How to recover the lost smell caused by COVID-19? | Digital Trends Spanish


The condition is known as anosmia and temporarily affects the smell of 60 percent of the people who became ill with COVID-19. However, scientific studies indicate that in 10 percent of cases the condition can last for months, beyond the period of respiratory illness.

Psychologist Julie Walsh-Messinger explains that the effect could be related to the mechanism of COVID-19 that affects the sense of smell. “The common cold causes an inflammatory response in the nose that reduces the ability to smell; What makes COVID-19 unique is that in reality it is not a nasal congestion or inflammation that causes the loss of smell, but rather the virus crosses the blood-brain barrier that penetrates the nervous system, ”explained the specialist in an interview with the portal The Conversation.

The consequences are more serious than they appear, according to Walsh-Messinger. In an emergency situation, it conditions people’s ability to detect smoke or some toxic gas. Other consequences point directly to quality of life: “Food no longer tastes good because the way taste is perceived is actually a combination of smell, taste and even the sense of touch,” he says.

But, despite the fact that each case of anosmia due to COVID-19 must be reviewed by a doctor, Walsh-Messinger emphasizes that each patient can perform exercises at home to recover their smell.

How to regain smell due to COVID-19?

A group of experts from the University of East Anglia in the United Kingdom offers a series of recommendations to treat smell disturbances caused by SARS-CoV-2. “The best treatment is smell training, although vitamin A drops may also be an option to consider,” says Carl Philpott, professor of rhinology and olfactology at the same university.

And although we emphasize that the supply of vitamin A drops should be recommended by a doctor, olfactory training exercises can be performed without major problem, as they have the advantage of not having harmful effects, they do not require a prescription and can be performed at home. .

These exercises consist of smelling different scents, such as cloves, rose, lemon, and eucalyptus. However, these can be substituted with others such as orange, nutmeg, ground coffee, coconut or vanilla.

The Fifth Sense portal offers a specialized guide that includes detailed diagnostic tests. Nevertheless, It’s only available in English.

Experts detail that this kind of exercise stimulates the renewal of specialized nerve cells for smell, which are attacked by COVID-19. However, they remember that those who experience a prolonged loss of smell should seek medical advice.
