When children have worms in their stomachs, they will show symptoms such as abdominal pain, anorexia, dyspareunia and xenophagia. 1. Abdominal pain: If the child has parasitic infection, it will affect the normal function of the intestinal tract, making the intestinal tract spasm and causing abdominal pain. 2. Anorexia: the presence of parasites in a child’s intestines will affect the digestive function, affecting the child’s appetite and causing anorexia and partiality. 3. Poor development: If there are parasites in the child’s stomach for a long time, it will have a more obvious effect on the physical development, and the child’s figure will be smaller than his or her peers, and his or her body will be thin and weak. 4. Ectophagy: Some parasites located in the body will cause the child to like to eat chalk, pencils, etc., known as ectophagy. If you suspect the existence of parasites in the child’s body, you need to consult a doctor in time, conduct routine stool examination to determine the presence of eggs, and under the guidance of the doctor to carry out standardized treatment, to promote the alleviation of uncomfortable symptoms as soon as possible.
