Noma is a general term for noma and stagnation, and is a common symptom in pediatrics in TCM clinics. The cause is complex, mainly due to improper feeding, partial feeding, and wasting diseases, resulting in damage to the spleen and stomach, leading to a decrease in digestion and absorption, which in turn causes the following series of symptoms: 1. The patient’s body weight is usually below 60% of the normal weight standard. The most important thing is that the child’s hair is dry, thin, lusterless and easily broken, and the hair has a scorched appearance. The main feature is edema, and in severe cases, sunken edema may appear in the lower limbs and the whole body. In addition, children with chancre can also develop nutritional anemia, of which nutritional iron deficiency anemia is the most common. In addition, vitamin and trace element deficiencies, spontaneous hypoglycemia, and infections may also occur. In the early stage of the disease, there are no specific and sensitive diagnostic indicators, so the decrease in plasma albumin concentration is generally considered as the characteristic change of the child.
