Tuberculosis can cause hoarseness in the throat, but it is normal if there are no other triggers. First of all, after developing TB, there will be different degrees of systemic symptoms, respiratory symptoms and signs. The respiratory symptoms include cough or dry cough or only a small amount of mucus sputum or increased sputum, which may become purulent if associated with secondary infections. In severe cases, the cough may worsen, and there may be irritating choking cough with limited rales or wheezing, for example, in combination with bronchial tuberculosis. Therefore, when the cough is severe, the throat is prone to hoarseness. In addition to hemoptysis in severe tuberculosis, severe toxaemia and high fever may cause shortness of breath, and shortness of breath often occurs when there is extensive destruction of lung tissue, pleural thickening and emphysema, and in severe cases, it may be complicated by cor pulmonale and cardiorespiratory insufficiency. Therefore, tuberculosis is more harmful to the respiratory system, and a hoarse cough is one of the symptoms that may occur. However, hoarseness can also be a symptom induced by other diseases, for example, when the tumor compresses the recurrent laryngeal nerve, hoarseness may also occur, for this reason, we need to conduct a comprehensive examination to find out the cause of the disease, symptomatic treatment.
