Patients with bronchial dilatation can eat wolfberry, sea cucumber, ginseng, snow lotus and other tonic. Because patients with bronchiectasis have recurrent lung infections for many years, their physical quality is relatively poor and their immunity is relatively low, so they need to take supplements to improve their body’s ability to resist diseases and replenish the nutrients needed by their bodies. The above mentioned supplements have a better effect of replenishing qi and blood in traditional Chinese medicine, which can improve the patient’s physical quality, improve body functions, reduce the risk of respiratory infections, and thus reduce the chances of recurring infections in bronchiectasis. At the same time, in the daily diet, we should pay attention to not eat spicy, stimulating, greasy, indigestible food. The above foods can not only aggravate gastrointestinal reactions, but also do not benefit the disease of bronchiectasis itself.
