This webinar explores the critical role of gut microbiota in shaping early life immunity and the development of allergic diseases. The gut microbiome, consisting of a vast array of microorganisms, influences immune system development from infancy. Disruptions in this microbial balance can lead to increased susceptibility to allergic conditions, including asthma, eczema, and food allergies. Key factors such as genetics, mode of birth, breastfeeding, and antibiotic use play a significant role in determining gut microbiota composition. Understanding these influences can inform strategies to promote a healthy gut microbiome, potentially reducing the risk of allergic disease. The latest research findings on this topic will be discussed, offering valuable insights for healthcare professionals and researchers. Promoting early life interventions that support a balanced gut microbiota may contribute to better long-term health outcomes. This webinar provides a comprehensive overview of the intersection between gut health and immune system development in early life.
