What Causes Bacterial Diarrhea
Bacterial diarrhea occurs when harmful bacteria invade the digestive tract. Common pathogens include Salmonella, Campylobacter, and Escherichia coli. These bacteria can enter the body through contaminated food or water, leading to inflammation and increased fluid in the intestines.
Common Symptoms and Signs
Symptoms often include frequent loose stools, abdominal cramps, nausea, and fever. Some infections may cause bloody stool or dehydration. Symptoms can appear hours to days after exposure and usually last a few days to a week.
When to Seek Medical Help
Medical attention is important if diarrhea is severe, lasts more than a few days, or is accompanied by high fever, blood in stool, or signs of dehydration. Early evaluation helps identify the cause and guides appropriate treatment. For more information on managing symptoms, visit the CDC website at CDC.gov.
