1. stool: normal stool should be yellow, regular in shape, dry and not thin, and have good defecation habits. If the color, shape or frequency of a child's stool changes, it may be a signal of disease. For example, black stool may indicate gastrointestinal bleeding; White stool may indicate hepatobiliary system diseases; Red stool may indicate anal or rectal bleeding; Dilute water samples may indicate digestive system infection or food poisoning; Constipation or diarrhea may indicate intestinal dysfunction.
2. complexion: Chinese medicine believes that complexion is the external manifestation of the functional state of the five internal organs. A healthy complexion should be ruddy, indicating sufficient blood. If the child's face is yellow, it may be that the spleen and stomach function is insufficient, resulting in poor digestion and absorption of food; Pale complexion may be caused by deficiency of both lung and spleen and deficiency of qi and blood; The face is red, which may be getting angry; The blue complexion may be caused by the invasion of cold evil and the poor operation of qi and blood; The dark complexion may be due to insufficient renal function and poor metabolism of water and liquid.
The above are just some basic judgment methods, and the specific symptoms need to be comprehensively judged in combination with the child's other symptoms and physique. If the child has abnormal stool or complexion, it is recommended to take the child to the hospital in time for accurate diagnosis and treatment.
