Generally speaking, pregnancy and childbirth have little effect on the effectiveness of chemotherapy. However, after a woman becomes pregnant, certain changes in metabolism, endocrine function, blood circulation, respiratory function and immunity will occur. After pregnancy, as the months increase, the uterus gradually increases, and the huge uterus compresses the lungs, which can compress the lung lesions and play the therapeutic role of artificial pneumoperitoneum, which is a favorable side. However, the whole lung volume decreases, and the breathing is shallow and fast, which affects the ventilation and air exchange function of the lungs, which is unfavorable to the recovery of tuberculosis disease. In addition, in early pregnancy, there are varying degrees of gestational reactions that reduce nutritional intake, thus weakening maternal resistance. Late pregnancy is prone to gestational toxicity and bleeding, which can also worsen the condition. After delivery, the body’s resistance is significantly weakened, and the deterioration rate of tuberculosis is high. Therefore, it is not advisable for patients with tuberculosis to become pregnant and have children before they are cured. After anti-tuberculosis treatment, if there is no tuberculosis bacteria in the sputum, the cavity is closed, most of the lesions are absorbed, there are no clinical symptoms, and the disease does not change after six months to a year of observation after the course of treatment, pregnancy is possible with the consent of the doctor.
