Will tuberculosis cause coughing up blood?

Even in modern society, many people still stay away from tuberculosis when they hear about it, because tuberculosis is highly contagious. When a patient coughs, the virus in the body can be transmitted to other people through the air and saliva. Many patients with tuberculosis will experience coughing, because the lungs are closely related to human breathing. Tuberculosis will cause the entire respiratory system to become disordered. But will tuberculosis cause coughing up blood?

The main symptoms of pulmonary tuberculosis include a half-cough, a dry cough without sputum, coughing up sputum, coughing up blood, malaise, fever, fatigue, easy fatigue, and irritability. Cough caused by tuberculosis is often accompanied by coughing up blood, which may indicate that there are already more lesions in the lungs.

Tuberculosis is a chronic infectious disease and a systemic disease. Any organ in the human body can be infected with tuberculosis, with pulmonary tuberculosis being the most common. Patients with mild symptoms feel no discomfort and generally do not pay attention to it. Symptoms only appear when the disease progresses. Some people have poor resistance, and the amount of tuberculosis bacteria infected is large and the toxicity is strong, so the symptoms will be very obvious.

The main symptoms of pulmonary tuberculosis include a half-cough, dry cough without sputum. In the early stage of the disease, the sputum is not obvious, or there is a small amount of white mucus sputum. However, when the lesions expand or even cavities appear in the lungs, the amount of sputum will increase, and coughing up blood may also occur. The main symptoms of pulmonary tuberculosis also include general discomfort, fever, fatigue, easy fatigue, irritability, poor appetite, weight loss over time, and sometimes irregular menstruation in women.

Coughing up blood due to tuberculosis may be caused by the presence of multiple lesions in the lungs, or even cavities in some cases. Blood comes out of blood vessels, so bleeding will only occur when the disease affects the permeability of the blood vessel wall or directly damages the blood vessels. The amount of bleeding depends on the extent of damage to the blood vessels.

We believe that the number of lung lesions is not directly proportional to the amount of bleeding. However, if there are many lesions but the blood vessels are not damaged, there will be little or no bleeding. Of course, if there are many lesions, there will be more chances of damaging the blood vessels and causing bleeding. We often find that many patients do not know that they have tuberculosis in advance. They do not care about their cough or fever. However, when they cough and find blood streaks, blood clots, or even blood in their sputum, they truly realize that they have tuberculosis.

The above is relevant information about the main symptoms of tuberculosis. In daily life, we must be more vigilant about symptoms of coughing and coughing up blood, and seek medical examination and treatment in time.
