Stay one step ahead in the Management of your Diabetes

In diabetes foot care one of the main causes of ulceration in the diabetic foot is poor tissue oxygenation, which is caused by blocking of the large or small vessels. This can lead to very slow wound healing and make infection more likely, which can in severe cases lead to gangrene in the foot. Obviously early intervention in these cases is a priority as loss of limb can be a main cause of early morbidity. Where the circulation is severely compromised it is very difficult for the infection to clear. Foot ulcers affect 1 in 10 of Diabetes sufferers. It is really important to receive professional diabetes foot care from a Podiatrist.

Common Causes of Foot ulceration

  • Extrinsic pressure from tight shoes.
  • Prolonged heel pressure.
  • Intrinsic pressures from chemical mediators of infection within the body.
  • Walking in bear feet and treading on a pin or sharp object which may not be felt due to loss of sensation.
  • Foot type- high arch or flat feet etc.
  • Calluses
  • Blisters
  • Athletes foot

Important steps to avoid foot ulcers with Diabetes foot care

  • It is important that if you have poor circulation that your feet are checked on a regular basis by either a Podiatrist or other medically trained professional. The lower limb foot pulses will be checked, with the skin and nails for any signs of poor foot circulation.
  • Proper accommodating footwear must be worn to avoid any shearing forces, which causes blistering of the skin.
  • Check your feet daily for any changes in skin colour, blisters and calluses etc. All these could lead to ulceration and possibly gangrene, with loss of limb.
  • Orthoses to correct any problems with your gait or excessive foot pressures.
  • Padding’s or strapping’s for excessive foot pressure or shearing forces which can lead to ulceration.
  • Heel pads to protect your heels.
  • Use Foot cream daily to avoid dry and cracked skin, which can be a common source of foot infection.
  • Dry your feet thoroughly, especially between the toes to avoid infection.
  • Control your Diabetes with regular exercise, healthy eating and an aggressive treatment regime to control the blood sugars.
  • Avoid smoking as this can fir up the arteries and cause heart problems.
  • Check your shoes for any signs of wear and inside for foreign objects such as sharp edges.

Loss of sensation – Diabetic Neuropathy

Loss of sensation can develop in the feet over time. This condition is known as Diabetic neuropathy which manifests itself as peripheral neuropathy and usually affects the sensory nerves in the legs. Again it is important to have a regular check for this condition by a podiatrist or other medically trained professional.

Why it is vital to check for loss of sensation

If the nervous system becomes damaged it is possible for the feet to become numb. This can become painful in the early stages with a condition sometimes developing known as painful neuropathy. It is possible that your skin may be damaged through trauma or infection, even callus formation or standing on a pin and you could be totally unaware of the seriousness of the situation. As a foot ulcer could easily develop and you may be unaware due to the loss of sensation. Neuropathy can cause the heels to crack and the skin to dry out and pressure from daily walking may go unnoticed. Your Podiatrist will grade your feet from low risk to high risk, if you are more at risk of ulceration.

To recap it is important that you have a regular diabetes foot care check six monthly to yearly and check your feet and inside your shoes daily to avoid any potential problems.
