While the idea that our gut can influence our brain is not new, this is a rapidly growing area of research. Find out more on how gut microbes influence anxiety and stress and why tackling these psychological traits matters for irritable bowel syndrome.

Diets for irritable bowel syndrome: what you need to know

Food is considered the main trigger of digestive symptoms in the vast majority of patients living with IBS. While finding foods that do not prompt gastrointestinal (GI) symptoms has been a challenge for many people with IBS, restrictive diets can come with potential risks. Learn more about diets with evidence in IBS.

Chronic abdominal pain, diarrhea, constipation, and bloating are common gastrointestinal symptoms. While a structural or an organic disease can be suspected because of the symptoms and is often easy to be diagnosed by endoscopy or imaging methods, sometimes gastrointestinal symptoms are not related to any alteration that may be seen through diagnostic techniques, and consequently have been classified under the umbrella of “disorders of gut-brain interaction”.

Bacteria and fungi in the human gut microbiota may contribute to the underlying mechanisms of IBS, which means the latter can be explored as a potential target for IBS. This article explores what is known about the role of the gut microbiome and yeast probiotics in irritable bowel syndrome.

Little is known about the relationship between diet, the composition and function of the gut microbiota and clinical symptoms of IBS. New findings identify how IBS symptom severity is related to a higher intake of foods with poor nutritional quality and gut microbiome features at both subspecies level and metabolic pathways involved in carbohydrate metabolism.
