How MAC lung disease progression can impact the lungs
MAC lung disease may lead to lung damage over time
As progresses, it may cause damage to your lungs. This could make you feel out of breath, more tired, and make everyday life harder. That’s why it’s important to track any changes you notice in your symptoms, no matter how small.

MAC lung disease can get worse without treatment
Even when MAC lung disease is considered mild or stable, your symptoms and any lung damage could get worse if left untreated.
In one study, more than 60% (305/488) of people with untreated MAC lung disease received treatment within 3 years after diagnosis because their disease got worse.
