Cough with weight loss is usually one of the symptoms of tuberculosis, a chronic infectious disease caused by Mycobacterium tuberculosis that can affect many organs, with tuberculosis infection of the lungs being the most common. The most common form of tuberculosis infection is in the lungs. People who excrete the bacilli are an important source of infection. Infection with Mycobacterium tuberculosis does not necessarily cause disease, but may cause clinical morbidity when resistance is reduced or cell-mediated metaplasia is increased. If diagnosed promptly and treated appropriately, most patients can be cured clinically. Diet is also important for the prognosis of patients. The following are suitable foods for patients with cough with weight loss for reference: 1. Patients with cough with weight loss should consume nutritious, protein-rich foods, such as the intake of rich soy products, because the disease consumes more human protein. 2, cough with weight loss patients should consume foods rich in vitamins to increase the body’s immunity and clear the lungs of detoxification, such as yams, lilies, fungus, lotus root, pears, blood oranges, lemons, apples, coconut milk, figs, sugar cane, grapefruit, dates and various other fresh vegetables and fruits. 3. Patients with cough with weight loss should consume foods rich in calcium, iron and zinc, thus helping the TB lesions to calcify, replenish blood (especially hemoptysis patients need appropriate amount of blood) and heal physically. 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. 4, cough with weight loss patients will increase daily energy consumption, so they should consume higher-calorie foods for energy replenishment, such as fresh dates, coconut, dried cinnamon, raisins, walnuts, longevity fruit, peanuts, etc., unless they are suffering from obesity or cardiovascular disease.
