Does Coffee Really Cause Stomach Problems? Here's What the Science Says

Worried that your daily coffee habit might be messing with your digestive health? A recent study offers some comforting news: you can enjoy your coffee without fearing damage to your gut.

If you’ve ever had a cup of coffee, you know it can certainly get things moving. But just because it speeds up natural processes doesn’t mean it’s harmful to your stomach. Researchers analyzed data from over 8,000 people and found no evidence that coffee negatively impacts stomach health—no harm to the intestines, no increased risk of ulcers. This lack of association was consistent regardless of how much coffee people drank, meaning even frequent coffee drinkers weren’t at a higher risk for these digestive issues.

But what about heartburn or indigestion? Since coffee is acidic, many wonder if it could cause reflux. A review of 15 studies found no direct link between coffee consumption and heartburn symptoms. While it's conceivable that coffee might contribute to reflux, this generally only becomes a concern when you’re on your fourth cup or more.

Of course, everyone’s body is different. If you have specific digestive symptoms or conditions, it’s always best to consult a healthcare professional for personalized advice. But if you’re generally healthy, enjoy coffee, and are worried about its impact on your digestion, this research suggests you can sip your coffee without concern.

In short, for most people, coffee is not the digestive enemy it’s often made out to be. So go ahead—pour yourself another cup and enjoy it guilt-free!
