Can cappuccino cause diarrhea

Caffeine, a primary component in cappuccinos and other coffee beverages, can have a laxative effect on some people. Therefore, for some individuals, consuming a cappuccino or other caffeine-rich drinks might lead to digestive discomfort, including diarrhea. Here’s a closer examination of the relationship:

Caffeine’s Role

Caffeine can stimulate the colon and induce bowel movements. This stimulation might be stronger in some individuals, especially those who aren’t regular caffeine consumers or who are particularly sensitive to caffeine.


Reasons for Caffeine Sensitivity

  • Genetics: Some people metabolise caffeine more slowly than others due to genetic factors, making them more susceptible to its effects.
  • Irregular Consumption: Those who don’t regularly consume caffeine might experience more pronounced effects when they do.
  • Other Health Conditions: People with certain health conditions, like Irritable Bowel Syndrome (IBS), might be more sensitive to the effects of caffeine.

Other Components in Cappuccino

It’s not just the caffeine in cappuccino that might upset someone’s stomach:


Lactose, a sugar found in milk, can cause digestive distress in individuals who are lactose intolerant. Symptoms can include bloating, gas, and diarrhea. Since cappuccinos contain steamed milk and foam, they can be problematic for those with this intolerance.


Coffee is naturally acidic, and for some, this can irritate the digestive system, leading to stomachaches and diarrhea.

Other Considerations

Quantity: Consuming large amounts of coffee or several cappuccinos in quick succession can increase the risk of digestive discomfort.
Empty Stomach: Drinking coffee on an empty stomach can amplify its effects, potentially leading to digestive issues or discomfort.
Additives: Some people might react to additives like sugar substitutes or certain flavourings that can be found in some coffee drinks.


While cappuccinos and other coffee beverages are enjoyed by many around the world without issue, they can cause diarrhea or other digestive discomfort in some individuals. Factors such as caffeine sensitivity, lactose intolerance, or the drink’s acidity can contribute to this. If someone suspects that cappuccinos or coffee are causing digestive problems, it might be helpful to reduce intake, try alternative milk options, or consult with a healthcare professional.
