The term “diarrhea” originates from the Greek diarr, which means through, and rhein, which denotes flow. Although this descriptive term is appropriate for the symptoms, the word diarrhea may not have the same meaning for all patients and physicians.


Specialty care for asthma can be confusing because each type of provider may have a different focus. Pediatric allergists specialize in the reactions of the immune system to common environmental allergens, such as pollens, dust mites, or pet dander, that can play a key role in asthma. Allergists use skin tests to detect allergies and may, in some cases, treat allergies by giving repeated small doses of the allergen.
