What Causes Scoliosis?

One of the first questions almost everyone asks after a scoliosis diagnosis is:

Why did this happen?

It's a completely natural question.

In fact, it's one of the most common questions doctors hear.

You find out you have a curve in your spine and immediately want to know why.

What caused it?

Did I do something wrong?

Was it my posture?

My backpack?

The way I sit?

The sports I play?

Something I should have noticed sooner?

People naturally look for explanations.

We want things to make sense.

We want there to be a clear reason.

The problem is that scoliosis doesn't always provide one.

In fact, for most teens diagnosed with scoliosis, the exact cause is unknown.

That may sound surprising.

After all, modern medicine knows a lot about the human body.

But scoliosis is more complicated than many people realize.

The most common type of scoliosis is called adolescent idiopathic scoliosis.

Let's break that name down.

"Adolescent" refers to the age group.

It means the scoliosis developed during the growing years.

"Idiopathic" means the exact cause is unknown.

In other words, doctors know the condition exists.

They know how to diagnose it.

They know how to monitor it.

They know how to treat it.

But they do not know exactly why it develops in most cases.

For many newly diagnosed teens, this answer feels frustrating.

People want certainty.

They want a clear explanation.

They want someone to point to one specific cause.

Unfortunately, scoliosis usually isn't that simple.

One thing that is important to understand is what doesn't cause scoliosis.

Let's start there.

Poor posture does not cause scoliosis.

This is one of the biggest myths people believe.

Many teens spend years hearing:

"Sit up straight."

"Stop slouching."

"Fix your posture."

Then they receive a scoliosis diagnosis and immediately assume the two are connected.

They're not.

Poor posture and scoliosis are different things.

Poor posture can affect how someone sits or stands.

Scoliosis is a structural curve in the spine.

The two are not the same.

Another common myth is that backpacks cause scoliosis.

Many people have heard warnings about carrying heavy backpacks.

As a result, some teens assume their backpack created the curve.

There is no evidence that carrying a backpack causes adolescent idiopathic scoliosis.

Backpacks may cause temporary discomfort or soreness.

They do not create scoliosis.

The same is true for sleeping positions.

Some people wonder:

Did I sleep wrong?

Could my mattress have caused this?

The answer is no.

Sleeping position does not cause scoliosis.

Another common concern involves sports.

Athletes sometimes wonder whether their activities caused the condition.

Did gymnastics cause it?

Dance?

Cheerleading?

Swimming?

Soccer?

Again, scoliosis develops in athletes and non-athletes alike.

There is no evidence that participating in sports causes adolescent idiopathic scoliosis.

Many active, healthy teens develop scoliosis.

Many inactive teens develop scoliosis.

The condition appears across a wide variety of lifestyles.

This is one reason self-blame is so unhelpful.

Most of the things people blame themselves for are not the cause.

Another question people often ask is:

Is scoliosis genetic?

The answer is complicated.

Researchers believe genetics likely play a role in many cases of adolescent idiopathic scoliosis.

Scoliosis sometimes appears in families.

You may have a parent, grandparent, sibling, aunt, uncle, or cousin who also has scoliosis.

But genetics alone do not explain everything.

Not everyone with a family history develops scoliosis.

And many people with scoliosis have no known family history at all.

This is one reason researchers continue studying the condition.

The story is more complicated than a single gene.

Another thing researchers know is that scoliosis is relatively common.

Millions of people around the world have it.

And because it is so common, scientists have spent decades studying it.

Researchers continue investigating factors involving growth, genetics, hormones, nervous system development, and other biological processes.

The good news is that understanding continues to improve.

The challenge is that there still isn't one simple answer.

Many newly diagnosed teens struggle with this uncertainty.

They think:

If doctors don't know the cause, how can they help me?

That's a reasonable question.

The answer is that understanding the exact cause and understanding how to manage a condition are two different things.

Think about headaches.

People can often treat headaches effectively even when they don't know the exact reason a particular headache happened.

The same principle applies here.

Doctors know how to diagnose scoliosis.

Monitor scoliosis.

Measure scoliosis.

And manage scoliosis.

Even though the exact cause remains unclear in many cases.

Another misconception is that scoliosis happens because someone wasn't healthy enough.

That's not true.

Scoliosis develops in healthy people.

Athletic people.

Strong people.

Active people.

People who seem to be doing everything right.

A diagnosis is not evidence that you failed.

It's not evidence that your body failed.

It's not evidence that someone made a mistake.

It's simply a medical condition that develops in some people.

One thing many teens find helpful is understanding that not knowing the cause does not mean the diagnosis is mysterious or dangerous.

Sometimes people hear "unknown cause" and assume something must be wrong.

That's not what doctors mean.

They simply mean that researchers have not identified one specific explanation that applies to most cases.

Medicine contains many conditions that are not fully understood.

That doesn't stop doctors from helping people.

Another important thing to remember is that the cause of scoliosis does not determine your worth.

Many teens spend a lot of energy searching for a reason.

Trying to figure out why it happened.

Trying to identify what they did wrong.

The truth is that even if you knew the exact cause, it wouldn't change who you are.

It wouldn't change your value.

It wouldn't change your future.

And it certainly wouldn't mean you did something wrong.

You did not choose scoliosis.

You did not create scoliosis.

And you do not deserve blame for scoliosis.

Sometimes difficult things happen without clear explanations.

That can be frustrating.

But it is also part of life.

One of the healthiest shifts many people make is moving from:

Why did this happen?

To:

What do I do now?

Because while the cause may remain uncertain, your future still exists.

Your choices still matter.

Your goals still matter.

Your life still matters.

The diagnosis is one part of your story.

Not the entire story.

If you only remember one thing from this article, remember this:

For most teens, the exact cause of scoliosis is unknown.

It is not caused by bad posture.

It is not caused by backpacks.

It is not caused by sleeping positions.

It is not caused by something you did wrong.

Researchers continue studying why scoliosis develops, but one thing is already clear:

Your diagnosis is not your fault.

And understanding that can be one of the most important lessons of all.
