Diarrhoea

What is diarrhoea?

  • It’s when you keep passing loose, watery stools multiple times a day
  • Can be mild (lasts 1-2 days) or chronic (more than 3-4 weeks!)
  • It happens when your body tries to flush out something bad like germs, spoiled food, or a stomach bug.

Causes of diarrhoea?

  • Germs: Viruses (like rotavirus), bacteria (Salmonella, E. coli), and parasites
  • Food intolerance: Some people struggle with milk (lactose intolerance)
  • Bad water or contaminated food
  • Certain medications – Some antibiotics can upset your gut

Symptoms?

  • Stomach cramps and bloating 
  • Frequent watery stool
  • Feeling weak and dizzy 
  • Nausea and vomiting 
  • Dehydration (dry mouth, headache, light-headedness) 

How do doctors know what’s causing your diarrhoea?

  • Asking questions: What did you eat? How long has it lasted?
  • Blood and urine tests: To check for infections.
  • Stool test: To find bacteria or parasites.
  • Food tests: To see if certain foods are the problem.
  • Scans and camera check: For serious cases.

How to stop it?

  • Drink plenty of fluids (ORS, coconut water, or light soup)
  • Avoid dairy & greasy foods while recovering
  • See a doctor if it lasts too long or you feel weak
