Diabetes is a long-term condition caused by too much glucose (sugar) in the blood.

 

In the UK, approximately 2.9 million people are affected by diabetes. There are also thought to be around 850,000 people with undiagnosed diabetes (NHS Choices).

Left untreated, diabetes can cause many health problems. Large amounts of glucose can damage blood vessels, nerves and organs.

 

Even a mildly raised glucose level that doesn't cause any symptoms can have damaging effects in the long term.

Nerve damage can lead to sensory neuropathy (loss or limited feeling in the foot).  A podiatrist will check a patient's foot for sensation at each visit.

 

Blood vessel damage will reduce the amount of blood getting to the end of the foot, which can increase healing times and reduce the body's ability to fight off infections when a cut or damage has occured to the leg or foot.
