Mothers of babies with food (feeding) allergies are often overly anxious and torn, and in this regard I need to emphasize the following points: First, infants and young children are vulnerable to food allergies. According to the data, half of the allergic children who visit the clinic do not have a family history. So to some extent, a large proportion of these visits are growth process problems. Of course, one also needs to be alert to the presence of certain infections, allergic diseases or a combination of autoimmune diseases, metabolic genetic or congenital anatomical abnormalities. The causes of pediatric food allergy/intolerance are often multifactorial, i.e., environmental (e.g., seasonal factors), body immune status (e.g., vaccination, other internal factors such as normal intestinal flora), allergen exposure (feeding), and genetic factors (allergic and other disease gene polymorphisms). However, each child seen has different major factors and major conflicting aspects. Do not consider the type of formula fed as the only factor and do not consider the rash (eczema, acute/chronic urticaria) or the appearance of the stool (sticky stool, bloody stool, constipation) or the results of routine stool tests (white blood cells, red blood cells or occult blood) as the main basis for the choice of feeding method and formula, or even normal stool as the goal, while ignoring the advantages of breast milk and the mother’s goal of raising her baby “successfully”. The goal of “successful birth education” (healthy development of mind and body: physical growth, psychological, intellectual and behavioral development). Types of pediatric food allergy and intolerance 1, rapid-onset: <1h, IgE-mediated; small measurement is triggered, allergic reactions are heavy, skin symptoms, bloodshot stools are common. 2.Late onset: >24h – several days, T-cell mediated (IgG) able to tolerate normal doses, skin, gastrointestinal or respiratory symptoms are common. 3. Mixed or alternating type: mechanism, typical symptoms can appear after 6-8 hours, gastrointestinal symptoms are common. 4, food allergy/intolerance manifestations 1, diarrhea/bloody stool or rectal bleeding/vomiting/refusal to eat: growth retardation/constipation/abdominal pain; oral allergy syndrome such as pharyngeal/lip/tongue edema; wheezing/asthma/cough/rhinitis; eczema/itching/rash/edema/dryness; acute allergy syndrome including shock state. 2. Symptoms triggered by local mechanisms: e.g. gastroesophageal reflux, reflux esophagitis, proctocolitis perianal inflammation or anal fissure (causality is debated). (16%-42% of children with a history of gastroesophageal reflux have symptoms of milk protein allergy). Symptoms include: dysphagia choking, vomiting blood, black stools, hiccups, nausea/belching, bradycardia, aspiration, laryngitis/asthmus, hoarseness, etc. 3. Mixed or secondary mechanisms inducing symptoms: e.g. chronic allergic states, long-term medication (antibiotics probiotics PCP over application, vaccine related diarrhea), long-term single amino acid formula feeding, etc. Resulting in endogenous or auto-infection, auto-inflammation and auto-allergy; phyla disorders Insufficient activity of relative enzymes (e.g. lactase), intestinal motility disorders, developmental delays. Symptoms include: irritability, abdominal pain, sleep disturbance, food refusal, growth disorders, iron deficiency anemia, wheezing, apnea/sudden infant death syndrome (reported abroad). Parents and physicians are unclear about the overall, dynamic status of the child being seen. It is not clear whether the child is healthy, subhealthy (or has problems during growth and development) or sick. Rushing to conclusions, resulting in excessive consultation, over-diagnosis and over-treatment. 2. Lack of integrated medicine and systemic medicine view of disease. The rush to seek medical advice, the pursuit of authoritative diagnosis, excessive attention to laboratory tests (repeated stool routine culture, the pursuit of colonoscopy, allergens, molecular biological indicators of Western medicine disease diagnosis), only focus on drug treatment, milk powder products selection, mother how to avoid food. Sixth, reflections and suggestions 1, promote the modern medical view of disease (not a single Western or Chinese medical view of disease). 2. Update parents’ concepts: establish a record of the overall performance of food allergies and dynamic laboratory observations, (as mothers in developed countries do, carefully write baby growth logs and recipes; organize records of dynamic experiments and test results; carefully choose to deal with breastfeeding and formula feeding, vaccinations and various antibiotics, probiotics and other choices. It is important to know: how to feed in a specific way, how to transform the feeding method, these details are very individual, mothers can communicate with each other, but ultimately need to “grow with the baby at the same time”, “listen to yourself! . 3, professional and general practitioners need to follow the principles of disease standardization and individualized diagnosis and treatment of diseases (both to follow the current “guidelines” and to make specific analysis of the specific children seen) from the “era” perspective, at present, both Western medicine The basic concepts of disease, infection, allergy, immunity, etc. are being revised and updated. In addition, in the face of China’s long-standing Chinese culture and large population, the integration of Chinese and Western medicine is the only way to solve the problems of difficult and expensive medical treatment, and the increasing complexity of disease diagnosis and treatment.
