Question

review the fifth and sixth paragraphs.
some people may think theyve lost their sense of taste if food begins to taste bland or slightly “off.” but in fact, they may have lost their ability to smell.
many things can cause smell loss. a stuffy nose or a harmless growth in the nose (called a polyp) can block air and thus odors from reaching the sensory cells. certain medications, like some antibiotics or blood - pressure pills, can alter smell, but these effects are usually temporary. your smell should come back once youve recovered or stopped the medication. but some things can cause a long - lasting loss of smell. a head injury or virus, for example, can cause a long - lasting loss of smell.
