What do loss of smell and taste suggest?

Infammation smells : Nasal inflammation can cause anosmia (loss of sense of smell). Since most of taste is related to smell they often are both affected. Although medications can usual decrease nasal symptoms anosmia may persist. Oral or injectable steroids often temporarily restore taste and smell, but side effect Prohibit their use.

2 possibilities: Loss of smell is often if not always associated with the loss of taste, even though the taste nerve fibers are functional. The two possibilities for anosmia (loss of smell) are blockage of the roof of the nose by a mass or inflammation, and degeneration of the olfactory nerve, the nerve of smell. I would first check with an ENT doctor to determine blockage and then a neurologist.
