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. 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.
Most patients recover without a major complication, but no surgeon can promise a perfect result or a risk-free operation. Complications may result from anesthetic medication, bleeding, infection, delayed healing, unexpected reactions, or an individual response to surgery. Some complications are temporary and easy to treat. Others may require medication, hospital care, revision surgery, or long-term follow-up.
Canadian patients should receive understandable information about benefits, material risks, available alternatives, recovery demands, and the possible effects of choosing no treatment. During a careful consultation, patients should be able to consider the facts without being rushed. 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?
Any undesirable medical, functional, or cosmetic result connected with an operation may be considered a cosmetic surgery risk. Risk levels vary according to the procedure, surgical method, treatment area, operation length, anesthesia type, and the patient's general health.
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. Expected healing effects and surgical complications are 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
- Infection at the incision or within deeper tissue
- A collection of fluid called a seroma
- Clots that form in a leg vein or travel to the lungs
- Delayed wound healing or wound separation
- Noticeable, raised, widened, or uneven scars
- Nerve injury, numbness, or altered sensation
- Skin, fat, or tissue loss caused by poor blood supply
- Unexpected reactions to anesthetic drugs, medicines, adhesives, or surgical products
- Unevenness, contour irregularities, or an unsatisfactory appearance
- Problems with normal function, including breathing, motion, or sensation
- Additional medical treatment or a revision operation
Although serious complications are rare, they must still be reviewed before surgery. Rare risks may include severe infection, major blood loss, organ injury, heart problems, stroke, pulmonary embolism, permanent disability, or death.
Common Short-Term Effects After Cosmetic Surgery
A degree of discomfort and physical change is expected while the body heals. Knowing what normal healing looks like helps patients recognize when a symptom may be a warning sign.
Soreness After Cosmetic Surgery
Pain levels vary by procedure and patient. Patients may notice aching, tightness, burning, or tenderness around the treated area. Discomfort is normally expected to improve gradually during healing. Pain that suddenly becomes severe, spreads, or occurs with fever, redness, shortness of breath, or unusual swelling should be reported promptly.
Bruising and Tissue Swelling
Swelling is caused by inflammation and fluid moving into the treated tissues. It may hide the initial surgical result for weeks or months. 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.
The outcome of surgery should not be assessed before healing has progressed. During recovery, lingering swelling can make contours, symmetry, and skin texture appear different.
Altered Sensation and Numbness
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
During early recovery, patients may require support with transportation, meals, family duties, pets, household chores, and self-care. Restrictions may apply to driving, physical activity, lifting, swimming, and work. Swelling, bleeding, incision issues, and additional complications may become more likely when recovery limits are ignored.
Potential Surgical Complications
Postoperative 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. A hematoma may cause increasing pain, firmness, swelling, discolouration, or a sudden difference between two sides of the body.
Some hematomas can be observed, while others must be drained. In certain cases, the patient may need to return to the operating room.
Infection
The incision, nearby skin, deeper surgical tissues, or an implant pocket can become infected. Warning signs can include spreading redness, heat, swelling, worsening pain, pus-like fluid, fever, chills, or an unusual odour.
Treatment may involve antibiotics, wound care, drainage, or another operation. An infected breast implant or other medical device may need to be removed. Patients who smoke or have uncontrolled diabetes, nutritional problems, or poor blood flow may face a higher infection risk and slower recovery.
Seroma
A seroma develops when a pocket of clear fluid forms under the surgical tissues. 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
A blood clot that forms in a deep vein, commonly within the leg, is called deep vein thrombosis, or DVT. 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. 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.
Treatment for a wound complication can include specialized dressings, antibiotic medication, removal of unhealthy tissue, or another operation. Healing by secondary intention means allowing an open area to close gradually from the inside outward. The recovery period may be extended, and the final scar may be more prominent.
Skin or Tissue Necrosis
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. 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. Choosing an anesthesia method requires consideration of the operation, medical background, expected surgical time, and facility.
Potential complications connected with anesthesia include:
- Nausea and 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
- Breathing difficulties
- Aspiration, which occurs when material from the stomach reaches the lungs
- Damage to teeth, lips, or the airway
- Severe cardiac, respiratory, or neurological problems
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. Leaving out information can make anesthesia and surgery less safe.
Scarring and Changes to the Skin
Whenever an incision is made through the skin, a scar will form. 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. 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 and Keloid Scarring
A scar that grows thick and elevated while remaining inside the original incision is called a hypertrophic scar. 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.
Possible treatments include silicone products, pressure therapy, copyright injections, laser treatment, or scar revision. Scar treatment may improve texture and appearance, but it cannot ensure that a hypertrophic scar or keloid will never come back.
Changes in Skin Colour and Texture
The treated skin may develop colour changes, redness, noticeable blood vessels, dimpling, firmness, or textural differences. These effects may be temporary or permanent. A patient's skin tone and the procedure being performed can influence the likelihood of these changes.
The Risk of an Unwanted Cosmetic Result
Even when surgery is performed correctly, the final appearance may not match the patient's expectations. Healing is affected by anatomy, skin elasticity, age, previous surgery, scar formation, and natural differences between the two sides of the body.
Possible aesthetic concerns include:
- Ongoing asymmetry
- Visible dents, bulges, or contour differences
- Too little or too much correction
- A result that appears unnatural or excessively tight
- Changes in shape as swelling settles
- Implant position problems
- Visible or poorly placed scars
- Recurrence of sagging or tissue laxity over time
- Dissatisfaction despite an acceptable medical result
Photos, digital simulations, and before-and-after galleries can support discussion, but they cannot guarantee an identical outcome. Every patient's tissues, proportions, and recovery process are unique.
Revision Cosmetic Surgery
A corrective operation may be discussed if a complication develops or if the original result could be refined. 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. Additional costs for the surgeon, operating room, anesthetic, implants, medicine, transportation, accommodation, and missed employment may fall outside the initial price.
Procedure-Specific Cosmetic Surgery Risks
General risks are present across cosmetic surgery, while individual procedures introduce additional concerns.
Facelift and Neck Lift Risks
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.
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. 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.
Blepharoplasty Risks
After blepharoplasty, patients may develop dry eyes, irritation, blurred vision, trouble shutting the eyelids, lid malposition, asymmetry, scarring, orbital bleeding, or changes in eyesight. Immediate medical evaluation is needed for intense eye pain or a sudden visual disturbance.
Risks of Cosmetic Breast Surgery
Procedures such as breast augmentation, mastopexy, and breast reduction can change nipple feeling, breast balance, scarring, and future breastfeeding ability. Additional complications can include bleeding beneath the tissue, infection, fat tissue death, slow wound healing, and changes to the nipple or areola location.
Breast implants bring added long-term considerations. Long-term implant issues can include hard scar tissue, rupture, loss of volume, visible rippling, shifting, rotation, discomfort, and additional procedures. Patients should not assume that breast implants will remain in place permanently without further care. 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 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. The physical strain and recovery requirements may rise when large fat volumes are removed or multiple areas are treated.
Tummy Tuck and Body Lift Risks
Abdominoplasty and body lift surgery involve large incisions and wide areas of tissue movement. Risks include seroma, blood clots, infection, skin loss, wound separation, numbness, prominent scarring, and changes to the position or shape of the belly button. Activity and lifting restrictions can remain in place for a number of weeks.
Possible Fat Grafting Complications
Fat transfer uses liposuction to collect fat, which is then injected into another part of the face or body. The body naturally absorbs some transferred fat, potentially reducing volume or creating asymmetry. Additional complications include dead fat tissue, cysts, calcification, infection, oil cysts, and fat entering a blood vessel. Fat transfer risks vary according to whether the treatment area is the face, breast, buttocks, or another body region.
Who May Face Greater Cosmetic Surgery Risks?
Certain medical conditions and lifestyle habits increase surgical risk. A patient may need medical testing, treatment changes, weight management, nicotine cessation, or clearance from another health professional before surgery.
The likelihood of complications may increase with:
- Cigarette smoking, vaping, or any form of nicotine use
- Diabetes that is not well controlled
- Disease affecting the heart, lungs, kidneys, liver, or circulation
- A bleeding disorder or history of blood clots
- Obesity or major weight changes
- 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
- Drugs, vitamins, or supplements that interfere with clotting or tissue repair
- Mental health concerns or unrealistic goals that interfere with informed decision-making
The presence of one or more risk factors does not automatically prevent cosmetic surgery. Instead, the surgeon must assess whether surgery is reasonably safe and determine what preparation is required.
Psychological and Emotional Risks
An operation performed for appearance can influence a patient's mental and emotional state in addition to the body. 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.
Ways to Lower Cosmetic Surgery Risks
Risk cannot be removed completely, but careful planning can make cosmetic surgery safer.
- Select a qualified doctor who has appropriate education and substantial experience performing the procedure.
- 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.
- Disclose your entire health history, including previous surgery, allergies, medications, supplements, alcohol, cannabis, and nicotine use.
- 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.
- Do not schedule travel, work duties, exercise, or major events until you understand how long recovery may take.
- Follow-up care should not be skipped, and abnormal changes should be reported without delay.
- 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
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. While certification matters, patients should also assess procedure-specific experience, communication, the quality of the facility, aftercare, and the surgeon's approach to complications.
During the consultation, patients may wish to ask:
- What training and certification do you have?
- How frequently is this specific procedure performed in your practice?
- Am I a suitable candidate based on my health and anatomy?
- What complications are seen most frequently with this procedure in your practice?
- 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?
- Which hospital or emergency facility would treat me if a serious problem occurred?
- What follow-up visits are included?
- What costs could arise if I need treatment or revision surgery?
Informed Consent for Cosmetic Surgery
Signing paperwork alone does not create true informed consent. 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. 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. Contact the clinic promptly when symptoms are unexpected, worsening, or different from the recovery plan.
Urgent warning signs may include:
- Breathing problems, chest discomfort, bloody coughing, or fainting
- One-sided leg swelling, tenderness, warmth, or discolouration
- Heavy bleeding or rapidly increasing 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
- A pale, dark, blistered, or unusually cold area of skin
- Sudden vision loss, severe eye pain, or major visual changes
- Ongoing vomiting or difficulty drinking without becoming sick
- Any problem your surgeon specifically described as requiring emergency care
Call 911 or seek emergency care when symptoms may be life-threatening. 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
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.
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. Extra costs may arise from transportation, hotels, private nursing, lost income, family care, and corrective procedures.
Anyone face and body cosmetic surgery 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.
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. A suitable patient recognizes that improvement is possible, but perfection is not.
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.
A responsible surgeon may decline surgery if the patient's risk level is unacceptable, the likely improvement is minimal, or the desired result is unrealistic. This is an important part of responsible care.
How to Make an Informed Cosmetic Surgery Decision
Learning about cosmetic surgery risks does not mean expecting that something will go wrong. Instead, risk awareness allows patients to decide using reliable facts rather than marketing, online trends, or cost as the only factor.
Learn about the procedure, review your personal risk factors, confirm the surgeon's qualifications, ask detailed questions, and plan for a full recovery. When the benefits, limits, alternatives, and possible complications are understood, patients are better prepared to decide whether cosmetic surgery fits their needs.
