Changes in diet, unfamiliar foods and gastrointestinal infections can sometimes result in diarrhoea, vomiting, abdominal discomfort or nausea while travelling. Many mild episodes resolve with rest and careful hydration, but some require medical attention.
One of the greatest concerns with persistent vomiting and diarrhoea is dehydration. Watch for excessive thirst, dry mouth, weakness, dizziness and significantly reduced urination. Particular attention should be given to young children, older adults and people with existing health conditions, as dehydration can affect them more rapidly.
Medical advice should be sought if you experience persistent or severe symptoms, high fever, severe abdominal pain, repeated vomiting that prevents you from keeping fluids down, blood in the stool, marked weakness or signs of dehydration. Symptoms that are worsening rather than improving should also be assessed.
Avoid automatically taking antibiotics or other prescription medication without medical advice. The appropriate treatment depends on the likely cause and severity of the illness.
If you are uncertain about your symptoms, SOS Tourist Doctor can provide an initial medical assessment and advise whether you can continue recovering at your accommodation or require further examination, testing or treatment.
