Background: Vitamin D deficiency is a significant public health concern in India, particularly during pregnancy, where it can lead to complications such as osteomalacia.
Case presentation: This case report highlights a rare instance of severe osteomalacia in a 21-year-old primigravida at 12 weeks of gestation, who presented with seizures, generalized body pain, spasms in her upper limbs, and proximal muscle weakness. Laboratory results revealed critically low vitamin D levels (3 ng/mL), elevated parathyroid hormone (PTH) levels, and hypocalcemia, confirming osteomalacia as the cause.
Results: She was treated with high-dose vitamin D and calcium supplementation, resulting in marked improvement within three days.
Conclusion: This case highlights the importance of recognizing and treating vitamin D deficiency in pregnant women in India, where it remains an underdiagnosed and underappreciated issue.
