Does oral rehydration therapy treat traveller's diarrhoea?

Traveller's diarrhoea can lead to loss of water and electrolytes through frequent loose stools and vomiting. Oral rehydration solution contains a carefully balanced mix that helps the intestine absorb fluid and salts. It supports your body while the underlying infection or irritation runs its course; it is supportive treatment rather than an antibiotic.

Mix a commercially prepared oral rehydration sachet exactly as directed with safe water. Take frequent small sips, especially after each loose stool, and continue eating light foods as tolerated. Avoid mixing sachets with juice or soft drinks, and do not rely on very sugary drinks alone because they can worsen diarrhoea. A pharmacist or clinician can advise whether another treatment is appropriate for your symptoms and travel circumstances.

Seek urgent medical help for confusion, fainting, severe weakness, very little urine, inability to keep fluids down, blood in the stool, severe abdominal pain, or a high fever. Arrange medical assessment if diarrhoea persists, symptoms are worsening, or you have a condition that makes dehydration more dangerous.

Ask which oral rehydration product and mixing method suit you, how much to drink while symptoms continue, and whether your symptoms suggest an infection needing specific treatment.
