What are the physical harms of tobacco and what are the physical harms caused by tobacco?

The health hazards of tobacco are indisputable medical conclusions. Smoking kills 6 million people worldwide each year, more than AIDS, tuberculosis and malaria combined. Tobacco contains 69 carcinogens, and there is ample evidence that smoking can cause lung cancer, oral cancer, nasopharyngeal malignancy, laryngeal cancer, esophageal cancer, stomach cancer, liver cancer, pancreatic cancer, kidney cancer, bladder cancer, and cervical cancer.

There is also evidence that smoking can cause colorectal cancer, breast cancer, and acute leukemia.

Smoking can lead to a variety of respiratory diseases. There is good evidence that smoking can lead to chronic obstructive pulmonary disease and adolescent asthma, and increase the risk of tuberculosis and other respiratory infections.

Smoking impairs vascular endothelial function. There is good evidence that smoking causes coronary heart disease, stroke, and peripheral artery disease, and smoking cessation may reduce the risk of morbidity and mortality from these diseases.

Smoking can damage genetic material and adversely affect the endocrine system, fallopian tube function, placental function, immune function, maternal and fetal cardiovascular system, and fetal tissue and organ development. There is good evidence that smoking in women reduces the chances of conception, leading to placenta previa, placental abruption, fetal growth restriction, low birth weight in newborns, and sudden infant death syndrome. In addition, smoking can lead to ectopic pregnancy and spontaneous abortion.

Smoking can also cause erectile dysfunction in men.

Smoking leads to hip fractures, periodontitis, cataracts, poor healing of surgical wounds, and respiratory complications after surgery, **aging. People with Helicobacter pylori infection can cause peptic ulcers. There is good evidence that smoking can lead to periodontitis and nuclear cataracts.

In addition, smoking can also lead to type 2 diabetes and increase the risk of macrovascular and microvascular complications in diabetic patients, affecting the prognosis of the disease.

Smoking is the largest preventable cause of disease and mortality in humans, and smoking cessation is the only way to reduce the health risks of smoking and reducing the risk of morbidity and mortality in smokers, nor do they obtain health benefits. Studies have shown that quitting smoking at age is associated with a 10-year increase in life expectancy, respectively, compared to continued smoking.

Smoking is a disease that is medically known as chronic nicotine dependence addiction. Tobacco can bring about diseases such as lung cancer, chronic respiratory diseases, coronary heart disease, etc. Even e-cigarettes are harmful to the human body.

Cardiovascular disease. The higher the amount of cigarettes, the higher the risk of heart attack. The risk of sudden cardiac death is significantly higher in smokers than in nonsmokers.

2.Malignancy. In addition to lung cancer, smoking is a major risk factor for many cancers such as leukemia, oropharyngeal cancer, laryngeal cancer, esophageal cancer, gastric cancer, pancreatic cancer, kidney cancer, bladder cancer, and cervical cancer.

Quitting smoking directly reduces the risk of developing these cancers. Even if patients already have smoking-related cancer, quitting smoking reduces their risk of developing a second smoking-related malignancy. 3.

Other diseases. In addition to this, smoking can cause a wide range of other diseases. It can cause smokers to be more susceptible than normal to influenza, pneumonia, diabetes, osteoporotic fractures, reproductive disorders, gastroduodenal ulcers, gingivitis, periodontitis, etc.

The damage caused by tobacco to a person's body is long-term, and some of the damage is irreversible. It is common knowledge that smoking is harmful to health, and the damage to the lungs is direct, thus forming a vicious circle and bringing a series of physical harm.

Tobacco is harmful but not beneficial, so it is recommended to stay away from tobacco as much as possible. Tobacco causes physical harm, which is briefly described as follows.

1. Long-term smoking is easy to cause respiratory diseases, and the smoke produced by tobacco enters the human body through the respiratory tract, seriously harming the respiratory tract and directly acting on the respiratory system and lungs such as bronchi, trachea. Induce bronchitis, emphysema, lung failure and other diseases.

Tobacco contains a large amount of nicotine, which will promote vasoconstriction, causing coronary artery constriction of heart blood, thereby affecting the blood of myocardial tissue, and inducing coronary heart disease and cardiovascular disease.

Tobacco is also one of the culprits of lung cancer, and tobacco tar is one of the carcinogens, and smoking can easily induce lung cancer.

Smoking, smoke and fire will affect eyesight, rough and other conditions. Tobacco can cause malformation and miscarriage in women who are suspicious. Tobacco is harmful to your health, so stay away from tobacco for the sake of your own health and that of your family.

Smoking is harmful to the body, and the range of lesions caused by smoking is relatively wide, and the common harms are as follows:

1. Respiratory diseases: Smoking can lead to inflammation of the upper respiratory tract, including pharyngitis, rhinitis, sinusitis, laryngitis, etc. Smoking can cause tracheitis, bronchitis, chronic bronchitis, emphysema, bullae, chronic obstructive pulmonary disease, etc., and in severe cases, cor pulmonale.

Some patients who smoke for a long time can have co-infection and bronchiectasis. Smoking can lead to malignant tumors of the respiratory tract, including lip cancer, tongue cancer, nasopharyngeal cancer, laryngeal cancer, and broncholung cancer.

2. Digestive system diseases: It can cause esophageal cancer, gastric cancer, pancreatic cancer, gallbladder cancer, colon cancer, etc., and the above tumors are closely related to smoking. Smoking can lead to a decrease in digestive function, abnormal secretion of gastric digestive juices, and peptic ulcers, such as gastric ulcers and duodenal ulcers.

Smoking affects the absorption of nutrients, such as the absorption of trace elements, and systemic nutrition can be problematic;

3. Cardiovascular and cerebrovascular diseases: smoking can lead to cardiovascular and cerebrovascular diseases, resulting in arteriosclerosis, hypertension, myocardial ischemia, stroke, etc.;

4. Nervous system diseases: Smoking can lead to nervous system problems, tobacco dependence, irritability, palpitations, lack of energy, anxiety, depression, sleep disorders and a series of problems.

1. Cause respiratory damage: Cause chronic obstructive pulmonary disease, the greater the amount of smoking, the longer the number of years, and the younger the age of smoking, the higher the risk of this disease. In addition, smoking can lead to asthma and poorly controlled asthma, increasing the risk of respiratory infections, tuberculosis, interstitial lung disease, venous embolism, pneumoconiosis and other diseases;

2. Increase the prevalence of malignant tumors: especially lung cancer, oral cancer and oropharyngeal tumors;

3. Cause atherosclerosis: cause coronary heart disease and cerebrovascular disease;

4. Increase the prevalence of diabetes: It will also increase the risk of diabetic macrovascular and microvascular complications.

The harm of tobacco to the human body is mainly due to the fact that tobacco contains three dangerous chemicals, tar, nicotine and carbon monoxide. Tar can be concentrated mainly into a viscous substance in the lungs of the human body, while nicotine is an addictive drug that is absorbed by the lungs and mainly acts on the central nervous system. Carbon monoxide lowers haemoglobin and transports oxygen throughout the body.

Therefore, the risk of lung cancer in patients who smoke is more than 14 times higher than that of normal people. In addition, long-term smokers are also prone to oral cancer, laryngeal cancer, and esophageal cancer. The chance of developing bladder cancer is also more than twice as high as that of normal people.

At the same time, patients who smoke also have a much higher chance of heart disease than normal people. Smoking can lead to chronic bronchitis, emphysema, and an increased risk of hypertension.

Tobacco can cause respiratory diseases, especially damage to the lungs and bronchitis. The effects of tobacco are that it can induce physical hazards such as bronchitis, lung failure, emphysema, and even lung cancer.

Tobacco Team. Damage caused by the body is a long-term process, cumulative, and irreversible. Smoking is harmful to health has become a social consensus, and the damage caused by tobacco to the lungs is immediate, and forms a vicious circle, bringing a series of bad consequences to the body.

Tobacco contains a large amount of nicotine, which will promote the constriction of blood vessels, make the coronary arteries of the heart blood constrict, thereby affecting the blood of myocardial tissue, and induce cardiovascular disease and coronary heart disease.

Tobacco tar is a carcinogen. After long-term smoking, the lungs are damaged, and lung lesions are induced to produce lung cancer. Long-term smoking also affects the roughness of **, vision loss.

The harm of tobacco to women can lead to infertility, fetal malformations and miscarriages in pregnant women, which are extremely harmful to the physical and mental health of girls.

Tobacco is harmful to the human body and has no benefit, so it is recommended to stay away from tobacco and second-hand smoke. For the sake of your health and the health of your family, quit smoking as soon as possible.

Cigarettes mainly contain three components, tar, nicotine, nicotine, and carbon monoxide, which are harmful to the human body, and the harm is as follows:

1. Tar can be deposited on the mucosa, smoking can be deposited on the oral mucosa and tongue through the mouth, and can be deposited in the pharynx, trachea, and even on the alveoli, tar can be deposited in the mucosa for a long time to induce cancer, deposition in the oral cavity can lead to oral cancer, deposition in the pharynx can lead to throat cancer, deposition in the trachea can lead to bronchopulmonary cancer, which is the harm of tar;

2. Nicotine is a central stimulant, some people will feel very energetic and excited after smoking, which is the effect of nicotine, but although nicotine excites the nerves, it will also become addictive, as long as you don't smoke, you will feel uncomfortable, which is dependent on nicotine, and long-term contact will lead to mental problems, such as palpitation, drowsiness, insomnia, irritability, poor temper, and some mental symptoms are related to nicotine dependence and toxicity;

3. Long-term inhalation of carbon monoxide will lead to hypoxia in the human body, the most common impact is the heart and brain, and the lack of oxygen in the heart and brain will cause cerebral infarction, myocardial infarction, heart disease, cerebrovascular disease, etc., all of which are harmful caused by smoking.

Smoking has all kinds of harms but no benefits, and if you have the conditions to quit smoking, you should quit smoking as soon as possible.

The harms of tobacco include causing cancer, shortening life expectancy, and affecting the health of women and children.

The main substance of tobacco is nicotine, which has strong central nervous toxicity and organ toxicity. Smoking produces large amounts of toxic chemicals when burned. Many other toxic substances, radioactive substances and carcinogens pose a serious threat to health.

Introduction:

Tobacco (scientific name: Nicotiana tabacum L.).) is a plant of the genus Tobacco in the Solanaceae family, an annual or limited perennial herb, with glandular hairs all over; The roots are stout.

The stems are tall and slightly lignified at the base. Leaves oblong-lanceolate, lanceolate, oblong-rounded or ovate, apex acuminate, base tapering to the stem ear-like and semi-obstalked.

inflorescences apical, conical, multifloral; The peduncle is 5-20 mm long. The capsule is ovate or oblong, about the same length as the calyx. The seeds are round or broadly rounded, about mm in diameter, brown. Flowering and fruiting in summer and autumn.

The smoke produced by tobacco combustion contains at least more than 2,000 harmful and defeating components, such as benzopyrene, benzanthene, nitrosamines, polonium-210, cadmium, arsenic, etc. When smoking, most of the cigarette smoke is inhaled into the lungs, and a small part enters the digestive tract along with saliva. Some of the harmful substances in the smoke stay in the lungs, and some enter the blood circulation and flow to the whole body.

Under the synergistic action of carcinogens and carcinogens, normal cells are damaged, and cancer can be formed. The harmful components in cigarette smoke include carbon monoxide, nicotine and other alkaloids, amines, nitriles, alcohols, phenols, alkanes, olefins, carbonyl compounds, nitrogen oxides, polycyclic aromatic hydrocarbons, heterocyclic compounds, heavy metal elements, organic pesticides, etc.
