Most cases of chronic obstructive pulmonary disease caused by long term smoking. Inhaling lung irritants like pollen, air pollution, dust, fumes and other chemicals can also Contributing to this disease. Early signs of this disease is a chronic cough and coughing up mucus secretion. Other associated symptoms may include difficulty breathing, chest tightness or discomfort, wheezing and other respiratory symptoms. A patient with COPD are more prone to constant chest infections than healthy individuals. Thus Spake, COPD is a major cause of medical complications and death in many countries. In medicine, there is no cure for COPD. To put in simple words, damage to the airways can not be reversed again. But there are some treatment options that can help manage symptoms of shortness of breath. The most effective approach to treatment of COPD is to quit smoking, one can opt for nicotine replacement therapy to cope with nicotine withdrawal symptoms. Likewise, avoid exposure to chemicals and lung irritation as far as possible. Other treatment options for COPD include oxygen therapy (if necessary) and drugs such as corticosteroids and antibiotics (for a chest infection)Pathophysiology of lung diseases are very complex and not fully understood. A resistance to air flow can be caused by many factors such as mucociliary disorders, inflammatory response and structural changes. In summary, blockage or narrowing of the airway can be caused by loss of elasticity of the airways, damage or inflammation of the airway wall, excess mucus secretion in the airways and decrease in surface area for gas exchange. According to medical research, a chronic inflammatory response in the airways is a major factor for the development of COPD. This suggests that the inflammatory response due to COPD and asthma are different from them.
