Is It Spina Bifida? Why the Spine Didn't Close & Expert Medical Next Steps

If you've been told that your baby—or even you—may have spina bifida, it's natural to have questions. What does it mean? Why didn't the spine close properly? And what should happen next?

This guide explains what spina bifida is, why it happens, and what medical experts recommend for diagnosis and treatment. The goal is to give you clear, reliable information without causing unnecessary fear—while still being honest about the condition and the importance of medical care.

What Is Spina Bifida?

Spina bifida is a birth condition that affects the spine and spinal cord. It happens when the neural tube—the structure that eventually becomes the brain and spinal cord—doesn't close completely during early pregnancy.

The neural tube normally closes within the first 28 days after conception, often before someone even knows they are pregnant. If it doesn't close fully, a gap remains in the spine.

The severity of spina bifida varies widely. Some people have very mild forms and may not even know they have it. Others may have more serious complications that require surgery and lifelong care.

Types of Spina Bifida

There are three main types:

1. Spina Bifida Occulta (Mildest Form)

• "Occulta" means hidden.
• The spinal cord and nerves are usually normal.
• There may be a small gap in one or more vertebrae.
• Often discovered accidentally on an X-ray.
• Most people have no symptoms.

2. Meningocele (Moderate Form)

• A fluid-filled sac pushes through an opening in the spine.
• The spinal cord usually stays in place.
• Surgery may be needed.
• Nerve damage is less common than in severe forms.

3. Myelomeningocele (Most Severe Form)

• The spinal cord and nerves develop outside the body in a sac.
• Nerve damage is common.
• Can cause weakness or paralysis in the legs.
• May affect bladder and bowel control.
• Often linked with hydrocephalus (fluid buildup in the brain).

When most people refer to spina bifida, they mean myelomeningocele.

Why Didn't the Spine Close?

Spina bifida is a neural tube defect. The exact cause isn't always known, but research shows it's likely due to a mix of genetic and environmental factors.

Here are the most common risk factors:

1. Low Folic Acid

Folic acid (vitamin B9) is critical in early pregnancy. A deficiency significantly increases the risk of spina bifida.

Health authorities recommend:

• 400–800 micrograms daily for people who could become pregnant.
• Higher doses (under medical supervision) if there's a history of neural tube defects.

2. Genetic Factors

• Having a family history of neural tube defects increases risk.
• Most cases, however, occur without any family history.

3. Maternal Health Conditions

• Diabetes (especially if not well-controlled)
• Obesity
• Certain autoimmune conditions

4. Medications

Some anti-seizure medications (like valproic acid) are linked to higher risk.

5. High Body Temperature in Early Pregnancy

• High fevers
• Prolonged hot tub or sauna use

It's important to understand: spina bifida is not caused by something you intentionally did wrong. In many cases, it happens despite doing everything "right."

Signs and Symptoms of Spina Bifida

Symptoms depend on the type and severity.

Possible signs include:

• A visible sac or lump on a newborn's back
• Weakness or paralysis in the legs
• Loss of bladder or bowel control
• Foot deformities
• Scoliosis
• Head enlargement (from hydrocephalus)

Mild spina bifida occulta may show:

• A small dimple on the lower back
• A patch of hair
• A birthmark over the spine

If you notice any of these signs, medical evaluation is essential.

How Is Spina Bifida Diagnosed?

During Pregnancy

Doctors may detect spina bifida through:

• Maternal blood test (AFP test)
• Ultrasound
• Fetal MRI (in some cases)

After Birth

Diagnosis may include:

• Physical exam
• MRI
• CT scan
• Ultrasound (for infants)

Early diagnosis allows for faster treatment planning.

Expert Medical Next Steps

If spina bifida is diagnosed or strongly suspected, here's what typically happens:

1. Immediate Specialist Referral

You may be referred to:

• A pediatric neurosurgeon
• A maternal-fetal medicine specialist
• A neurologist
• A urologist
• An orthopedic specialist

2. Surgery

For myelomeningocele:

• Surgery is usually performed within 24–48 hours after birth.
• In some cases, fetal surgery may be offered before birth.

Surgery helps:

• Protect exposed nerves
• Reduce infection risk
• Prevent further nerve damage

It does not reverse nerve damage that has already occurred.

3. Hydrocephalus Management

If fluid builds up in the brain:

• A shunt may be placed to drain excess fluid.
• Regular monitoring is needed.

4. Long-Term Care

Spina bifida is often a lifelong condition. Care may include:

• Physical therapy
• Mobility aids (braces, wheelchair)
• Bladder and bowel management programs
• Ongoing monitoring for complications

With modern treatment, many people with spina bifida live full, productive lives.

Could It Be Something Else?

Sometimes, spinal abnormalities may raise concern for other bone or mineral conditions.

For example, weakened bones from vitamin D deficiency can affect skeletal development and cause bone deformities in children. If you're concerned about bone softening or skeletal issues related to vitamin deficiency, use this free Osteomalacia / Rickets symptom checker to help determine whether low vitamin D or mineral imbalance could be affecting bone health.

This is not a replacement for medical care—but it may help guide your next conversation with a healthcare professional.

When to Seek Immediate Medical Care

Spina bifida can be serious. Seek urgent medical attention if:

• A newborn has an open spinal lesion
• There are signs of infection (fever, redness, swelling)
• A baby's head is rapidly enlarging
• There is sudden weakness or loss of bladder control
• Severe back pain with neurological symptoms occurs

These can be signs of complications that need immediate evaluation.

Always speak to a doctor right away if you think something could be life-threatening or serious.

---

Can Spina Bifida Be Prevented?

Not all cases are preventable. However, risk can be reduced by:

• Taking folic acid daily before and during early pregnancy
• Managing diabetes carefully
• Reviewing medications with a doctor before pregnancy
• Avoiding overheating in early pregnancy
• Maintaining a healthy weight

If you've had one child with spina bifida, a doctor may recommend a higher folic acid dose before future pregnancies.

---

What Is the Outlook?

The outlook for spina bifida depends on severity.

• Spina bifida occulta: Often no impact on life expectancy.
• Meningocele: Many children recover well after surgery.
• Myelomeningocele: Requires lifelong care, but survival and quality of life have improved dramatically due to advances in surgery and rehabilitation.

Many individuals with spina bifida:

• Attend school
• Work
• Have relationships and families
• Live independent lives

Early intervention and coordinated care make a significant difference.

The Bottom Line

Spina bifida happens when the spine doesn't close completely during early pregnancy. The reasons often involve a combination of genetics, folic acid levels, and maternal health factors. It is not typically caused by one simple mistake.

If you suspect spina bifida—or have received a diagnosis—the next step is clear: get expert medical guidance immediately. Early evaluation, imaging, and specialist referral can improve outcomes and reduce complications.

While information online can help you understand what's happening, it cannot replace a personalized medical assessment. If anything seems urgent, worsening, or life-threatening, speak to a doctor or seek emergency care right away.

Knowledge is powerful—but the right medical team is essential.
