Chronic obstructive pulmonary disease (COPD) is common and should be suspected in any patient with chronic dyspnea, cough, or sputum with a history of exposure to tobacco or harmful particles. Spirometry is used for diagnosis. Full evaluation includes the severity of obstruction and clinical data, following the Global Initiative for Chronic Obstructive Lung Disease guidelines. Although the only treatments that have an impact on mortality are tobacco cessation, pulmonary rehabilitation and, for advanced disease, oxygen therapy, new symptomatic treatment have recently been made available. The duration of antibiotic and corticosteroid treatment for exacerbations has been shortened. The new diagnostic and management recommendations are summarized in this article.
