Coughing Up a Metallic Taste: Could It Be COVID-19?
The symptoms of COVID-19, the disease caused by the novel coronavirus, have continued to evolve throughout the pandemic. Early on, the hallmark symptoms were fever, cough, and shortness of breath. However, as new variants have emerged, the most common symptoms reported by those infected have changed.
According to a recent study, the current top five COVID symptoms caused by the Omicron variant are sore throat, runny nose, stuffy nose, sneezing, and persistent cough. While a metallic taste in the mouth or coughing up a metallic taste is not in the top five, some emerging data suggests it could be a newly identified symptom of COVID-19.
What Does a Metallic Taste Indicate?
A persistent metallic or iron-like taste in the mouth has been reported by some people diagnosed with COVID-19. This unusual symptom can accompany loss of taste and smell, another common indicator of the disease. Even after taste returns, some report that foods and beverages continue to have a metallic flavor.
In some cases, those infected with the coronavirus describe coughing up sputum or phlegm that has a metallic taste. This has been documented both in mild outpatient cases as well as those hospitalized with more severe COVID pneumonia.
The origins of these metallic sensations are not entirely clear. However, its hypothesized that inflammation or sensory disruptions caused by the virus could be contributing factors. The loss of taste and smell associated with COVID has been linked to inflammation of the oral cavity, nasal cavity, and upper throat where smell and taste receptors are located.
When Does Metallic Taste Occur?
Based on anecdotal reports, a metallic or iron-like taste sensation seems most likely to occur in the initial acute phase of COVID-19 infection. However, theres a possibility it could linger for weeks or months as part of long COVID
