This is what coronavirus does to your body – from lung scarring to liver damage
IT'S becoming increasingly clear coronavirus is here to stay and many people are continuing to suffer after recovering from the virus.
Many patients who have survived Covid-19 are suffering with "long-Covid" and many have been left with debilitating conditions.

Doctors say that the deadly disease can have a long-term impact to a patients' health, causing lasting damage to their whole body.
And it's not just their lungs that are affected by the lethal disease, it's also other vital organs and bodily systems.
It was previously reported that 75 per cent of patients are still suffering more than three months after recovering from Covid-19.
Symptoms experienced by those who have recovered include breathlessness, muscle aches and excessive fatigue.
The key symptoms of the virus include a new and persistent cough, a high temperature and a loss of taste and smell - but those who have long-Covid are suffering a variety of conditions.
Experts have indicated psychosis, fatigue, loss of eyesight and mobility issues are among the wide-ranging conditions that have been identified in those who have previously contracted the virus.
Here, we take you through some of the long-term effects of coronavirus...
1. Lung scarring
As many people will already know, coronavirus is a respiratory disease that has a huge impact on the lungs.
Many Covid-19 patients develop a form of respiratory failure called acute respiratory distress syndrome (ARDS), which requires patients to receive oxygen via a ventilator.
suggest ARDS can significantly diminish people’s quality of life, even after they’ve recovered, as it leaves irreversible scarring in the lungs.
Khalilah Gates, a pulmonologist and assistant professor of pulmonary, critical care and medical education at Northwestern University’s Feinberg School of Medicine, told : “We know from influenza and ARDS and other causes of ARDS that, based on the severity of the acute illness, there can definitely be long-term consequences from the inflammation and scarring."
She added that this can lead to “irreversible lung damage and lung impairment that can lead to chronic respiratory symptoms and need for oxygen long-term.”
2. Liver damage
A from China previously suggested that many people who have been infected with coronavirus can develop liver damage.
Scientists analysed the blood test results of 34 Covid-19 patients over the course of their hospitalisation.
And their readings revealed that the recovered patients continued to have impaired liver function.
And that was the case even after two tests for the live virus had come back negative and the patients were cleared to be discharged.
3. Weakened heart
Covid-19 is also putting extreme stress on people’s hearts.
Scientists from Harvard University have dubbed the deadly disease “
They revealed that the inflammation and high fevers brought on by the coronavirus weaken the heart and increase the risk for cardiac abnormalities like blood clotting.
Len Horovitz, an internist and pulmonary specialist at Lenox Hill Hospital in New York, expects that some people who battled a severe bout of Covid-19 may go on to develop a disorder of the heart that affects the rate or rhythm at which the heart beats, known as heart arrhythmias.
He added that they could also develop congestive heart failure and myocarditis or pericarditis (inflammation of the heart muscle).
4. Impaired mobility
Many Covid-19 patients will be left battling with cognitive and physical function in the weeks and months after leaving the hospital.
This is common in patients admitted to intensive care units because bed rest can take a serious toll on the body and people can experience muscle breakdown quickly when they’re stuck in a bed in the hospital.
A found that for each day a person was on bed rest, their muscle strength dropped from three per cent to 11 per cent over the following months and years.
Medics fear that the impact coronavirus has on mobility may be worse as the treatment recovery programmes in hospitals usually used to help patients get mobile again are not being delivered.
And on top of that, it takes coronavirus patients a long time to recover - usually about two weeks.
5. Continued shortness of breath
Doctors say coronavirus patients are likely to have persistent shortness of breath, even after they've recovered.
They say most of those who had severe acute respiratory syndrome (SARS) had shortness of breath for one month after infection - and this is likely to be the same for Covid-19 patients.
Dr Steven Berk, executive vice president and dean of Texas Tech Health Sciences Center School of Medicine, told : "Those with SARS pneumonia had shortness of breath one month after infection. Most patients improved over time...
"Those who had developed acute respiratory distress syndrome (ARDS) remained short of breath for months or for a lifetime."
6. Mental health problems
Psychiatrists say that from looking at past coronaviruses it is likely many Covid-19 patients will go on to develop mental health problems including depression and anxiety.
In fact, a study of patients discharged after suffering SARS found that more than one-third reported depression and anxiety 12 months on.
“From the original SARS outbreak in 2003, we see that psychiatric illness is the most notable long-term outcome,” said Dr. Melissa Nolan, an infectious disease expert, and professor at the University of South Carolina.
"Including post-traumatic stress disorder and depression."
In general, health experts predict that the less inflammation a patient experiences, the less long-term effects they’ll have.
As Covid-19 is a new illness, experts are still grappling to understand the disease and the long-term impacts it may have.
Researchers will need to follow patients over time, and look for changes and in their hearts and lungs and other key organs, to see if the damage is long-lasting or if the body is able to make a swift recovery.
