, skin grafting, reconstruction, or delayed corrective surgery.
Risks Related to Anesthesia
Local anesthesia, sedation, general anesthesia, or a combination may be used during cosmetic surgery. The safest choice depends on the operation, the patient's medical history, the expected length of surgery, and the surgical setting.
Potential complications connected with anesthesia include:
- Feeling sick or vomiting after anesthesia
- Dizziness, mental confusion, or drowsiness that lasts longer than expected
- Headache or sore throat
- Unexpected reactions to anesthetic or other medications
- Abnormal blood pressure or irregular heart rhythm
- Breathing difficulties
- Stomach contents entering the lungs, known as aspiration
- Injury to the teeth, lips, mouth, or airway
- Severe cardiac, respiratory, or neurological problems
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.
Scarring and Changes to the Skin
A surgical procedure that breaks the skin will always leave some degree of scarring. A surgeon may try to conceal incisions in folds, hair-bearing areas, or covered locations, but complete scar elimination is not possible.
Scars often appear red, raised, firm, or darker during early healing. Over 12 months or longer, scar tissue can gradually fade and soften. 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
Hypertrophic scarring causes raised tissue that does not extend beyond the wound edges. Keloid tissue spreads past the edges of the initial incision. Patients should inform their surgeon if they or close family members have developed raised or unusual scars.
Treatment options can include silicone sheets or gels, pressure treatment, corticocopyright injections, laser therapy, and scar revision. Treatment may improve a scar, but it cannot guarantee that abnormal scar tissue will not return.
Changes in Skin Colour and Texture
Surgery can sometimes cause darkening, lightening, redness, visible blood vessels, dimpling, firmness, or changes in skin texture. Some of these changes resolve over time, while others can last permanently. The chance of pigment or texture problems varies according to skin characteristics and surgical technique.
The Risk of an Unwanted Cosmetic Result
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.
Appearance-related problems may include:
- Unevenness that remains after healing
- Visible dents, bulges, or contour differences
- Under-correction or over-correction
- An unnatural or overly tight appearance
- 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 facial rejuvenation cosmetic plastic surgery may benefit from improvement, revision cosmetic surgery can be considered. However, another operation brings new risks. A second operation may be technically harder because previous surgery can leave scar tissue, stiffness, and diminished blood flow.
Before proceeding, patients should understand exactly what is included in the surgeon's or clinic's revision policy. Surgeon fees, facility costs, anesthesia, implants, medications, travel, and time away from work may not all be included in the original price.
Complications by Type of Cosmetic Surgery
General surgical risks apply to many operations, but each procedure also has unique concerns.
Risks of Facelift and Neck Lift Surgery
Hematoma, facial nerve injury, hairline alteration, hair loss around incisions, skin necrosis, contour problems, earlobe changes, loss of feeling, facial weakness, and visible scarring are among the risks of facelift and neck lift surgery. Nicotine use can greatly increase the risk of skin-healing problems.
Rhinoplasty Risks
Rhinoplasty may cause ongoing swelling, nosebleeds, infection, asymmetry, changes in smell, visible contour irregularities, septal perforation, nasal collapse, or difficulty breathing through the nose. It can take at least a year for swelling to resolve enough for the final nasal shape to be assessed. Revision rhinoplasty can be more difficult because of scar tissue and changes to the cartilage.
Eyelid Surgery Risks
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
Nipple sensation, symmetry, scars, and the ability to breastfeed may be affected by breast augmentation, breast lift surgery, or breast reduction. Additional complications can include bleeding beneath the tissue, infection, fat tissue death, slow wound healing, and changes to the nipple or areola location.
Implant-based breast surgery involves long-term risks beyond the normal surgical recovery period. Capsular contracture, rupture, deflation, rippling, displacement, rotation, pain, ongoing imaging, and future surgery may occur with breast implants. 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. Activity and lifting restrictions can remain in place for a number of weeks.
Risks of Fat Transfer
During fat grafting, fat is taken from one body area and placed into a different location. Some of the transferred fat will be absorbed, which can affect volume and symmetry. 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.
Factors That Increase the Risk of Complications
Some health and lifestyle factors can raise the chance of complications. Preoperative preparation may include laboratory testing, medication changes, weight management, stopping nicotine, or obtaining medical clearance.
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
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A bleeding disorder or history of blood clots
- Obesity, unstable weight, or recent major weight loss or gain
- A diagnosed or suspected sleep-related breathing disorder
- Immune system disorders
- Nutritional deficiencies or a low red blood cell count
- Previous radiation or surgery in the treatment 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 and Emotional Risks
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. This temporary low mood is sometimes called postoperative blues.
Significant dissatisfaction is more likely when the expected transformation is not medically achievable. 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. Surgery may not relieve the underlying concern. A psychological evaluation or professional support may be recommended before surgery when concerns are identified.
How to Reduce the Risks of Cosmetic Surgery
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.
- Check the doctor's licence, registration, and professional standing with the applicable provincial or territorial medical regulator.
- 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.
- Follow instructions about fasting, medication changes, testing, and stopping nicotine.
- When needed, organize transportation and early postoperative support from a responsible adult.
- Understand the recovery timeline before booking work, travel, exercise, or major events.
- Attend all follow-up appointments and report unusual symptoms promptly.
- 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.
Finding a Qualified Canadian Cosmetic Surgeon
Each Canadian province and territory is responsible for regulating doctors within its jurisdiction. Patients may verify a physician's licence and registered specialty through the online register maintained by their provincial or territorial regulator.
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 frequently is this specific procedure performed in your practice?
- 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?
- Which medical professional will administer and monitor my anesthesia?
- Who should I contact if I experience a complication outside normal clinic 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?
Informed Consent for Cosmetic Surgery
Informed consent involves more than placing a signature on a document. 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. 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. 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.
Postoperative Warning Signs
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.
Symptoms that may require urgent care include:
- Chest pain, shortness of breath, coughing blood, or fainting
- Unexpected pain, swelling, redness, or heat affecting one leg
- Uncontrolled bleeding or a sudden increase in swelling
- Intense pain that does not improve after taking the recommended medicine
- A significant fever, shaking chills, expanding redness, or thick discharge
- Disorientation, marked weakness, or excessive drowsiness
- Possible tissue damage shown by abnormal colour, blistering, or low skin temperature
- 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
Procedures performed only to change appearance are generally not covered by provincial or territorial health insurance. 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. Extra costs may arise from transportation, hotels, private nursing, lost income, family care, and corrective procedures.
Anyone travelling outside Canada for cosmetic surgery should arrange appropriate postoperative care before coming home. An inexpensive overseas package may exclude the cost of treating infection, poor healing, DVT, implant problems, and corrective operations.
Weighing Cosmetic Surgery Benefits Against Risks
The decision to have cosmetic surgery should be based on realistic goals, good health, informed consent, and a clear understanding of recovery. 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. The decision should account for recovery restrictions, permanent scarring, employment absence, and the possibility that the final result may fall short of expectations.
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.
Making an Informed Decision
Understanding the risks of cosmetic surgery does not mean assuming that complications will occur. The goal is to make a careful choice based on medical information, not promotional claims, social media influence, or the lowest price.
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.
