After years of research and progress in the treatment of tuberculosis, the treatment of tuberculosis is no longer difficult and, in general, more than 95% of patients with tuberculosis can be treated successfully. However, why are some patients not treated for TB? There are generally three reasons for this: First, the disease is not treated early. If patients do not see a doctor in time after the symptoms of tuberculosis appear, or do not get a correct diagnosis after seeing a doctor, the treatment is delayed, making the tuberculosis disease progress, become extensive and serious, even causing serious damage to the lung tissue structure and cardiopulmonary dysfunction, which not only makes treatment very difficult, but also brings lifelong pain due to serious damage to cardiopulmonary function even if the tuberculosis is controlled. Second, the patient’s treatment plan and treatment process also have a great deal to do with whether tuberculosis can be cured. If TB patients are treated with the wrong combination of drugs, or the wrong dosage of drugs, or the wrong method of treatment, or the wrong course of treatment, it will affect the effectiveness of TB treatment, and even lead to treatment failure. Third, drug resistance of Mycobacterium tuberculosis. Patients infected with drug-resistant tuberculosis bacillus or drug-resistant tuberculosis bacillus due to irregular treatment greatly reduces the success rate of treatment.
