Individuals with tuberculosis, if accompanied by a cold and rhinitis, will also experience a runny nose. However, simple tuberculosis, without any upper respiratory infections or rhinitis, does not lead to a runny nose. Therefore, it is important to accurately analyze the issue. Common symptoms of tuberculosis include persistent coughing, coughing up phlegm, low-grade fever, night sweats, bloody sputum, chest tightness, and difficulty breathing, among others. Once tuberculosis is definitively diagnosed, it is essential to commence timely and scientifically sound anti-tuberculosis treatments. Most cases can be completely cured.

Does tuberculosis get inherited?

Is tuberculosis hereditary? Tuberculosis is not a hereditary disease; it is an infectious disease. Infectious diseases and hereditary diseases are two completely different concepts. Tuberculosis is generally infectious, which means that in a family, if parents are infected, they can easily transmit the tuberculosis bacteria to their children or others around them. Therefore, many people might mistakenly believe that tuberculosis is hereditary. However, this is not the case; tuberculosis is transmitted through the tuberculosis bacteria.

Does tuberculosis cause fever?

Does tuberculosis cause fever? Certainly, fever can occur. Fever is one of the most common clinical manifestations of tuberculosis, which can be mild or high fever. Most cases of tuberculosis mainly present as afternoon febrile flushes, or say, an evening low-grade fever. In a few cases, such as infectious pneumonia or more severe infections like tuberculous pleurisy, there can be high fever, and these fever episodes may last a long time and be recurrent, making them difficult to control.

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.

How to test for tuberculosis

To examine pulmonary tuberculosis, it is essential to understand that it pertains to tuberculosis changes in the lung tissue, airways, bronchi, and pleura. The pathogen causing tuberculosis is Mycobacterium tuberculosis, also known as the tubercle bacillus. There are multiple tests available for people with pulmonary tuberculosis, as the disease can vary based on location and type. Therefore, such patients generally require numerous tests. The most commonly used are imaging studies for the chest, including X-rays and CT scans. In imaging studies, most patients will show some lesions, but there are instances where tuberculosis in the airways and bronchi might not be clearly visible on CT or X-rays, necessitating more invasive tests like bronchoscopy. Additionally, bacteriological examinations, such as sputum smear and pleural fluid smear, as well as culture for Mycobacterium tuberculosis, are typically conducted for patients. Nowadays, hospitals equipped with the necessary facilities conduct molecular biological tests, namely nucleic acid testing for Mycobacterium tuberculosis DNA. Furthermore, some patients with complex conditions may require a histopathological biopsy, commonly referred to as tissue sampling, at the site of the lesion to observe under a microscope for characteristic changes indicative of tuberculosis. There are also immunological tests that assist in diagnosing tuberculosis, such as the gamma interferon release assay (commonly known as the T-SPOT), tuberculin skin test, and traditional antibody tests against Mycobacterium tuberculosis.

Can people with tuberculosis drink alcohol?

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.
