Optimization of Nutritional State on the Outcome of Patients With Acute Exacerbation of Bronchiectasis

Bronchiectasis is a chronic respiratory condition characterized by the abnormal and permanent dilation of the bronchi, leading to recurrent respiratory infections, chronic cough, and significant morbidity. The disease has gained increasing recognition due to its rising prevalence and the substantial burden it places on healthcare systems . Recent studies have highlighted the importance of nutritional status in managing chronic respiratory diseases, including bronchiectasis. Malnutrition is prevalent among patients with bronchiectasis, particularly those experiencing frequent exacerbations. It has been shown that underweight patients have lower lung function and may face worse clinical outcomes compared to those with normal weight . Specifically, a study found that underweight individuals had a significantly lower forced expiratory volume in one second (FEV1) compared to their normal-weight counterparts, indicating a direct correlation between nutritional status and respiratory function .
