Not being able to hold your breath for 60 seconds is not tuberculosis. TB is a common infectious disease that is usually not self-tested and requires a doctor to diagnose it with a combination of symptoms, signs, and tests. People with low immunity are especially susceptible, such as the elderly, infants and young children, the weak, malnourished, and those with chronic illnesses. TB can be diagnosed in a number of ways, including observation of symptoms, such as coughing, coughing up sputum for more than 2 weeks, or respiratory symptoms such as blood in sputum, dry cough, increased sputum, irritating cough, hemoptysis, chest pain or even dyspnea, etc., which are suspicious of the possibility of tuberculosis. Chest X-rays can also be used for routine diagnosis of tuberculosis, which can help determine the location of the lesion, its morphology, and its relationship with the surrounding tissues, and can effectively show whether there are lesions in the lungs and the extent of the lesions. If tuberculosis is diagnosed, self-protection should be practiced and targeted treatment should be carried out under the guidance of a doctor.
