What Is IBS?
Irritable Bowel Syndrome (IBS) is a common, lifelong functional gastrointestinal condition. People with IBS often experience stomach cramps, bloating, constipation, or diarrhoea. Symptoms can come and go, lasting from a few days to several weeks or longer. While the exact cause is unknown, contributing factors may include disruptions in the gut–brain axis, stress, diet, and changes in the gut microbiome.
Understanding the Impact
IBS affects up to 20% of the population in Western countries, including the UK. Chronic symptoms can interfere with daily life, affecting mental health, sleep, and overall wellbeing. Stress, anxiety, and dietary triggers often worsen symptoms.
How Sourdough Can Help
Research suggests that sourdough fermentation can lower levels of FODMAPs, specific carbohydrates that commonly trigger IBS symptoms. Slow fermentation also partially breaks down gluten and other compounds, making bread easier to digest. At The Sourdough School, we use long fermentation techniques and botanical blend flours that may support a more comfortable digestion for some people with IBS.
Additionally mindful baking and eating, core aspects of the BALM protocol can also help regulate digestion and reduce stress-related flare-ups.
Lifestyle, Diet, and Medical Support
Many people with IBS benefit from a varied diet, stress management, and tailored sourdough choices. Techniques like low-FODMAP baking, gradual fibre introduction, and careful recipe adjustments are key. Health professionals use tools like the Bristol Stool Scale for monitoring symptoms. Dr Vanessa Kimbell has written an overview of sourdough bread and IBS if you’d like to read more about bread and digestion.
