What it's like to have no sense of taste or smell

As little as we hear about them, taste and smell disorders affect a lot of people in the US, about 10 to 15 million by some estimates.

There are variations based on the severity of the condition: hyposmia is a reduced ability to smell, parosmia is an inability to properly identify natural smells, and anosmia is the complete loss of smell. Similar names apply to taste loss, as well.

These disorders have many different causes, including head injuries, smoking, and nasal medication intake, so treatment is highly individualized.

His process involves using steroid medication to stimulate tongue receptors back into action — but it’s a pioneering methodology that doesn’t always lead to permanent results.
