How to cure anosmia?

Anosmia is a complete loss of smell. A blocked nose can stop scent molecules reaching the smell receptors, while inflammation from allergic rhinitis, a common cold or chronic sinusitis can affect airflow. Viral illnesses, including COVID-19, may alter smell even when the nose is not blocked. A head injury, nasal growth or some medicines can also be relevant.

Smell contributes strongly to flavour, so food may seem tasteless when the main problem is loss of smell. It also helps detect smoke, gas and spoiled food. Do not assume anosmia identifies one condition; the pattern and accompanying symptoms guide assessment.

Book a clinical assessment if the change is sudden, persistent or unexplained. Treatment may involve managing nasal inflammation, an infection, sinus disease or another underlying problem. Use nasal medicines only as directed, and avoid inserting objects or unapproved oils into the nose.

Smell training can be discussed with a clinician: it involves regularly and safely smelling familiar scents and noticing changes over time. Until smell returns, check smoke and gas alarms, label leftovers and ask someone else to assess food freshness. Keep meals appealing with texture, temperature and safe seasoning rather than relying only on extra salt or sugar.

Seek urgent help for loss of smell after a head injury, or when it occurs with severe headache, weakness, confusion, speech trouble or breathing difficulty. Arrange prompt advice for one-sided blockage, recurrent nosebleeds, facial swelling or a persistent change without a clear cold. A clinician may refer you for ear, nose and throat assessment.

Ask what cause best fits your symptoms, whether your medicines or nasal blockage could contribute, and whether smell training or specialist review is appropriate. Mention when the change began and whether taste, congestion or facial pain changed with it.
