What Is Spina Bifida? Symptoms, Causes, and Treatment Methods

Have you ever thought about how delicate the development of the nervous system is during pregnancy? The proper formation of the spinal cord and the structures that protect the brain is vital for a baby’s healthy growth. Spina bifida is a congenital condition that occurs when this process is not completed properly. Early diagnosis and proper follow-up can significantly improve quality of life for individuals with this condition.

What Is Spina Bifida?

Spina bifida is a congenital spinal disorder that occurs when the spinal bones and the membranes surrounding the spinal cord do not fully close. It develops when the structure called the neural tube fails to close properly during the first weeks of pregnancy. This can cause part of the spinal cord to remain exposed or damage the protective membranes.

How Does Spina Bifida Occur?

Around the third week of pregnancy, the neural tube begins to form and normally closes within a few days to create the spinal cord and brain. If this closure process does not occur, the bony structures protecting the spinal cord remain incomplete, resulting in spina bifida. Therefore, this condition develops very early in pregnancy—often before the mother even realizes she is pregnant.

Types of Spina Bifida

Spina bifida can appear in different forms depending on the degree of spinal involvement and the size of the opening. Each form presents distinct clinical findings and requires a specific treatment approach. The three most common types are described below:

• Spina Bifida Occulta: The mildest form. There is a small opening in the spinal bones, but the nerve tissue remains unaffected. Symptoms are usually absent, though some people may have a small dimple, patch of hair, or birthmark on the back. Treatment is generally unnecessary; regular check-ups are sufficient.

• Meningocele: The spinal membranes protrude through an opening in the spine, but the nerve tissue is not included in the sac. A fluid-filled sac may be visible under the skin. Nerve damage is rare. Treatment involves surgically closing the sac to eliminate infection risk.

• Myelomeningocele: The most severe form. Both the spinal membranes and the spinal cord protrude through the opening. Paralysis, leg weakness, and loss of bladder or bowel control may occur. Immediate surgery after birth is required. Long-term rehabilitation, physical therapy, and multidisciplinary follow-up are essential.

Symptoms of Spina Bifida

The symptoms of spina bifida vary depending on the type of the condition and the location of the spinal defect. Occulta is often asymptomatic, while myelomeningocele causes more serious problems.

• Visible signs: A sac, swelling, or opening on the back.

• Neurological symptoms: Leg numbness, loss of reflexes, or muscle weakness.

• Bladder and bowel problems: Urinary incontinence or difficulty controlling stool.

• Orthopedic issues: Scoliosis, hip dislocation, or foot deformities.

• Skin findings: Birthmarks, dimples, or patches of hair on the back.

What Causes Spina Bifida?

The exact cause of spina bifida is not fully understood, but it is believed to result from a combination of genetic and environmental factors. One of the most important risk factors is folic acid deficiency. Insufficient folic acid before and during early pregnancy significantly increases the risk of neural tube defects. Diabetes, obesity, certain epilepsy medications, and a family history of similar conditions also raise the risk.

How Is Spina Bifida Diagnosed?

Spina bifida is often detected through prenatal screening tests. The alpha-fetoprotein (AFP) test, performed on the mother’s blood, may indicate a neural tube defect if levels are elevated. If abnormalities are found, a detailed ultrasound and fetal MRI are used to confirm the diagnosis. After birth, MRI or CT scans help assess the spinal cord and bone structures.

Spina Bifida Treatment Methods

Treatment depends on the type of spina bifida and the extent of spinal cord involvement. Mild cases are monitored through observation, while severe forms require a multidisciplinary approach. Early intervention is crucial. Both surgical and long-term management should be guided by a specialist. You can safely reach certified physicians through the Online Doctor Consultation service offered by Happ Health.

• Surgical Treatment: In severe cases such as myelomeningocele, surgery is performed within the first 48 hours after birth. The spinal cord and membranes are closed to prevent infection and further nerve damage.

• Rehabilitation: After surgery, physical therapy, mobility support, and exercises that strengthen bladder and bowel control are implemented.

• Fetal Surgery: In some centers, prenatal surgery may be performed while the baby is still in the womb. However, this procedure carries risks and should be considered carefully for eligible cases.

How to Prevent Spina Bifida

The most effective preventive measure is folic acid supplementation. Women planning pregnancy should start taking 400 micrograms of folic acid daily at least one month before conception. This can reduce the risk of neural tube defects by up to 70%. Maintaining a balanced diet, managing chronic diseases, and avoiding medication without medical advice are also important preventive steps.

Living with Spina Bifida and Long-Term Follow-Up

Individuals born with spina bifida can lead active lives with early treatment and regular follow-up. Collaboration between physical therapy, neurology, orthopedics, and urology specialists is essential. Regular check-ups help detect complications early and improve overall quality of life.

Advice for Families of Children with Spina Bifida

Families should remain patient and well-informed during their child’s development. Regular home exercises, consistent physical therapy, and emotional support ease adaptation. Collaborating with teachers also enhances social and academic progress.

Supporting not only the child’s physical rehabilitation but also their emotional well-being is essential. Consulting a mental health professional can ease adjustment for both the child and the family. You can access online psychologist support on the Happ Health Psychology page.

Preventive Steps for a Healthy Pregnancy

Expectant mothers should not skip pre-pregnancy check-ups, start folic acid supplementation early, and maintain healthy eating habits. Managing diabetes, obesity, or other chronic conditions before conception is also crucial. Conscious preparation provides the strongest foundation for a healthy pregnancy and baby development.

Regular health check-ups before pregnancy help detect potential risks early. Through the Check-up service, you can assess your overall health status and take the necessary precautions for a safe and healthy pregnancy.
