The slow recovery of tuberculosis is mainly related to the nature of the disease, the pathogen, treatment and other factors. 1. The nature of the disease: tuberculosis itself is a chronic infectious disease, the formation of the disease itself is a long process, then the healing of nature is not an overnight thing, the speed of healing will naturally be slow. 2. Pathogen: the pathogen that causes tuberculosis is Mycobacterium tuberculosis, compared to ordinary pathogens, such as bacteria, viruses, etc., Mycobacterium tuberculosis toxicity to be stronger, so the difficulty of completely killing the pathogenic bacteria is naturally the greater, which makes tuberculosis slower to heal. 3. Treatment: slow recovery from tuberculosis and treatment are also closely related, although tuberculosis patients can be cured through the use of anti-tuberculosis drugs, but the use of anti-tuberculosis drugs to cope with tuberculosis need to follow the early, appropriate amount of the whole course of the drug, the combination of choice, improper use of drugs will cause drug resistance, resulting in refractory tuberculosis, thus increasing the difficulty of treatment, resulting in treatment cycle. Individuals should face tuberculosis in a correct attitude and way, strictly follow the medical advice to standardize the treatment of the disease, cure the disease as soon as possible, and get rid of the harm of tuberculosis.
