What does tb do to the lungs?

A close family member recently tested positive for TB and I'm trying to understand the disease better. What exactly does TB do to the lungs, and how does it cause damage?

I was terrified when my cousin got TB, thinking his lungs were permanently ruined. But the doctor explained that while the bacteria cause inflammation and scarring, the lungs heal incredibly well once you complete the antibiotic course. He is completely back to normal now!

TB bacteria basically attack your lung tissue, creating small areas of inflammation called granulomas. Over time, if left untreated, this can destroy lung tissue and form cavities, leading to coughing up blood and severe breathing trouble. Get a chest X-ray done immediately if you have a persistent cough.

TB causes inflammation and reduces your lung efficiency, making you feel short of breath very quickly. Once your doctor says it is safe and your medication is underway, starting with very light daily walks can help rebuild your stamina and lung capacity slowly.

My pulmonologist explained that tuberculosis causes necrotizing granulomas, which basically means it kills patches of lung tissue. If not treated with anti-TB drugs, these patches turn into scars or cavities, permanently affecting respiratory function. Early intervention prevents this structural damage.

Haan na, TB makes the lungs very weak and causes a lot of coughing and chest pain. It can form small wounds inside the lungs, which is why some people cough up blood. But with proper government medicines, it cures completely, ho na.

From what I have tracked in health journals, TB causes pulmonary lesions and scar tissue, which can reduce your overall lung capacity and oxygen saturation. It is super important to monitor your SpO2 levels and complete the entire 6-month medicine course to avoid long-term damage.
