What should you know about loss of salt taste?

Taste depends on signals from the tongue and the sense of smell. A blocked nose from a common cold can make food seem bland. COVID-19 can present with altered taste, and some people experience continuing changes after the infection, sometimes described as Long COVID. Dry mouth, oral irritation, dental problems, smoking and medicine effects can also alter flavour. Loss of salt taste does not by itself show which condition is responsible.

Notice whether sweet, sour, bitter or savoury flavours have changed too. A metallic taste, reduced smell, mouth soreness or difficulty eating gives a clinician useful context.

Keep a brief record of when the change started, recent infections, nasal symptoms, mouth dryness and medicines. Continue balanced meals and check food freshness by date and appearance rather than taste alone. Avoid adding large amounts of salt to compensate; use herbs, spices or textures for interest. Drink fluids if your mouth feels dry, and arrange a routine review if the change persists or affects appetite.

Seek urgent help for trouble breathing, facial swelling, inability to swallow fluids, sudden weakness, confusion or signs of severe dehydration. Arrange prompt assessment if taste loss follows a head injury, comes with severe headache or neurological changes, or makes it difficult to eat and drink. A routine appointment is suitable for persistent or unexplained alteration.

Could congestion, COVID-19, dry mouth or a medicine explain this change? Has my sense of smell changed as well? Should my mouth, nose or medicines be reviewed? How can I maintain nutrition while flavours are altered? When should I arrange follow-up?
