Tuberculosis (TB) typically affects the lungs. But in up to one-third of infected people, particularly those with HIV/AIDS, the illness also involves other areas of the body. Common sites of infection include the lymph nodes, the membranes that cover the brain (meninges), the joints, the kidneys and the membrane covering the digestive organs (peritoneum). Untreated TB can cause progressive lung damage, which can lead to inability to maintain blood oxygen levels and death. With the many organs affected by TB, people often die sooner than expected related to other conditions, such as heart disease or a second different infection.

Tuberculosis is an infectious disease caused by a mycobacterium, Mycobacterium tuberculosis, also known as Koch’s bacillus. It is an indolent, chronic disease that can affect various organs of the body such as lungs, lymph nodes, liver, kidneys, among others. Its transmission occurs through the respiratory tract and the pulmonary form, in which the lungs are the primarily affected organs, is the most usual form. When left untreated, the disease can develop into a consumptive syndrome (in which the patient experiences severe weight loss, fever, loss of appetite) with reduced functionality; damage to the organs can then accumulate, eventually progressing to organ failure. In the pulmonary form, the patient may develop hemoptysis (coughing up blood), massive bleeding and respiratory failure.

The bacteria usually attack the lungs. But tuberculosis bacteria can attack any part of the body, such as the kidney, spine, and brain. If not treated properly, tuberculosis disease can be fatal. Tuberculosis disease was once the leading cause of death in the United States.

Tuberculosis is a most common cause of lung morbidity. It affects breathing for a longer period. By decreasing the immunity of our body, TB causes other infection to occur. Untreated TB may affect vital organs like brain, heart, kidney.
