Can I smoke before a physical examination? 6 major harms of cigarettes to human body

Smoking is no longer just a habit of male friends. Many female friends have also gradually become addicted to smoking. Especially because of the great pressure in life and work, people like to use smoking to relax their brains. However, many friends do not know whether smoking before a physical examination will affect the results of the physical examination. Then let me tell you whether you can smoke before a physical examination?

A health check-up is a proactive examination of the entire body at a hospital or a special physical examination center when you are in good health. The main purpose is to detect potential diseases through the examination so that preventive and treatment measures can be taken in time. The health conditions of many middle-aged people who think they are healthy are very not optimistic. More than 50% of middle-aged people suffer from various diseases to varying degrees, and the vast majority of them have high blood sugar, high blood lipids, high cholesterol, and high blood pressure.

Regarding physical examination common sense, we should know that one week before the physical examination, it is best to quit drinking and smoking, eat a light diet, and avoid spicy and irritating foods, because these activities will cause the body's blood, cardiovascular and cerebrovascular states to become extremely unstable, resulting in inaccurate physical examination indicators. This is because different cigarettes release different chemicals when they are lit, but the main ones are chemicals such as tar and carbon monoxide.

(1) Aldehydes, nitrides, and olefins: these substances are irritating to the respiratory tract.

(2) Nicotine can stimulate the sympathetic nerves and cause damage to the vascular endothelium.

(3) Amines, cyanides and heavy metals, all of which are toxic substances.

(4) Benzopyrene, arsenic, cadmium, methylhydrazine, aminophenol and other radioactive substances. All these substances are carcinogenic.

(5) Phenolic compounds and formaldehyde, etc. These substances have the effect of accelerating carcinogenesis.

(6) Carbon monoxide can reduce the ability of red blood cells to transport oxygen throughout the body.
