If you are not cured after one year of tuberculosis treatment, you need to be alert to the possibility of drug-resistant tuberculosis if you are on an anti-tuberculosis treatment regimen under the guidance of a physician and taking your medication regularly, and further drug-sensitivity testing for tuberculosis bacteria is recommended. If the drug sensitivity test suggests drug-resistant TB, the anti-TB treatment regimen needs to be adjusted, so that the anti-TB treatment cycle is longer, usually taking 1-2 years, or even longer. Of course, if the tuberculosis is pan-drug-resistant, the treatment is very difficult because none of the tuberculosis drugs are sensitive, and such tuberculosis bacteria are difficult to kill. In the process of anti-tuberculosis treatment, in addition to drug treatment, it is also necessary to pay attention to rest, strengthen nutrition and enhance physical fitness, which is beneficial to the treatment of tuberculosis.
