Can a Common Cold Cause Loss of Taste?

Yes. Loss of Taste is a common presentation of Common Cold, and taste usually improves as nasal congestion and other cold symptoms settle. What feels like a loss of taste is often a reduced sense of smell: flavour depends heavily on aromas reaching the smell receptors in your nose. A blocked nose, swelling inside the nasal passages, or thick mucus can interfere with that pathway.

During a cold, foods may seem bland, and you may notice that you can still detect basic tastes such as sweet, salty, sour, bitter, or savoury but cannot identify flavour as clearly. This commonly follows congestion and may occur with a runny nose, sneezing, sore throat, cough, or a mild fever. The change should gradually ease as the illness resolves.

Loss of taste has other possible causes, including nasal allergies, some medicines, mouth or dental problems, and other infections. If the change started suddenly, is complete, or continues after your cold symptoms have gone, arrange a clinical assessment rather than assuming the cold is the only explanation.

Rest, drink enough fluids, and use measures that ease your congestion, such as saline nasal spray or a warm shower. Follow the directions on any over-the-counter cold medicine, and check with a pharmacist if you take regular medicines, are pregnant, or have a long-term condition. Avoid smoking and strong irritants, which can further disturb smell and taste.

Keep food safe while flavour is reduced: check use-by dates, follow normal refrigeration guidance, and do not rely on taste or smell alone to decide whether food is spoiled. Choose varied textures and temperatures if eating feels less enjoyable, and continue eating and drinking as normally as you can.

Seek urgent medical help for trouble breathing, chest pain, confusion, severe weakness, or difficulty staying awake. Contact a clinician promptly if you cannot keep fluids down, become dehydrated, develop severe facial pain or swelling, or your symptoms are getting markedly worse.

Book an appointment if loss of taste does not start improving as your cold settles, persists after the other symptoms have cleared, keeps returning, or is accompanied by neurological symptoms or significant mouth changes. A clinician can review your symptoms, medicines, nose and mouth, and decide whether further testing is needed.

You could ask: Could nasal congestion explain my change in taste? How long should I watch for improvement? Could any of my medicines or a mouth problem be contributing? Do I need an examination or testing if my sense of taste does not return?
