The gastrointestinal tract plays a central role in many chronic and systemic diseases and many clients present with IBS type symptoms. Addressing gut health is critical from a Functional Medicine perspective yet keeping abreast of the latest research and trends and applying these to particular cases alongside interpreting laboratory data be challenging and confusing and the best course of action is not always clear.     

This on-demand course  synthesises and reviews the latest research and trends and give practitioners  confidence in applying these to cases and interpreting laboratory data. It looks at the most recent research on the interplay between gut barrier, microflora and immune function and what can go wrong with digestion and absorption processes and why. It presents laboratory assessment options around malabsorption and digestion, dysbiosis and IBS. Finally it provides diet and lifestyle management suggestions based on specific IBS symptoms and patterns.

This course has been structured and designed based on best practice in delivering an effective and interactive online learning experience. Anonymised case study data is used.

By the end of the recording you will be able to:

  • Critically review the main influences on digestion and absorption; gut barrier and immune functions and gut microbiome integrity
