Overview

Does it Taste like old pennies in your mouth? “Metallogeusia” is part of a superior disorder known as Dysgeusia. It is a medical condition characterized by an altered taste or an unpleasant taste sensation in the mouth. It can affect the ability to taste sweet, sour, bitter, or salty flavours or cause a metallic or foul taste in the mouth. Dysgeusia can be a temporary or chronic condition, and various factors, including medication, chemotherapy, radiation therapy, pregnancy, infections, nutritional deficiencies, and neurological disorders, can cause it.

The prevalence varies depending on the underlying cause. It is estimated that up to 80% of cancer patients who undergo chemotherapy experience dysgeusia. It is also a common side effect of radiation to the head and neck area. It is a common side effect of certain medications, such as antibiotics and antihistamines, and can affect up to 10% of people taking these drugs. It is also a common pregnancy symptom, affecting up to 25% of women during the first trimester. Pregnant women often experience dysgeusia during the first trimester. Other conditions, such as diabetes, Parkinson’s, and multiple sclerosis, can cause dysgeusia.

Dysgeusia is a relatively common condition that can significantly affect a person’s quality of life. Treatment varies with the underlying cause and may involve medication changes, nutritional support, or referral to a specialist.

What are Causes of Metallic Taste in Mouth?

A Metallic Taste in the mouth is because of various medical conditions, including gum disease, sinus infections, medications, chemotherapy, radiation therapy, and exposure to certain chemicals. Other possible causes include nutritional deficiencies, hormonal changes, kidney disease, and pregnancy. COVID-19 infection can also cause a metallic taste in the mouth. It is crucial to consult a doctor to discuss the underlying cause and receive appropriate treatment.

What Medical Conditions can cause?

A metallic taste in the mouth, or metallogeusia, can be caused by various medical conditions. Here are some of the common ones:

Sinus infections and allergies and a metallic taste in the mouth:

Infections or allergies affecting the nasal passages can cause post-nasal drip, leading to a metallic blood-like taste in the mouth.

Uremia can cause various symptoms, including a metallic taste in the mouth and vomiting, nausea, fatigue, and confusion.

COVID: 

The exact mechanism by which COVID-19 affects taste and smell perception is not well understood, but it is thought that the virus affects the cells that line the nose and mouth. These cells are responsible for detecting odours and flavours, and they can become damaged or inflamed in people with COVID-19, leading to changes in taste and smell perception.

Why does everything taste bad to me suddenly?

A sudden metallic taste in the mouth or change in taste, where everything tastes bad, can have various underlying causes. It could be due to infections, such as upper respiratory infections, sinus infections, or colds, which can cause a change in taste and make food taste unpleasant. Some medications can cause a metallic or bitter taste in the mouth, such as antibiotics, antidepressants, and blood pressure medications. Dental problems like gum disease, tooth decay, and infections can also cause a bad taste in the mouth. Nutritional deficiencies, aging, pregnancy, and neurological disorders such as Alzheimer’s, Parkinson’s disease, and MS can also affect the sense of taste.

What is the bitter taste in the mouth symptom of?

A bitter or strange taste in the mouth can be a symptom of several underlying conditions. Problems with the digestive system, such as acid reflux, gastritis, and bile reflux often cause it. These conditions can cause stomach acid to go back into the esophagus, leading to a bitter or sour taste in the mouth. Certain medications, such as antibiotics, antihistamines, and blood pressure drugs, can also cause a bitter taste as a side effect. Poor oral hygiene, sinus infections, and dental problems such as gum disease and tooth decay can also cause a bitter taste.

Why do I taste blood when I cough?

Tasting blood when coughing is a common symptom of a respiratory infection or other conditions that affect the respiratory system, such as bronchitis, pneumonia, or tuberculosis. The coughing can cause tiny blood vessels in the respiratory tract to break, resulting in the presence of blood in the saliva or phlegm that is coughed up.

Why does blood taste like metal?

Blood can taste like metal due to the presence of iron in hemoglobin, which is the protein that carries oxygen in the red blood cells. When the blood comes in contact with saliva in the mouth, the iron in the blood can create a metallic taste. Additionally, if the blood has been sitting in the mouth for some time, it can become oxidized and the iron can turn into iron oxide, which can also contribute to the metallic taste. This is why people often describe the taste of blood as metallic or coppery.
