Chamomile and fennel teas, often perceived as healthy morning drinks, can cause extreme bloating and digestive discomfort in people with Irritable Bowel Syndrome (IBS), according to experts from Monash University. These herbal teas contain fructans, a type of carbohydrate that is difficult for some individuals to digest.
Fructans in Herbal Teas Trigger Gas and Bloating
Monash University, which developed the internationally recognised low-FODMAP diet, states that chamomile and fennel are rich in fructans, a category of fermentable carbohydrates known as FODMAPs. When these carbohydrates are not fully absorbed in the small intestine, they travel to the large bowel, where gut bacteria ferment them, producing gas that leads to bloating, abdominal discomfort, and pain.
Research referenced by the university indicates that some IBS sufferers may experience "extreme bloating" after consuming high-FODMAP foods and beverages. The low-FODMAP diet is commonly used by healthcare professionals to help manage IBS symptoms.
NHS on IBS Symptoms
The NHS describes IBS as a widespread condition affecting the digestive system, with symptoms including bloating, stomach cramps, diarrhoea, and constipation. While no single food affects everyone, maintaining a comprehensive food diary and identifying personal triggers can help minimise flare-ups.
Monash University advises that peppermint tea is considered a low-FODMAP option and is generally better tolerated by those following the diet. Ginger tea may also be suitable for many people, though individual tolerance levels can vary.
Professional Guidance Recommended
The British Dietetic Association recommends that anyone suffering from persistent bloating or digestive issues should consult a medical professional rather than unnecessarily eliminating large food groups from their diet. Dietary adjustments for IBS are most successful when undertaken with guidance from a registered healthcare professional or dietitian.
While herbal teas are widely consumed in the UK and globally, experts emphasise that what benefits one person's digestive system may not suit another. Identifying personal triggers is crucial to preventing unwanted discomfort.
