Patient's question:
My child has just started preschool, but I always feel something is wrong with them. The child has always been deficient in vitamin D and has rickets. Hello, what are the symptoms of vitamin D deficiency and rickets?Doctor's answer:
Bone Changes (1) Infants aged 3-6 months have soft skulls, which can be gently pressed with fingers to feel like a ping pong ball on the occipital part. (2) After 6 months, the child's wrists and ankles become swollen, forming bracelets for the hands and ankles. (3) Infants aged 8-9 months are prone to cranial or saddle-shaped heads. The anterior and posterior fontanelles are reduced or fuse later (normal fusion time is 12-18 months after birth). These teeth are delayed and arranged in reverse.
