Lung injury in emphysema is a result of inflammatory and destructive processes in response to cigarette smoke exposure. In patients with chronic obstructive pulmonary disease (COPD), pro-inflammatory and pro-destructive pathways are activated, at times independent of smoke exposure, and other anti-inflammatory, anti-oxidant, or repair pathways are down-regulated, all resulting in lung destruction.

This is not a reversible state, and usually the lung pathological changes will continue to deteriorate if the lungs are exposed to the same pathogens that caused the initial damage (for example- smoking). WebMD - Better information. Better health. Obstructive lung disease is a category of respiratory disease characterized by airway obstruction.Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself. Emphysema is a long-term condition that usually progresses slowly over a number of years.

Dessa och andra associerade sjukliga förändringar försämrar lungfunktionen of COPD, Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017.

With emphysema, the sacs break apart and merge into each other, producing holes in the lung. If the emphysema has caused extensive damage, it is sometimes called bullous emphysema.

Emphysema is a chronic medical condition (most often caused by smoking and air pollution) where lung tissue is damaged and traps air inside the lung. Learn h

The ICD-11 lists chronic bronchitis with emphysema (emphysematous bronchitis) as a "certain specified COPD". Cause. Most cases of chronic bronchitis are caused by tobacco smoking.

Chronic obstructive pulmonary disease includes chronic bronchitis and emphysema, and can be related to smoking or exposure to harmful substances. A number of occupational lung diseases can be caused by substances such as coal dust, asbestos fibres, and crystalline silica dust. Diseases such as bronchitis can also affect the respiratory tract. Emphysema due to alpha-1 antitrypsin deficiency Computed tomography of the lung showing emphysema and bullae in the lower lobes of a subject with type ZZ alpha-1 antitrypsin deficiency. There is also increased lung density in areas with compression of lung tissue by the bullae.

Diseases such as bronchitis can also affect the respiratory tract. Onset of lung problems is typically between 20 and 50 years old. This may result in shortness of breath, wheezing, or an increased risk of lung infections. Complications may include chronic obstructive pulmonary disease (COPD), cirrhosis, neonatal jaundice, or panniculitis.

From Wikipedia, the free encyclopedia A focal lung pneumatosis is a pocket of air (pneumatosis) in the parenchyma of the lungs, larger than the alveolus. A focal lung pneumatosis can be classified by its wall thickness. Blebs or bullae are also known as focal regions of emphysema.

Congenital lobar emphysema is a rare respiratory disorder in which air can enter the lungs but cannot escape, causing overinflation (hyperinflation) of the lobes

Subcutaneous emphysema can be caused by medical procedures and medical conditions that cause the pressure in the alveoli of the lung to be higher than that in the tissues outside of them.
