BENGALURU: If you have diabetes and your blood sugar levels are too high, it can damage your nerves or blood vessels. You may not feel a cut, a blister or a sore. Blood vessels damage means that the feet does not get enough blood and oxygen. Injuries to the foot can cause ulcers and infections and in severe cases it may even lead to amputation. It is harder for your foot to heal, if you do get a sore or infection.

In individuals suffering from diabetes, neuropathy which is peripheral nerve dysfunction can be combined with peripheral artery disease (PAD), leading to poor blood circulation in the extremities (diabetic angioplasty). Owing to which the individuals suffering from diabetes are unable to feel pain. This translates into injuries being undetected for prolonged periods, resulting in minor injuries and alterations becoming gateways to potentially disabling infections, which may necessitate lower limb amputation. One of the main causes of non-traumatic amputation in diabetics is due to foot infections.

Foot care in diabetics is of paramount importance as it goes un-noticed leading to infections, and untreated infections can lead to gangrene, which in turn may require amputation.
Diabetes induced neuropathy causes the skin to dry up, and dry feet crack making it easy for the germs to enter the body. Nerve damage can also lead to changes in the shape of the patients feet ( Charcot foot), which makes previously comfortable shoes hard to walk in. This causes friction leading to calluses and bunions exposing skin to germs.
