Caffeine does not cause the SII, but it can worsen its symptoms, which makes conscious consumption crucial for those affected.
While caffeine increases energy and alert state, it can also trigger or worsen the symptoms of the SII, especially in sensitive individuals.
SII is a prevalent gastrointestinal condition characterized by symptoms such as abdominal pain, swelling, gas and altered intestinal habits such as constipation or diarrhea. Lifestyle, stress and diet also contribute to the development and exacerbation of such conditions. It is believed that caffeine affects the SII, particularly when consumed through tea or coffee. Dr. Bhavesh Patel, gastroenterologist consultant of the General Hospital of Bhailal Amin, Vadodara, Gujarat, shares everything he needs to know:
Caffeine is a natural stimulant found in tea and coffee, recognized for its action in the nervous system. It improves the state of alert and energy levels, which makes it a common part of the daily routines. Caffeine also stimulates the gastrointestinal tract, promoting an increase in intestinal motility and resulting in faster intestinal movements. For people suffering from SII, particularly the predominant IBS of diarrhea, this can be problematic.
Clinical observations and some studies indicate that excessive caffeine consumption is associated with an increase in SII symptoms. Coffee, in particular, is known as gastrointestinal irritating. It can stimulate the secretion of gastric acid and act as an intestinal stimulant, which can cause dumps, urgency and additional bathroom visits.
Tea tends to be a bit softer in the stomach because it is less irritating, but it is not completely without worries. Black and green teas contain caffeine, although in lower quantities compared to coffee. The HERBALS often do not have caffeine, but they can still contain compounds that influence digestion. For example, mint tea can relax intestinal muscles and help relieve symptoms, while other herbal teas can reduce inflammation.
Sensitivity to caffeine among people with SII varies greatly. Some people can tolerate one or even two cups of coffee or tea without problems, while others may experience symptoms even with small quantities. Reactions can also be influenced by stress and other dietary factors. It is also worth noting that tea and coffee are often consumed with milk and sugar, which can be triggered from the SII.
Caffeine is not a cause of the SII, but it can exacerbate symptoms in those already diagnosed with the condition. Reducing intake, changing to decaffeinated options or monitoring symptoms after caffeine consumption can offer useful clues to control the problem.
