Question

Why do you lose your sense of taste when you have a cold?​

Answer 1

$\huge{\underline{\red{\rm{Answer}}}}$

Dr. Hunt says the swelling of the nose is what causes you to lose your ability to smell & taste during a cold, sinus infection, allergic reaction, etc. But, it should only be temporary.

Answer 2

When you have a cold, the swelling causes inflammation and obstruction, which impairs your smell. The flavour of food is produced only after taste is combined with a smell, so if a stuffy nose impairs your sense of smell, it will also decrease your perception of taste.
