In cases of food poisoning that require medical attention, yes, a pediatrician can help treat kids for food poisoning. The pediatrician will get a detailed history of the illness, most likely from the parent depending on the age of the child, that will include how long they’ve been sick, what the symptoms have been and what foods were eaten prior to getting sick. The doctor will most likely also want to perform a physical exam to check for signs of dehydration. The pediatrician may want to perform additional diagnostic tests such as a blood test, stool culture or examination for parasites, depending on the symptoms and health history to confirm the diagnosis and help identify the cause. In the case of an organism being found in the stool sample, the local health department may be informed to try to find the source of the parasite and determine if it is linked to an existing outbreak.
