How common is loss of appetite in influenza?

Influenza can make the whole body feel sore and exhausted. Fever can reduce interest in food, and a dry mouth, sore throat, or nausea may make eating less comfortable. Appetite often improves as the acute illness eases.

A reduced appetite does not establish that a person has influenza. Colds, stomach illnesses, medicines, stress, and many other conditions can also change appetite.

Take regular sips of fluid, even if you do not feel like eating. Warm drinks, soup, yoghurt, or soft foods may be easier to manage when your throat is sore. Choose small portions and stop if eating increases nausea.

Rest and follow any advice you have been given about fever or pain medicines. A pharmacist can help check whether an over-the-counter product is suitable alongside your current medicines and health conditions.

Seek urgent care for trouble breathing, chest pain, blue or grey lips, new confusion, severe weakness, or signs of dehydration. Get medical advice if symptoms are worsening after initial improvement or if you have a condition that raises your risk from respiratory infections.

Children who are unusually sleepy, refusing fluids, or working hard to breathe need prompt medical attention.

Ask whether your symptoms are consistent with influenza, whether testing or antiviral treatment is relevant, and how to manage fever safely. Mention pregnancy, long-term conditions, immune-suppressing treatment, and all medicines you use.
