What does loss of taste feel like with Long COVID?

Some people notice that sweet, salty, sour or bitter sensations are weaker, while others can detect basic tastes but not the full flavour of a meal. Foods may taste metallic, burnt, rotten or unusually bitter. Smell can be reduced or distorted at the same time, and this may change how you experience flavour. The pattern can fluctuate, so a food that tastes normal on one day may seem different on another.

A persistent taste change after COVID-19 deserves assessment, especially if it affects appetite, weight, hydration, or enjoyment of meals. It does not establish Long COVID on its own, because mouth, nasal, medication and other health problems can produce similar symptoms.

Keep a simple record of foods that taste acceptable, symptoms that change alongside taste, and how much you are able to eat and drink. Try cool or room-temperature foods, varied textures, and mild seasonings if strong flavours are unpleasant. Rinse your mouth gently and maintain regular oral hygiene. Do not use supplements or smell-training products without checking that they are suitable for you.

Arrange a primary-care review if the change is persistent or troublesome. A clinician can check your mouth and nose, review medicines, and consider whether further assessment is needed.

Seek medical advice if taste changes are worsening, prevent normal eating or drinking, or occur with mouth sores, facial weakness, severe headache or other new neurological symptoms. Get urgent help for trouble breathing, sudden confusion, fainting, or inability to keep fluids down.

Ask whether the pattern fits a post-COVID change, whether your medicines or oral health could contribute, and what support is available if meals have become difficult. Bring the date of your infection, the onset of taste change, and examples of altered flavours.
