When is oral rehydration therapy recommended for traveller's diarrhoea?

Short answer

Oral rehydration therapy is recommended when traveller's diarrhoea causes fluid loss, especially with repeated loose stools, vomiting, thirst, or reduced urination.

This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

At a glance

Main purpose
Replace water and electrolytes lost through diarrhoea or vomiting.
Best approach
Mix the sachet exactly as directed and sip it often.

What oral rehydration therapy does

Diarrhoea removes water and dissolved salts from the body. An oral rehydration solution contains a measured balance of glucose and electrolytes that helps the intestine absorb fluid. It is useful even when appetite is poor. It does not directly stop the infection, but it helps reduce the effects of dehydration while the illness settles.

How to use it

Use a commercially prepared sachet and mix it with the exact volume of safe water stated on the packet. Sip frequently, including after each loose stool, and take small amounts if nausea makes drinking difficult. Do not add extra powder, sugar, or salt. Continue light foods when tolerated, and avoid alcohol. Infants, older adults, pregnant people, and anyone with kidney or heart problems may need tailored advice about fluid replacement.

When to seek medical care

Seek urgent medical help for confusion, fainting, extreme weakness, inability to keep fluids down, very little or no urine, blood in the stool, severe abdominal pain, or a high fever. Arrange medical advice if diarrhoea is persistent, symptoms are worsening, or the traveller has a serious long-term condition. A clinician can assess dehydration and decide whether testing or another treatment is needed.

Questions for your doctor

Ask which oral rehydration product is suitable, how much to drink for your age and health, and whether your regular medicines need adjustment during vomiting or diarrhoea.

Questions people ask

Can I use plain water instead?

Plain water helps, but an oral rehydration solution also replaces salts lost in stool and may be more suitable when losses are repeated.

What if I vomit after drinking?

Pause briefly, then try small, frequent sips. Seek medical care if you cannot keep fluids down or dehydration symptoms appear.
