Chest tightness, shortness of breath, dizziness, smoking

Although cigarettes are a substance that has a certain impact on human health, since they contain substances such as nicotine and tar that can make people addicted, and can also temporarily paralyze the human mind and relieve the high mental pressure, many people still have a certain obsession with cigarettes. However, some people find that they experience chest tightness, shortness of breath, and dizziness after smoking. So what is the cause of this phenomenon?

1. Does smoking cause chest tightness, shortness of breath and dizziness?

There are many reasons for chest tightness, shortness of breath and dizziness, such as cor pulmonale, multiple heart diseases or poor blood circulation. But no matter what, smoking is a contributing factor to lung disease, because smoking can seriously damage the health of the upper respiratory tract and lungs, resulting in insufficient oxygen absorption by the lungs and causing breathing difficulties. Therefore, it is recommended that you do not smoke for the sake of your health. If you often feel chest tightness and shortness of breath, you should go to the hospital for a check-up as soon as possible to find out the cause and take good care of yourself.

2. What are the harms of smoking to the heart?

Medical data shows that nicotine and carbon monoxide in smoke can cause blood vessels to harden. Because the binding force of carbon monoxide to hemoglobin is about 250 times greater than that of oxygen, the carboxyhemoglobin formed can reduce the oxygen-carrying capacity of the blood. This causes edema of the inner wall of the artery, hinders blood flow, and provides conditions for the deposition of cholesterol, which leads to arteriosclerosis over time.

Nicotine can cause the body's tissues to release "catecholamines", causing the heart rate to increase and blood pressure to rise. This can not only lead to high blood pressure, but also due to the accelerated heart rate and large blood output, it is easy to cause myocardial hypoxia and cause an attack of coronary heart disease.

The incidence of coronary heart disease increases with the amount of smoking. Most deaths from coronary heart disease in people under 60 are related to smoking. Like lung cancer, deaths from coronary heart disease decrease with smoking cessation. It decreases significantly one year after quitting smoking. After 10-20 years, the condition is similar to that of non-smokers. Although the mortality rate of coronary heart disease is lower than that of lung cancer, coronary heart disease is more common than lung cancer. Therefore, the number of deaths caused by smoking is more than that of lung cancer. Sudden death from coronary heart disease in men under 50 is mainly caused by smoking.
