Children’s respiratory and digestive systems are not fully developed, so coughing and vomiting symptoms are common from time to time. Cough is a common symptom of the respiratory tract, and the common causes may first be related to the inhalation of specific or non-specific objects, such as specific mites, dust, and non-specific formaldehyde. It may also be related to recurrent infections of the respiratory tract, such as some viral and bacterial infections, and in early childhood, parasites may also be present. Some children have poor autoimmunity, so they are allergic to many foods, so they are also prone to coughing. In addition, of course, the presence of uncontrollable environmental factors, such as a child who has adapted to the current environment and is suddenly transferred to an unfamiliar environment, can also cause coughing. Vomiting is a common symptom of the digestive tract. It is mainly due to the malfunction of the spleen and stomach in transporting and transforming, resulting in the upward rebellion of stomach gas, which makes the putrefied matter in the stomach come out of the mouth. For children, most of the vomiting is caused by improper diet, eating too much, especially too much cold food, like to eat all kinds of greasy food to stimulate the spleen and stomach, will lead to poor digestion of the spleen and stomach, qi does not descend, but upward rebellion, and finally vomiting. So the child’s development is not yet complete, in daily life, must be carefully cared for, reasonable diet.
