When a child at home does not like to eat, grows thin, or has temper tantrums, or has thinning hair that grows vertically, some elderly people in the family will say: this child has “chancre”. When we go to the hospital, we also hear that doctors make this diagnosis for their patients. The most important thing is that the patient will be able to see the symptoms. What is this disease? The following is a brief discussion of this disease. The first thing is that noma is a Chinese medical term that is probably equivalent to malnutrition in Western medicine. In the ancient times, “cholera, pox, fright and cholera” were listed as one of the four major signs of pediatrics, which shows how common it is. In modern times, this disease is also not uncommon, but the cause has changed. In ancient times, children were not able to eat nutritious food, which is caused by absolute lack of food. What are the manifestations of chancre in children? The incidence of this disease does not differ significantly between men and women, but is slightly more common in boys; it occurs from 6 months to 16 years of age. The longer the onset of the disease, the more severe it is. Clinical manifestations include: anorexia; feeding difficulties (partial and picky eating, slow eating, containing food, playing while eating or watching TV while eating, etc.); dry vomiting; abdominal pain when eating; dry or loose stools; abdominal distention; weight loss, no weight gain or loss, large belly; yellow and forked hair, locks, vertical growth; yellowish white face, spots on face, white spots on nails; grinding teeth, biting fingers, biting corners of clothes, etc.; sleep disorders, crying at night, night sweats, sleeping on one’s back, turning over a lot; sleeping on one’s back, sleeping on one’s stomach, etc. The child’s sleep disorders include crying at night, night sweats, sleeping on the stomach, turning over a lot, high temper, irritability, and moving around. When children have chancre, their nutritional status becomes worse, and after months of accumulation, for young children, it is easy to cause weakness, malnutrition, and increase the chance of infections such as colds and coughs. The most important thing is that you can be sure that you will be able to get the most out of your life. This is the key period to determine the final height of the child, and if you miss it, you will not have it again. In addition to the nutritional effects of noma in school-age children, the impact of the disease on the final height is also important because of the long-term slow growth of height and even the delayed and accelerated growth of puberty. In terms of treatment, Chinese herbal medicine can be used to regulate, appropriately supplement the nutrients required for growth, and external treatment of Chinese medicine. Oral herbal medicine for spleen and stomach is not much elaborated, parents are more clear. The external treatment method needs to be explained, Chinese medicine external treatment is a useful supplement to oral medication, because this disease is a chronic disease, oral medication for too long, children’s compliance is poor, more can not be too long to adhere to, then with external treatment, there is an early effect of time, shorten the course of action. External treatment includes: abdominal physiotherapy (low-frequency pulse point treatment), picking (picking noma, picking the “four suture points”), massage/chiropractic. The duration of treatment is 1 to 3 months. The above external treatment methods are used according to the child’s physical condition and specific analysis.
