21 Mar 2026 BANT Member Anna Mapson Publishes Book on IBS
BANT is proud to support BANT Member Anna Mapson and the release of her new book Inside knowledge form people with IBS and SIBO.
UK nutritional therapist and IBS specialist Anna Mapson released a new book, ‘Inside Knowledge for people with IBS and SIBO’ on 8 January, aimed at people living with ongoing digestive symptoms who feel overwhelmed by conflicting diet advice and online ‘gut hacks’.
Drawing on 10 years of clinical experience, the book explains the underlying causes of IBS symptoms such as bloating, constipation, diarrhoea, gas, and abdominal pain, before guiding readers through practical, sustainable ways to manage them.
The book is structured in three parts. It first explains digestive conditions including IBS and SIBO (small intestinal bacterial overgrowth), alongside causes of constipation or diarrhoea. It then introduces Anna’s Gut Reset Cogs model, showing how diet, lifestyle, and the gut–brain connection work together. The final section focuses on symptom management, supplements, hormones, flare-ups, and long-term life with IBS.
Unlike many gut health books, it avoids extreme diets which can cause fear around food. The book focuses instead on better understanding digestion, expanding your diet, and practical changes that can fit in everyday life.
Each chapter starts and finishes with a client story, giving people with IBS real life examples of how digestion can improve.
The book is for people who don’t know what to eat without bloating, and feel confused by contradictory gut health advice.
