SLU Hospital pulmonologist responds to claims that COVID will ruin your lungs


ST. LOUIS – We know COVID has a negative effect on the lungs, but the long-term damage could be worse than we thought. One doctor in Texas claims x-rays of COVID lungs look worse than the lungs of smokers.

Dr. Ravi Nayak, the interim chairman and professor of internal medicine and director of the division of pulmonary at SLU Hospital, says that’s not necessarily true. They really only expect to see lung damage in patients who end up in the ICU and on a ventilator

“It is a wrong notion for your viewers to think if they develop COVID they are going to have bad lungs or bad lung function,” he said. “It all depends on what part of the body is affected due to COVID and if they have severe lung disease requiring ICU admission then they can expect to have some impact on their lung function.”

He shared these x-rays of a normal lung and one of a patient with severe COVID. Nayak said this is the type of patient where they could expect to see some long term lung scarring.

But what if you had a less severe case of COVID? Nayak says your lungs should heal well and look pretty healthy.

Nayak says the best thing you can do for your lungs if you have had COVID is exercise, wear your mask, social distance, and get vaccinated when it’s available.

Our news slogan is: “Coverage You Can Count On.” We quite frankly are too busy to worry about who gets the credit. Our main concern is serving the viewer.

We go where the stories take us. Whether it be Washington, D.C when a Belleville man opened fire during a congressional baseball game practice or to Puerto Rico where local Ameren crews restored power after more than 5 months in the dark.

But our early morning crew also knows how to have some fun! Our strong commitment to the communities we serve is highlighted with our Friday neighborhood shows.

Our investigative unit consists of three reporters. Elliott Davis focuses on government waste, Chris Hayes is our investigative reporter, and Mike Colombo is our consumer reporter. They work in unison with the news department by sharing resources and ideas.

We continue to cover breaking news aggressively and relied on our seasoned journalists to make a difference with the stories we covered. The shooting of Arnold Police Officer Ryan O’Connor is just one example of that. Jasmine Huda was the only reporter who had exclusive access to the O’Connor family during his amazing rehabilitation in Colorado.
