Abstract: The function of the spleen in children is often insufficient, and improper feeding, or disease damage may cause the fact that food can't be digested, which is food accumulation。Although it is a disease of the spleen, Professor Sun Liping believes that long time of food accumulation can form internal heat syndrome, thereby inducing a variety of pediatric diseases. Attention should be paid to the physical changes caused by congenital abnormality and acquired dystrophy. Based on the physiological and pathological characteristics of children, Yin and Yang theory, five-element theory and constitution theory, and through combination with more than 30 years of clinical experience of Professor Sun Liping, this paper explores the etiology and pathogenesis of children's diseases caused by "food", the disease outcome transformed by "heat", the diagnosis experience from "observation", and the treatment method by "elimination". A new line of thinking of "same treatment for different diseases" is provided for the diagnosis and treatment of abdominal pain, cough, asthma and tic disorders caused by food accumulation.

Key words: Same treatment for different diseases, Abdominal pain, Cough, Asthma, Tic disorders, Child
