Worst IBS Trigger Foods: What to Eat Instead

6. Caffeinated drinks

Caffeine is a well-known gastrointestinal stimulant that speeds up peristalsis, the muscular contraction and relaxation of the GI tract that pushes food through the body. Some studies suggest women are more prone to IBS as a result of caffeine consumption. Beverages such as coffee, energy drinks, soft drinks, and black or green tea have enough caffeine to irritate the digestive system quickly, as do some over-the-counter analgesics. Though caffeine has numerous health benefits, as well, people with IBS should seek alternatives such as herbal teas. Even decaf coffee can pose an issue because it leads to the production of gastrin, which stimulates bowel movements.
