Can tuberculosis be cured? First, we need to understand that tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis. In recent decades, many drugs have been developed for anti-tuberculosis treatment. As long as one strictly follows the doctor's advice and adheres to the medication schedule, the vast majority of tuberculosis cases can be completely cured. However, it is crucial to recognize that the treatment duration for tuberculosis is lengthy. Typically, patients need at least six months, while those with recurrent tuberculosis might need eight months. Some patients with multidrug-resistant tuberculosis may even need to take medication for two years. Therefore, it is essential to undergo standardized anti-tuberculosis treatment. Nevertheless, some patients, due to non-adherence to medical advice, irregular medication intake, or discontinuation of treatment on their own without completing the full course, may face treatment failure. In severe cases, this can lead to multidrug resistance, significantly prolonging the treatment duration and drastically reducing the cure rate, and may even cause infertility. Additionally, some patients may experience severe adverse reactions to tuberculosis drugs, such as significant liver and kidney damage, or have comorbidities like diabetes, liver cirrhosis, or HIV/AIDS. Others may develop severe complications, such as cardiopulmonary disease or respiratory failure, which greatly reduce their chances of recovery and can even lead to death.
