Emphysema is a lung disease that can get worse over time. Emphysema is a type of chronic obstructive pulmonary disease (COPD). It's usually caused by smoking. Primarily causes shortness of breath. Emphysema changes the anatomy of the lung in several important ways. The cause of emphysema is damage to the small air sacs and small airways in your lungs. This damage obstructs airflow when you exhale. Emphysema is defined as abnormal permanent enlargement of air spaces distal to the terminal bronchioles, accompanied by the destruction of the walls and without obvious fibrosis. Three described morphological types of emphysema are centriacinar, panacinar, and paraseptal.First type is centriacinar emphysema, begins in the respiratory bronchioles and spreads peripherally. Also called centrilobular emphysema, this form is associated with long-standing cigarette smoking and predominantly involves the upper half of the lungs. Second type is panacinar emphysema, which destroys the entire alveolus uniformly and is predominant in the lower half of the lungs. This type of emphysema generally is observed in patients with homozygous alpha1-antitrypsin (AAT) deficiency and . Third type is distal acinar emphysema (also known as paraseptal emphysema), preferentially involves the distal airway structures, alveolar ducts, and alveolar sacs. The process is localized around the septae of the lungs or pleura. Although airflow frequently is preserved, the apical bullae may lead to spontaneous pneumothorax. Giant bullae occasionally cause severe compression of adjacent lung tissue. Estimates show that 4-6% of white male adults and 1-3% of white female adults have emphysema or COPD. Men have a higher mortality rate than women.
Emphysema is characterized by focal destruction limited to the airspaces distal to the respiratory bronchioles on the other hand. Main emphysema symptoms are shortness of breath and oter Signs and symptoms of emphysema include is Cough, Loss of appetite and weight loss and Fatigue. The most important step in any treatment plan for smokers with emphysema is stopping smoking; it's the only way to stop the damage to your lungs from becoming worse. But quitting is never easy, and people often need the help of a comprehensive smokingcessation plan. Nicotine replacement products and prescription medications may help curb the irritability, depression and sleep problems that can occur during the first few weeks after quitting smoking. Other emphysema treatments, which focus on relieving symptoms and preventing complications, include is bronchodilators drugs can help relieve coughing, shortness of breath and trouble breathing by opening constricted airways, but they're not as effective in treating emphysema as they are in treating asthma. AAt may help slow lung damage in people with an inherited deficiency of the protein. Lung transplantation is an option if you have severe emphysema and other options have failed. Respiratory infections such as acute bronchitis, pneumonia and influenza are a leading complication of emphysema; infections increase the amount of sputum you produce and make breathing problems worse. Broad-spectrum antibiotics may help relieve these symptoms. Supplemental oxygen-Using oxygen at home may provide some relief. Various forms of oxygen are available as well as different devices to deliver them to your lungs.
