Why do I get diarrhea when I drink beer?
Recently, many netizens have reported on social media that they experience diarrhea after drinking beer. This phenomenon has triggered widespread discussion, especially during the peak beer consumption period in summer, when similar problems appear more frequently. So, why do I get diarrhea when I drink beer? It may be related to the following reasons.
1. The ingredients in beer irritate the gastrointestinal tract

Beer contains alcohol, carbon dioxide, yeast and other ingredients, which may irritate the gastrointestinal tract. Alcohol, in particular, will speed up gastrointestinal motility and cause diarrhea. In addition, the carbon dioxide in beer may also cause bloating or gastrointestinal discomfort.
| Ingredients that may cause diarrhea | Mechanism of action |
|---|---|
| alcohol | Accelerate gastrointestinal motility and stimulate the intestines |
| carbon dioxide | Causes bloating and increases gastrointestinal pressure |
| Yeast | May cause allergies or indigestion |
2. The beer refrigeration temperature is too low
Many people like to drink cold beer, but too low a temperature may irritate the gastrointestinal mucosa, causing gastrointestinal cramps or diarrhea. This is especially true for people with sensitive stomachs.
| Beer temperature | Effects on gastrointestinal |
|---|---|
| 0-4°C (chilled) | May cause gastrointestinal cramps |
| 4-8°C (refrigerated) | Less irritating to the gastrointestinal tract |
| 8-12°C (normal temperature) | Better gastrointestinal adaptability |
3. Beer does not pair well with other foods
When drinking beer, if it is paired with spicy, greasy or cold food, it may increase the burden on the gastrointestinal tract and cause diarrhea. For example, beer paired with barbecue, hot pot, etc. can easily cause indigestion.
| Food that is not suitable with beer | Possible symptoms |
|---|---|
| spicy food | Burning sensation in the intestines, diarrhea |
| greasy food | Indigestion, bloating |
| Raw and cold food | Gastrointestinal cramps, diarrhea |
4. Personal physical reasons
Some people are allergic or intolerant to certain ingredients in beer, such as yeast, malt or alcohol. This group of people are prone to allergic reactions such as diarrhea and rashes after drinking beer.
| Constitution type | Possible symptoms |
|---|---|
| alcohol intolerance | Flushing, rapid heartbeat, diarrhea |
| yeast allergy | Bloating, diarrhea, rash |
| malt intolerance | Gastrointestinal discomfort, diarrhea |
