About this symptom
Nausea and vomiting can accompany a transient stomach upset, infection, medication effects or conditions requiring urgent care. Their severity, duration and associated symptoms matter more than assigning the label gastritis without assessment.
What this topic means
Vomiting is a symptom, not a diagnosis. Possible causes include gastrointestinal illness, medicines and disorders outside the digestive tract. A recurrent or persistent pattern deserves evaluation, particularly with weight loss or reduced fluid intake.
When to seek medical advice
Record how often vomiting occurs, whether it follows meals, whether liquids remain down, associated abdominal pain, fever, diarrhoea, reflux, dizziness and changes in urine output. These details help determine dehydration risk and the urgency of assessment.
Options and limitations
Gastroscopy may help when there is concern for structural disease or bleeding, but it is not required for every short-lived episode. Blood tests, other investigations or no invasive examination may be appropriate depending on the clinical picture.
Assessment and preparation
The clinician reviews onset, exposure to infection, diet, medications, existing conditions and possible pregnancy when relevant. Hydration, vital signs and examination guide any laboratory testing, imaging or a referral for endoscopy.
Treatment, risks and follow-up
Management depends on the underlying cause. Oral fluids or rehydration may be sufficient in mild cases, while other patients need medical assessment and targeted treatment. Antiemetic drugs are not suitable for everyone and can mask important changes.
When urgent help is needed
Vomiting blood or material resembling coffee grounds, green vomit with severe pain, confusion, fainting, marked dehydration or inability to retain fluids needs urgent assessment. For severe symptoms call 103 rather than arranging routine gastroscopy.

Frequently asked questions
Does ongoing nausea always mean gastritis?
No. Many digestive and non-digestive conditions can cause nausea. A clinician considers symptoms and examination findings before choosing tests.
When is gastroscopy considered?
The decision depends on duration, warning signs, suspected structural disease and individual risk rather than nausea alone.
Should I take anti-nausea medicines immediately?
Do not rely on self-treatment when symptoms are severe or unexplained. Drug selection depends on the cause, other medicines and individual risks.
Important information
A medical consultation is needed for diagnosis and treatment recommendations.
Self-treatment can be harmful to your health.
