Vitamin D deficiency in children is a common condition where the body lacks sufficient vitamin D, which is essential for bone health, immune function, and overall development. Symptoms of vitamin D deficiency can include bone pain, muscle weakness, frequent infections, delayed growth, and in severe cases, rickets, which leads to soft and weak bones. Treatment typically involves vitamin D supplementation, along with dietary changes and increased sun exposure to help the body absorb more vitamin D. The benefits of treatment include stronger bones, improved immune function, and better overall health. The duration of treatment depends on the severity of the deficiency and the child’s response to supplementation, but it generally takes a few months to correct the levels. Dr. Manpreet Sethi, a pediatric endocrinologist, specializes in managing vitamin D deficiency in children. She provides tailored treatment plans and ensures proper monitoring of vitamin D levels to promote optimal growth and development in her patients.
