Diabetes and the circulatory system

When blood glucose levels from diabetes become uncontrolled, the blood vessels in certain parts of the body become damaged.


When blood glucose levels become uncontrolled, and the glucose levels in the blood remain dangerously high, the blood vessels in certain parts of the body become damaged.

This affects the body’s ability to circulate blood as effectively as usual.

The lower legs and feet are particularly susceptible to this, therefore a tingling sensation in these parts of the body should be a warning to all diabetics. If this is experienced, immediate medical attention is needed. Foot infections, coupled with reduced circulation could easily lead to gangrene and the necessity for amputations. - (Health24, February 2010)
