Coronavirus primarily infects the lungs of infected individuals and damages the alveoli (small air sacs) and surrounding tissues, and this can lead to an outflow of fluid that is often inflamed cells and protein, causing pneumonia.
As the transport of oxygen stops, affected individuals begin to experience symptoms such as coughing and shortness of breath, and in more severe cases, pneumonia can turn COVID-19 To acute respiratory distress syndrome (ARDS)ARDS), Which is a progressive type of respiratory failure, and people with acute respiratory distress syndrome may need mechanical ventilation to help them breathe.
The survivors’ lungs recovered from the Coronavirus–
But now, according to a study from the University Radboud In the Netherlands, published by “ThehealthsiteThere has been a discussion among doctors about whether the lung of a severe Covid-19 patient can recover fully after recovery from the disease.
The study brought positive hope to those who survived a virus Covid-19 Acute, as researchers found that the lung tissue of patients who severely suffered from Covid-19 They show a good recovery within 3 months in most cases, and the results of the study are published in a journal Clinical Infectious Diseases.
Damaged lungs tend to heal over time
The study included 124 patients who had recovered from infection Covid-19 Acute, and they were divided into 3 study categories: the first group included patients who were admitted to the intensive care unit, the second group included patients who were admitted to the hospital’s nursing ward and the third group consisted of patients who could stay at home.
After 3 months, the patients were examined with a CT scan, a lung function test and more, and they found the patients’ lung tissue was recovering well, and the residual damage to the lung tissue was generally limited and was mostly seen in the patients treated in the ICU, the researcher wrote in Their study paper.
They found that the recovery patterns from a virus Covid-19 Similar to acute pneumonia or acute respiratory distress syndrome (ARDS).ARDS), And the author of the study was quoted as saying: “It is encouraging to see that the lung after Covid-19 infection shows this level of recovery.”
The good news is that the research team hardly found any anomalies in the lungs of these patients, and the most common complaints among patients after 3 months were fatigue, shortness of breath, and chest pain.
Patients recover faster if they undergo rehabilitation
Earlier in September, research presented at the International Conference of the European Respiratory Society 2020 reported that the COVID-19 They can suffer from long-term lung and heart damage, but for many, this condition tends to improve over time.
For the study, the researchers conducted follow-up visits to patients who had recovered from an infection COVID-19 Moderate to severe and requiring hospital treatment, and CT scans conducted 6 weeks after discharge showed lung damage in about 88% of these patients, but at week 12, lung damage decreased to 56%, and the researcher indicated that this improvement It indicates that the lungs have a mechanism to repair themselves.
