Some People With Diabetes Lose Limbs

It is due to poor circulation that is usually caused by a patient not managing their condition through diet, exercise and/or medication. Loss of limbs DOES NOT happen to all diabetics; but, diabetics have to pay close attention to any cuts or changes in their limbs, especially the feet.

Diabetes causes high levels of glucose in the blood, which can damage just about any organ in the body. It affects the nerves in the feet, a condition called peripheral neuropathy, so patients lose sensation. It also causes vascular changes, hardening and clogging the arteries so the feet don't get enough oxygenated blood. That means patients might not feel an irritation until it breaks the skin, allowing bacteria to enter the wound. Because the blood supply is poor, the body has a diminished capacity to fight the infection, so the wounds don't heal. Gangrene often sets in if the wound goes untreated for too long, resulting in amputations.
