Nausea, burping, headache and fatigue

Burping with nausea can occur when swallowed air, reflux or stomach irritation affects digestion. Headache and fatigue may follow poor sleep, reduced food or fluid intake, fever or the body's response to an infection. A cold, COVID-19 or sinus inflammation can also produce headache and tiredness, sometimes with nausea. The symptom group does not identify one diagnosis by itself.

Take frequent small sips of water or an oral rehydration drink if you have been sweating, vomiting or having diarrhoea. Eat light meals when able, avoid alcohol and foods that clearly worsen burping, and rest in a cool, quiet place. Record when symptoms began, temperature if available, recent meals, medicines and travel or sick contacts. A pharmacist can help review medicines that may irritate the stomach.

Arrange medical advice if symptoms persist, repeatedly return or interfere with drinking and normal activity. Seek urgent help for a sudden severe headache, stiff neck, confusion, fainting, weakness on one side, trouble breathing, chest pain, severe abdominal pain, persistent vomiting or signs of dehydration. Fever with a rapidly worsening illness also warrants prompt assessment.

Ask whether you need testing for infection, dehydration or digestive causes, and which pain or nausea treatments fit your health conditions and current medicines.
