Understanding Diarrhea: Causes, Symptoms, and Prevention Strategies
Diarrhea is among the most prevalent health issues worldwide, impacting nearly two billion people annually. It ranges from a mild, temporary condition to a severe, life-threatening illness. Characterized by frequent, loose, and watery stools, diarrhea is often triggered by infections from bacteria, viruses, or parasites. Chronic cases may result from inflammatory bowel diseases such as Crohn’s or ulcerative colitis. Prevention includes proper nutrition and probiotics. This article explores the main causes, symptoms, and ways to prevent diarrhea effectively.
Primary causes of diarrhea
Gastrointestinal infections – The common culprit behind diarrhea is gastrointestinal infections caused by microbes like bacteria, viruses, and parasites. In many cases, bacteria like Salmonella, Shigella, Campylobacter, and E. coli are responsible for acute diarrhea, while some chronic cases lack a clear cause.
Microscopic colitis – This persistent form of diarrhea primarily affects older adults and often worsens at night.
Maldigestive and malabsorptive disorders – Conditions such as Celiac disease impair digestion and nutrient absorption, leading to diarrhea.
Persistent infections – Long-term diarrhea can result from ongoing infections, especially after travel or antibiotic use. These often involve bacteria or parasites.
Medication side effects – Certain drugs, notably antibiotics, can induce diarrhea as a side effect.
Hormonal factors – Hormonal imbalances, like carcinoid tumors or Addison’s disease, may cause diarrhea.
Gastrointestinal cancers – Tumors in the gut can lead to neoplastic diarrhea.
