According to the C.O.P.D. Foundation, approximately 24 million Americans are affected by C.O.P.D. C.O.P.D. stands for chronic obstructive pulmony disease. C.O.P.D. is not a specific condition, but rather a group of diseases affecting the lungs, including emphysema and chronic bronchitis. In most cases of C.O.P.D., breathing difficulties are a result of lung damage and blocked airways. There is currently no cure for C.O.P.D., but it may be possible to develop an effective C.O.P.D. care plan that helps to relieve symptoms.
