Bronchiectasis is a complication mainly caused by chronic inflammation of the respiratory tract and is clinically difficult to treat. Symptoms can be alleviated through certain medications or physical manipulations. First, it's important to maintain clear airways and choose medications that can dilute mucus. During the acute phase of inflammation, antibacterial drugs should be chosen for treatment, such as penicillin, which can be administered via muscle injection or intravenously. Surgery is the only curative treatment for bronchiectasis. (Medication use should be based on specific circumstances and under the guidance of a doctor.)
