Burping and loss of appetite: what to know

Gastritis, a peptic ulcer, or gastroenteritis may reduce appetite while causing nausea, discomfort, and extra burping. COVID-19 or influenza can suppress appetite during a wider illness. Hepatitis A may include tiredness, nausea, abdominal discomfort, dark urine, or yellow skin. Depression can affect appetite and digestion as well. Less common but serious conditions, including pancreatic cancer, can present with loss of appetite alongside other persistent changes; these symptoms alone do not establish a diagnosis.

Take small, frequent sips of water or an oral rehydration drink if nausea is present. Choose small portions of plain, nourishing food and avoid alcohol, smoking, and foods that clearly worsen discomfort. Record how much you eat and drink, your weight trend, pain, fever, bowel changes, and any new medicines. Do not stop prescribed treatment without advice.

Contact a clinician if poor appetite lasts, keeps returning, or is accompanied by weight loss, ongoing pain, fever, vomiting, diarrhoea, or marked tiredness. Seek urgent care for confusion, fainting, very little urine, severe abdominal pain, vomiting blood, black stools, or yellowing of the skin or eyes.

Ask whether you need an examination, blood tests, or stomach testing. Mention travel, sick contacts, alcohol, prescribed and non-prescribed medicines, mood changes, and any weight or bowel changes.
