What are smell disorders?
A smell disorder is a condition that causes a change in your normal sense of smell. Changes in your sense of smell may be temporary or permanent. Your sense of smell is so closely connected to your sense of taste that a smell disorder usually results in a change in your sense of taste as well. More than 2 million Americans suffer from some sort of permanent smell or taste disorder. Most often, such disorders are not considered serious problems. The ability to smell or taste usually diminishes gradually with age. Because the sudden loss of these senses can signal a serious problem such as a brain tumor, you should report any such change to your health care provider.
