Vitamin D deficiency isn’t just about weak bones—it can trigger life-threatening seizures in infants. A recent case revealed by pediatrician Dr. Sanchi Rastogi shows how a seven-month-old baby experienced sudden fits due to severe vitamin D deficiency. Here’s everything parents need to know in a simple, listicle format.


1. The Startling Case: Seizures in a Healthy Baby

Dr. Rastogi shared that the baby, previously healthy and active, suddenly began experiencing violent fits while playing. The mother noticed:

The baby rolled back their eyes.

Limbs tightened and shook uncontrollably.

The child lost consciousness after each episode.

The baby had not received any vitamin supplements, and the mother had stopped taking calcium after childbirth.


2. vitamin D Deficiency: A Silent Culprit

Vitamin D is essential for:

Maintaining calcium and phosphorus balance in the blood.

Building and maintaining strong bones and teeth.

Supporting healthy muscle and tissue function.

A severe deficiency can reduce calcium absorption in the intestines, leading to hypocalcemia, which in turn can trigger muscle cramps, weakness, fatigue, and in extreme cases, seizures.


3. How the Diagnosis Was Confirmed

Dr. Rastogi treated the infant with Vitamin B6, after which EEG patterns improved. This helped confirm the underlying vitamin D deficiency. Early recognition of such symptoms is crucial to prevent long-term complications in infants.


4. Why Infants Are Vulnerable

Several factors can make babies susceptible to vitamin D deficiency:

Lack of sunlight exposure, especially in newborns who spend most of their time indoors.

Mothers not taking enough calcium or vitamin D supplements during pregnancy and lactation.

Poor dietary intake of vitamin D-rich foods.

Babies need vitamin D to grow strong bones, develop healthy teeth, and prevent conditions like rickets and seizures.


5. Common Causes of vitamin D Deficiency

Beyond sunlight and diet, other factors include:

Medical conditions affecting vitamin absorption.

Weight-loss surgeries in mothers or children.

Certain medications interfering with vitamin metabolism.

Biological factors like skin melanin levels and age.

Parents should be aware of these risks, especially if their child shows unusual muscle weakness or sudden episodes of seizures.


6. How to Treat vitamin D Deficiency

Treatment and prevention focus on maintaining adequate vitamin D levels:

Dietary intake: Include foods rich in vitamin D, such as fortified milk, egg yolks, and fatty fish.

Sunlight: Moderate exposure helps the body produce natural vitamin D.

Supplements: Available in two forms:

Vitamin D2: Plant-based, requires a prescription.

Vitamin D3: Animal-based, easily absorbed, available over-the-counter.

Consult a pediatrician to determine the correct dosage for your child.


7. Key Takeaways for Parents

Vitamin D deficiency can be silent yet dangerous, even in otherwise healthy babies.

Symptoms to watch for: seizures, limb twitching, muscle cramps, and unusual fatigue.

Early supplementation, sunlight exposure, and a balanced diet can prevent severe consequences.

Always consult a doctor before starting vitamin D supplements for your infant.


Final Word

The case shared by Dr. Rastogi is a wake-up call for parents. vitamin D isn’t just about bone health—it’s essential for neurological and muscular stability in babies. Awareness and timely intervention can save lives and prevent serious complications.
