Spina bifida is a complex yet manageable condition that affects the spine and nervous system. It occurs when the spinal column does not close completely during early fetal development. While the term might sound intimidating, understanding its causes, types, and treatment options can help individuals and families make informed choices about care and quality of life.
This article offers a clear and accessible overview of spina bifida, including its major forms, potential causes, common symptoms, and available care strategies — all explained in simple, professional language.
What Is Spina Bifida?
Understanding Spina Bifida begins with knowing that it is a neural tube defect (NTD) a condition that develops during the first few weeks of pregnancy. The neural tube is the structure that eventually forms the baby’s brain, spinal cord, and surrounding tissues. When this tube fails to close properly, a small gap or opening remains in the spinal column, leading to varying degrees of spinal and nerve involvement.
The severity of spina bifida can vary widely. Some people may have mild symptoms or even go undiagnosed for years, while others may experience significant physical challenges that require lifelong care. Advances in medical treatment, surgery, and physical therapy have greatly improved outcomes for individuals living with this condition.
Types of Spina Bifida
There are three main types of spina bifida, each with distinct characteristics and levels of severity.
- Spina Bifida Occulta
This is the mildest and most common form. In spina bifida occulta, there’s a small gap in one or more vertebrae, but the spinal cord and nerves usually remain unaffected. Most people with this type have no visible signs or symptoms and may not even realize they have it until it’s discovered during an imaging test for another condition.
Common signs (if any) may include:
- A small patch of hair, dimple, or birthmark on the lower back
- Mild back pain or weakness (in rare cases)
- Meningocele
In this type, a sac of fluid pushes through the spinal opening, but it doesn’t contain the spinal cord or nerves. Meningocele can often be repaired with surgery, and many people experience little to no long-term nerve damage. It’s less common than other forms and typically detected at birth.
- Myelomeningocele
This is the most severe form of spina bifida. In myelomeningocele, both the spinal cord and its protective coverings protrude through the opening in the spine, forming a visible sac on the baby’s back. It can lead to nerve damage, muscle weakness, paralysis, and loss of bladder or bowel control.
Treatment usually involves surgery soon after birth — or even during pregnancy — to close the opening and prevent further complications.
Causes and Risk Factors
The exact cause of spina bifida isn’t always clear, but it’s believed to result from a combination of genetic, nutritional, and environmental factors that interfere with normal fetal development.
- Folic Acid Deficiency
One of the most well-known risk factors is a lack of folic acid (vitamin B9) during early pregnancy. Folic acid plays a critical role in the formation of the neural tube, and insufficient intake increases the risk of defects like spina bifida.
- Genetic Factors
A family history of neural tube defects can slightly increase the risk. Certain genetic mutations may affect how the body processes folate, making supplementation especially important for at-risk families.
- Maternal Health Conditions
Conditions such as diabetes, obesity, or uncontrolled fevers during pregnancy may increase the risk of neural tube defects.
- Medications and Environmental Influences
Some medications — particularly those used for epilepsy or acne — can interfere with folate metabolism. Exposure to high temperatures, radiation, or specific toxins early in pregnancy can also contribute to risk.

Symptoms of Spina Bifida
The symptoms depend on the type and severity of the defect:
- Mild cases (like occulta) may show no visible symptoms.
- Moderate to severe cases can include:
- Weakness or paralysis in the legs
- Loss of bladder or bowel control
- Orthopedic issues, such as clubfoot or scoliosis
- Hydrocephalus (fluid buildup in the brain)
- Learning difficulties (in some cases)
Regular checkups and early diagnosis are essential for managing these symptoms and improving overall quality of life.
Diagnosis and Prenatal Screening
Spina bifida can often be detected before birth through prenatal tests such as:
- Blood tests (AFP test): Measures alpha-fetoprotein levels in the mother’s blood.
- Ultrasound: Can reveal spinal abnormalities.
- Amniocentesis: Analyzes amniotic fluid for neural tube defect indicators.
Early diagnosis helps families plan for appropriate medical care and delivery support.
Treatment and Care Options
While spina bifida cannot be completely cured, early and ongoing treatment can significantly improve function, independence, and quality of life.
- Surgery
In moderate or severe cases, surgery may be required shortly after birth to close the spinal opening and minimize infection risk.
For myelomeningocele, fetal surgery — performed before birth — is sometimes recommended to repair the spinal defect while the baby is still in the womb. This can reduce nerve damage and improve long-term outcomes.
- Physical and Occupational Therapy
Therapists help strengthen muscles, improve mobility, and teach adaptive skills. This allows children and adults with spina bifida to lead more independent lives.
- Assistive Devices
Braces, crutches, wheelchairs, or walkers can help improve movement and stability. Customized equipment supports daily activities and reduces the risk of falls or strain.
- Ongoing Medical Management
Individuals may require regular checkups with specialists, including neurologists, urologists, and orthopedic doctors, to manage symptoms such as bladder control issues, hydrocephalus, or scoliosis.
- Nutritional Support and Prevention
Taking 400 micrograms of folic acid daily before and during early pregnancy can greatly reduce the risk of spina bifida and other neural tube defects. Foods rich in folate, such as leafy greens, citrus fruits, and fortified cereals, are also beneficial.
Living with Spina Bifida
Advances in medicine, assistive technology, and rehabilitation have enabled many people with spina bifida to lead active, fulfilling lives. Early intervention, a supportive care team, and a positive environment make a significant difference in overall well-being.
Parents and caregivers play a crucial role in ensuring that children receive physical, emotional, and educational support tailored to their unique needs. With proper management and community awareness, individuals with spina bifida can achieve independence and success in many areas of life.
Final Thoughts
Spina bifida is a lifelong condition, but it doesn’t define a person’s potential. At The Web Health, we believe that understanding its types, causes, and care options empowers both families and patients to make informed decisions, access proper treatment, and find the support they need for a healthier, more independent life.
Through early detection, proper treatment, and continuous care, individuals living with spina bifida can lead healthier, more independent, and meaningful lives.
