Weakness of the spleen and stomach in children is caused by the following conditions: First, due to the congenital genetic factors of children, some children are born prematurely or their parents are physically weak, so children will have congenital weakness of the spleen and stomach. Secondly, improper diet can lead to damage to the spleen and stomach if the child is a partial eater, a picky eater, and likes to eat a lot of cold, greasy, fatty, sweet and thick foods. Then, if the child is often sick, the damage of the disease will also affect the child’s spleen and stomach, which will lead to the weakness of the spleen and stomach. Finally, if children often apply drugs that clear heat and detoxify toxins, such as children often apply drugs containing Scutellaria baicalensis and Gardenia jasminoides, this can also cause spleen deficiency in children.
