Does smoking affect the liver?

Speaking of the harm of cigarettes, many friends know that it can harm the lungs, and some friends also know that smoking can cause worse skin for women. But do you know that the harm of smoking to the human body is not limited to these, it even has certain harm to the human liver. If you are not very clear about the impact of smoking on the liver, you can read the introduction in this article. This article will make a detailed analysis of the harm of smoking to the liver.

First, nicotine: As we all know, the main harmful substance in cigarettes is nicotine (nicotine). Nicotine affects the liver mainly in the following aspects:

(1) When smoking, the nicotine concentration in the blood increases. Nicotine is mainly metabolized in the human body by the liver and lungs, which increases the workload of the liver.

(2) Nicotine can excite the sympathetic ganglia and adrenal medulla, causing vasoconstriction and increasing blood viscosity, making it easy to form blood clots and thus block small arteries. This will result in a reduced blood supply to the liver, affect the liver's nutrition, and be detrimental to the stability of liver disease.

Second, carbon monoxide: Under normal circumstances, the human body's red blood cells combine with oxygen molecules in the blood and then deliver the oxygen molecules to various organs of the body.

Carbon monoxide enters the blood through the lungs and quickly binds to red blood cells (the ability of carbon monoxide to bind to red blood cells is 200 times that of oxygen molecules). Once bound, it is not easy to separate, occupying the red blood cells that transport oxygen molecules. This will result in a decrease in the number of red blood cells that can actually transport oxygen, causing liver hypoxia, which is not conducive to the repair and regeneration of liver cells.

Third, hepatopulmonary syndrome: Patients with chronic viral hepatitis and cirrhosis may experience pathological and functional changes such as shortness of breath, dyspnea, pulmonary edema, interstitial pneumonia, pleural effusion, hypoxemia, etc., collectively referred to as hepatopulmonary syndrome.

I believe that everyone is aware of the impact of smoking on the liver. From the above, we know that smoking not only harms the liver, it also increases the incidence of lung cancer and liver cancer. Therefore, if you want to stay away from cancer, the first thing you must do is to quit smoking. Especially for women who want to keep themselves beautiful, they must start by quitting smoking. I hope that everyone can take this as a warning.

It is well known that smoking can cause emphysema. It is estimated that 80%-90% of COPD morbidity and mortality are related to smoking. Smoking reduces people's lung function, especially for those who smoke a lot, the reduction in lung function is more obvious.
