What is loss of taste?
Loss of taste is a common symptom of gastroesophageal reflux disease (GERD), salivary gland infection, sinusitis, poor dental hygiene, or even certain medicines. The medical term for a complete loss of taste is ageusia. A partial loss of taste is called dysgeusia. Loss of taste is caused by interruption of the transfer of taste sensations to the brain, or by a problem with the way the brain interprets these sensations. Although taste problems are common, complete loss of taste is rare.
