The allergic state of the pediatric organism is higher, especially the highly allergic state of the vascular system, and the permeability of the vascular wall is enhanced. When the immunity of the organism is weakened, mainly the primary focus or caseous lymph nodes next to the tracheobronchus invade the blood vessels, and a large number of tuberculosis bacilli invade the blood circulation, producing bacteraemia with the route, number, frequency and length of interval of their invasion, and invading the interstitial lung and lung parenchyma through the vessel wall and intima to form corn nodules. Due to the different routes of invasion of tuberculosis bacilli into the bloodstream, the sites and types of bacillary nodules occur differently. When the tubercle bacilli invade the pulmonary artery and bronchial artery and enter the small circulation through the right heart, it causes cornual tuberculosis. When the tuberculosis bacilli invade the pulmonary veins and enter the large circulation through the left heart and spread to the peripheral organs, such as the lung and brain, liver, spleen, kidney and intestine, as well as the meninges, pleura, peritoneum and pericardium, then it causes systemic cornual tuberculosis. Tuberculosis patients should consume foods rich in calcium, iron and zinc to help calcify tuberculosis lesions, replenish blood (especially hemoptysis patients need the right amount of blood) and heal their bodies. Such as celery, amaranth, tomatoes, apricots, red dates, purple cabbage, black fungus, black sesame, soy products, golden needles, etc. It is worth mentioning that tuberculosis is not suitable for eating spinach, because spinach is rich in oxalic acid, which will combine with calcium in the body to form calcium oxalate, affecting the absorption and storage of calcium in the body. Tuberculosis will increase daily energy consumption, so you should consume high-calorie foods for energy replenishment, such as fresh dates, coconut, dried cinnamon, raisins, walnuts, longevity fruit, peanuts, etc., unless you are suffering from obesity or cardiovascular disease. Tuberculosis patients should stop smoking and drinking, and should not consume spicy and irritating foods or foods that produce phlegm on fire. Because most patients with tuberculosis have a strong deficiency fire, hot or even some warm foods can cause an increase in symptoms. Especially chili, pepper, cinnamon, pepper, ginseng and other spices.
