The coronavirus left many side effects in its wake among the people who suffered it: loss of smell and taste, conjunctivitis, skin lesions in the form of hives or rapid and massive hair loss were some of the medical situations that those people who recovered from the COVID.
Among these consequences produced by the disease, the loss of smell and taste generated sequelae that, months later, still persist in men and women recovered from the coronavirus.
Many patients are suffering from a disorder called “parosmia “, a phenomenon that causes smells and tastes to distort, that they begin to smell “strange things”.
Partial or complete loss of smell, or anosmia, is usually the first symptom of the coronavirus. Loss of taste, or ageusia, can also be a symptom.
The sense of taste is directly impaired.
“Everything smells like a corpse in the process of decomposing”, “no matter what it smells, the smell is always like rotten citrus”, “it smells of rotting food and dirty diapers”, “I can’t stand opening the refrigerator and coffee tastes like gasoline. ”Many testimonies are added on social networks and tell the suffering of those people who, months after overcoming the COVID, they still cannot regain neither taste nor smell.
Before the pandemic, the disorder was linked to nervous system or psychiatric diseases.Today, scientists can pinpoint more than 100 possible reasons for loss and distortion of smell, including viruses, sinusitis, head trauma, chemotherapy, disease Parkinson’s and Alzheimer’s disease.

But now it is one of the most characteristic side effects of COVID. While the experts search for a cure, those who suffer from it feel that they will never be able to recover.
In 2020, parosmia became remarkably widespread, frequently affecting coronavirus patients who lost their sense of smell and then largely regained it before they began to experience distortions in their sense of taste and smell.
In June of last year, an article published in Chemical Senses magazine, based on questionnaires, revealed that the 7% of the patients who suffered from COVID-19 experienced smell distortion.

A subsequent study based on an online survey in the UK revealed that 6 months after the onset of COVID-19, 43% of patients who had initially reported losing their sense of smell reported experiencing parosmia, according to an article from the Rhinology publication. This emergence occurred an average of 2.5 months after the patients lost their sense of smell, the article reported.
There are several theories about the origin of this situation. One conjecture is that it is the result of an inflammation in the olfactory cleft, another brand hypothesis that it is the product of an infection and the third theory indicates that the virus affects the olfactory neurons in the brain and they stop processing the related information correctly with the smell of things.
For those suffering from parosmia, for a few months life is never the same. The bad smell of food causes them to lose their appetite and stop drinking fluids. In many cases, they cannot bear the smell of their loved ones and are overwhelmed by going outside, leading to isolation at risk of depression.

Treatment, for now, consists of medications to relieve symptoms and, as a last resort, surgery to remove the receptors from the nasal cavity. Doctors ask for patience, as cells regenerate and symptoms disappear. At Stanford University they have already started studies with people who suffer from evil and urgently seek solutions. Covid parosmia has become a phenomenon on social networks.
