Smoking causes diseases such as emphysema, COPD, lung cancer, coronary heart disease, stroke, and chronic bronchitis. Cancer is the most serious consequence, with nine out of ten lung cancer deaths caused by smoking. Quitting smoking can reduce the risk of developing smoking-related diseases.
Some of the more common smoking-related diseases are emphysema, chronic obstructive pulmonary disease (COPD), and lung cancer. Coronary heart disease, stroke and chronic bronchitis are other diseases associated with cigarette smoking. There are thousands of toxic chemicals that exist in the compound of a single cigarette that can lead to disease.
The most serious consequence and risk factor of cigarette smoking is cancer. Nine out of ten deaths from lung cancer are said to be caused by cigarette smoking. Other diseases related to smoking are different forms of cancer such as pancreatic, prostate and liver. More commonly, cancer of the mouth or larynx is also related to smoking. Although lung cancer accounts for more smoking-related illnesses and deaths than other cancers combined, they can all play a significant role.
Emphysema constricts the lungs and airways, as does COPD. Long-term smoking can scar the lining and tissue of the lung, causing permanent damage and lifelong breathing difficulties. Shortness of breath, wheezing, and the presence of a chronic cough are all symptoms of smoking-related diseases associated with COPD.
Chronic bronchitis typically causes coughing up phlegm and frequent inflammatory problems involving the bronchi. There may be great difficulty when the individual tries to exhale due to the fact that the lungs have to work harder to contract. Those who suffer from such smoking-related illnesses are typically more susceptible to upper respiratory infections.
Heart disease caused by cigarette smoking is commonly found. As the smoker continues the habit over a period of time, plaque is likely to build up in the arteries of the heart. When the arteries start to harden, blood flow can become blocked and this can lead to many serious complications. If left untreated, it can lead to death from cardiac arrest. Smoking marijuana has also been linked to causing risk factors for heart disease, although some experts deny this reasoning.
Cigarette smoking has been shown to be a cause of stroke, because nicotine has the effect of causing blockage of blood vessels in the brain. When blood vessels are unable to function properly, the brain also loses its capacity and a stroke can occur. Stroke victims can often be left with permanent disabilities in speech and motor coordination, as well as paralysis.
For people who want to reduce the risk of developing smoking-related diseases, there are effective ways to quit smoking. Smoking cessation aids and alternatives are readily available. There are also smoking support groups that provide advice and techniques to help you kick the habit for good.
