What is Metallic Taste, also known as dysgeusia?

Metallic taste is a taste disorder medically known as dysgeusia. It is an abnormal or impaired sense of taste, or an unpleasant alteration of taste sensation and is usually described as a persistent metallic, sour, or bitter taste in the mouth. This temporary unpleasant taste in the mouth often happens after eating pungent foods like onions, garlic or certain kinds of fish. If an altered taste continues it may be a sign of a taste disorder.

Metallic Taste Causes

There are many medical and non-medical conditions that can cause metallic taste. Here are some of the common causes:

Causes of Metallic Taste. GERD, Medications, Cancer Treatment, Infections, Allergies, and more

Metallic Taste Problems

To mask the unpleasant taste associated with dysgeusia patients often choose to eat saltier and overly sweet foods. This increased intake of sodium and sugar can cause complications and a negative impact on one’s overall health. One study showed that some patients may also start drinking more water, creating the risk of polyuria among the elderly community.

Treatment of Metallic Taste

In many cases, metallic taste may take a long time to go away or may be caused by a patient’s medication. To alleviate symptoms, patients can take a metallic taste oral rinse, called MetaQil.

What is MetaQil?

MetaQil’s scientifically designed formula alleviates metallic taste caused by chemotherapy, GERD, and a variety of medications. MetaQil gently cools the mouth and provides instant, long-lasting relief from metallic taste symptoms. It has a mild flavor and does not “sting” the mouth like an every-day mouthwash. Regular use of MetaQil can help patients return to healthy eating and adequate nutrient intake.
