Day after day I treat smokers in my podiatry clinic, and they are shocked that smoking actually affects their feet.  They think that smoking may cause lung problems during thier lives but do not understand that it is the cause of their leg cramping, inability to walk for long distances (sometimes only a block or two), and in some cases, their severe foot and toe pain. Our heart pushes blood through a series of blood vessels that bring nutrients and oxygen to all areas of our body.  Thus, the feet get oxygen through this system of blood vessels.   Smoking causes blood vessels to narrow and the blood does not flow well through them.  The carbon monoxide in cigarettes kills the cells in the blood vessels,which allows fat to fill the walls of the vessels.  This contributes to thickening of the vessels or "hardening of the arteries."  When the arteries harden, they are no longer able to effectively and efficiently push blood throughout the body. 

If the feet do not get adequate blood flow (and oxygen), the following may happen:  thin, unhealthy skin; thick and irregular nails; pain;  cramping;  inability to walk for long distances; wounds that do not heal; and gangrene.  Poor circulation to the feet is a very dangerous situation and can lead to amputations when it gets severe. 

It is important to quit smoking, stay active, and maintain a healthy diet.  If you are diabetic, keeping your blood sugar within the normal range of 80-120 mg/dL is essential.  Additionally, controlling blood pressure and cholesterol levels will help keep your blood circulating.
