The 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 proteins, causing pneumonia.
When oxygen transport is cut off, those affected begin to experience symptoms such as coughing and shortness of breath, and in severe cases, pneumonia can turn COVID-19 To acute respiratory distress syndrome (ARDS)Acute respiratory distress syndrome), 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 have recovered from the Coronavirus
But now, according to a University study Radboud In the Netherlands, published by “ThehealthsiteThere has been a discussion among doctors as to whether the lung of a severe patient with Covid-19 can fully recover after healing from the disease.
The study brought positive hope to those who survived a virus COVID-19 Acute, as the researchers found that the lung tissue of patients suffering severely COVID-19 They show good recovery within 3 months in most cases, and the study results are published in a journal Clinical infectious diseases.
Damaged lungs tend to heal over time
The study included 124 patients who had recovered from the infection COVID-19 Acute, and were divided into 3 study categories: the first group included patients admitted to the ICU, the second group included patients admitted to the hospital’s nursing ward, and the third group consisted of patients who could stay at home.
After 3 months, patients were examined with a CT scan, lung function test, and more, and found that the patients’ lung tissue was recovering well and residual damage to lung tissue was generally limited and was seen mainly in patients treated in the ICU, the researcher wrote their study paper.
They found that the recovery models from a virus COVID-19 Similar to acute pneumonia or acute respiratory distress syndrome (ARDS).Acute respiratory distress syndrome), And the study’s author said: “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 found almost no abnormalities 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
In early September, research presented at the European Respiratory Society 2020 International Conference 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 in need of hospital care, and CT scans conducted 6 weeks after discharge showed lung damage in approximately 88% of these patients, but at week 12, lung damage dropped to 56% and the researcher indicated that this improvement indicates that the lungs have a mechanism to repair themselves.
