Covid Taste & Smell Disorders

Post COVID-19 Conditions

Different Types of
Taste and Smell Disorders

Anosmia: This refers to the total loss of the sense of smell. Individuals with anosmia cannot detect any odors, making it difficult for them to enjoy food or detect potentially harmful smells, such as smoke or spoiled food.

Agnosia: While people with agnosia can detect odors, they find it challenging to categorize or differentiate between them. This means they may not be able to recognize or distinguish between familiar smells.

Ageusia: This condition denotes a complete loss of taste. Affected individuals cannot differentiate between sweet, salty, sour, bitter, or umami tastes, often impacting their appetite and enjoyment of food.

Cacosmia: People with cacosmia perceive normally pleasant or neutral smells as foul or offensive. This distortion can be particularly distressing, as everyday scents become intolerable.

Dysgeusia: This is characterized by a distorted sense of taste. Commonly enjoyed flavors may be perceived as unpleasant or unusual, affecting dietary choices and appetite.

Dysosmia: While individuals with dysosmia can detect smells, their ability to correctly identify them is impaired. A familiar scent, like that of a rose, may be wrongly identified as something entirely different.

Heterosmia: This condition presents as an inability to differentiate between specific odors. Even though people can detect smells, they cannot distinguish between certain ones, leading to potential confusion.

Hyposmia: This refers to a reduced ability to detect odors. While not a complete loss of smell, it can diminish the richness of sensory experiences and pose safety risks if strong odors like gas leaks aren’t detected.

Hypogeusia: People with hypogeusia have a diminished sense of taste. While they can still taste to some extent, the intensity and richness of flavors are muted.

Parosmia: With parosmia, the perception of smells is altered, usually in an unpleasant way. For instance, the scent of fresh flowers might be perceived as rotten or foul. This can make many daily activities, like cooking or personal hygiene, challenging due to the distorted and often off-putting scents.
