Question
The baby has sparse hair around the head, and this condition has persisted for some time. Parents are concerned and hope to receive professional medical advice.
Answer
Hello: Sparse hair around a baby’s head can indeed be a symptom of calcium deficiency. It is recommended to first supplement with vitamin D under the guidance of a doctor, usually with an oral dose of 5,000 to 10,000 units per day. For infants with severe rickets or those who often have diarrhea, consider switching to an intravenous vitamin D injection. At the same time, oral calcium tablets should be taken, 0.5 grams each time, one to three times daily, to ensure adequate calcium intake for the baby and to ensure the baby’s safety.
