Pediatric ascariasis usually has no obvious facial features or characteristics, and may appear yellowish and thin due to anemia. In pediatric ascariasis, roundworms compete for nutrients in the intestines, and the irritation of the intestinal mucosa by roundworms can cause gastrointestinal reactions in children, leading to anorexia, which affects the intake of nutrients in children. Ascaris lumbricoides also causes a decrease in the function of the gastrointestinal tract, resulting in impaired absorption of nutrients. Over time, the child will suffer from wasting, anemia and other symptoms, resulting in a decrease in facial fat and a yellowish color (yellow and lusterless). There are also children who do not have obvious facial features, but may be accompanied by symptoms such as teeth grinding in sleep and abdominal pain. When children are found to be suffering from intestinal roundworm disease, it is important to consult a doctor in time to take targeted treatment measures, so as not to delay the condition and affect the health of the child.
