What is Diarrhea?
Diarrhea is a condition that involves frequent, loose, or watery bowel movements. It can be acute or chronic, depending on its duration and underlying cause. Acute diarrhea often lasts a couple of days, whereas chronic diarrhea persists for more than four weeks.
Diarrhea can lead to dehydration and nutrient deficiencies, making it crucial to identify and address the underlying cause promptly.
Common Causes of Diarrhea
Infections
Infections are a leading cause of diarrhea. These can be viral, bacterial, or parasitic:
– Viral Infections: Common viruses such as norovirus, rotavirus, and adenovirus can lead to diarrhea. Detailed information about viral infections causing diarrhea can be found here.
– Bacterial Infections: Bacteria like E. coli, Salmonella, and Campylobacter can contaminate water or food and cause diarrhea.
– Parasitic Infections: Parasites such as Giardia and Cryptosporidium can result in severe diarrhea, often contracted through contaminated water sources.
Diet
Dietary factors can also trigger diarrhea:
– Food Intolerance: Lactose intolerance and gluten sensitivity are common dietary causes of diarrhea.
– Food Poisoning: Consuming contaminated food can lead to foodborne illnesses that manifest as diarrhea.
