What Causes Diarrhea?
4. Bacterial Infections
If we are not careful with how we store and prepare our food and water then bacteria may be able to contaminate it. Most of these bacteria will be harmless, but some can make us rather ill. Bacterial infections of the digestive system are most common in parts of the world where hygiene and sanitary conditions are poor.
E Coli and salmonella in particular are notorious for causing diarrhea, while Clostridium difficile is another common culprit. Bacterial infections will sometime be serious and hospitalization can be necessary in severe cases. They can even result in fatalities in some cases, although treatment is usually available.
