What vascular damage does smoking cause? Smoking increases the incidence of cardiovascular and cerebrovascular diseases, which is now increasingly recognized. Domestic data show that the incidence of cardiovascular and cerebrovascular disease is 2.5 times higher in people who smoke a lot, smoke a lot, and smoke for a long time than in non-smokers. Why smoking is prone to cardiovascular disease? Because tobacco contains a substance called nicotine, which has a toxic effect on the human body, smoking will be inhaled nicotine, prompting the adrenal glands to release a large number of catecholamines, so that blood vessels spasm, heart rate increases, blood pressure rises. On the other hand, due to the increased secretion of adrenaline, can make the blood cholesterol increased, the cell gap increased, fatty deposits form atherosclerosis. In addition, the smoke of smoking contains carbon monoxide, the concentration of which can reach 3-5%, which is absorbed into the blood through the lungs and can combine with the hemoglobin of red blood cells to form carboxyhemoglobin. Carboxyhemoglobin lost the ability to carry oxygen, which will make the oxygen content of the blood is greatly reduced, lack of oxygen can reduce the elasticity of blood vessels, there is also nicotine in tobacco can promote the aggregation of red blood cells, white blood cell deposition, so that the blood viscosity increases, blood flow slows down, so it is easy to cause blood vessel thrombosis. Smoking less does not reduce the occurrence of vascular disease, and quitting smoking is the only effective way. Quitting smoking is not only good for healthy people, but also for people who may already have smoking-related diseases. What happens after I quit smoking? When you quit smoking, the toxic effects of the toxic substances in the smoke on the body can gradually decrease, and most lesions improve to varying degrees, helping to reduce the morbidity and mortality of cardiovascular and cerebrovascular disease. It has been reported that the odds of having a stroke begin to decline after 2 years of quitting smoking and are the same as non-smokers after 5 years. There are many ways to quit smoking, mainly: 1, psychological victory, smokers really recognize the harm of smoking to their own bodies and the impact on the health of family members, especially children, with the will and perseverance to resist the addiction in order to achieve the purpose of quitting. 2, acupuncture, quit smoking candy, quit smoking tea and so on with the role of the use of some alternatives to tobacco. 3, drugs, bupropion can help to quit smoking, to be used under the guidance of a doctor or professional. 4, smoking cessation clinics, there are now some hospitals opened smoking cessation clinics, can help smokers under the guidance of professional staff for effective cessation.
