Cystic fibrosis patients need to keep a distance from other people, mainly because patients with low resistance, very easy to get infected, keep a distance from others, can reduce the risk of infection. 1. Cystic fibrosis is a kind of autosomal recessive disease that invades many organs, mostly develops in childhood, patients can have repeated respiratory infections, and eventually involve many organs of the body, which can be manifested as coughing, coughing up sputum, diarrhea, abdominal pain, fever, etc., and in severe cases, it can lead to hypoxia and respiratory difficulties. 2. As cystic fibrosis patients are sick for a long time, their bodies are over-consumed and often accompanied by malnutrition, and their resistance and immunity are low, which makes them susceptible to external pathogenic factors, so they need to pay attention to keep a certain distance from others in their daily life, so as to reduce the risk of infection and avoid aggravation of the disease. 3. For cystic fibrosis, commonly used drugs include azithromycin, ibuprofen, glucocorticosteroids, etc. For people with severely reduced lung function, lung transplantation is also needed. Cystic fibrosis patients should follow the doctor’s instructions for treatment. Meanwhile, close contact with others should be avoided on a daily basis to reduce the risk of self-infection. In terms of diet, it is also necessary to pay attention to the supplementation of protein, fat, calories and trace elements to ensure sufficient nutritional requirements, and also through moderate exercise, such as slow walking, which is also effective in enhancing physical fitness.
