Like other respiratory illnesses, COVID-19, the disease affected by the new coronavirus, can trigger lasting lung damage. As we still study COVID-19, we’re understanding more regarding how it affects the lungs while people are sick and after recovery.

Panagis Galiatsatos, M.D., M.H.S., is an expert on lung disease at Johns Hopkins Bayview center and sees patients with COVID-19. He explains a number of the short- and long-term lung problems brought on by the new coronavirus.

What sort of damage can coronavirus cause in the lungs?

COVID-19, the disease caused by the new coronavirus, can cause lung complications like pneumonia and, within the most severe cases, acute respiratory distress syndrome, or ARDS. Sepsis, another possible complication of COVID-19, also can cause lasting harm to the lungs and other organs.

COVID-19 Pneumonia

In pneumonia, the lungs become filled with fluid and inflamed, resulting in breathing difficulties. for a few people, breathing problems can become severe enough to need treatment at the hospital with oxygen or maybe a ventilator.

Pneumonia that COVID-19 causes tend to require hold in both lungs. Air sacs within the lungs fill with fluid, limiting their ability to require oxygen and causing shortness of breath, cough, and other symptoms.

While most of the people get over pneumonia without lasting lung damage, the pneumonia-related to COVID-19 could also be severe. Even after the disease has passed, lung injury may end in breathing difficulties which may take months to enhance.

Acute Respiratory Distress Syndrome (ARDS)

As COVID-19 pneumonia progresses, more of the air sacs become filled with fluid leaking from the tiny

 blood vessels in the lungs. Eventually, shortness of breath sets in, and may cause acute respiratory distress syndrome (ARDS), a sort of lung failure. Patients with ARDS are often unable to breath on their own and should require ventilator support to assist circulate oxygen in the body.

Whether it occurs at home or at the hospital, ARDS are often fatal. people that survive ARDS and get over COVID-19 may have lasting pulmonary scarring.



Another conceivable intricacy of a serious instance of COVID-19 is sepsis. Sepsis happens when contamination reaches, and spreads through, the circulatory system, causing tissue harm wherever it goes.

“Lungs, heart and other body frameworks cooperate like instruments in an ensemble,” Galiatsatos says. “In sepsis, the participation between the organs self-destructs. Whole organ frameworks can begin to close down, consistently, including the lungs and heart.”

Sepsis, in any event, when endure, can leave a patient with enduring harm to the lungs and different organs.

Three Factors in Coronavirus Lung Damage

Galiatsatos notes three factors that influence the lung harm chance in COVID-19 diseases and how likely the individual is to recuperate and recover lung work:

Disease severity.. “The first is simply the seriousness of the coronavirus disease — regardless of whether the individual has a mellow case, or an extreme one,” Galiatsatos says. Milder cases are less inclined to cause enduring scars in the lung tissue.

Health conditions. Galiatsatos says, “The second is whether there are existing medical issues, for example, interminable obstructive aspiratory sickness (COPD) or coronary illness that can raise the hazard for serious ailment.” Older individuals are likewise progressively defenseless for an extreme instance of COVID-19. Their lung tissues might be less flexible, and they may have debilitated invulnerability in light of cutting edge age.

Treatment. “Treatment is the third factor,” he says. “A patient’s recuperation and long haul lung wellbeing will rely upon what sort of care they get, and how rapidly.” Timely help in the medical clinic for seriously sick patients can limit lung harm.

Can coronavirus patients lessen the chance of lung damage?

There are things patients can do to increase their chances for less severe lung damage, Galiatsatos says.

“On the off chance that you have a medical problem that puts you at higher hazard, ensure you’re doing all that you can to limit that. For instance, individuals living with diabetes, COPD or coronary illness ought to be particularly mindful so as to deal with those conditions with observing and accepting their prescriptions as coordinated.”

Galiatsatos includes that appropriate sustenance and hydration can likewise assist patients with staying away from inconveniences of COVID-19. Staying well-fed is important for overall health. Appropriate hydration keeps up legitimate blood volume and sound mucous layers in the respiratory system, which can help them better resist infection and tissue damage.”

What Coronavirus Does to the Lungs

Is COVID-19 lung damage reversible?

After a serious case of COVID-19,, a patient’s lungs can recover, however not overnight. “Recovery from lung damage takes time, Galiatsatos says.  “There’s the initial injury to the lungs, followed by scarring. Over time, the tissue heals, but it can take three months to a year or more for a person’s lung function to return to pre-COVID-19 levels.”

He takes note of that specialists and patients the same ought to be set up for proceeding with treatment and treatment.

“When the pandemic is finished, there will be a gathering of patients with new health needs: the survivors. Specialists, respiratory advisors and other human services suppliers should enable these patients to recoup their lung work however much as could be expected.”
