Bronchiectasis is caused by chronic suppurative inflammation and fibrosis of the bronchial tubes and their surrounding lung tissues, which destroys the muscular and elastic tissues of the bronchial walls, leading to deformation and persistent dilatation of the bronchial tubes. Typical symptoms include chronic cough, coughing up large amounts of purulent sputum and recurrent hemoptysis. The main causative factors are bronchial infection, obstruction and straining, and some have congenital genetic factors. Most patients have a history of measles, pertussis or bronchopneumonia. At the same time, bronchiectasis cannot be completely cured, because bronchiectasis is a structural lung disease, it is due to repeated chronic airway inflammation, resulting in inflammatory changes in the bronchial tubes, which leads to deformation and expansion of the airways, and this change is irreversible, and it is unlikely that this change will be restored to normal, so bronchiectasis cannot be completely cured. So how do we take care of bronchiectasis after treatment? 1, pay attention to weather changes, cold days should pay attention to keep warm, indoors is to ensure that the air can not be too dry, open the air conditioning to avoid the temperature is too low, to avoid getting cold and flu. 2, the patient should quit smoking, at the same time do not go to places with smoke, pay attention to indoor air circulation, avoid contact with smoke and irritating gas. 3, sputum volume is appropriate to take the position of drainage (such as lesions in the lower lobe of the bronchus to take the head down and feet high potential), 2 to 3 times a day, each time about 15 minutes. 4, hemoptysis should be gently cough out the blood, do not hold the cough to suffocate, or cough hard. 5.Patients and their families should use antibacterial drugs under the guidance and advice of doctors, and should not use them privately, abusively or for a long time. 6, acute bronchial dilatation patients should pay attention to rest, relief period can be made breathing exercises and appropriate physical exercise to enhance body resistance and immunity, family members should do a good job of supervision and encouragement. 7, eat more eggs, meat, fish, milk and fresh vegetables, fruits and vegetables. At the same time, patients should also maintain a good and positive attitude. Healthy and upward is conducive to the treatment of the disease.
