Diarrhoea is a natural bodily response to eliminate harmful germs, typically lasting a few days to a week. It can be accompanied by fever, nausea, vomiting, abdominal cramps, dehydration, and occasionally rashes. The most common causes of diarrhea in children are viral infections like rotavirus, bacterial infections such as salmonella, and, although rare, parasitic infections like giardia. Viruses are the primary culprits, often causing loose stools, along with symptoms like vomiting, stomachache, headache, and fever.

Food poisoning is another common trigger of diarrhea in children, with symptoms appearing rapidly, potentially including vomiting, and usually resolving within 24 hours. Other underlying factors contributing to diarrhea in children include irritable bowel disease, Crohn's disease, ulcerative colitis, food allergies, and celiac disease. If you're uncertain about the cause of your child's diarrhea, it's advisable to consult a doctor.

Dehydration is a significant concern when dealing with diarrhea in children. Mild cases generally do not cause significant fluid loss, but moderate to severe diarrhea can result in dehydration. Severe dehydration can have serious consequences, including seizures, brain damage, and even death. It's crucial to be aware of signs indicating dehydration. If your child experiences dizziness, lightheadedness, a dry and sticky mouth, dark yellow urine or reduced urine output, lack of tears when crying, cool and dry skin, or lack of energy, it's important to contact your doctor.
