Whether patients with tuberculosis can drink alcohol, first of all, it is important to know that tuberculosis is a chronic infectious disease and a consumptive disease that consumes the body's calories. Drinking alcohol can affect the body's absorption of energy. Moreover, most patients with tuberculosis need to take anti-tuberculosis medication, most of which are metabolized through the liver and can cause varying degrees of liver damage. Drinking alcohol can exacerbate liver damage and reduce the effectiveness of the medication. Additionally, since there are many types of anti-tuberculosis medications for tuberculosis patients, some medications may cause adverse reactions when drinking alcohol. Therefore, all tuberculosis patients must strictly abstain from drinking alcohol during treatment.

How is tuberculosis treated?

The treatment of tuberculosis generally involves two aspects: etiological treatment and symptomatic management. Etiological treatment targets the tuberculosis bacteria with medication. Modern anti-tuberculosis chemotherapy regimens are quite mature, employing strategies such as early and combined use, appropriate dosing, regular administration, and full-course treatment, which result in a very high cure rate. Additionally, there is symptomatic management, for example, cough suppressants for patients with a cough, expectorants for those with excessive sputum, antipyretics if there is fever depending on the situation, and hemostatic drugs for patients coughing up blood, among others. The treatment of pulmonary tuberculosis is comprehensive and must be conducted under the guidance of a physician. It is crucial not to interrupt treatment casually to avoid affecting the effectiveness of the therapy, increasing the recurrence rate, and the emergence of drug resistance.

Is tuberculosis contagious?

Not all cases of tuberculosis are infectious. Some tuberculosis cases are infectious in the early stages but become non-infectious after proper treatment. Patients with open tuberculosis are highly contagious because their sputum contains tuberculosis bacilli. These bacilli can be released into the air through coughing, sneezing, laughing, or loud speaking, and can cause infection when inhaled by others. Some tuberculosis patients do not have detectable bacilli in their sputum, and their infectiousness is relatively much lower.

Does tuberculosis cause a runny nose?

Do patients with tuberculosis have a runny nose? First, we need to understand what tuberculosis is. The pathogen of tuberculosis is Mycobacterium tuberculosis, commonly referred to as TB bacillus. Its primary site of infection is the lungs, but now we also classify and manage tracheobronchial and tuberculous pleurisy under pulmonary tuberculosis. However, these sites do not include the nasal part. Generally, patients with pulmonary tuberculosis show symptoms of the respiratory system and systemic symptoms. The most common respiratory symptoms include coughing and phlegm production for more than two weeks. Some patients may also experience hemoptysis, with varying amounts from mild to severe. A few patients may also experience chest pain. Additionally, patients with caseous pneumonia or significant pleural effusion may experience difficulty in breathing. Systemic symptoms of tuberculosis include fever, mainly characterized by afternoon tidal fever, with some patients exhibiting high fevers, and other general symptoms such as loss of appetite, weight loss, night sweats, and fatigue. However, the majority of patients with pulmonary tuberculosis do not exhibit nasal symptoms, meaning a runny nose is generally not a manifestation of tuberculosis. It could be possible that a tuberculosis patient might also have other infections or causative diseases, such as allergic rhinitis.

Does the BCG vaccine prevent tuberculosis?

The BCG vaccine primarily prevents infection by the tuberculosis bacillus, so it can prevent pulmonary tuberculosis. The protective effect of the BCG vaccine is mainly achieved through inducing a cell-mediated immune response. After vaccination, a primary infection is formed, which is processed by macrophages that transmit the antigen information to immune-active cells, leading to the differentiation and proliferation of T cells and the formation of sensitized lymphocytes. When the body is re-infected with the tuberculosis bacillus, the macrophages and sensitized lymphocytes are activated, causing a specific immune response in the body, thereby resisting the infection by the tuberculosis bacillus. Therefore, the BCG vaccine mainly prevents pulmonary tuberculosis.

Does tuberculosis cause fever in its initial stage?

Tuberculosis is caused by an infection of the lungs by the bacterium Mycobacterium tuberculosis, and it is a very common infectious respiratory disease clinically. Typically, the early stage of tuberculosis is accompanied by mild fever to varying degrees, usually occurring in the afternoon, along with coughing, expectoration of blood, chest tightness, shortness of breath, and even chest pain, weight loss, fatigue, and night sweats as accompanying clinical symptoms. In the early stages, the diagnosis of tuberculosis in patients is generally made through these specific clinical symptoms, along with some sputum culture and chest X-ray examinations. Usually, most patients with early-stage tuberculosis will experience symptoms of low-grade fever, but these patients have a characteristic of fever that occurs in the afternoon and does not require antipyretics as it can return to normal by itself in the evening.
