Can hay fever cause loss of smell?

Yes, hay fever can cause a loss of smell. This happens because the inflammation in the nasal passages can block the olfactory receptors, which are responsible for detecting smells. When these receptors are hindered, it can lead to a temporary reduction or loss of the sense of smell.

Key points:

• Hay fever leads to nasal inflammation.
• Blocked nasal passages can affect smell.
• Loss of smell from hay fever is usually temporary.
• Other factors can also contribute to loss of smell.
