Tuberculosis (TB): Symptoms

Although tuberculosis (TB) is most frequently associated with symptoms involving the lungs—because the disease most often affects the lungs—it can affect any organ of the body. The disease can cause a variety of symptoms.

The usual symptoms of TB include:

• Fever
• Night sweats
• Cough
• Loss of appetite
• Weight loss
• Blood in the sputum (phlegm)
• Loss of energy
