I am burping and feeling nausea: what could that be?

Eating quickly, chewing gum, drinking fizzy drinks, or talking while eating can increase swallowed air. Acid reflux may bring a sour taste or burning behind the breastbone, while gastritis can cause upper-abdominal discomfort and queasiness. Food poisoning and gastroenteritis may add vomiting, loose stools, cramps, or fever. Less commonly, gallstones can cause pain beneath the right ribs, particularly after a rich meal. Heat exhaustion and hypoglycaemia can also cause nausea, weakness, sweating, or dizziness.

These symptoms do not identify one condition by themselves. Notice when they began, what you ate or drank, whether pain or diarrhoea is present, and whether symptoms improve with rest and fluids.

Take small, frequent sips of water or an oral rehydration drink. Choose bland foods when you can eat, and avoid alcohol, fizzy drinks, large fatty meals, and lying flat soon after eating. Slow down meals and avoid habits that make you swallow air. Do not take anti-inflammatory painkillers on an irritated stomach unless a clinician has advised you to do so.

Seek urgent medical help for severe or persistent abdominal pain, repeated vomiting, vomit containing blood, black stools, confusion, fainting, trouble breathing, chest pressure, or signs of serious dehydration such as very little urine. Arrange a clinical review if symptoms keep returning, prevent normal eating, or do not settle, especially with fever, yellowing of the skin, or unintended weight loss.

Ask what pattern best fits your symptoms, whether medicines or reflux could be contributing, and whether you need an examination or tests. Bring a list of medicines, recent meals, travel or sick contacts, and any vomiting or bowel changes.
