The arteries become narrow, rigid or blocked. Due to atherosclerosis (narrowing of arteries), blood clots are formed, which increases the risk of cardiovascular diseases. Common cardiovascular diseases found in smokers are coronary thrombosis, cerebral thrombosis, coronary heart diseases, blockage in the legs (peripheral vascular disease) and cerebrovascular diseases such as stroke.
Chronic Obstructive Pulmonary Disease (COPD): It is a group of health conditions, which blocks airflow and causes difficulty in breathing. It causes health problems such as emphysema and chronic bronchitis. Emphysema is breathlessness that is caused by damage to alveoli (air sacs). Chronic bronchitis causes frequent coughing with a lot of mucus. Smoking is responsible for about 80% of COPD cases. Smoking increases the rate of decline in lung function three times the usual rate. Breathlessness starts due to decrease in lung function.
