Taste Disorders

What are the taste disorders?
The most common true taste complaint is phantom taste perceptions. Additionally, testing may demonstrate a reduced ability to taste sweet, sour, bitter, salty, and umami, which is called hypogeusia. Some people can detect no tastes, called ageusia. True taste loss is rare; perceived loss usually reflects a smell loss, which is often confused with a taste loss.
What causes taste disorders?
Some people are born with chemosensory disorders, but most develop them after an injury or illness. Upper respiratory infections are blamed for some chemosensory losses, and injury to the head can also cause taste problems.
How are taste disorders diagnosed?
The extent of a chemosensory disorder can be determined by measuring the lowest concentration of a chemical that a person can detect or recognize. A patient may also be asked to compare the tastes of different chemicals or to note how the intensity of a taste grows when a chemical's concentration is increased.
Are taste disorders serious?
Yes. A person with a taste disorder is challenged not only by quality-of-life issues, but also deprived of an early warning system that most of us take for granted. Taste helps us detect spoiled food or beverages and, for some, the presence of food to which we're allergic. Perhaps more serious, loss of the sense of taste can also lead to depression and a reduced desire to eat.
Can taste disorders be treated?
Yes. If a certain medication is the cause of a taste disorder, stopping or changing the medicine may help eliminate the problem. Some patients, notably those with respiratory infections or allergies, regain their sense of taste when the illness resolves. Often the correction of a general medical problem can also correct the loss of taste.
Occasionally, recovery of the chemosenses occurs spontaneously.
