Tuberculosis, commonly known as TB, is an infectious disease that affects the lungs. TB is spread from person to person through tiny droplets in the air. TB can turn fatal. According to the Mayo Clinic, TB kills almost 2 million people each year. Being able to recognize the symptoms and the ways they affect the body can lead to proper treatment to prevent long-term damage or a fatality.
Flu-Like Symptoms
Flu-like symptoms are a common occurrence with TB. As the body becomes infected by TB, the immune system weakens. You may experience malaise (feeling unwell), fatigue, fever, headache, night sweats or chills. Loss of appetite or unexplained weight loss can occur in severe cases of TB. Monitor these symptoms and notify your doctor if they last more than two to three days.
Respiratory Symptoms
Because TB primarily affects the lungs, a number of respiratory symptoms can develop. Mild cases typically include difficulty breathing or coughing. As the disease progresses, you may notice that you have had a cough for three weeks or more, or you may begin to cough up blood. It is important to notify your doctor immediately if there is any presence of blood. Chest pain, pain associated with breathing, and coughing are also common.
Other Bodily Symptoms
Although TB primarily affects the lungs, it can affect other parts of the body. Some patients experience problems with their kidneys and may have blood in their urine. It is not uncommon to experience back pain as a result of TB affecting the spine.
