To respond briefly, yes, TB can affect a person's kidneys. This condition is known as renal tuberculosis. Along with the general symptoms of TB, it can also lead to kidney pain.

If the infection is in the lungs, symptoms can include a coughing up of blood known as hemoptysis. Night sweats are frequently mentioned as a characteristic symptom of this condition. Weight loss, sometimes known as consumption, is also a potential sign. A chronic cough may also be found in the individual. Please keep in mind that these symptoms can also be seen in other medical conditions; additionally, a person may be infected with tuberculosis and not display these.

Many cases of TB are asymptomatic – that is, the patient does not show any symptoms. This beginning stage is known as the late period of the infection. Only about ten percent progress to an active stage in which symptoms appear. If the disease reaches this point and is left untreated, it is fatal roughly half the time. Treatment involves the use of antibiotics.
