Tuberculosis can actually be completely cured, primarily through anti-tuberculosis treatment. If it is confirmed to be active tuberculosis, systematic and standardized anti-tuberculosis treatment is required. Through scientific and reasonable anti-tuberculosis treatment and taking medication on time and according to guidelines, most tuberculosis patients can be cured, with a cure rate reaching 85%. The treatment includes an intensive phase of anti-tuberculosis treatment and a consolidation phase, with the total course of treatment being about six months. After being cured, it is not easy to relapse, but it is essential to take medications on time, adjust nutrition, modify work and rest schedules, and rest well.

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 tuberculosis relapse?

Tuberculosis can relapse, and the answer is definitely yes. In clinical practice, we see many patients who have had tuberculosis and, years later, experience a recurrence of the disease, even multiple recurrences. However, the probability of this is generally not high. As long as everyone follows the doctor's instructions for standard anti-tuberculosis treatment and completes the full course of treatment, most patients can be cured. However, there are a few people whose treatment process is not standard, or who stop taking their medication on their own, and these actions can increase the risk of tuberculosis recurrence.

Can people with tuberculosis eat lamb?

Tuberculosis is a very common infectious disease in our country. After contracting tuberculosis, symptoms often include coughing, phlegm, hemoptysis, chest pain, low fever, night sweats, fatigue, poor appetite, and weight loss. Generally speaking, as long as one is not allergic to mutton, it can be consumed. However, if the patient has significant poor appetite and weak digestive function, it is better to eat less or avoid mutton to prevent worsening the symptoms due to indigestion. If the digestive function is still relatively good, eating mutton is alright as it is nutritious and can provide energy, benefiting the patient's recovery.

Tuberculosis is transmitted through the air.

The transmission of tuberculosis primarily depends on understanding its causative agent, which is the tubercle bacillus, also known simply as the tuberculosis bacillus. The main source of infection in tuberculosis is from patients who test positive for tuberculosis bacillus in their sputum. The respiratory tract is the principal route of transmission for tuberculosis patients. When patients who test positive for bacillus in their sputum cough, expel sputum, sneeze, or even speak loudly, they generate a large amount of droplets containing the tuberculosis bacillus. These bacteria can remain suspended in the air for a relatively long time. In poorly ventilated indoor environments, they may stay airborne for up to five hours. Healthy individuals can contract respiratory infections upon inhaling these bacteria. Furthermore, a very small portion of patients are infected through consuming milk or other dairy products from cows with tuberculosis.

How is tuberculosis treated?

The primary treatment for tuberculosis is still chemotherapy, also simply called chemo, but the chemotherapy for tuberculosis is completely different from the anti-tumor chemotherapy we talk about in cancer, and the medications are also completely different. There are about more than ten anti-tuberculosis drugs, which can be divided into first-line and second-line drugs, and currently, there are third-line drugs under research. Chemotherapy for patients with pulmonary tuberculosis should be started early and administered in combination. The types of combined medication for patients with pulmonary tuberculosis generally involve three or more drugs. Some patients may exhibit drug resistance or intolerance to some drugs' side effects, and thus, second-line drugs may be used. Additionally, some patients, due to special conditions, may require four or five types of anti-tuberculosis drugs. It is crucial to strictly follow medical advice regarding how to medicate and treat. Furthermore, patients with pulmonary tuberculosis must ensure complete medication adherence, as the treatment duration for tuberculosis is quite long, typically requiring at least six months, and some patients may need one or even two years. Regular medication intake is very important because some patients might experience symptoms like coughing up blood or others, such as those with pleurisy, who might develop pleural effusion. Therefore, treatments targeted at other symptoms are necessary. Patients who cough up blood might need hemostatic drugs, while those with severe hemoptysis may even require interventional surgery. Some with tuberculous pleurisy might need to have pleural effusion drained. Additionally, some patients with pulmonary tuberculosis might experience adverse reactions to medications, such as liver or kidney failure, visual impairment, or numbness in the hands, which would require adjustments to their medication or changes based on their complications. Treatment should also be targeted toward these adverse reactions.
