Diabetes is fast becoming a major heath concern, with 6% or 1.2 million Australians reported to have diabetes (types 1 and 2) in 2014-15 (1). Podiatrists play an important role in preventing complications in the feet of people living with diabetes. Because the feet are the furthest point from the brain and the heart, complications from diabetes often occur there first. This is one of the many reasons doctors may recommend foot checks as part of routine diabetes care (2).

Diabetes Foot Health

What an assessment involves

Podiatry is an integral part of health care in the management of diabetes. We’ve also written about why you should get your feet checked here. In an assessment, a set of routine questions are asked to assess overall all health.

These questions will also explore how well your diabetes and blood sugars are being controlled, and to see if there are signs of complications. The clinical tests performed in an appointment are aimed at detecting change in nerve function, circulation/blood flow, movement and flexibility of feet (3).

Circulation and Blood Flow Assessment

As with the blood vessels in your heart, the arteries in your legs can become hard or clogged with fatty deposits. This can reduce circulation to your feet and affect the delivery of nutrients and oxygen to the muscles and tissues.

Podiatry Diabetes Foot Health

To assess blood flow to the feet, a podiatrist may feel for pulses on your feet, or look at the colour and health of your skin and nails. A Doppler (ultrasound device) may also be used to listen to the blood flow in your arteries to see how well the blood is travelling from your heart to your feet. Depending on the findings of these tests, the podiatrist may look to take your blood pressure in your ankle.

This happens exactly the same as how your doctor takes your blood pressure on your arm. This is called an Ankle Brachial Index or an ABI. By taking blood pressure at the ankle, podiatrists are able to compare the reading against the blood pressure in the arm. If the pressures are the equal (or close to equal) that indicates your feet are getting healthy blood flow.

Neurological (Nerve) Examination

Nerves are responsible for movement, feeling (sensation) and protective responses such as reflexes. They also have other important functions which are less well known, including; sweating, blood flow and proprioception (knowing the position of the body in space).

Diabetes may become problematic for nerve function when blood sugar levels are not well controlled. If sugar levels are too high for a prolonged period of time the nerves and nerve insulation (myelin) can be damaged.

Neurological examinations are designed to test these different functions. The most important neurological function for a diabetic, is to have protective sensation or the ability to feel light touch.

This is tested with a device called a monofilament which applies only 10 grams of pressure when touched to the skin. 50% of diabetics have lost this protective sensation. This is also referred to as peripheral neuropathy (4).

Other nerve functions a podiatrist may check include; reflexes, ability to feel vibration and detection of joint position. These tests should be performed with eyes closed so its only the nerves which can give your brain the information!

How to Prevent Complications

There are a number of easy things you can do to prevent complications with your feet.

Check your feet daily.

Scratches or blisters can become serious quite quickly. Particularly when you have poor blood flow or a loss of sensation as mentioned previously. It is as simple as setting up a mirror on the ground to have a look at the soles of your feet.

Alternatively, try using a phone or camera to take photos of your feet. This was you can see them in more detail and zoom in if required!

Foot Mirror

Dry in between your toes.

Moisture in between your toes can cause the skin to break down. This is important particularly when you have swelling, suffer from fluid retention or live in hot, humid climates. Once there is a breach in the skin, this can become painful and leave the foot prone to infection.

Being sure to dry in between your toes after every shower is a good way to prevent any of these complications. You could consider an application of metholated spirits (wiped over area with a cotton ball).  Alternatively,  a foot soak in Condy’s Crystals (potassium permenganate) to help dry out problem areas (5).

Wear appropriate footwear

Good shoes plays a very important role in preventing complications in diabetes. Particularly if there are problems with sensation. Footwear provides protection from trauma such as splinters and scratches.

Diabetes Foot Care

It is crucial that the shoes must fit well as to not cause issues such as blisters from rubbing or pressure sores from being too tight. Remember, before putting your shoes on check that they are free from rocks and any other loose debris!


Routine Checks

Your podiatrist should make recommendations on how frequently you should have a foot assessment. Depending on their findings it may be recommended that your feet are assessed either annually, 6 or 3 monthly.

These time frames are based on test results and are aimed at monitoring for changes and preventing complications. Complications can become serious suddenly, so your podiatrist may refer you to be managed by your GP or outpatient clinics at hospitals.

If managed in the hospital system, specialists such as orthopedic or vascular surgeons can be involved in care quickly if required.

Even if you do not have diabetes but are concerned about your feet, consider getting them checked by a podiatrist. Symptoms such as tingling or numbness in your feet, cramping while walking or when lying down, or a sore which is slow to heal should be checked out.

Remember, complications from diabetes can be prevented with appropriate care. When it comes to your feet, if in doubt – get them checked out!

About Claire Campbell

Claire graduated with a Bachelor in Podiatry from the Queensland University of Technology in 2017. Having recently moved from Brisbane, Claire is enjoying exploring Canberra and experiencing all that it has to offer. Claire also has a degree in Health Sciences with a Major in Public Health and Health Promotion. Previously she had be working in the field of mental health in Queensland's health department and at Griffith University in health research. Claire decided to make the switch from the head to the toes (mental health to podiatry) in order to have a greater direct impact on patient care, and she hasn't looked back since. Claire loves all things podiatry with a special interest in ingrown toe nails, orthotic therapy and paediatrics.
