Diarrhea can be caused by a variety of factors, including:
- Infections: The most common cause of acute diarrhea is an infection from bacteria, viruses, or parasites. This can be transmitted through contaminated food or water, close contact with infected individuals, or from animal or insect bites.
- Food intolerance: Some people may develop diarrhea after consuming certain foods, such as lactose in milk products or gluten in wheat products.
- Medications: Certain medications, such as antibiotics, can disrupt the balance of bacteria in the gut and cause diarrhea as a side effect.
- Medical conditions: Chronic diarrhea can be a symptom of medical conditions such as Crohn’s disease, ulcerative colitis, irritable bowel syndrome, or celiac disease.
- Other causes: Other factors that can cause diarrhea include stress, changes in diet or routine, artificial sweeteners and the use of certain supplements or herbal remedies.
It’s important to determine the cause of diarrhea so that appropriate treatment can be provided.
Diarrhea can cause dehydration, which can be life-threatening if untreated. Dehydration is particularly dangerous in children, older adults and those with weakened immune systems. If you have signs of serious dehydration, seek medical help immediately.
