It is wildly known that smoking is harmful to the lung and heart vessels
which can cause cancer in lung or cardiovascular disease. However, how many
people have the knowledge that smoking can also do harm to our kidneys and cause Chronic Kidney Diseases?
More than 4,000 noxious chemical compound produced by each cigarette is
likely to enter the lung and then to be one part of the blood circulation. As we
know, kidneys should filter and excrete the wastes of the body, so the aromatic
amines (tar for instance) and acrolein in the cigarette also should be expelled
out of the body via kidneys, during which, the kidneys will be damaged a
lot.
◆ Being the main cause of craving of tobacco, nicotine in the cigarette
(0.5-2.7 mg/cigarette) is a kind of strong excitant which can stimulate the
nervous centralis and refresh oneself. Meanwhile, nicotine can help to increase
the heart rate as well as the blood pressure, and then leading to cardiovascular
disease. The blood coagulation leaded by it is a reason for the blocking of the
vessels which can decrease the blood volume in the kidneys and exacerbate
Chronic Kidney Diseases.
◆ In addition, the carbon monoxide (CO) in the cigarette (400ppm/per
cigarette) is a kind of toxin which can interfere the exchange of the oxygen
without color and smell, and it can also impede the combination of the oxygen
and protoheme by resulting in anoxia in the body. In a normal person, the CO in
the blood should be less than 1%, but that in a smoker may be as high as 15%. If
this condition lasts for long, the blood can be blocked and influence the mind
and our judgment; further more, the accumulation of the fat makes the renal
burden heavier than before.
◆A long-term smoking makes the blood pressure changeable, and the blood
vessels uptight, which can broke the Immunotherapy microcirculation gradually.
As for the patients with kidney disease, smoking is not only a destroyer of the
blood circulation and oxygen supply, but also a causer of cancer, includes Renal
Cell Carcinoma, Transitional Cell Carcinoma, Carcinoma of Urinary Bladder.
Smoking is closely related to the data of renal damage, especially the decrease
of GFR and appearance of proteinuria. That is why the patients with Chronic Kidney Disease should be more cautious if they are smokers.
