Question
An 8-year-old boy experienced upper limb convulsions during his nighttime sleep, with his fingers straightening and his thumb pointing towards the palm of his hand, accompanied by vomiting white foam. Similar symptoms have occurred three times. Is this phenomenon caused by calcium deficiency?
Answer
Calcium deficiency in children may be associated with nocturnal convulsions and vomiting white foam. Typically, severe calcium deficiency or similar symptoms may require special attention. It is recommended to increase the intake of calcium-rich foods such as hot milk, green peppers with pork liver, fish meat, and mushrooms. Additionally, consider traditional Chinese medicine treatment, engage in more physical activity, and expose yourself to sunlight appropriately, as these methods can help improve the symptoms.
