Bronchiectasis is a common chronic medical condition. Patients usually present with symptoms such as fever, coughing up blood, chronic cough, and loss of appetite. The treatment of bronchiectasis generally starts with the cause of the disease. Common causes of bronchiectasis include bacterial infections, foreign bodies entering the airways, and immune problems. If a patient has a cough with sputum that has affected respiratory function, bronchodilators can usually be used to improve airflow restriction and help remove secretions from the body, which can be very effective for some patients with reversible airflow restriction. Removal of excessive secretions is important in the treatment of bronchiectasis in the elderly and can prevent asphyxia from occurring. Amoxicillin, quinolones, and intravenous aminoglycosides can be given to patients with mild symptoms; for patients with chronic croup, a longer course of antibiotics is recommended. Meanwhile, for the treatment of bronchiectasis, life care is crucial. It is important to keep warm and avoid colds, which can easily cause infections in the body and induce bronchiectasis attacks; at the same time, it is important to avoid the intake of cold, spicy and irritating foods; it is recommended not to smoke or drink alcohol; it is possible to take appropriate physical exercise to help improve the body’s resistance. Bronchial dilatation can be treated from two aspects: medicine and life.
