Can smoking kill you?
Smoking can cause various brain diseases, reduce oxygen and blood circulation in the brain, lead to cerebral vascular bleeding and occlusion, and lead to paralysis, mental decline and stroke. The cause of stroke is that smoking leads to cerebral vasospasm, which makes blood coagulation easier. Smokers are twice as likely to have a stroke as nonsmokers.
laryngeal
Smoking can cause laryngeal cancer. Laryngeal cancer patients are mostly male.
Heart and blood vessels
Studies have found that smoking can increase the viscosity of platelets in the blood, making it easier for blood to coagulate, thus easily forming thrombus in the coronary artery. At the same time, smoking will also increase the low-density cholesterol in the blood, making it easy for fatty substances to deposit in blood vessels and form coronary atherosclerosis. If the coronary artery hardens, its lumen will become thinner. Once the blood coagulates inside, the artery will be blocked. At this time, oxygen can not be sent to this part of the myocardium, and myocardial cells will fail and die due to lack of oxygen. This is a myocardial infarction. Local myocardial infarction can cause angina pectoris, while large-scale myocardial infarction can make people go into shock or die because of sudden cardiac arrest. This is acute myocardial infarction. Smoking will constrict blood vessels, slow down the circulation of blood and oxygen, and eventually lead to thickening of blood vessel walls, leading to coronary heart disease and stroke. Smoking will completely block the blood circulation of hands and feet, leading to amputation.
Doctors advise smokers to quit smoking immediately if they have high blood pressure, hyperlipidemia, heart disease or family history of heart disease, because smoking will increase your risk of myocardial infarction by dozens of times. The death rate of heart disease caused by smoking accounts for 25% of the total. The prevalence of smokers over 50 has doubled. The prevalence rate of smokers under 50 years old increased 9 times, reaching 14 times.
lung
Smoking can cause lung cancer. 90% of the total mortality rate is caused by smoking. The prevalence rate of a person who smokes ten cigarettes a day is ten times that of a non-smoker. Damaged cells can't return to normal. The initial symptoms will not be found until the cancer cells spread to blood vessels and other organs. Up to now, lung cancer has caused the largest number of human deaths, and early detection is almost impossible. The survival rate of patients diagnosed with lung cancer is less than 5% after 3 years and almost zero after 5 years. Doctors advise smokers to have a chest X-ray every 3 to 6 months. If there are symptoms such as dry cough, bloodshot sputum, dull pain in the chest, fever, etc., you should not take it lightly. They should go to the hospital immediately for sputum exfoliated cells examination. Only in this way can the possibility of early detection of lung cancer be increased. Smoking can also cause emphysema, and toxic substances accumulated in the bronchi of the lungs will hinder the normal exhalation of the air inhaled by the human body, causing lung cells to expand or burst, resulting in difficulty breathing. The patient with severe emphysema is in great pain. In order to inhale enough oxygen, they have to stand up and gasp at high frequency. Even on the flat ground, they should walk slowly. Some more serious patients have to rely on oxygen bags to keep alive. In their life, they must concentrate all their efforts on one simple action-breathing.
Some doctors think that compared with emphysema, lung cancer should be regarded as a very kind disease, because it makes people suffer for a much shorter time.
stomach
People with gastrointestinal diseases, smoking is enough to make gastrointestinal diseases worse. People with gastric ulcer or duodenal ulcer will slow down the healing of ulcer and even become chronic diseases. Smoking can stimulate the nervous system, accelerate the secretion of saliva and gastric juice, make the gastrointestinal tract often tense, and lead to the loss of appetite of smokers. In addition, nicotine can also contract gastrointestinal mucosal blood vessels and reduce appetite.
skeleton
The recovery period of fracture of smokers is longer than that of non-smokers. It may be that nicotine and carbon monoxide contained in cigarettes slow down the process of bone regeneration. Nicotine constricts blood vessels and reduces blood flow to new bones. The carbon monoxide inhaled during smoking also reduces the speed at which oxygen enters the body. Smoking can lead to osteitis and back pain. Smoking more than ten cigarettes a day will double the prevalence of periostitis. Most people with severe back pain are addicted to smoking, because smoking will reduce the blood flow of the articular disc and the articular disc will degenerate early. Smoking can lead to arthritis. Smoking a pack of cigarettes a day will increase the prevalence rate by 50%. Female smokers are more likely to suffer from fractures and arthropathy after menopause. Smoking will lead to faster bone loss. Women smoke a pack of cigarettes every day from adolescence to menopause, and their bones are 5% to 10% less than those of non-smokers. When smokers enter menopause, the bone loss rate is faster. Smoking can interfere with estrogen, which is an important hormone in bone development.
bronchus
Smoking is the main cause of chronic obstructive tracheal disease. Because smoking can cause the cilia of bronchial epithelial cells to become shorter and irregular, cause dyskinesia, reduce local resistance and be susceptible to infection.
liver
Smoking will increase the burden on the liver. Regular smoking will affect the lipid metabolism of the liver, increase blood lipid, decrease benign cholesterol and increase malignant cholesterol. This has caused the burden of detoxification function of the liver to increase.
intestines
Smoking can lead to colon cancer. The risk of this kind of cancer is directly proportional to the amount of smoking. Research shows that although quitting smoking can reduce the risk of heart disease, lung cancer and other diseases, the risk of colon cancer is still high.
ocular region
Smoking can lead to cataracts and affect vision. Research shows that there are twice as many cataract patients who smoke more than one pack a day as those who never smoke.
genital system
Smoking inhibits the nerve center of the spinal cord, making men's sexual desire weak, and because smoking can make blood vessels contract and spasm, it causes peripheral blood circulation disorder. Therefore, smoking is the main cause of impotence. Australia and Canada have printed this information directly on cigarette packets. In addition, smoking will affect sperm motility and increase abnormal sperm, and it will take three to six months to return to normal after quitting smoking. If you want a smart and healthy child, baby experts advocate that you must give up smoking for three to six months.
