It has been determined that people who have survived COVID-19 but have not regained their sense of smell have such a problem.
One of the most common symptoms of COVID-19 loss of smell during illness. This loss of smell, which is more intense and different from that experienced in an ordinary flu or cold, has not improved in some cases, even after months.
Currently, many people are facing the problem of permanent loss of smell after COVID-19. Imagine having an illness and suddenly losing your sense of smell… Fortunately, research has gotten to the point where it can answer what’s causing this problem.
Defeated while our bodies ‘fight’
The results of the study, which was carried out with 24 different people, including 9 people who experienced permanent loss of smell after COVID-19, were published in the journal Science Translational Medicine. Olfactory epithelial samples were taken from the people participating in the study. Examined tissues revealed that our bodies lose their sense of smell while ‘fighting’.
In the olfactory epithelial samples taken from the nose, it plays an active role in the body’s fight against infection. Large amounts of T cells detected. However, the presence of T cells damages olfactory epithelial cells in the region. So much so that the researchers observed that the inflammatory process still continues even in tissues where SARS-CoV-2 was not detected.
Tissues from participants who lost their sense of smell while the number of olfactory neurons is lowerThe researchers also observed that some neurons were able to continue to heal themselves even after T-cell bombardment. According to the research team, this is a positive observation.
Loss of smell may not return for months or even years, but there is hope for a cure.
Neurobiologist Bradley Goldstein of the research team stated his goals for the research “After these people became infected with SARS-CoV-2 why you will continue to experience permanent loss of smell for months, years. we need to understand betterWhile expressing his words, he emphasizes that the data obtained also reveals hope for treatment for people who are faced with this situation.
Goldstein also said “Modulating the abnormal immune response or repair processes in the nose of these patients may improve the sense of smell. at least partially hope you can help“He says. So it’s too early to talk about the existence of a permanent solution that will completely restore the senses…
The research team also called ‘long COVID’ and extreme tiredness, shortness of breath, and “brain fog” that makes it hard to concentrate states that there may be a similar reason behind the situation that causes symptoms such as: Further research is needed on this subject and further clarification is needed.
