Smoking
Smoking is highly injurious to health, as it leads to high blood pressure, which is among the primary causes of kidney disease. People who smoke frequently can suffer from blockages in blood vessels. The blockage of blood vessels does not let enough blood to flow through them towards kidneys thus depriving the kidneys of the adequate blood flow. The shortage of blood flow towards kidneys can damage the kidneys in the longer run and can lead to kidney disease.
