When to worry about loss of taste with COVID-19

COVID-19 can affect smell and taste processing, producing reduced, absent, or distorted flavour. A blocked nose, another viral illness, allergies, mouth problems, medicines, and head injury can also change taste, so this symptom alone does not identify its cause. Record when it began and note congestion, mouth dryness, fever, cough, fatigue, breathing changes, appetite, and hydration.

Rest and drink fluids regularly. Choose foods with textures, temperatures, and mild seasonings that you tolerate, while avoiding large amounts of salt or sugar to replace flavour. Keep up oral hygiene and avoid smoking or irritating fumes. Check food dates and storage rather than relying on taste to identify spoilage. If you have medical conditions affecting nutrition or hydration, ask for tailored advice.

Seek emergency help for difficulty breathing, persistent chest pain or pressure, new confusion, inability to stay awake, or blue or grey lips or skin. Get prompt advice if you cannot keep fluids down, feel faint, or become markedly weaker. For taste loss itself, arrange review if it persists after recovery, repeatedly returns, affects nutrition, or follows a head injury.

Ask whether you need testing or monitoring, how to protect nutrition, and which warning signs matter for your health. Tell the clinician when taste changed, whether smell changed too, your breathing and hydration, medical conditions, medicines, mouth symptoms, and any recent injury.
