Introduction

Diarrhoea affects millions worldwide, causing not just discomfort but also significant dehydration if not managed properly. Recognized as loose, watery stools occurring more than three times in one day, it’s important to understand the root causes to effectively prevent and treat this condition.

Infectious Causes

Infectious agents are the most common culprits of diarrhoea. The introduction of foreign bacteria, viruses, or parasites into the digestive system can disrupt normal bowel function.

Bacterial Infections

• Pathogens such as E. coli, Salmonella, and Campylobacter typically cause bacterial diarrhoea.
• Contaminated food or water is often the transmission route.

Viral Infections

• Viruses such as Norovirus and Rotavirus are frequent causes, especially in children.
• Close contact environments like schools and nursing homes can quickly spread these infections.

Parasitic Infections

• Parasites like Giardia and Cryptosporidium often cause prolonged diarrhoea.
• Prevention is mainly through avoiding water sources in affected areas.

Dietary Causes

Dietary choices play a significant role. Consuming certain foods or additives can trigger diarrhoea, especially in sensitive individuals.

• Food intolerances: Lactose or gluten intolerances can lead to diarrhoea.
• Artificial sweeteners, particularly sorbitol and mannitol, can also cause diarrhoea.

Medical Conditions

Chronic conditions often manifest with diarrhoea as a symptom. Understanding these can help address recurring issues.

• Irritable Bowel Syndrome (IBS): Frequent cause of chronic diarrhoea.
• Inflammatory Bowel Disease (IBD): Includes Crohn’s disease and ulcerative colitis, often resulting in diarrhoea.

Preventive Measures

Adopting certain precautions can significantly reduce the risk of diarrhoea.

• Ensure proper hand hygiene before eating and after using the toilet.
• Drink water from safe, clean sources. Use a filter when necessary.
• Be cautious with food preparation, ensuring meats are cooked thoroughly.

Management and Treatment

Managing diarrhoea promptly can prevent complications.

• Stay hydrated with electrolyte drinks or oral rehydration solutions.
• For bacterial infections, consulting a healthcare provider for antibiotics may be necessary.
• If diarrhoea persists, seeking medical attention is crucial to rule out underlying conditions.
