When you catch a bug that causes acute infectious gastroenteritis (gastro), your stomach and intestinal tract become inflamed, causing diarrhoea, nausea, vomiting, abdominal cramping and pain. The last thing you probably feel like doing is eating.
As you recover and the inflammation dies down, your appetite will gradually return. But what should you eat? Information abounds online but it’s difficult to sort fact from fiction.
Oral rehydration therapy is a type of fluid replacement containing sodium and potassium. It is the cornerstone of treatment for gastro, especially if you’re suffering from mild to moderate dehydration.
You can buy oral rehydration solution from a pharmacy, or make it by combining water, salts and sugar. Diluted juice or lemonade (mixed as one part juice or lemonade with four parts water) can also be used, as can sports drinks, but not in young children.

Oral rehydration therapy should be favoured over plain water, as water simply doesn’t have the essential electrolytes required to maintain electrolyte balance.
