Doctor's answer:

The possibility of calcium deficiency is the most likely cause for a child's condition. It generally leads to symptoms such as irritability, excessive sweating, and poor appetite with weight loss. In this case, active calcium supplementation is necessary. It is recommended to first focus on rest, and maintain a light, warm, and easily digestible diet. Eating more eggs and liver is advisable. It is recommended that your child actively take zinc gluconate calcium oral liquid for treatment. Exposing the child to sunlight is also beneficial.
