12 Symptoms of Tuberculosis

Tuberculosis has been a significant health concern for centuries, and while advancements in medical science have led to improved treatments, the disease still poses a threat. It’s essential to be aware of the symptoms, as early diagnosis can prevent the spread of the infection and aid in better recovery.

Frequent Coughing

One of the primary symptoms of TB is persistent coughing. If you have a cough that lasts for more than three weeks, it could be an indication of tuberculosis. This cough might start off dry but later produce sputum or phlegm.

Chest Pain

Chest pain is another common symptom of TB. It can range from mild discomfort to severe pain, often increasing when coughing or breathing deeply. This pain occurs due to the inflammation of the lung tissues.

Coughing Up Blood

Coughing up blood, also known as hemoptysis, is a concerning symptom of advanced tuberculosis. This occurs when the infection damages the lung tissues or blood vessels, causing blood to mix with mucus.

Unintentional Weight Loss

Unexplained and rapid weight loss is a sign that the infection is affecting your overall health. TB can suppress appetite and lead to weight loss, which, if left untreated, can become severe.

Fatigue and Weakness

Tuberculosis can cause persistent fatigue and weakness. The infection taxes the body’s immune system, leaving individuals feeling exhausted even after minimal physical activity.

Fever and Chills

Fever and chills are the body’s response to infections. If you experience a prolonged fever that isn’t responding to common treatments, it could be a symptom of TB.

Night Sweats

Experiencing severe night sweats, to the point where your clothes and sheets are soaked, is a distinctive symptom of tuberculosis. These night sweats are often accompanied by fever.

Loss of Appetite

Tuberculosis can lead to a significant loss of appetite, resulting in reduced food intake. This contributes to the weight loss commonly associated with the disease.

Difficulty Breathing

As TB progresses, it can cause shortness of breath and difficulty breathing. This occurs as the infection damages lung tissues, reducing their capacity to exchange oxygen and carbon dioxide effectively.

Persistent Hoarseness

TB can affect the vocal cords, leading to persistent hoarseness or changes in the voice. If you notice changes in your voice that last for weeks, it’s essential to consult a medical professional.

Swollen Lymph Nodes

Lymph nodes, especially in the neck, can become swollen and tender due to the body’s immune response to the TB bacteria. These swollen nodes are often painless but can be a sign of infection.

Body Aches and Pains

Generalized body aches and pains are common with many infections, including tuberculosis. The body’s inflammatory response to the infection can lead to muscle and joint discomfort.


Recognizing the symptoms of tuberculosis is vital for early diagnosis and effective treatment. If you or someone you know is experiencing any of these symptoms, it’s important to seek medical attention promptly. Early intervention can help prevent the spread of TB and improve the chances of a full recovery.
