In people with diabetes, if high blood glucose levels are experienced over a period of years, our blood vessels can become damaged which can lead to plaque forming in the blood vessels rendering them unable to deliver a sufficient amount of blood to neighbouring cells.
People with diabetes should receive an annual foot examination. The foot check should include a test for circulation in the feet. Your doctor may wish to confirm the presence of peripheral arterial disease by using a test called the ankle brachial pressure index test (ABPI test). The ABPI test involves using a Doppler probe to measure the ratio between the flow of blood in your upper arm and the flow of blood at your ankle.
