Symptoms, causes and key details

Stomach infections, reflux, migraine, medicines, pregnancy, vestibular conditions and metabolic disorders may cause nausea. Pain location, fever and vomiting provide valuable clues.

Assessment and practical next steps

Sip fluids frequently and temporarily avoid large, fatty meals. Keep a record of duration, medications and associated symptoms such as fever or diarrhoea.

When is urgent help needed?

Vomiting blood, intense abdominal pain, dehydration, confusion or new neurological symptoms require urgent medical assessment.
