Loss of sense of smell (anosmia) and taste (ageusia) refer to the inability to detect odors and flavors respectively. This can be partial or complete and is often caused by various factors such as viral infections, nasal congestion, head injuries, sinus problems, neurological disorders, or certain medications.

The sense of smell and taste are closely linked, and when either is impaired, it can impact the overall perception of flavors in food. Loss of these senses can affect appetite, enjoyment of meals, and even safety (as smelling danger or spoiled food becomes difficult).

If sudden or persistent, seeking medical attention is recommended, particularly if it’s accompanied by other symptoms like nasal discharge, pain, or fever. A healthcare professional, often an ear, nose, and throat (ENT) specialist, can diagnose the underlying cause and recommend appropriate treatment, which might involve addressing the underlying issue, using medications, or sensory rehabilitation exercises to help regain some degree of smell and taste function.
