Acute diarrhoea is the sudden onset of frequent, loose, or watery stools that lasts for less than 14 days. Most cases improve within 1 to 2 days.
It is a common condition and is often caused by viral infections, food poisoning, bacterial infections, certain medicines, or changes in diet.
In most cases, acute diarrhoea improves on its own within a few days without specific treatment. However, it can lead to dehydration if significant amounts of fluid are lost, particularly in young children, older adults, and people with underlying health conditions.
The main focus of treatment is usually preventing dehydration and managing symptoms while the body recovers.

Is Acute Diarrhoea a Valid Reason for a Sick Note?
Yes, acute diarrhoea can be a valid reason for a sick note if symptoms affect your ability to work safely or carry out your normal duties.
Frequent trips to the toilet, abdominal cramps, dehydration, fatigue, and associated symptoms such as vomiting or fever can make it difficult to work effectively. Time away from work may also help prevent the spread of infectious causes of diarrhoea.

Frequently Asked Questions
How Long Does Acute Diarrhoea Last?
Most cases of acute diarrhoea improve within a few days and resolve within 1 to 2 weeks. The exact duration depends on the underlying cause.
What Is the Most Common Cause of Acute Diarrhoea?
The most common causes of acute diarrhoea include viral gastroenteritis, food poisoning, and side effects from certain medicines. Viral infections are particularly common and often improve on their own within a few days.
How Do I Know If I Am Dehydrated?
Signs of dehydration can include increased thirst, a dry mouth, dizziness, tiredness, dark urine, or passing urine less frequently than usual.
What Should I Drink If I Have Diarrhoea?
Water, oral rehydration solutions, and other fluids can help replace lost fluids and reduce the risk of dehydration. Taking small, frequent sips may be easier if you also feel sick.

When Can I Return to Work or School?
People with diarrhoea are generally advised to stay away from work, school, or childcare settings until they have been symptom-free for at least 48 hours to help reduce the spread of infection.
How Can You Prevent Acute Diarrhoea?
You can reduce your risk by washing your hands regularly, practising good food hygiene, drinking safe water when travelling, and avoiding close contact with people who have infectious diarrhoea.
