Diarrhoea is defined as the passage of three or more loose or watery stools per day, often resulting from gastrointestinal infections, malabsorption, or inflammatory conditions. It is clinically significant due to its potential to cause dehydration, electrolyte imbalances, and nutritional deficiencies, particularly in vulnerable populations such as children and the elderly. A common complication is acute kidney injury, which can arise from severe fluid loss.
