Some of the most common symptoms of tuberculosis (TB) include a cough that lasts more than 3 weeks, a painful sensation in the chest and coughing up blood or sputum from the chest. Tuberculosis is caused by a bacteria and can be spread through the air, according to the Centers for Disease Control and Prevention.
Individuals suffering from active tuberculosis may experience a variety of symptoms. These people may feel tired or experience general body weakness. Loss of appetite and sweating at night are other symptoms associated with the condition. Other symptoms include chills, loss of body weight, fever, chest pain and wet coughs.
People that have a particularly weak immune system are at a higher risk of getting tuberculosis. Those who have recently recovered from the condition may also be at risk. However, anyone exposed to the bacteria that causes TB may get infected.
The use of a stethoscope to listen to the sounds made by the lungs and physical examination of the lymph nodes are among the tests doctors may use to diagnose the condition. Sputum tests, imaging tests and blood tests may equally be used to get a conclusive result. Taking antibiotics for at least 6 to 9 months is key to treating the condition, notes Mayo Clinic.
