Understanding Diarrhea

Diarrhea is a common digestive disorder characterized by frequent, loose, and watery bowel movements. It can be acute, lasting a few days, or chronic, persisting for weeks or longer. While diarrhea is often a symptom of an underlying health condition or dietary indiscretion, it can also result from infections, medications, or other factors affecting the digestive system.

Causes of Diarrhea

1. Viral Infections: Viruses such as norovirus, rotavirus, and viral gastroenteritis can cause acute diarrhea, often accompanied by symptoms like nausea, vomiting, and abdominal cramps.

2. Bacterial Infections: Bacteria such as Escherichia coli (E. coli), Salmonella, and Campylobacter can contaminate food or water and lead to bacterial gastroenteritis, resulting in diarrhea, fever, and dehydration.

3. Parasitic Infections: Parasites like Giardia lamblia and Cryptosporidium can cause diarrhea, particularly in areas with poor sanitation or contaminated water sources.
