Loss of taste with COVID-19: what to know

A viral infection can affect taste receptors and smell pathways. Because smell contributes to flavour, food may seem bland even when the tongue can still detect basic tastes. Some people notice a reduced sense, while others experience a metallic or unpleasant taste. Loss of taste may occur with COVID-19 and can persist after the acute illness. Ongoing fatigue, difficulty concentrating, joint pain or low mood may occur with Long COVID, but these symptoms are not specific to it.

Choose foods with varied textures and safe temperatures, and use herbs or mild seasonings if they are comfortable. Maintain brushing, tongue cleaning and regular fluids. Avoid adding excessive salt or sugar to compensate for blandness. Check food dates and use smoke and gas alarms because taste and smell changes can reduce hazard awareness. Seek advice if poor appetite, weight change, low mood or difficulty eating develops.

Seek urgent help for breathing difficulty, chest pain, new confusion, fainting, or difficulty staying awake. Arrange a clinical review if taste loss is severe, persists after the infection, becomes increasingly distorted, or is accompanied by mouth pain, sores, trouble swallowing, a head injury or other neurological changes. Assessment can also help when reduced intake is causing dehydration or weakness.

Ask whether your taste change is likely linked to smell loss, whether your mouth and nose need examination, and how to support nutrition while recovery continues. Mention medicines, smoking, dental symptoms and any changes in smell.
