Loss of taste or smell, known as anosmia and ageusia, respectively, refers to the diminished ability to perceive flavors or scents. This condition can occur due to various factors, including viral infections, such as the common cold or COVID-19, nasal obstructions, or neurological disorders. These senses play a crucial role in enjoying food and detecting hazards, like smoke or spoiled items. When someone experiences a loss of taste or smell, it can affect their appetite and overall quality of life. Treatment often focuses on addressing the underlying cause, and recovery may vary from person to person.
