Child's active factors or etiology

Patient's question:

Ages of active attention and poor concentration over a year old

Doctor's answer:

Hello. Deficiency of trace elements can lead to decreased blood calcium, which increases the excitability of the brain and vegetative nervous system, causing the baby to sleep poorly at night. Calcium and vitamin D supplementation is needed. If calcium is deficient, the baby's fontanelles may not close properly; if zinc is deficient, the corners of the mouth are often prone to ulcers.
Suggestions: If you want detailed information, please have a thorough check-up at the hospital. Pay attention to your diet.!!!! Thank you...
