common taste disorders?
The most common taste disorder is phantom taste perception: a lingering, often unpleasant taste even though there is nothing in your mouth. People can also experience a reduced ability to taste sweet, sour, bitter, salty, and umami -- a condition called hypogeusia [hy-po-GYOO-zee-a]. Some people can't detect any tastes, which is called
ageusia [ah-GYOO-zee-a]. True taste loss, however, is rare. Most often, people are experiencing a loss of smell instead of a loss of taste.
In other disorders of the chemical senses, an odor, a taste, or a flavor may be distorted. Dysgeusia [dis-GYOO-zee-a] is a condition in which a foul, salty, rancid, or
metallic taste sensation persists in the mouth. Dysgeusia is sometimes accompanied by
burning mouth syndrome, a condition in which a person experiences a painful burning sensation in the mouth. Although it can affect anyone, burning mouth syndrome is most common in middle-aged and older women.
CAUSES :
Some people are born with taste disorders, but most develop them after an
injury or illness. Among the causes of taste problems are:
Upper respiratory and middle ear infections
Radiation therapy for cancers of the head and neck
Exposure to certain chemicals, such as insecticides and some medications, including some common antibiotics and antihistamines
Head injury
Some surgeries to the ear, nose, and throat (such as middle ear surgery) or extraction of the third molar (wisdom tooth)
Poor
oral hygiene and dental problems.
