Question
What diseases can pediatric surgery treat? Which symptoms belong to pediatric internal medicine? What causes rickets in children?
Answer
Rickets is caused by a deficiency of an active form of vitamin D, which leads to the body’s inability to absorb calcium properly, resulting in early calcium deficiency. Symptoms include nervous system hyperactivity, such as difficulty falling asleep deeply, excessive sweating after naps, frequent night terrors, and hair loss on the pillow. If vitamin D is not supplemented in time, bone abnormalities may occur as the child grows older.
