Smoke from cigarettes blocks self-healing processes in the lungs and consequently can lead to chronic obstructive #pulmonary disease (COPD), says a new study. Researchers at the #Helmholtz Zentrum München, partner in the German Centre for Lung Research (DZL), and their international colleagues have reported this finding in the American Journal of Respiratory and Critical Care Medicine.
Cough, bronchitis and breathing difficulties are the typical manifestations of COPD. Exact figures are not available, but estimates assume that 10 to 12% of adults over 40 years of age in Germany suffer from the disease. Experts estimate the national economic costs of the disease at almost six billion euros annually. Scientists around the world are attempting to discover how the disease develops and what biological adjustments can be made to stop it.
