Dysgeusia, also known as parageusia, is a distortion of the sense of taste. Dysgeusia is also often associated with ageusia, which is the complete lack of taste, and hypogeusia, which is a decrease in taste sensitivity. [1] An alteration in taste or smell may be a secondary process in various disease states, or it may be the primary symptom.
Hypogeusia tied to oral cancer and tumors can affect sweet, sour, salty, and bitter tastes, but bitter taste hypogeusia occurs significantly more often compared to the rest of the tastes. Inhibition of gustatory papillae found in the base, often due to oropharyngeal tumors, is thought of to be the cause of this.
Ageusia (from negative prefix a-and Ancient Greek γεῦσις geûsis 'taste') is the loss of taste functions of the tongue, particularly the inability to detect sweetness, sourness, bitterness, saltiness, and umami (meaning 'savory taste'). It is sometimes confused with anosmia – a loss of the sense of smell.
British chefs Ryan Riley and Kimberly Duke, for example, used their experience at Life Kitchen — a U.K.-based school cooking school designed to help cancer patients — to create a recipe book ...
In some people, COVID-19 causes people to temporarily experience changes in how food tastes (dysgeusia or ageusia). [59] [60] Changes to chemesthesis, which includes chemically triggered sensations such as spiciness, are also reported. As of January 2021, the mechanism for taste and chemesthesis symptoms were not well understood. [60]
Anosmia is the inability to perceive odor, or in other words a lack of functioning olfaction.Many patients may experience unilateral or bilateral anosmia. A temporary loss of smell can be caused by a blocked nose or infection. In contrast, a permanent loss of smell may be caused by death of olfactory receptor neurons in the nose or by brain injury in which there is damage to the
Even though the causes of dysosmia are not yet clear, there are two general theories that describe the etiology: the peripheral and central theories. In parosmia, the peripheral theory refers to the inability to form a complete picture of an odorant due to the loss of functioning olfactory receptor neurons.
Pain and loss of taste perception makes it more difficult to eat, which leads to weight loss. Ulcers may act as a site for local infection and a portal of entry for oral flora that, in some instances, may cause septicaemia (especially in immunosuppressed patients). Therefore, oral mucositis can be a dose-limiting condition, disrupting a patient ...
