Bronchitis and loss of taste

Taste and smell work together when you experience flavour. A blocked nose, thick mucus, dry mouth or throat irritation during bronchitis can make food seem bland even when taste receptors are working. Coughing and some medicines may also leave the mouth dry or unpleasant.

Common cold and COVID-19 can change taste and smell. Long COVID may be considered when these changes continue after the initial illness has otherwise settled. Loss of taste alone cannot identify the cause, so the timing and other symptoms matter.

Drink regularly, keep your mouth clean and choose foods with varied textures or mild natural flavours. Avoid smoking and check medicine leaflets for dry-mouth effects. Do not add excessive salt or sugar to compensate for blandness; use herbs or other flavours that you tolerate.

If you have respiratory symptoms, reduce close contact with others until you know whether a contagious infection is possible. A clinician or pharmacist can advise whether a nasal treatment is suitable for congestion.

Arrange medical advice if taste loss persists after congestion and coughing improve, keeps returning, or makes it difficult to eat and drink. Seek urgent help for severe breathing difficulty, confusion, fainting, or signs of dehydration such as very little urine and worsening dizziness.

Ask whether your taste change is more likely related to congestion, dry mouth, a recent infection or a medicine. Tell the clinician when it started, whether smell is also affected, what respiratory symptoms remain, and whether eating or drinking has become difficult.
