If a child has pinworm disease, it is recommended to register with the Department of Pediatric Gastroenterology or General Pediatrics. Pinworms are mainly parasitic in the intestine and can cause damage to the intestinal mucosa, with no obvious symptoms in mild infections and malnutrition and metabolic disorders in severe infections. The symptoms can be mainly perianal itching, caused by the toxic substances produced by pinworms and mechanical stimulation, especially at night, which affects sleep. Children cry and fuss, and scratching causes perianal skin peeling, congestion, rashes, eczema, and even purulent infections. Pinworms burrowing into the intestinal mucosa and mechanical or chemical stimulation in the gastrointestinal tract can cause loss of appetite, nausea, vomiting, abdominal pain, diarrhea and other symptoms. As the parasite excretes metabolites in the body, it causes symptoms such as mental excitement, insomnia, and night terrors in children.
