Clinical Information

Frequent bowel movements with loose and watery stools characterize diarrhea. There are two types: acute and chronic. Acute diarrhea typically lasts 1 to 2 days, while chronic diarrhea persists for longer, exceeding 3 to 4 weeks.
The causes of diarrhea vary depending on its type. Acute diarrhea can be triggered by viral, bacterial, or parasitic infections, food intolerances, intestinal diseases, medications (as a side effect), or surgery. On the other hand, chronic diarrhea may be attributed to conditions like inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS).
In addition to watery stools and increased bowel movements, patients may experience nausea, bloating, abdominal pain, cramping, and dehydration as common symptoms.
Dehydration is a high-risk concern for patients with diarrhea. Diagnosing the condition involves a physical examination and urine, blood, and stool tests. Imaging tests, colonoscopy, and sigmoidoscopy may also be performed.
The treatment approach focuses on resolving dehydration and addressing the underlying cause through medications and other appropriate therapies.

Synonyms Include:

Functional diarrhea
