Why is my poop always watery after drinking coffee?

Coffee is an indispensable drink for many people in the morning. It can refresh the mind and increase concentration. However, some people find that their stool becomes loose after drinking coffee. So why is the stool always loose after drinking coffee? This article will explore this issue.

1. Coffee contains caffeine

First of all, we need to understand that coffee contains a substance called caffeine. This substance has a stimulating effect and can promote intestinal peristalsis. When we drink a cup of steaming and fragrant coffee, the large amount of caffeine contained in it will be quickly absorbed into the blood.

2. Research results from Harbin Medical University

According to a study conducted by Harbin Medical University, after taking a higher dose of caffeine (more than 400 mg per day), most people will experience faster intestinal peristalsis and more frequent bowel movements. This is one possible reason why the stool is always watery after drinking coffee.

3. Coffee stimulates gastric acid secretion

In addition to promoting intestinal peristalsis, coffee can also stimulate gastric acid secretion. When we drink a cup of strong coffee, the substances contained in it stimulate the gastric mucosal cells to release more hydrochloric acid. In this way, the excessive hydrochloric acid produced in our body will cause other parts of the digestive system to be affected.

4. Coffee affects intestinal water absorption

In addition, the study also found that after consuming higher doses of caffeine (more than 400 mg per day), the body's ability to absorb water decreased. This means that after drinking coffee, the water that should have been absorbed and utilized by our body may have been excreted.

5. Individual differences and habitual intake

However, it should be noted that not everyone will have diarrhea after drinking coffee. This is because of individual differences. Some people may not be sensitive to the stimulating effects of caffeine, or they may have become accustomed to consuming large amounts of caffeine.

6. Other possible reasons

In addition, there are other possible reasons for diarrhea after drinking coffee. For example, some people may be allergic to the acid contained in coffee; or they may have intestinal problems, such as gastroenteritis, ulcers, etc.

in conclusion

In summary, diarrhea after drinking coffee is a common phenomenon. This is mainly attributed to the stimulant contained in it, caffeine, which affects intestinal motility and gastric acid secretion, and reduces the ability to absorb water. However, not everyone will experience this situation, and individual differences and habitual intake will also affect the results.
