Question
Why might a 7-month-old baby shiver without a fever or other apparent cause?
Answer
During infancy, mild calcium deficiency can lead to discomfort in the nervous system, such as irritability, moodiness, excessive sweating, and restless sleep. These symptoms may be early signs of calcium deficiency. If the deficiency is more severe, it may cause symptoms like seizures and muscle weakness, and could also affect bone development, leading to delayed closure of the fontanelle, late teething, delayed time for standing and walking, and even skeletal deformities like pigeon chest and knock knees. Long-term calcium deficiency may also result in skeletal deformities such as chest deformity and leg deformity. To ensure the healthy growth of your baby, it is recommended to consult a doctor promptly and follow medical advice to supplement calcium and vitamin D.
