Diarrhea can have many causes. Common reasons for diarrhea include infections caused by viruses, bacteria, or parasites; food poisoning; food intolerances such as lactose intolerance; side effects of medications (including antibiotics and cancer treatments); and digestive disorders like irritable bowel syndrome, Crohn's disease, or celiac disease. It may also result from anxiety or stress, surgery on the digestive organs, or consuming artificial sweeteners. Acute diarrhea is often due to infections like viral gastroenteritis or food poisoning, while chronic diarrhea can be caused by ongoing medical conditions or long-term medication use.
In short, diarrhea occurs when the intestines do not absorb enough water or secrete too much fluid into stool, causing loose and frequent bowel movements. If diarrhea is severe, persistent, or accompanied by other symptoms, it is important to consult a healthcare provider for an accurate diagnosis and appropriate treatment.
