Patients with bronchiectasis can eat mutton, as in traditional Chinese medicine, mutton is considered a warming and tonifying food. It generally benefits conditions like cold-induced cough, chronic bronchitis, and deficiency-cold asthma. Patients with bronchiectasis, who often suffer from repeated lung infections and have lower immune function, are generally weaker, so consuming an appropriate amount of mutton can be beneficial. However, it should not be consumed in excess as mutton can cause heatiness or indigestion, which are particularly detrimental for individuals with bronchiectasis.
