Allergic diseases, primarily respiratory, cutaneous, and various food-related allergies, are on the rise. Recently gut, skin, and lung microbiota have been shown to have a potential role in allergic reactions primarily because of their impact on the immune system. At the same time, various factors, including age, food, drugs, and lifestyle, may modulate the microbiota, thus influencing allergy. In this chapter, we discuss the role of the microbiota in the immune system and its subsequent effects on allergic reactions. We also discuss the various possible interventions, including the use of probiotics, prebiotics, and synbiotics as potential anti-allergic agents.
