There are three common reasons for the enlargement of tuberculosis lesions: first, the patient’s compliance in taking anti-tuberculosis drugs is poor, eating one meal and not eating another, which leads to the enlargement of tuberculosis lesions and makes it difficult to control the symptoms of tuberculosis; second, the patient is infected with drug-resistant Mycobacterium tuberculosis, in which case conventional anti-tuberculosis drug therapy is not effective and the lesions are likely to increase; third, the patient does not strengthen nutritional support therapy in the process of anti-tuberculosis, such as staying up late and overworking. Third, the patient does not strengthen the nutritional support treatment in the process of anti-tuberculosis, and the life pattern is not good, such as often staying up late and overworking. In addition, eating some spicy, stimulating and greasy food leads to malnutrition and further decrease in body resistance, which in turn leads to lesion enlargement.
