The most important function of kidneys is filtering blood to remove all kinds
of harmful wastes, especially to remove creatinine and blood urea nitrogen. For
patients with Chronic Kidney Disease( CKD), their kidneys are damaged; the
quantity and quality of filtration decrease; the toxins cannot be removed and
will build up inside the body. These toxins may hurt all kinds of organs, which
will damage kidneys in turn.
Smoking is the number one preventable cause of death in most countries. It
also can lead to lung disease. For patients with chronic kidney disease, their
filtering functions decrease, smoke toxins cannot be removed easily and will
aggravate the burden of kidneys. In addition, lung disease may affect
kidneys.
Since 2003, a large number of clinical and experimental data about the
adverse renal effects of smoking have been published. These more recent data
together with evidence from experimental studies indicate that smoking is a
relevant risk factor, which can decline renal function.
Smoking can hurt renal vessels. The more you smoke the heavier hurt your
renal vessels will get. Smoking also can aggravate renal artery sclerosis, which
will actuate glomerulosclerosis.
The conclusion is that smoking is an important risk factor of Chronic Kidney Disease, and nephrologists have to invest more efforts to motivate patients to
stop smoking. Whether the renal function is damaged or not, people should give
up smoking, especially for patients with Chronic Kidney Disease.
