Diarrhea after drinking coffee

Nowadays, many people like to drink coffee, especially those who like to stay up late. Coffee is not only delicious, but also has the effect of relieving fatigue and refreshing. Therefore, many people regard coffee as their essential drink, but many people experience adverse reactions such as diarrhea after drinking coffee. So, what causes diarrhea after drinking coffee? Here are some reasons why drinking coffee can cause diarrhea.

Drinking coffee on an empty stomach

Caffeine stimulates the secretion of gastric acid. If you drink it on an empty stomach, it will irritate the stomach, easily damage the stomach, and affect the digestion and absorption of gastrointestinal function. Especially if you do this for a long time or have a bad stomach, it may induce gastric ulcers, causing stomach pain and diarrhea. Especially in the morning, drinking coffee on an empty stomach is most likely to cause diarrhea and stomach pain.

Drinking too much coffee

Coffee can promote gastrointestinal motility and accelerate gastrointestinal digestion. For most people, coffee has the effect of stimulating bowel movements. Therefore, if you drink too much coffee, it will over-stimulate your stomach and intestines, which will increase the urge to defecate and may cause diarrhea.

Stomach problems

Coffee can stimulate the secretion of gastric acid. If you have a bad stomach, chronic enteritis, gastroenteritis or other gastrointestinal diseases, drinking coffee will stimulate the gastric mucosa and promote the secretion of gastric acid, which may induce gastrointestinal diseases and cause diarrhea.

Drinking expired coffee

Another reason for diarrhea after drinking coffee may be that you drank expired and spoiled coffee, or the coffee was not stored well and has been contaminated in advance. Because coffee is slightly bitter, it is not easy to be discovered. Spoiled coffee will breed a large number of pathogens and molds, which will irritate the stomach and intestines and cause diarrhea after the human body drinks it.

Allergic to coffee

If you get diarrhea as soon as you drink coffee, it is likely that you are having an allergic reaction to coffee, which is medically known as "enterogenic allergy." Theoretically, the human body may have an allergic reaction to any substance, and allergies are not just itchy skin. Some people do not have skin damage, but experience symptoms such as abdominal pain and diarrhea. Just avoid allergens and don't drink coffee and you'll be fine.

Can I drink coffee if I have diarrhea?

Can't.

Some people say that coffee contains tannic acid, which has a certain astringent effect and can stop diarrhea, so it is good to drink coffee when you have diarrhea. In fact, drinking coffee when you have diarrhea may actually aggravate the diarrhea because the caffeine in coffee can stimulate the stomach and intestines, increase the secretion of gastric acid and stimulate diarrhea. In addition, coffee has a diuretic effect, which can promote the excretion of water in the body and aggravate diarrhea. Therefore, you should not drink coffee when you have diarrhea.

If the diarrhea is caused by irritation, stop eating anything and drink some warm salt and sugar water. The diarrhea will stop after the caffeine is completely metabolized.

2. If it is mild lactose intolerance, the diarrhea will stop after the lactose is completely excreted. Just drink some warm salt water to replenish the metal ions in the water.
