Can tuberculosis be fatal? Of course, the answer is yes. Many diseases can lead to death, even a common cold can potentially result in death, let alone tuberculosis, which is an extraordinary illness. Currently, the mortality rate for tuberculosis patients is relatively low because the treatment for tuberculosis has improved significantly compared to the past. However, there are still a small number of patients who, due to untimely treatment of tuberculosis, discontinuation of medications on their own accord or non-compliance with medical advice, or who have other serious underlying diseases, may not tolerate the tuberculosis treatment. As a result, they could potentially die from adverse reactions to the tuberculosis medications.

Local symptoms of pulmonary tuberculosis

The local symptoms of tuberculosis primarily require us to understand where tuberculosis occurs. Currently, tuberculosis in the lung tissues, trachea, bronchi, and pleura are all classified as pulmonary tuberculosis. The primary local symptoms are still respiratory symptoms, with the most common being cough and expectoration. Patients with tuberculosis generally have a slow onset, with most experiencing cough and expectoration that can persist for two weeks or more. Some patients may also exhibit symptoms like blood in the sputum or hemoptysis. Additionally, some patients may experience other symptoms; for example, those with pleural involvement might have irritative cough, chest pain, and difficulty breathing, while those with tracheobronchial involvement might exhibit a prolonged irritative cough. Some patients may also develop bronchial stenosis, which can lead to difficulty breathing.

Does tuberculosis cause fever?

Does tuberculosis cause fever? The answer is definitely yes. Fever is one of the most common clinical manifestations of tuberculosis. Many tuberculosis patients experience low fevers, and a minority of patients, such as those with caseous tuberculosis or tuberculous pleurisy, may experience high fevers that can recur and persist. Moreover, tuberculosis patients may sometimes also have concurrent bacterial infections, which can cause the fever to last longer and be more difficult to control.

Symptoms of pulmonary tuberculosis

Now let me talk about the symptoms of tuberculosis. Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, which can invade many organs, with pulmonary tuberculosis being the most common. The main symptoms are respiratory symptoms and systemic symptoms. The respiratory symptoms are mainly manifested as coughing, expectoration for more than two weeks, or blood in the sputum, which are common suspicious symptoms of pulmonary tuberculosis. Generally, the cough is mild, either dry or with a small amount of mucus. When cavities form, the amount of sputum may increase, and if there is a secondary bacterial infection, the sputum may become purulent. If there is concomitant bronchial tuberculosis, it will manifest as an irritating cough. About one-third of patients will experience hemoptysis, and some may experience massive hemoptysis. If the tuberculosis lesions involve the pleura, it can manifest as chest pain. Dyspnea is more common in patients with caseous pneumonia or those with a large amount of pleural effusion. These are local symptoms. Systemic symptoms mainly manifest as fever, which is the most common manifestation, often as long-term afternoon fever, meaning it begins to rise in the afternoon or evening, drops in the morning, and then returns to normal. Some patients may also experience fatigue, night sweats, loss of appetite, weight loss, etc. Women of childbearing age may experience menstrual disorders, etc.

How long can someone with tuberculosis live?

Early detection and appropriate anti-tuberculosis treatment of tuberculosis can lead to a normal lifespan once cured. However, it is important to exercise regularly and enhance immunity, since tuberculosis may recur if the body's resistance decreases. With the increase of drug-resistant tuberculosis, treatment difficulties have intensified. If it is detected late or not treated properly and the lung damage progresses to an advanced stage, it can be life-threatening, with survival ranging from days to years. When tuberculosis involves massive hemoptysis, death can occur at any time due to suffocation or hemorrhagic shock, depending on the specific condition.
