What causes a child to cry and have an uncomfortable stomach?

Patient's question:

The child always cries and fusses at night when sleeping

Doctor's answer:

Lack of trace elements, reduced blood calcium levels can increase the excitability of the brain and vegetative nervous system, leading to restless sleep in babies at night. Calcium and vitamin D supplementation are needed. If calcium deficiency occurs, the fontanelles of the baby may close improperly; if zinc deficiency is present, mouth ulcers are often observed around the corners of the mouth. It is recommended to take the baby to the hospital for a trace element check and supplement accordingly based on the situation.
Children's bodies have weaker immunity, making them more prone to pediatric general surgery issues. For parents, it is important not to panic and should promptly take their children to a professional hospital for examination and treatment. Regular check-ups should be conducted for the child, and medications should be used under the guidance of a doctor.
