What are the symptoms and signs of tuberculosis?

As previously mentioned, TB infection usually occurs initially in the upper part (lobe) of the lungs. The body's immune system, however, can stop the bacteria from continuing to reproduce. Thus, the immune system can make the lung infection inactive (dormant). On the other hand, if the body's immune system cannot contain the TB bacteria, the bacteria will reproduce (become active or reactivate) in the lungs and spread elsewhere in the body.

It may take many months from the time the infection initially gets into the lungs until symptoms develop. The usual symptoms that occur with an active TB infection are a generalized tiredness or weakness, weight loss, fever, and night sweats. If the infection in the lung worsens, then further symptoms can include coughing, chest pain, coughing up of sputum (material from the lungs) and/or blood, and shortness of breath. If the infection spreads beyond the lungs, the symptoms will depend upon the organs involved.

Comment from: 45-54 Male (Patient) Published: March 04

I used to get headache in the early morning. My Left arm stopped functioning. I had an MRI scan where a brain tumor was found due to tuberculosis. I underwent an operation and took medicines for a year.

Comment from: pank, 19-24 Male (Patient) Published: February 26

I had symptoms of cough that lasted for more than 8 months until last year before Christmas. I started to have enormously increased amounts of non-purulent sputum, two months after which, I had serious chest pains while breathing in. I had a persistent weakness and weight loss too. However, I occasionally experienced mild fever as well. During the prime of my symptomatic exhibits TB, I could also experience fluid accumulation in my left lung. I am currently undergoing treatment.
