What are the most common complications in surgery and why do they occur?

When someone thinks of plastic surgery, they usually imagine two extreme scenarios:

Either everything goes perfectly.
Or something goes very wrong.

The reality, as almost always, lies in the middle ground.

Complications exist, but not all are serious or unpredictable. Many are known, preventable, and manageable when the process is well-structured and the patient is well-informed.

Understanding them is not to generate fear,
but to make more conscious decisions.


First, an important clarification

A complication does not always mean a mistake or a bad surgery.

In many cases, it is a body's response to a surgical process.

Each organism reacts differently,
which is why it's crucial to talk about probabilities, not absolute certainties.


1️⃣ Prolonged inflammation

It is one of the most common situations.

Why does it happen?

The body needs time to heal.
Tissues are manipulated.
There is fluid retention.

In some people, inflammation lasts longer than expected, especially if:

Rest times are not respected.
Postoperative instructions are not followed.
The body has a more intense inflammatory response.

👉 It's usually not serious, but requires follow-up.


2️⃣ Extensive hematomas or bruises

They appear frequently and cause visual concern, although they do not always represent a serious problem.

Why can they occur?

Capillary fragility.
Tissue mobilization.
Early physical activity.
Unreported medications or supplements.

Most reabsorb over time, but they should be evaluated to rule out other causes.


3️⃣ Infections

They are less frequent, but important to monitor.

Why can they occur?

Lack of adequate hygiene.
Improper wound handling.
Not following care regimens.
Patient's own factors.

Therefore, control, cleaning, and follow-up are essential.


4️⃣ Seromas (fluid accumulation)

It is the accumulation of fluid in the operated area.

Why do they occur?

Spaces created during surgery.
Excessive movement in the postoperative period.
Incorrect use of compression garments or binders.

They are usually not serious, but they must be drained and monitored to avoid discomfort or infections.


5️⃣ Slow or irregular scarring

Not all scars evolve in the same way.

Why does it happen?

Skin type.
Genetic factors.
Smoking.
Early sun exposure.
Lack of specific care.

Therefore, scar care is not optional; it is part of the final result.


6️⃣ Asymmetries or results different from what was expected

It is not always a medical complication, but it is one of the main causes of dissatisfaction.

Why can they occur?

Unrealistic expectations.
Natural body differences.
Inflammation still present.
Lack of time to see the final result.

Many results are not definitively evaluated until several months later.


The most influential factor: the complete process

From experience in consulting, one thing is clear:

Complications do not depend solely on the operating room.

They are directly influenced by:

The prior assessment.
The information the patient receives.
Compliance with postoperative care.
Support and follow-up.

When any of these points fail, the probability of complications increases.


Information is not the same as alarm

Talking about complications is not being negative.
It's being responsible.

People who understand what can happen:

React with less anxiety.
Consult on time.
Follow instructions better.
Live the process with more peace of mind.

And that, paradoxically, reduces risks.


The role of responsible advice

Good advice does not promise "zero complications."

It promises:

Clear information.
Realistic expectations.
Support.
Guidance when something doesn't feel normal.

And that makes a big difference in the patient's experience.


Conclusion

The most frequent complications in surgery are usually known, manageable, and in many cases, preventable.

The key is not to avoid them at all costs, but to:

👉 Choose well
👉 Be informed
👉 Follow instructions
👉 Not go through the process alone

A well-supported surgery does not eliminate all risks,
but it reduces uncertainty and improves the experience.
