Does drinking coffee on an empty stomach hurt your stomach?

Coffee has replaced tea as the most popular refreshing drink for modern people.

Many of us have made a habit of waking up with a cup of coffee to wake us up and have a cup of coffee before work to boost our productivity. What’s more, we may drink a large amount of coffee in a short time to cram for a certain exam or project.

At this time some people began to worry, long-term drinking coffee will not be harmful to the body ah?

Some Internet articles say that drinking coffee on an empty stomach can cause stomach ulcers or duodenal ulcers… Well, let’s analyze the evidence.

Coffee does have some effects on the gastrointestinal tract

Caffeine is the main ingredient in coffee that wakes you up and is also the main ingredient in tea. But it’s not just caffeine that can cause gastrointestinal problems. Decaffeinated coffee can also cause digestive symptoms.

Current studies suggest that coffee’s effects on the gastrointestinal tract mainly include:

  • Increase the secretion of gastric acid;
  • Loose esophageal sphincter aggravates acid reflux.
  • Promote peristalsis of the small intestine.

That stomach acid is much, can you get gastric ulcer? Esophagus sphincter muscle was loosened, can you aggravate acid, the symptom of heartburn?

But coffee does not cause ulcers

In 2013, a study of 8, 013 healthy people found that coffee consumption was associated with peptic ulcer. The final result was that the occurrence of gastric ulcer or duodenal ulcer was not related to coffee consumption, but mainly related to the presence of helicobacter pylori infection and smoking.

In other words, to prevent ulcers, bactericidal (helicobacter pylori), smoking cessation is useful, not coffee!

Similarly, after studying the relationship between coffee and gastroesophageal reflux disease, which is mainly manifested as reflux heartburn, it is also believed that coffee does not cause gastroesophageal reflux disease.

In this study, the author also integrated many previous studies on the relationship between coffee and ulcer, and found no association between coffee and the occurrence of peptic ulcer.

So how exactly do you drink coffee?

Coffee really is a kind of excitant food, because be a kind of excitant substance really theoretically, can stimulate gastric acid to secrete, won’t cause ulcer directly, but may increase the happening risk of ulcer.

Therefore, our attitude towards coffee is summarized as “appropriate for people, enough is enough”.

These people can keep drinking

If you’ve made a habit of drinking a cup of coffee every morning on an empty stomach and you don’t have stomach pains, heartburn ulcers, or gastroesophageal reflux, just keep up the habit.

These people had better not drink it

If you feel uncomfortable after drinking coffee, such as acid reflux heartburn, or already have gastric ulcer, duodenal ulcer, inflammatory bowel disease, irritable bowel syndrome, gastrointestinal surgery recovery period and other gastrointestinal diseases, it is best to gradually give up the habit of drinking coffee.

Although there is little evidence that coffee causes peptic ulcers, there is evidence that it may aggravate or delay the healing of ulcers.

Should you drink coffee or not?

In fact, not only in the aspect of digestion, long-term drinking coffee, for the most concerned about several health indicators, including blood pressure, heart rate, blood fat, blood sugar, etc.

Most, if not all, of these effects are beneficial, and for most people the benefits of moderate coffee consumption outweigh the risks (if any).

So as for whether to drink coffee or not, as long as you are happy.
