Hey, I'm really worried about my dad. He's been dealing with type 2 diabetes for a while now and recently, about 3 months back, he got diagnosed with pulmonary tuberculosis. He didn't tell anyone in our family because he thought it was just a regular cough and cold. But when things didn't get better, we had him tested, and it turned out to be TB. The chest X-ray and CT scan show a significant infection in both his lungs, with consolidation and cavitation, but thankfully no pleural or pericardial effusion. Now he's also got pneumonia because of all this. He's been on DOTS treatment for the last 10 days, but he's still coughing up phlegm. I'm anxious to know when we might start seeing some improvement in his condition. Could you shed some light on this?

it atleast will take 2-3 months to improve his condition, but you should continue DOTS for 6 months
