Diarrhoea is a condition when a person's stools (poop) become loose, watery, and frequent. It happens when the body's digestion process is disrupted, causing food to pass through the intestines too quickly.
Diarrhoea can be caused by viruses, bacteria, or other factors, and it usually goes away on its own after a few days. It may make a person feel sick and dehydrated, so it's essential to drink lots of fluids when experiencing
