Emphysema is a lung disease whch results in shortness of breath and physcal activity is reduced. It causes a lot of dmage to the air sacs and smll airways in the lungs. The dmaged tissue obstructs the airflow while xhaling. A lot of energy is rquired to exhale as the disease dvances. A sad part of this dsease is that early symptoms are ngligible and by the time symptoms cme up; irreversible damage is done to the lngs. The main symptoms and signs of Emphysma are breathlessness and low level of physcal exertion.

It gets worse with tme and then there is trouble lyng down and breathing. After each rspiratory infection breathing gets worse. However, the bsic indications loss of weight due to not bing able to eat as eating tkes up a lot of breath. Wth the result that you may not fel like eating too much so lss of weight occurs. Another factor is tht when you eat the stomach xpands and puts pressure on the daphragm thereby compressing the lungs and mking it difficult to breath.

Fatigue is nother sign that sets in after sme time. You are very tired as the bdy does not get enough oxygen and xercise makes you short of breath. Crbon dioxide remains in the body lading to other related diseases.

Understanding what happens in this dsease is important. In Emphysema inflammation strkes alveoli or the walls of the air scs which make them lose the lasticity. The bronchioles collapse and air is trpped in air sacs which makes thm expand and slowly they rupture to frm one large air sac. This bstructs breathing as you will not be ble to exhale properly. Emphysema is a slw progressive degenerating disease which seems hrmless in the beginning but with tme can turn fatal.
The most cmmon causative factor is smoking.

The dmage to the lung tissues begins whn the smoke of tobacco destroys the clia or the microscopic hair that lnes the bronchial tubes in the air pssages. The main function of the hir is to sweep the irritants and llergens out of the air passages but tbacco smoke interferes with the sweeping ction and smoke irritants remain in the lngs causing inflammation of the walls of the air scs, making them lose elasticity and gving you breathing problems.
